Ready to kickstart your entrepreneurial journey? Let's begin!
Understanding how a plumbing company works
The very first step when exploring a business idea such as starting a plumbing company is to make sure you understand how the business operates and makes money (which is what we call the business model).
This will not only give you an initial idea of how profitable the business can be, but it will also enable you to make sure that this is the right business idea for you, given your skills, start-up capital and family or personal lifestyle, in particular.
The best ways to get to grips with the plumbing company's business model are to:
- Talk to plumbing company owners with experience
- Work a few months in a plumbing company already in operation
- Take a training course
Talk to plumbing company owners with experience
Experienced plumbing company owners have valuable insights and can provide practical advice based on their firsthand experiences.
They've likely encountered and overcome challenges that a newcomer might not anticipate. Learning from other’s mistakes can save you both time and money and potentially increase your venture’s chances of succeeding.
Work a few months in a plumbing company already in operation
Obtaining work experience in the industry can be a crucial factor in confirming whether you truly want to start a plumbing company, as it provides insight into the day-to-day activities.
For instance, if the working hours are longer than expected or if other business requirements don't align with your personal lifestyle or preferences, you might reconsider your entrepreneurial goals.
Even if you've decided that this business idea is a good fit for you, gaining work experience will still be valuable. It helps you better understand your target market and customer needs, which is likely to be beneficial when launching your own plumbing company.
Take a training course
Obtaining training within your chosen industry is another way to get a feel for how a plumbing company works before deciding to pursue a new venture.
Whatever approach you choose to familiarise yourself with the business, before going any further with your plans to open a plumbing company, make sure you understand:
- What skills are required to run the business (compare this with your own skills)
- What a typical week in the business is like (compare this with your personal or family life)
- What is the potential turnover of a plumbing company and the long-term growth prospects (compare this with your level of ambition)
- Your options once you decide to sell the business or retire (it's never too early to consider your exit)

Assemble your plumbing company's founding team
The next step to start your plumbing company is to think about the ideal founding team, or to go in alone (which is always an option).
Setting up a business with several partners is a way of reducing the (high) risk of launching a plumbing company since it allows the financial risk of the project to be shared between the co-founders.
This also allows the company to benefit from a greater diversity of profiles in the management team and to spread the burden of decision-making over several shoulders.
But, running a business with multiple co-founders brings its own challenges. Disagreements between co-founders are quite common, and these can pose risks to the business. That's why it's crucial to consider all aspects before starting your business.
To make an informed decision, we suggest asking yourself these questions:
- How many co-founders would increase the project's chances of success?
- Do you and your potential partners share the same aspirations for the project?
- What is your plan B in case of failure?
Let's examine each of these questions in detail.
How many co-founders would increase the project's chances of success?
The answer to this question will depend on a number of factors, including:
- Your savings compared with the amount of initial capital needed to launch the plumbing company
- The skills you have compared with those needed to make a success of such a project
- How you want key decisions to be taken in the business (an odd number of partners or a majority partner is generally recommended to avoid deadlock)
Put simply, your partners contribute money and/or skills, and increasing the number of partners is often a good idea when one of these resources is in short supply.
Do you and your potential partners share the same aspirations for the project?
One of the key questions when selecting your potential partners will be their expectations. Do you want to create a small or large business? What are your ambitions for the next 10 or 15 years?
It's better to agree from the outset on what you want to create to avoid disagreements, and to check that you stay on the same wavelength as the project progresses to avoid frustration.
What is your plan B in case of failure?
Of course, we wish you every success, but it's wise to have a plan B when setting up a business.
How you handle the possibility of things not working out can depend a lot on the kind of relationship you have with your co-founders (like being a close friend, spouse, former colleague, etc.) and each person's individual situation.
Take, for instance, launching a business with your spouse. It may seem like a great plan, but if the business doesn't succeed, you could find yourself losing the entire household income at once, and that could be quite a nerve-wracking situation.
Similarly, starting a business partnership with a friend has its challenges. If the business doesn't work out or if tough decisions need to be made, it could strain the friendship.
It's essential to carefully evaluate your options before starting up to ensure you're well-prepared for any potential outcomes.
