Around 35 million MOT tests were carried out in the UK last year, according to the Independent Garage Association, with an average failure rate of 27% and the average car on the road now a record 10 years old. Anyone can open a car garage to repair those cars. Testing them needs DVSA authorisation, and making money from either depends on the labour rate.
No licence, registration or qualification is required to repair vehicles for money in the UK. An MOT, by contrast, may only be carried out at premises the DVSA has authorised, by a tester it has qualified, at a price the government caps. That split runs through the whole business.
What is a car repair business?
A car repair business, known in the UK as a car garage, services and repairs vehicles for payment from a workshop, earning mainly from labour hours sold and a margin on parts, and in Great Britain it may also test them if the DVSA has authorised the site as a vehicle testing station. Its income is set by three numbers: the hourly labour rate, the share of paid hours its technicians actually sell, and how many MOTs turn into repair work.
What a garage business typically sells:
- Car servicing and routine maintenance
- MOT testing, where the garage holds authorisation
- Diagnostics and fault finding
- Brakes, clutches, exhausts, batteries and tyres
- Bodyshop work: paintwork, dents, scratches and alloy wheel repair
- Air conditioning and electric vehicle servicing
That is why the trade divides into garages that hold an MOT authorisation and garages that do not, and why it is treated as an asset rather than a formality. It brings vehicles onto the ramp on a legally mandated annual cycle, which no marketing replicates.
How to open a car garage in the UK, step by step
The checklist, in the order openings usually run:
- Decision on MOT testing made before a unit is chosen
- Specialism and target customer fixed
- Unit found with the right planning use and space
- Labour rate calculated from overheads
- Parts accounts opened and a parts policy written
- MOT authorisation applied for and testers qualified
- Diagnostic and EV capability chosen
- Insurance, waste and F-Gas duties in place
- Technicians and apprentices recruited
- Website, reminders and booking system live
1. Decide whether the garage will test
An MOT bay must meet a published layout and equipment standard before the DVSA authorises it, and retrofitting one into a unit chosen for other reasons is expensive. The test itself earns little at a capped fee; its value is that it brings every customer car onto the ramp once a year and produces a list of faults. Authorisation is also closely policed: DVSA figures reported by Garage Wire show 145 authorised examiners and 288 testers had their authorisation withdrawn in 2025/26, out of 23,092 private testing stations.
2. Pick a specialism before a unit
A car garage that takes whatever comes through the door takes the unprofitable jobs too. Ryan Ginifer, a master technician with 19 years running his own business, told Garage Wire that he used to judge the business by the bank balance at month end and accept any work. Since buying William Street Motors in Cleethorpes, he specialises in VW, Audi and Mercedes and competes with main dealers for that work. Common specialisms include a marque group, diagnostics, air conditioning, hybrids and EVs, or fleet and van work.
3. Find a unit that works for a workshop
- Planning use: a unit already in lawful use for vehicle repair is the simplest start; otherwise the council confirms whether a change of use needs permission before a lease is signed
- Space for cars, not just ramps: vehicles waiting for parts, collection or a retest need somewhere to stand, and a unit with ramps but no parking caps the work it can hold
- Catchment over visibility: William Street Motors is hidden from passers-by but sits in a densely populated residential area, and Ginifer says long-standing residents did not know it existed until the website went live
- Power and drainage: ramps, compressors and diagnostic kit need an adequate supply, and oil and wash water need interceptors and drainage the lease allows
4. Calculate the labour rate from overheads
Andy Savva, a garage business coach known as The Garage Inspector, told Garage Wire in 2024 that of the garages he had worked with over five years, only two had fully calculated their overheads and set a profitable hourly rate from them. The common alternative is matching the rate of the car garage down the road. The calculation works from sold hours, not clocked hours:
| Line | Figure |
|---|---|
| Two technicians, 37.5 hours a week, 46 working weeks | 3,450 clocked hours |
| Hours actually sold to customers, at 80% efficiency | 2,760 sold hours |
| Total annual costs: wages, rent, rates, insurance, kit finance, software | £165,600 |
| Break-even labour rate, before any profit | £60.00 an hour |
Illustrative inputs, L’Express Franchise, 30 September 2026. Labour is standard-rated for VAT at 20% once the garage is registered.
Every hour a technician spends waiting for parts, answering the phone or redoing a job raises that figure, which is why workshop efficiency matters as much as the rate itself.
5. Open parts accounts and write a parts policy
Parts come from motor factors on trade accounts, often with several deliveries a day, and the margin on them is the second income line after labour. Customer-supplied parts are a recurring source of disputes over fit and warranty, so many garages set a written policy: declining them, or fitting them at labour cost with no warranty on the part. Parts networks also sell membership: the Eurorepar Car Service network, backed by the Distrigo parts business and its 95-plus sites, passed 300 member garages in 2025 with no franchise fee.
