The short answer
A workshop is priced as a multiple of its normalised earnings, meaning profit after a market wage has been charged for whoever runs it, with parts stock and work in progress settled separately at value. The multiple depends on which kind of workshop it is far more than on the trade. A mechanical workshop sells on its repeat customer book and the technicians who turn hours into revenue. A smash repairer sells on its insurer work, which sits in agreements the owner does not control and which, historically, have not reliably passed to a buyer. For smash repairers there is one published broker range worth citing, with caveats. One Australian business broker's 2026 M&A overview of the sector puts independent single-site operators without insurer panel relationships (EBITDA under $500,000, often priced on assets) at 2.0 to 3.5 times EBITDA, single-site businesses holding insurer preferred repairer status (EBITDA of $500,000 to $1.5 million) at 3.0 to 5.0 times, and multi-site portfolios with that status at 4.0 to 6.0 times. The broker describes these as observed and estimated ranges and does not publish the sales behind them, so treat them as one broker's map of the terrain, not a price for any particular business. For mechanical workshops we have not found a published range of completed sale prices that meets our standard, so we do not quote one. Broker listings show asking prices and seller-stated profit, which are not what a buyer paid, and they do not consistently say whether a wage for the owner has been deducted.
What a buyer is really paying for
A workshop sells capacity: technician hours, bay time and the flow of vehicles that fills them. Goodwill is the expectation that the flow continues after the owner leaves. The market value standard (a willing but not anxious buyer and seller, from Spencer v Commonwealth (1907) and reflected in the ATO's "Market valuation for tax purposes" guidance) asks what a knowledgeable buyer would pay, and a knowledgeable workshop buyer asks one question first: if the owner is not here on the Monday after settlement, which revenue stays? The answer differs by model. A general mechanical workshop with a long customer list has earnings that are spread thin and repeat naturally. One leaning on a few fleet accounts has a concentration problem. An independent smash repairer working for private customers has to win each job. A smash repairer on insurer networks has steady volume, set by someone else, at prices set by someone else. A multi-site group adds management depth and a wider pool of buyers.
The insurer agreement: the asset that may not transfer
Many smash repairers earn a large share of their revenue under agreements with insurers, usually called preferred or approved repairer agreements, through which the insurer directs claimants to the repairer. The repairer owns the premises, booth and staff, while the insurer controls the volume, the price list and the right to keep sending work. The best public evidence is old but direct. The Productivity Commission's 2005 inquiry, Smash Repair and Insurance, found that tenure of preferred status is not secure, contracts appear detailed and somewhat intrusive, and status is generally non-assignable and so lost if the business is sold. It recorded one insurer offering an incoming owner a three-month trial while others usually cancelled status, and recommended that status not end automatically on sale, with a six-month trial. Those are 2005 findings and terms have changed since, so the current agreement and the insurer's written position govern. But the 2026 broker report cited above still calls insurer panel status the most consequential valuation driver and lists transferable panel agreements among the factors that lift a business within its range. Until the insurer confirms in writing what happens on a sale, the insurer earnings have to be shown on two footings, carried across and not, and the price range is the distance between them. The evidence asked for:
- ·Every insurer agreement in full, including term, termination, assignment and change-of-ownership clauses and performance targets
- ·Revenue by insurer, fleet and private customer for three years, showing concentration and its trend
- ·Insurer scorecards, notices of review, agreed labour, paint and parts pricing and how it has moved
- ·Weekly vehicle throughput, average repair value and cycle time
- ·The insurer's written position on a sale, including any trial period offered to an incoming owner
Mechanical workshops: the customer book and technician hours
A mechanical workshop is a repeat-visit business: logbook services, brakes, tyres, air-conditioning and pre-registration checks bring the same customers back on a cycle. The buyer is paying for the share of next year's invoices that will come from customers already on file, and whether they return to a new owner. An account worth a large share of revenue, such as a fleet, is a customer contract rather than goodwill, and buyers discount it. Revenue is hours sold at the labour rate plus parts margin, so the constraint is often technicians, not bays. Motor mechanics and panel beaters are both on the Commonwealth's Core Skills Occupation List released in December 2024, and the same broker report says older owner-operators cite labour scarcity and technology complexity as primary reasons for selling. A technician customers know can take customers with them when they leave, particularly in regional markets. If the owner is the senior diagnostician or the face at the counter, part of the profit is personal goodwill and the normalised figure must charge a market wage for that job. The evidence that does the work:
- ·Invoice-level data for three years: customers, vehicles, repeat rate and average invoice value
- ·A customer list split into private, fleet and trade, with revenue per account and forward bookings
- ·The technician roster: qualifications, tenure, pay, hours sold against hours paid, and who holds the tradesperson certificates
- ·Parts stock with ageing, and work in progress at the cut-off date
- ·The owner's actual weekly hours and duties, described task by task
Equipment, electric vehicles and driver assistance
A mechanical workshop needs hoists, alignment, diagnostic, air-conditioning and tyre equipment and current scan tools. A smash repairer adds spray booths, measuring and frame systems and calibration equipment for driver assistance systems. A buyer prices any catch-up spending that is due as a deduction from the price, whatever the depreciation schedule says, because written-down value in the accounts is largely a tax artefact. The Motor Trades Association of Australia reported that battery electric vehicles were a record 19.9 per cent of new vehicle sales in May 2026, but new sales are not the fleet on the road, so the workload shifts gradually. Australian Standard AS 5732:2022 sets out workshop layout, tools and protective equipment for EV maintenance and repair, and trade press reports that Victoria has brought in EV inspection requirements linked to it. The Motor Vehicle Service and Repair Information Sharing Scheme under the Competition and Consumer Act 2010, in force since 1 July 2022, requires manufacturers to make diagnostic, service and repair information available to independent repairers at no more than fair market value, which lowers the information barrier but not the cost of tools and training. The same broker report quotes 4.5 to 7.0 times EBITDA for prestige, EV or driver-assistance certified repairers, which are specialist businesses, and an ordinary workshop should not assume that range.