Undertake market research for a plumbing company
The next step to start your plumbing company is to use market research to check that there is indeed an opportunity to be seized. Let's take a look at what this involves.
The objectives of market research
In a nutshell, doing market research enables you to verify that there is a business opportunity for your company to seize, and to size the opportunity precisely.
First of all, market research enables you to assess whether the market you're targeting is large enough to withstand the arrival of a new competitor: your plumbing company.
The market analysis will also help you define the product and service offering of your plumbing company, and transcribe it into a market positioning and concept that will strike a chord with your target customers.
Finally, your market research will provide you with the data you need to draw up your sales and marketing plan and estimate the revenue potential of your plumbing company.
Analyse key trends in the industry
Market research for a plumbing company must always begin with a thorough investigation of consumer habits and current industry trends.
Normally, plumbing company market research begins with a sectorial analysis which will provide you with a better understanding of how the industry is organized, who the major players are, and what are the current market trends.

Assess the demand
A demand analysis enables you to accurately assess the expectations of your plumbing company's future customers.
Your analysis will focus on the following questions:
- How many potential customers are present in the geographical areas served by your company?
- What are their expectations and purchasing behaviors?
- How much are they willing to spend?
- Are there different customer segments with distinct characteristics?
- How to communicate and where to promote your business to reach your target market?
The main goal of your demand analysis is to identify potential customer segments that your plumbing company could target and what products or services would meet these customers' expectations.
Supply side
Supply-side analysis looks at the products and services offered by your competitors on the market.
You should focus here on the following questions:
- Who will your competitors be?
- Are they any good?
- Where are they located?
- Who do they target?
- What range of products and services do they offer?
- Are they small independent players?
- What prices do they charge?
- How do they sell their products and services?
- Do their concepts appeal to customers?
One of the aims of your supply-side analysis will be to gather the elements that will enable you to define a market positioning that will set you apart from what is already being done on the market, so as to avoid direct confrontation with competitors already established (more on that below).
Regulations
Market research is also an opportunity to look at the regulations and conditions required to do business.
You should ask yourself the following questions:
- Does it take a specific degree to open a plumbing company?
- Do you need specific licences or business permits?
- What are the main regulations applicable to your future business?
Given that your project is still in its early stages, your analysis of the regulation can be carried out at a high level for the time being. You just want to identify the main laws applicable and check that you meet the conditions for running this type of business before going any further.
Once your project is more advanced, you can come back to the regulation in greater detail with your lawyer.
Concluding your market research
Your market research should lead you to draw a clear conclusion about your chances of commercial success of your business idea:
- Either the market is saturated, and you'd better look into another business idea.
- Or there's an opportunity to be seized in the geographical area you're considering, and you can go ahead with your project to open a plumbing company.
Need a convincing business plan?
The Business Plan Shop makes it easy to create a financial forecast and write a business plan to help convince investors that your business idea can be profitable.

How should I position my plumbing company on the market?
The next step to start your plumbing company is to define precisely the market positioning your company will adopt in order to capitalise on the opportunity identified during your market research.
Market positioning refers to the place your product and service offering occupies in customers' minds and how they differ from the competition. Being perceived as a low-cost solution, for example.
To find a concept and a market positioning that will resonate with your customers, you need to address the following issues:
- How can you differentiate yourself from your competitors?
- Is it better to start or buy a plumbing company already in operation?
- How will you validate your concept and market positioning before investing in the business?
Let's look at these aspects in more detail.
How can you differentiate yourself from your competitors?
Opening a plumbing company means starting with a major disadvantage compared with competitors already active on the market.
While you will have to create everything from scratch, your competitors already have everything in place.
Your competitors' teams know the business well, whereas yours has only just been recruited, their customers are loyal and they benefit from word of mouth that you don't yet have.
So you're going to need a solid plan to succeed in taking market share from your competitors and making your mark.
There are a number of aspects to consider in order to try to avoid direct confrontation if possible:
- Can you target a different customer base than your competitors?
- Can you offer products or services that are different from or complementary to what your competitors already sell?
- How will your competitors react to your plumbing company entering their market?
- Can you build a sustainable competitive advantage that will enable you to compete with your current and future competitors?