Good to know
The MOT is the only thing a garage sells at a price it does not set. The statutory maximum is £54.85 for a class 4 car, £29.65 for a motorcycle and £58.60 for a class 7 goods vehicle, and the car figure has been frozen since April 2010. A garage may charge less and most do; it may never charge more. The test fee is also outside VAT, while the car repair work the test generates is standard-rated at 20%.
6. Apply for MOT authorisation and qualify the testers
- Authorisation: form VT01 to the DVSA, a nominated authorised examiner designated manager who, on a single site, is a director or the sole trader, a basic criminal record check and a site inspection
- Testers: a Level 2 Award in MOT Testing and a demonstration test, then every year at least three hours of training per vehicle group and a 30-question assessment. Missing it suspends the tester
- Oversight: in 2026 the DVSA expanded its fast-track disciplinary process and is rolling out Photos at Test nationally, so test logs, test times and pass rates per tester are the records a manager reviews
7. Choose the diagnostic and EV capability
Diagnostic equipment and the software subscriptions behind it are a recurring cost, not a fit-out line. Under the Motor Vehicle Block Exemption Order, in force until 31 May 2029, manufacturers cannot restrict independent repairers’ access to the technical information, tools and training needed to repair their vehicles, though access still comes through paid manufacturer portals. EV work needs competence under health and safety law, usually shown through the IMI ladder: Level 2 for routine work around high voltage systems, Level 3 to replace components, Level 4 to diagnose them. In an LKQ Euro Car Parts survey published in September 2026, nearly nine in ten independents said they had turned away or referred EV or plug-in hybrid work in the previous six months.
8. Put insurance, waste and F-Gas in place
- Insurance: motor trade cover including customers’ vehicles in the garage’s custody and on road tests, plus employers’ liability
- Waste: oil, coolant, filters, brake fluid and batteries are mostly hazardous waste, regulated by the Environment Agency in England, SEPA, Natural Resources Wales or NIEA, with a waste carrier registration if the garage moves its own
- Air conditioning: regassing involves fluorinated gases and requires an F-Gas qualification
9. Recruit technicians and train apprentices
No qualification is required by law to work as a mechanic; IMI qualifications and TechSafe registration are what insurers and customers look for. At William Street Motors, Ginifer found college training was not keeping pace with modern vehicles, so he built a training room beside the workshop for his two apprentices. The National Living Wage is £12.71 an hour from 1 April 2026, and employer National Insurance is 0% on an under-21’s earnings up to £50,270, which lowers the cost of apprentices and young technicians. A car garage with one tester ties its MOT income to one person.
10. Build the booking engine
Trust: consumer codes such as Trust My Garage, approved under the Chartered Trading Standards Institute scheme, give a small garage a recognisable standar1 and over, with employer National Insurance at 15% above £5,000 a year. A qualified tester commands well above the minimum.
Website: Ginifer commissioned one the day after buying the garage, and says around 40% of customers now find it through Google search
MOT reminders: the government’s free service texts drivers four and two weeks before the due date, so a car garage’s own reminder has to arrive earlier. An MOT can be taken up to a month, minus a day, early without losing the renewal date, which lets a car garage spread its diary
Retests: a car that fails and is left at the test centre for repair gets a free partial retest within 10 working days, a direct reason for the customer to book the repair on site
Advisories: MOT advisories and minor defects followed up by text or email are the cheapest source of booked work
Types of car repair business
The models differ mainly in whether they carry premises and whether they test.
| Model | What it involves |
|---|---|
| Independent repair workshop | Premises and rates, no DVSA authorisation, income entirely from servicing and repair |
| Garage with an MOT bay | Adds authorisation, an approved bay, qualified testers and an annual assessment cycle |
| Mobile SMART repair | A van and a territory. No premises, no rates, no MOT, cosmetic paint and dent work |
| Fast-fit specialist | Tyres, brakes and exhausts at volume, usually on a main road site |
| Marque or EV specialist | Narrower market, higher diagnostic equipment cost, often higher labour rates |
How much does it cost to open a vehicle repair garage in the UK?