State licensing, the lease and the other standing deductions
Licensing differs by state. In New South Wales, the Motor Dealers and Repairers Act 2013 requires the owner of a motor vehicle repair business to hold a repairer licence, and anyone carrying out repair work to hold a tradesperson certificate. In Western Australia, the Motor Vehicle Repairers Act 2003 requires repair businesses to be licensed and repairers who work unsupervised, or supervise others, to hold a repairer's certificate. Victoria has no single general repairer licence, but specific approvals apply, such as licensed vehicle tester status for roadworthiness certificates. Trade press reports that several state governments are considering separate licensing for EV repair. Where a licence is required, it attaches to whoever owns and operates the business, so a buyer must hold or obtain the licence in their own right, and how a change of owner is handled is a question for the regulator and a condition of settlement. If the owner holds the only tradesperson certificate, no certificate holder is left on the floor after exit. The lease is the next document after the financial statements. Tenure and options should match the period the earnings assumption runs for, and where the premises sit in a family trust or related entity, the rent charged needs testing against market rent, because a below-market rent flatters earnings the new owner will not receive. Site obligations such as trade waste arrangements, planning permissions and the condition of the land after years of fuel, oil and solvents, and warranty and re-repair obligations on completed work, are contingent liabilities behind the goodwill.
A worked example: one contract question, two very different prices
Consider a hypothetical single-site smash repairer with revenue of $4,000,000, where two insurers supply about 70 per cent of its vehicles. Reported EBITDA is $700,000, but the owner manages the workshop and draws distributions, not a wage. A market salary for a workshop manager is $140,000 including superannuation, so the figure falls by that amount. The owner's family trust owns the premises and charges $120,000 a year against a market rent of $180,000, which takes off another $60,000. Documented personal expenses of $25,000 are added back. Normalised EBITDA is $700,000 less $140,000 less $60,000 plus $25,000, which is $525,000. If the two main insurers confirm in writing that their agreements continue with the buyer, use an assumed multiple for illustration of 3.0 to 4.0 times, the lower half of the published single-site range for insurer-status businesses, because two insurers supply most of the work. That gives $1,575,000 to $2,100,000. If the agreements do not carry across and a buyer models an independent business, once most referred work has gone and labour has been cut to suit, maintainable EBITDA might be $300,000. At an assumed multiple for illustration of 2.0 to 3.0 times, inside the published range for independents, that gives $600,000 to $900,000. In both cases the buyer deducts $120,000 of deferred capital spending, for a spray booth due for replacement and new calibration equipment. The supportable range is then $1,455,000 to $1,980,000 if the agreements carry across and $480,000 to $780,000 if they do not. Every figure is illustrative, not a benchmark. The point is that one contractual question, not the quality of the workshop, moves the midpoint of the range by more than $1 million.
What a defensible workshop valuation file contains
The conclusion is a supportable range with the most supportable position concluded within it, and the file behind it typically contains:
- ·Three to five years of financial statements plus year-to-date trading, reconciled to the workshop management system and the bank
- ·A normalisation schedule with evidence for each adjustment: the owner's market wage, related-party rent against market rent, and personal expenses
- ·Invoice-level customer analysis showing repeat rate, concentration and the split between private, fleet and insurer work
- ·For a smash repairer, every insurer agreement with its change-of-ownership clauses, revenue by insurer and the insurer's written position on a sale
- ·The technician roster, an equipment register with the timing and cost of the next replacement, and the licences and approvals held
- ·The lease in full, the site obligations, and sensitivity analysis across the supportable range, using completed transactions where they exist and not asking prices
When the number has consequences
A formal valuation becomes worth commissioning when someone else has to test the number: a sale where a buyer will run diligence on your customer records or insurer agreements, a buy-out between workshop owners, a family law property settlement, or a CGT event, including small business CGT concession claims under Division 152 of the Income Tax Assessment Act 1997, where eligibility can turn on documented market values and on the $6 million maximum net asset value test. An owner who wants a report written to a predetermined number will not get one from Oliver Group. Oliver Group prepares independent valuations only. It is not a tax agent and does not give tax, legal or financial advice, so your accountant and lawyer apply the valuation in their own fields. Oliver Group's reports follow the guidelines of APES 225 Valuation Services. Oliver Group's fees are set by the annual turnover of the business: a Small Business Valuation is $1,495 + GST for turnover under $2 million, a Medium Business Valuation is $2,495 + GST for turnover between $2 million and $10 million, and a Large Business / Start-Up Valuation is $3,495 + GST for turnover over $10 million or for a start-up. A small-business draft is delivered in 2 business days and a medium-business draft in 3 business days; the delivery date for a Large Business / Start-Up Valuation is agreed before commencement. Delivery time starts once payment and all required information have been received. The fee is fixed in writing before work begins and never depends on the concluded value.