Is it better to start or buy a plumbing company already in operation?
The alternative to setting up a new independent business is to buy out and take over a plumbing company already in operation.
A takeover is a good way of reducing the risk of your project compared with a pure start-up.
Taking over a business has two enormous advantages over setting up a new one: you start out on an equal footing with your competitors since you take over the team and the customer base, and you don't increase the supply on the market enabling you to maintain the existing balance on the market where the business operates.
However, the capital requirements for a takeover are higher because the business will have to be bought from its previous owners.
How will you validate your concept and market positioning before investing in the business?
However you decide to set up your business, you will need to ensure that there is a good fit between what you sell and what customers are looking to buy.
To do this, you'll need to meet your target customers to present your products or services and check that they meet their expectations.
Deciding where to base your plumbing company
The next step to opening a plumbing company is deciding where you want to set up your business.
Choosing the right location for your business is like finding the perfect stage for a play. Without it, your business may lack the spotlight it deserves.
Whilst there is no “perfect” location for your plumbing company, one that meets as many of the following factors as possible could be ideal:
- Visibility and foot traffic - This is important for a plumbing company because it can help attract potential customers and increase brand awareness. A location with high visibility and foot traffic can also lead to more walk-in clients.
- Parking space, road and public transport accessibility - A plumbing company requires transportation of equipment and materials, so a location with ample parking space and easy access to main roads is crucial. Public transport accessibility can also make it easier for employees to commute to work.
- Proximity to target customers - Being close to the target market, such as residential areas or commercial buildings, can save time and transportation costs for a plumbing company. It can also help build relationships with repeat customers.
- Competitor presence - While being close to competitors can increase competition, it can also indicate a high demand for plumbing services in the area. This can be a positive factor for a plumbing company looking to establish itself in the market.
This list is obviously not exhaustive and will have to be adapted to the particularities of your project.
Once you’ve considered the factors above, it’s important to think about the budget that your startup has at its disposal. You’ll need to find a location that meets your business requirements but is affordable enough, especially short-term.
If you opt for renting instead of buying your premises, make sure to take into account the terms of the lease, including aspects such as the duration, rent increase, renewal, and so on.
The lease contractual terms vary greatly from country to country, so be sure to check the terms applicable to your situation and have your lease reviewed by your lawyer before signing.

What legal form should I choose for my plumbing company?
The next step to start a plumbing company is to choose the legal form of your business.
The legal form of a business simply means the legal structure it operates under. This structure outlines how the business is set up and defines its legal obligations and responsibilities.
Why is your plumbing company's legal form important?
Choosing the right legal form for your plumbing company is important because this will affect:
- Taxation: your tax obligations depend on the legal structure you choose, and this principle applies to both personal income tax and business taxes.
- Risk exposure: some legal structures have a legal personality (also known as corporate personality) and limited liability, which separates them from the owners running the business. This means that the business would be liable rather than the owners if things were to go wrong (lawsuit, debt owed in case of bankruptcy, etc.).
- Decision-making and governance: how you make key decisions varies based on the legal form of your business. In some cases you might need to have a board of directors and organise general assemblies to enable shareholders to influence major decisions with their voting rights.
- Financing: securing funding from investors requires you to have a company and they will expect limited liability and corporate personality to protect them legally.
- Paperwork and legal formalities: the legal structure you select determines whether certain obligations are necessary, such as producing annual accounts, or getting your books audited.
Popular business legal forms
The specific names of legal structures vary from country to country, but they usually fall within the two main categories below:
- Individual businesses
- Companies
Individual businesses
Individual businesses, like sole traders or sole proprietorships, are made for self-employed entrepreneurs and freelancers rather than businesses which employ staff.
They benefit from straightforward administrative requirements, minimal paperwork to start, simpler tax calculations, and streamlined accounting procedures.
However, the downside is that there's typically no legal distinction between the business and the person responsible for day-to-day operations. This means the owner's personal assets are at risk if the business faces problems or goes bankrupt.
There is also no share capital in such a structure, meaning that individual businesses cannot raise equity from investors which seriously limits funding options.
Companies
Companies are versatile structures suited to projects of all sizes in terms of number of founders, number of employees and amount of capital.