No official UK source publishes an average start-up cost for a car repair business, and equipment prices are quoted by suppliers rather than set by anyone. The statutory and published lines are:
| Cost line | Position |
|---|---|
| Company incorporation | £100 online, Companies House fee schedule from 1 February 2026 |
| Business rates, England | Rateable value × multiplier: 43.2p small business, 48.0p standard |
| Small Business Rate Relief, England | 100% relief at rateable value of £12,000 or less, tapering to nil at £15,000 |
| Staff, from 1 April 2026 | National Living Wage £12.71 an hour, employer National Insurance 15% above £5,000 a year |
| VAT | Registration at £90,000 taxable turnover. The MOT test fee is outside VAT |
| MOT income per test | Capped at £54.85 for a class 4 car, frozen since April 2010 |
| Premises, ramps, bay equipment and diagnostics | No national figure published |
The lines that move a budget most are:
- The unit, its lease, and the rates, where the model uses premises
- Ramps, and the MOT bay equipment where the garage tests
- Diagnostic equipment and the subscriptions that keep it current
- Tester qualification, plus annual training and assessment for every tester every year
- Motor trade insurance covering customer vehicles in the garage’s custody, which in a franchised network is usually specified in the franchise agreement rather than left to the operator
- Waste disposal contracts and the consignment paperwork that goes with them
Car repair franchise opportunities in the UK
Almost nothing franchised in UK car repair is a garage. The automotive franchises recruiting in the UK cluster around mobile work in the aftermarket: SMART repair, car body repair and paintwork, alloy wheel refurbishment, windscreen and glass repair, mobile tyre replacement and valeting.
The franchised model avoids the rates, the lease and the MOT authorisation entirely, which is why it is van-based and why entry is cheaper than a workshop. That pattern holds across the automotive franchises recruiting in the UK.
- ChipsAway, mobile SMART repair covering bumper scuffs, dents and minor paintwork, states on its own site an initial franchise of £29,995 plus VAT, with pricing options requiring £20,000 plus VAT of the franchisee’s own funds. The investment covers training at an IMI-accredited facility, equipment and opening stock. It is part of Franchise Brands plc, a company listed on AIM
- Other automotive networks, including mobile repair and fast-fit brands, recruit in the UK, but no figure from any of their own franchise pages was obtained for this article
A listed parent is useful here for the same reason it was in estate agency: network numbers and divisional turnover appear in audited filings rather than on a recruitment page, even where the initial fee does not, which is the sort of evidence how to choose your franchisor recommends weighing before an application.
Editor’s tip
The MOT is not the product; it is the appointment. At a capped fee frozen for over 15 years, the test itself is close to a loss leader; what it produces is a vehicle on the ramp and an inspection that identifies work. That makes two things commercially decisive. The first is conversion from advisory items to booked repairs. The second is key person risk: in a garage with one tester, the MOT income depends on one individual passing a 30-question assessment each year, and a failure suspends testing until a further demonstration test with the DVSA has been passed.
Garage margins and the difficulties operators report
- A labour rate copied from a rival: it ignores the garage’s own overheads and efficiency, the gap Savva describes
- A fixed test price against rising costs: the car MOT cap has not moved since 2010 while wages and rates have
- Key person risk: one tester failing the annual assessment suspends testing until a new demonstration test is passed, and on a single site the designated manager must be an owner
- EV and data access: the LKQ survey found 27% of independents name diagnostic access for newer EV brands as the main barrier to investing in EV work
- Skills: apprentices arrive with gaps, and trained technicians are recruited by dealers and fast-fit chains
The bottom line
- A car repair business needs no licence and no qualification to open in the UK
- MOT testing needs DVSA authorisation of the premises, a designated manager who owns the business, and qualified testers
- The test is capped at £54.85 for a car and has been since 2010
- The authorisation earns its keep by bringing vehicles in, not by what it charges
- Waste, planning and F-Gas duties apply to the repair side regardless
- Franchising in this sector is mostly mobile and premises-free, from £29,995 plus VAT
Frequently asked questions about opening a car garage in the UK
No, not to repair vehicles. There is no licence, registration, or mandatory qualification for carrying out paid car repair in the UK. MOT testing is separate: the premises must be authorised by the DVSA following an application on form VT01 and an inspection; the business must nominate an authorised examiner designated manager, and the testing must be done by qualified MOT testers. Planning permission, waste registration and workshop safety duties apply to the repair side regardless.
By applying to the DVSA on form VT01 as the legal entity that will control the testing, nominating an authorised examiner designated manager who, on a single site, must be a director or the sole trader, providing a basic criminal record check, and having the premises inspected. The bay must meet the specified layout and use equipment from the DVSA’s list of acceptable equipment. Testing itself must be carried out by someone holding a Level 2 Award in MOT Testing who keeps up the annual training and assessment.
No qualification is required by law to work as a mechanic or to run a car repair business. The Institute of the Motor Industry is the sector awarding body; its qualifications are regulated by Ofqual, and its TechSafe recognition places qualified technicians on a public professional register. None of it is compulsory, though insurers, manufacturers and trade customers commonly ask for it. Electric vehicle work is the exception in practice: there is no statutory licence, but health and safety law requires competence, and the IMI ladder runs from Level 2 to Level 4.
No more than the statutory maximum, which is £54.85 for a class 4 car, £29.65 for a motorcycle and £58.60 for a class 7 goods vehicle. The car figure has been unchanged since April 2010. A garage may charge below the cap and most do, so the test is commonly priced well under the maximum. The test fee is outside VAT, while repair work is standard-rated at 20%.
