How a Melbourne Trade Contracting Business Is Valued

Electrical, plumbing, air conditioning and fire services contractors, where a book of scheduled compliance work is worth far more than the same profit earned job by job.

A trade contracting business in Melbourne is valued by capitalising the earnings that remain after the owner is paid a market wage for the trade work and the management they do. Recurring maintenance and essential safety measures contracts attract a much lower risk loading than project work, and the vehicles, plant and tools net of finance set the floor.

Why Melbourne trade contractors ask what the business is worth

The usual reasons are a sale to a competitor or a larger facilities group, a succession to a foreman or a family member, a family law settlement, a partner leaving, a bank asking for a figure behind a vehicle facility, or an ATO market value requirement when the business moves from a sole trader into a company or trust.

The most useful result is often the diagnosis rather than the number. A plumbing business in Werribee can be very profitable while the owner is on the tools and worth little more than its vans and stock once they stop. The valuation shows how much of the value sits in transferable maintenance contracts and a licensed team, and how much sits in the owner's own labour and personal registration.

Why the income approach leads for a trades business

The Income Approach leads. Scheduled maintenance and compliance work produce earnings that recur without being re-won, which is exactly the situation the income approach is designed for.

The method is capitalisation of future maintainable earnings. We establish what the business sustainably earns once the owner is paid a market wage for the hours on the tools and for running the business, then divide that figure by a capitalisation rate built from a risk-free base and a series of premiums for size, industry and the particular business.

Almost all of the company-specific premium depends on the work mix. A contractor holding essential safety measures, scheduled servicing or facilities contracts across a portfolio of Docklands and Southbank office towers has revenue it can forecast, so the loading is low. A contractor winning fit-out projects one tender at a time has to start every year from zero, so the loading is high even where last year's profit was identical.

Market cross-check

Sales of trades businesses of comparable size, discipline and work mix are used to test the range. There is evidence, but less of it than in retail-facing sectors, so it shapes the conclusion rather than dictating it.

Asset cross-check

Vans, plant, tools and stock at market value, less the finance secured on them. This is the floor, and where the owner is the business and little work is contracted it can be close to the whole answer.

Adjustments that move the number for a trade contractor

Most disputes about a valuation begin with the adjustments, so every one is listed in the report with the reason for it. For a trade contracting business the items that come up again and again are:

Trade contracting across Melbourne

Trades businesses in Melbourne follow the building. The growth corridors in Wyndham, Casey and Hume, where Werribee, Cranbourne and Craigieburn keep adding housing estates, support a large population of electrical, plumbing and air conditioning contractors working for volume builders. The south-east, from Dandenong through to Pakenham, adds the industrial and commercial work, while the CBD, Docklands and Southbank towers generate the compliance and maintenance contracts that hold their value best.

Regulation shapes who can buy the business. Builders and plumbers are registered with the Victorian Building Authority, electricians are licensed by Energy Safe Victoria, and domestic work is governed by the Domestic Building Contracts Act 1995 (Vic). Where the registration or licence sits with the owner personally, a buyer must bring their own licensed person, which narrows the market and is reflected in the rate. A business whose team holds its own licences, and whose electrical contractor registration sits with the company rather than the departing owner, is far easier to transfer, and the comparable set is drawn accordingly.

The sector keeps adding entrants. Construction, the ABS division that trade contracting sits within, grew 3.4 per cent in the national count of businesses in 2025 to 2026 (Source: ABS, Counts of Australian Businesses, July 2022 to June 2026, released 18 August 2026), and Victoria recorded a net increase of 19,581 actively trading businesses across all industries in the same year (same source). Easy entry keeps rates under pressure on project work, which is one more reason a contracted compliance book is valued so differently from a tender-by-tender one.

What the report sets out, and how it holds up under review

The report begins by stating what the valuation is for, the standard of value, the valuation date and the information we relied on, including anything we asked for and did not receive. It then sets out each approach considered, the method chosen under it, every adjustment and the reason for it, and reconciles the results into a range with the weighting explained in words.

That explanation is what carries the opinion through review. A conclusion that cannot say why the income result was preferred, or why one point in the range was selected over another, will not survive cross-examination in the County Court of Victoria or a review by an opposing expert. Reports are prepared consistently with APESB, APES 225 Valuation Services and are signed by a credentialed certified valuer who is ready to explain and defend the opinion.

Which report a trades business needs

An Indicative valuation suits an owner trying to work out whether they have a saleable business or a well-paid job. It is for internal decision-making and is not written for third party reliance. A Summary report fits a sale, a partner buy-out or a finance application. A Detailed report is required for family law, a shareholder or partnership dispute, and any matter where another expert will review the opinion.

Depth follows purpose. The more likely the report is to be read by a court, a lender, the ATO or another expert, the more of the reasoning has to be on the page.

Indicative

For internal decision-making. Useful for testing an offer, setting an expectation before a negotiation, or deciding whether to go to market. It is not written for third party reliance.

Summary

Sets out the approaches applied, the normalisation adjustments made and the reasoning behind the conclusion. The usual choice for a sale, an ownership change or a finance application.

Detailed

Applies and reconciles all relevant approaches in full. The level required where a court, the ATO, a lender or another expert will review the opinion.

Questions Melbourne trade contractors ask

By capitalising future maintainable earnings. We first pay the owner a market wage for both the hours on the tools and the management of the business, then apply a capitalisation rate that reflects how much of the revenue is contracted maintenance or compliance work and how much is project work won tender by tender. Vehicles, plant and tools at market value, less finance, set the minimum value.
Because the revenue returns without being re-won. Scheduled servicing and essential safety measures obligations attach to the building rather than to the economic cycle, so a buyer can forecast them with some confidence. Project revenue has to be rebuilt every year, so it attracts a much higher risk loading even when the profit figure is the same.
Often much less than the owner expects. Once a market wage for the trade work is deducted, what remains is the true return on the business itself. If little remains, the value sits close to the net worth of the vans, plant and stock, and the report will say plainly that the owner has a job rather than a business a buyer will pay for.
Subcontractor costs are normalised to commercial rates and the classification of each arrangement is examined. Where subcontractors look like employees, the business carries payroll tax and entitlement exposure that a buyer will price or exclude. An unresolved position is treated as a risk loading and, where it can be quantified, as a contingent liability.
Not by themselves. Registration with the Victorian Building Authority and an electrician's licence from Energy Safe Victoria belong to the person who holds them, so a buyer must either hold the equivalent or employ someone who does. That narrows the pool of buyers and lowers the value. A business with licensed tradespeople on staff and its electrical contractor registration held by the company is materially easier to sell.
Certified reports are delivered from seven business days once the information is in. Three years of financial statements, a job list that separates contracted maintenance from project work, the subcontractor agreements, vehicle and plant registers with their finance schedules and the yard lease are the items that usually set the pace.