They are a bit more complex to operate than individual businesses with more formalities, stringent accounting requirements, more complex tax implications, etc.
In return, they offer stronger protections to their shareholders. They usually benefit from having their own legal identity and limited liability, meaning co-founders and investors can only ever lose the amount of money they have put into the company.
For instance, if things were to go south (the company files for bankruptcy or there is a legal issue), the company would take the hit, safeguarding the personal assets of the founders and investors.
How should I choose my plumbing company's legal structure?
Deciding on a legal form is easy once you've estimated your sales, decided whether or not you need employees and figured out the number of co-founders joining you.
It's essential to remember that a solid business idea will succeed no matter which legal structure you pick. Tax laws change regularly, so you can't rely on specific tax advantages tied to a particular structure when starting a business.
A proven approach is to look at what legal structures your top competitors are using, and go with the most common option as a working assumption. Once your idea is mature enough, and you're getting closer to officially registering your business, you can get advice from a lawyer and an accountant to confirm your choice.
Can I switch my plumbing company's legal structure if I get it wrong?
Yes, changing your legal structure later is possible, though it may involve selling the old entity to a new entity in some cases, which adds further expenses. If you want to save on such costs, it makes sense to pick the correct legal form for your business the first time around.
Can your business idea be profitable?
Just enter your data and let The Business Plan Shop crunch the numbers. We will tell if your business idea can generate profits and cash flows, and how much you need to get started.

Calculating the budget to open a plumbing company
The next step to opening a plumbing company involves thinking about the equipment and staff needed to launch and run your business on a day-to-day basis.
Each project has its own characteristics, which means that it is not possible to estimate the budget for opening a plumbing company without building a complete financial forecast.
So be careful when you see estimates circulating on the Internet. As with all figures, ask yourself these questions:
- Is my project similar (location, concept, size, etc.)?
- How recent is the information?
- Is it from a trustworthy source?
Startup costs and investments to open a plumbing company
For a plumbing company, the initial working capital requirements and investments may include the following elements:
- Plumbing equipment: This includes items such as pipes, valves, fittings, and fixtures that are necessary for carrying out plumbing services. These are considered fixed assets as they are used repeatedly for the company's operations and have a useful life of more than one year.
- Vehicles: As a plumbing company, you will need to invest in vehicles to transport your equipment and employees to job sites. These vehicles can include vans, trucks, or even specialized plumbing vehicles with built-in equipment. They are considered fixed assets as they are essential for the day-to-day operations of your business.
- Tools and machinery: Plumbing requires a variety of specialized tools and machinery, such as drain snakes, pipe cutters, and welding equipment. These are considered fixed assets as they are essential for providing plumbing services and have a longer useful life than operating supplies.
- Office equipment: As a plumbing company, you will also need to invest in office equipment such as computers, printers, and phones for administrative tasks. These are considered fixed assets as they are used for more than one year and are necessary for the smooth functioning of your business.
- Renovations or upgrades: Depending on the size and growth of your plumbing company, you may need to invest in renovations or upgrades to your office space or warehouse. These are considered fixed assets as they improve the value of your property and have a useful life of more than one year.
Of course, you will need to adapt this list to your company's specific needs.
Staffing plan to operate a plumbing company
To establish an accurate financial forecast for your plumbing company, you will also need to assess your staffing requirements.
The extent to which you need to recruit will of course depend on your ambitions for the company's growth, but you might consider recruiting for the following positions:
Once again, this list is only indicative and will need to be adjusted according to the specifics of your plumbing company.
Other operating expenses required to run a plumbing company
You also need to consider operating expenses to run the business:
- Staff Costs: This includes salaries, wages, and benefits for all of your employees, including plumbers, office staff, and apprentices.
- Accountancy Fees: You will need to hire an accountant or bookkeeper to help you manage your financial records and file your taxes.
- Insurance Costs: As a plumbing company, you will need to have insurance to protect your business, your employees, and your clients from any potential accidents or damages.
- Software Licences: You may need to purchase software licenses for accounting, project management, invoicing, and other business needs.
- Banking Fees: You will incur fees for maintaining a business bank account, processing credit card payments, and other banking services.
