Plumbing Business Valuations
Independent valuations for plumbing businesses across Australia.
Green Standard values residential, commercial, maintenance, construction and specialist plumbing businesses. Two plumbing businesses with the same profit can be worth very different amounts, and the difference is usually found in where the work comes from and who does it.
A service business with strata, real estate and commercial maintenance accounts, a booked-out team of licensed plumbers and a phone number that rings regardless of who owns it is a different asset from a construction subcontractor that relies on two builders and an owner who quotes, supervises and works on the tools every day.
We examine the revenue mix, the licences, the people, the customers and the fleet, then form a view on the earnings a new owner could reasonably expect to keep.
How much is a plumbing business worth?
A plumbing business is worth what its maintainable earnings support once a market wage has been paid for the owner’s own work, adjusted for how much of those earnings would continue under a new owner. Service and maintenance work with documented customers carries less risk than builder-dependent construction work, so the same profit can be worth quite different amounts. The worked example below shows each step with illustrative figures.
Plumbing businesses we value
What affects the value of a plumbing business?
These are the questions we work through when we value a plumbing business. Some raise value, some reduce it, and most matter only in combination with the others.
Revenue quality
Recurring maintenance revenue
Work from strata managers, property managers, commercial sites and councils tends to repeat year after year. We look at how long each account has been held, whether it is documented, and whether it would pass to a new owner.
Emergency and service work
Reactive work often carries the best margins, but it depends on the business being found and answering the phone. We check whether enquiries come to the business brand, website and number, or to the owner personally.
Construction and project revenue
Builder and project work is lumpier. Fixed-price tenders, progress claims, retentions and materials price movements all affect how reliable the earnings are, so construction revenue is usually weighed differently from service revenue.
Gross margin by service type
A blended margin hides a lot. We separate service, maintenance and construction margins where the records allow, because a buyer will price each stream differently.
Regulated recurring work
Annual backflow prevention testing and similar compliance work recurs because the device owner is required to have it done. A well kept testing register can be one of the most transferable assets in the business.
People and licences
Owner billable hours
If the owner works on the tools, quotes the jobs and handles the key accounts, a new owner has to pay someone to do all of that. We deduct a market cost for the owner’s role before any multiple is considered.
Licence dependency
Plumbing work must be carried out or supervised by appropriately licensed people, and gasfitting, drainage and backflow testing can each need separate licences or endorsements. Where the owner holds the only relevant licence, continuity is a real question for any buyer.
Employee plumbers and apprentices
A stable team of licensed plumbers is hard to build and expensive to replace. We look at tenure, licence classes and wages, and at the apprentice pipeline, which matters more than it used to in a tight labour market.
Subcontractor usage
Subcontractors give flexibility but less control over quality, availability and customer relationships. We consider how much work depends on them and whether the arrangements would continue.
Customers and relationships
Customer concentration
A business that earns a third of its revenue from one customer carries a risk that the profit and loss statement does not show. We measure it over several years, not one.
Builder relationships
Builder work is often won through a personal relationship with a site supervisor or director. We consider how many builders the business works for, the payment history, and exposure to a builder’s financial failure.
Commercial contracts
We read the terms: length remaining, renewal history, schedules of rates, panel arrangements, and any clause that lets the customer terminate on a change of ownership.
Reputation and referral sources
Reviews, repeat customers, referral partners and search visibility all bring work in. We look at which of them belong to the business and would carry across to a new owner.
Assets and operations
Fleet and equipment
Fitted-out vans, drain cameras, jetters, relining equipment and excavators are needed to earn the profits. We consider their condition, any finance owing, and what it costs to keep the fleet current.
Geographic coverage
Travel time is unbilled time. A dense service area with short drives between jobs supports better utilisation than a wide area served from a single depot.
Systems and scheduling
Job management software, dispatch, price books and job history make a business easier to run without its founder. They also give a valuer evidence that is otherwise hard to get.
Ability to operate without the owner
The question that sits behind most of the others: if the owner stepped away for three months, would the work still come in, be done well and be invoiced? The answer shapes both the earnings we adopt and the risk we apply to them.
How a buyer reads a plumbing business
Buyers of plumbing businesses include established plumbing groups expanding into a new area, facilities maintenance companies adding a trade, and individuals buying their way into ownership. They are all asking the same question in different ways: how much of this profit will still be here once the current owner has gone?
Maintenance and service businesses with documented accounts, licensed staff and a brand that generates its own enquiries tend to attract the widest interest. Construction-heavy businesses that depend on a small number of builders, or on the owner’s own licence and relationships, are usually priced more cautiously, even when their recent profits are higher.
A valuation works through the same questions, but independently and with the reasoning written down.
Adjustments we often make in plumbing businesses
Reported profit is restated to what the business earns on a commercial footing before any method is applied. Every adjustment is listed in the report.
Owner wages
Replacing drawings, or a salary set for tax reasons, with a market cost for the work the owner actually does.
Family members on payroll
Wages paid above or below market rate, or for roles that a buyer would not need.
Vehicles used privately
Private use of business vehicles, and private vehicles run through the business.
Related-party premises
A workshop or yard owned by the owner’s family trust or super fund and rented at other than market rent.
One-off projects
A single large commercial job, or a builder relationship that has ended, that would distort maintainable revenue.
Temporary subsidies and incentives
Government apprentice wage subsidies or other support that will not recur.
Bad debts and defect costs
Unusual losses from a builder insolvency or a one-off rectification claim, separated from the normal cost of doing the work.

Plumbing valuations: common questions
How much is a plumbing business worth?
A plumbing business is generally worth what its maintainable earnings support after a market wage is paid for the owner’s own work, adjusted for how much of those earnings would continue under a new owner. Recurring maintenance work, licensed staff and a spread of customers support a higher value; dependence on the owner or on one or two builders reduces it. Our guide on how much a plumbing business is worth works through an example.
Does it matter that I am the only licensed plumber in the business?
Yes. If the business can only operate under your licence, a buyer needs to hold the licence themselves or employ someone who does, and they will weigh that cost and risk. It does not make the business unsaleable, but it is one of the clearest examples of value that sits with the owner rather than the business.
Are my vans and equipment valued on top of the business?
Usually not. Where the business is valued on its earnings, the vans and equipment needed to produce those earnings are part of that value rather than an addition to it. Assets the business does not need, and finance owing on the fleet, are dealt with separately. Our guide on whether equipment adds to business value explains the distinction.
Most of our work is new homes for two builders. Can it still be valued?
Yes. Builder concentration is common in plumbing and does not prevent a valuation. The report looks at the length and history of the relationships, payment terms, the builders’ own pipelines, and what would happen to revenue if one relationship ended.