- Vehicle Expenses: If you have company vehicles, you will have to pay for gas, maintenance, and insurance for them.
- Advertising and Marketing: To attract new customers, you may need to invest in advertising and marketing efforts, such as creating a website, printing business cards, or running ads.
- Office Rent: If you have a physical office space, you will have to pay rent or a mortgage for it.
- Utilities: You will have to pay for electricity, water, internet, and other necessary utilities to keep your business running.
- Inventory: You will need to purchase plumbing supplies and equipment to complete your jobs, which will incur inventory costs.
- Training and Education: In order to stay up-to-date with industry standards and advancements, you may need to invest in training and education for yourself and your employees.
- Legal Fees: You may need to seek legal advice or services for contract drafting, employee agreements, or other legal matters.
- Taxes: As a business owner, you will need to pay taxes, including income tax, property tax, and sales tax.
- Office Supplies: To keep your office running smoothly, you will need to purchase supplies such as paper, pens, and printer ink.
- Professional Memberships: As a plumbing company, you may need to join professional organizations to network with others in the industry and stay updated with industry news and regulations.
This list will need to be adapted to the specifics of your plumbing company but should be a good starting point for your budget.
Creating a sales & marketing plan for your plumbing company
The next step to start a plumbing company is to think about how you are going to attract and retain customers.
You need to ask yourself the following questions:
- What actions can be leveraged to attract as many customers as possible?
- How will you then retain customers?
- What resources do you need to allocate for each initiative (human and financial)?
- How many sales and what turnover can you expect to generate in return?
How you will attract and retain customers depends on your ambition, the size of your startup and the nature of your exact concept, but you could consider the following initiatives.
Your sales forecast may also be influenced by seasonality related to your business type, such as fluctuations during busy holiday periods, and your competitive environment.

Build your plumbing company's financial forecast
The next step to start your plumbing company: putting your financial projections together.
What is the financial forecast for a plumbing company?
A forecast is a quantified decision-making document that shows the initial investment required to open a plumbing company and the company's potential profitability and cash flow generation over the next 3 to 5 years.
As you think about your plumbing company idea, the main role of financial projections will be to help you decide whether it makes sense to create the company.
Building a financial forecast helps determine the amount of initial financing required to start your plumbing company.
In fact, creating financial projections is the only way to assess the amount of initial financing you'll need to open your plumbing company, and to make sure your project makes economic and financial sense.
Keep in mind that very few business ideas are financially viable. At The Business Plan Shop, we've seen nearly a million business start-up ideas, and we estimate that less than one in four is economically viable.
Your forecast will therefore require your full attention and constant revision, as your project matures. It's also a good idea to simulate different scenarios to anticipate several possibilities (what happens if your sales take longer than expected to ramp up, for example), so you're ready for all eventualities.

When seeking financing, your forecast will be incorporated into your business plan, which is the document you will use to present your business idea to financial partners. We'll come back to the business plan in more detail later in this guide.
Creating and updating your plumbing company's forecast is an ongoing process. Indeed, having up-to-date financial projections is the only way to maintain visibility over your company's future cash flow and cash position.
Forecasting is, therefore, the financial management tool that will be with you throughout the life of your company. Once you've started trading, you'll need to regularly compare the difference between your actual accounts and your forecasts, and then adjust them to maintain visibility over your future cash flows.
What does a financial projection look like?
Your plumbing company forecast will be presented using the following financial tables.
The projected P&L statement
The projected P&L statement for a plumbing company shows how much revenue and profits your business is expected to generate in the future.

The projected balance sheet of your plumbing company
Your plumbing company's projected balance sheet provides a snapshot of your business’s financial position at year-end.

The cash flow forecast
A projected cash flow statement for a plumbing company is used to show how much cash the business is expected to consume or generate in the years to come.

Which solution should you use to make a financial projection for your plumbing company?
Using an online financial forecasting tool, such as the one we offer at The Business Plan Shop, is the simplest and safest solution for forecasting your plumbing company.
There are several advantages to using specialised software:
- You can easily create your financial forecast by letting the software take care of the financial calculations for you without errors
- You have access to complete financial forecast templates
- You get a complete financial forecast ready to be sent to your bank or investors
- The software helps you identify and correct any inconsistencies in your figures
- You can create scenarios to stress-test your forecast's main assumptions to stress-test the robustness of your business model
- After you start trading, you can easily track your actual financial performance against your financial forecast, and recalibrate your forecast to maintain visibility on your future cash flows
- You have a friendly support team on standby to assist you when you are stuck

Finding a name and registering your plumbing company
The next step in starting a plumbing company is to decide on a name for your entity.
For starters, you cannot take a name similar to a name already registered by a competitor or protected by a trademark without inevitably risking getting sued. So you’ll need to find a name available, and reserve it before others can.
In addition, you will probably want to use the same name for:
- Your company’s legal name - Example LTD or Example Inc
- Your trading name - Example
- A trademark - Example ®
- Your company’s domain name - Example.com
The issue is that you’ll need to register your name in three different places almost simultaneously, but with each place having its own timeframes:
- Registering a domain name is instantaneous
- Registering a trademark takes at least 3 months (if your application is accepted)
- Registering a company depends on the country, but it's generally fairly quick
You will therefore be faced with the choice of either registering everything at once in the hope that your name will be accepted everywhere, or proceeding step by step in order to minimise costs, but taking the risk that someone else will register one of the names you wanted in the meantime.
Our advice is to discuss the strategy with your legal counsel (see further down in this guide) and to give priority to your domain names and your registered trademark. You'll always have the option of using a trading name that's different from your company's legal name, and that's not a big deal.
To check that the name you want is not already in use, you should consult:
- Your country's business register
- The register of trademarks where you wish to obtain protection
- Your preferred search engine
- A domain name reservation company (such as GoDaddy)
If the name you want is available, you can go ahead and register it.

Develop your plumbing company's corporate identity
The next step to launching a plumbing company: defining your company's visual identity.
Your corporate identity defines how your company's values are communicated visually. It makes you unique and allows you to stand out visually from your competitors and be recognized by your customers.
Defining your corporate identity can easily be done by you and your co-founders, using the many free tools available to generate color palettes, logos and other graphic elements. Nevertheless, this task is often best entrusted to a designer or agency to achieve a professional result.
Your plumbing company's visual identity will include the following elements:
- Logo
- Brand guidelines
- Business cards
- Website theme
Logo
The goal is to have stakeholders identify your business logo quickly and relate to it. Your logo will be used for media purposes (website, social networks, business cards, etc.) and legal documents (invoices, contracts, etc.).
The design of your logo must be emblematic, but it's also important that it can be seen on any type of support. To achieve this, it should be easily available in a range of colors, so that it stands out on both light and dark backgrounds.
Brand guidelines
The brand guidelines of your plumbing company act as a safeguard to ensure that your image is consistent whatever the medium used.
Brand guidelines lay out the details like the typography and colors to use to represent your company.
Typography refers to the fonts used (family and size). For example, Arial in size 26 for your titles and Tahoma in size 15 for your texts.
When it comes to the colors representing your brand, it's generally a good idea to stick to five or fewer:
- The main colour,
- A secondary colour (the accent),
- A dark background colour (blue or black),
- A grey background colour (to vary from white),
- Possibly another secondary colour.
Business cards
A rare paper medium that continues to survive digitalization, business cards are still a must-have for communicating your plumbing company contact details to your customers, suppliers and other partners.
In principle, they will include your logo and the brand guidelines we mentioned above.
Website theme
Likewise, the theme of your plumbing company website will include your logo and follow the brand guidelines we discussed earlier.
This will also define the look and feel of the main visual elements on your website:
- Buttons
- Menus
- Forms
- Banners
- Etc.
Understanding the legal and regulatory steps involved in opening a plumbing company
The next step in opening a plumbing company is to take the necessary legal and regulatory steps.
We recommend that you be accompanied by a law firm for all of the steps outlined below.
Registering a trademark and protecting the intellectual property of your plumbing company
The first step is to protect your company's intellectual property.
As mentioned earlier in this guide, you have the option to register a trademark. Your lawyer can assist you with a thorough search to ensure your chosen trademark is unique and doesn't conflict with existing ones and help select the classes (economic activities) and jurisdictions in which to register your trademark.
Your lawyer will also be able to advise you on other steps you could take to protect your company's other intellectual property assets.
Drafting the contractual documents for your plumbing company
Your plumbing company will rely on a set of contracts and legal documents for day-to-day operations.
Once again, we strongly recommend that you have these documents drawn up by a lawyer.
Your exact needs will depend on the country in which you are launching your plumbing company and the size of the company you are planning.
However, you may wish to consider the following documents at a minimum:
- Employment contracts
- General terms and conditions of sale
- General terms and conditions of use for your website
- Privacy Policy for your website
- Cookie Policy for your website
- Invoices
- Etc.
Applying for licences and permits and registering for various taxes
The licenses and permits needed for your business will depend on the country where you are establishing it. Your lawyer can guide you on the regulations relevant to your activity.
Similarly, your chartered accountant will be able to help you register for taxes and take the necessary steps to comply with the tax authorities.
Need a convincing business plan?
The Business Plan Shop makes it easy to create a financial forecast and write a business plan to help convince investors that your business idea can be profitable.

How do I write a business plan for a plumbing company?
Once you've completed all the above steps, you can start writing the business plan for your plumbing company.
What is a plumbing company's business plan?
The business plan is a document containing:
- The financial forecast (discussed earlier in this guide), highlighting the project's financing requirements and profitability potential,
- A written presentation, which presents your project in detail and provides the necessary context for the reader to assess the relevance and coherence of your forecast.
The business plan is particularly important: it will help you validate your business idea and ensure its coherence and financial viability.
But it's also the document you'll send to your bank and potential investors to present your plan to open a plumbing company and make them want to support you.
So it's best to draw up a professional, reliable and error-free business plan.
How to write a business plan for my plumbing company?
If you're not used to writing business plans, or if you want to save time, a good solution is to use an online business plan software for startups like the one we offer at The Business Plan Shop.

Financing the launch of your plumbing company
Once your business plan has been written, you’ll need to think about how you might secure the funding required to open your plumbing company.
The amount of initial financing required will of course depend on the size of your plumbing company and the country in which you wish to set up.
Financing your startup will probably require you to obtain a combination of equity and debt, which are the primary financial resources available to businesses.
Equity funding
Equity refers to the amount of money invested in your plumbing company by founders and investors and is key to starting a business.
Equity provides your company with stable, long-term (often permanent) capital. It also demonstrates the commitment of the company's owners to the project, since these sums can be lost in the event of bankruptcy.
Because the equity invested by the founders may be lost if the project doesn't succeed, it signals to investors and other financial institutions the founders' strong belief in the business's chances of success and might improve the likelihood of obtaining further funding as a result.
In terms of return on investment, equity investors receive dividends paid by the company (provided it is profitable) or realise capital gains by reselling their shares (provided they find a buyer interested in the company).
Equity investors are, therefore, in a very risky position. They stand to lose their initial investment in the case of bankruptcy and will only obtain a return on investment if the business manages to be profitable or sold. On the other hand, they could generate a very high return if the venture is a financial success.
Given their position, equity investors are usually looking to invest in business ventures with sufficient growth and profitability potential to offset their risk.
From the point of view of the company and its creditors, equity reduces risk, since equity providers finance the company and are only remunerated in the event of success.
From a technical standpoint, equity consists of:
- Share capital and premiums: which represent the amount invested by the shareholders. This capital is considered permanent as it is non-refundable. In return for their investment, shareholders receive shares that entitle them to information, decision-making power (voting in general assembly), and the potential to receive a portion of any dividends distributed by the company.
- Director loans: these are examples of non-permanent capital advanced to the company by the shareholders. This is a more flexible way of injecting some liquidity into your company than doing so as you can repay director loans at any time.
- Reserves: these represent the share of profits set aside to strengthen the company's equity. Allocating a percentage of your profits to the reserves can be mandatory in certain cases (legal or statutory requirement depending on the legal form of your company). Once allocated in reserves, these profits can no longer be distributed as dividends.
- Investment grants: these represent any non-refundable amounts received by the company to help it invest in long-term assets.
- Other equity: which includes the equity items which don't fit in the other categories. Mostly convertible or derivative instruments. For a small business, it is likely that you won't have any other equity items.
The main sources of equity are as follows:
- Personal contribution from the founders' savings.
- Private investors: business angels, friends and family.
- Crowdfunding campaigns to find investors or collect donations (usually in exchange for a gift).
- Government initiatives such as loans on favourable terms to help partners build up their start-up capital.
Debt funding
Another option for partially funding your plumbing company is to borrow.
By definition, debt works in the opposite way to equity:
- Debt needs to be repaid, whereas equity is permanent.
- Lenders get a contractually guaranteed return, whereas equity investors only generate a return if the company is a success.
When a company borrows money, it agrees to pay interest and repay the borrowed principal according to a pre-established schedule. Therefore, lenders make money regardless of whether the company is profitable and their main risk is if the company goes bankrupt.
To limit their risk, lenders are usually conservative and cautious in their approach. They only finance projects where they are confident that they will be repaid in full.
Companies borrow in two ways:
- Against their assets: this is the most common way of borrowing. The bank finances a percentage of the price of an asset (a vehicle or a building, for example) and takes the asset as collateral. If the company cannot repay, the bank seizes the asset and sells it to limit its losses.
- Against their future cash flows: the bank evaluates the company's financial forecast to estimate its borrowing capacity and assesses the conditions (amount, interest rate, term, etc.) on which it is prepared to lend, taking into account the credit risk posed by the company.
It's difficult to borrow against future cash flow when setting up a plumbing company, because the business doesn't yet have historical data to reassure lenders about the credibility of the forecasted cash flows.
Borrowing against assets is, therefore, often the only option available to entrepreneurs. What's more, the assets that can be financed with this option must be easy to resell, in the unfortunate event that the bank is forced to seize them, which may limit your options even further.
In terms of possible sources of borrowing, the main sources here are banks and credit institutions. Bear in mind, however, that each institution is different, both in terms of the risk it is prepared to accept and in terms of how the risk of your project will be perceived and what items it will agree to finance.
In some countries, it is also possible to borrow from private investors (directly or via crowdlending platforms) or other companies, but not everywhere.
Things to remember about financing a plumbing company
There are various ways you can raise the initial financing you need to open your plumbing company. A minimum amount of equity will be needed to give the project credibility, and bank financing can be sought to complete the package.
Launching your plumbing company and monitoring progress against your forecast
Once you’ve secured financing, you will finally be ready to launch your plumbing company. Congratulations!
Celebrate the launch of your business and acknowledge the hard work that brought you here, but remember, this is where the real work begins.
As you know, 50% of business start-ups do not pass the five-year mark. Your priority will be to do everything to secure your business's future.
To do this, it is key to keep an eye on your business plan to ensure that you are on track to achieve your goals.
No one can predict the future with certainty, so it’s likely that your plumbing company's financial performance will differ from what you predicted in your forecast.
This is why it is recommended to make several forecasts:
- A base case (most likely)
- An optimistic scenario
- And a pessimistic scenario to test the robustness of your financial model
If you follow this approach, your numbers will hopefully be better than your optimistic case and you can consider accelerating your expansion plans. That’s what we wish you anyway!
If, unfortunately, your figures are below your base case (or worse than your pessimistic case), you will need to quickly put in place corrective actions, or consider stopping the activity.
The key, in terms of decision-making, is to regularly compare your real accounting data to your plumbing company's forecast to:
- Measure the discrepancies and promptly identify where the variances with your base case come from
- Adjust your financial forecast as the year progresses to maintain visibility on future cash flow and cash position
There is nothing worse than waiting for your accountant to prepare your year-end accounts, which can take several months after the end of your financial year (up to nine months in the UK for example), to realise that the performance over the past year was well below the your base case and that your plumbing company will not have enough cash to keep running over the next twelve months.
This is why using a financial forecasting solution that integrates with accounting software and offers actuals vs. forecast tracking out of the box, like the financial dashboards we offer at The Business Plan Shop, greatly facilitates the task and significantly reduces the risk associated with starting a business.
