Anyone can repair cars for money in the UK. No licence, no registration, no qualification is required to open a garage and charge for the work. Testing those same cars is different: an MOT may only be carried out at premises the DVSA has authorised, by a tester it has qualified, at a price the government caps by law.
That split runs through the whole business. Repair work is governed by ordinary contract and consumer law, workshop safety rules and waste duties. MOT testing is a separate authorisation with its own application, its own qualifications, its own annual assessment and its own statutory price ceiling. Vehicle testing in Great Britain is run by the DVSA; Northern Ireland tests through DVA-operated centres rather than private garages. Waste and environmental duties are split across all four nations.
What is a car garage business?
A car garage business services and repairs vehicles for payment from a workshop, and in Great Britain it may also test them if the DVSA has authorised the premises as a vehicle testing station and qualified the people doing the testing. The repair side needs no permission to begin. The testing side cannot begin at all until an application has been approved and the site inspected.
That is why the trade divides into garages that hold an MOT authorisation and garages that do not, and why the authorisation is treated as an asset rather than a formality. It brings vehicles onto the ramp on a legally mandated annual cycle, which no amount of marketing replicates.
How to open a car garage in the UK, step by step
A repair-only car garage can trade as soon as it has premises, insurance and a competent mechanic. Everything below the third step applies only to businesses that want to test.
What a car garage needs in place before it opens:
- Premises whose planning use covers vehicle repair, confirmed with the council
- Employers’ liability and motor trade insurance, including vehicles in the garage’s custody
- Registration as a waste producer, and a carrier registration if waste is moved
- A COSHH assessment and safe systems for lifting equipment and ramps
- DVSA authorisation, a nominated AEDM and an approved bay, if MOTs are to be done
- Registration as self-employed or a company at Companies House
1. Decide whether the garage will test
This decision shapes the premises, the equipment budget and the recruitment. A repair-only workshop can take almost any industrial unit with a ramp. An MOT bay has to satisfy a specified layout and equipment standard before authorisation is granted, and retrofitting one into a unit chosen for other reasons is expensive.
2. Confirm the planning position on the unit
Vehicle repair generates noise, fumes and vehicle movements, and local planning authorities treat it accordingly. A unit already in lawful use as a car garage is the simplest starting point, and where the previous use was something else the council confirms whether a change of use needs permission before a lease is signed.
3. Apply for MOT authorisation
The application is form VT01, made to the DVSA by the legal entity that will hold full control and responsibility for testing. The applicant becomes an authorised examiner and must nominate an authorised examiner designated manager. For a single site, the AEDM has to be a director of the company or the sole trader, so this is not a role that can be delegated to a mechanic. A basic criminal record check forms part of the application, and the AEDM takes a management qualification. DVSA inspects the premises before final authorisation is granted.
4. Qualify and keep qualifying the testers
A new tester takes a Level 2 Award in MOT Testing and passes a demonstration test overseen by the DVSA. After that, the obligation is annual: at least three hours of training each year for each vehicle group tested, plus an annual assessment of 30 multiple-choice questions, completed within the testing year. A tester who does not pass and record the assessment by the deadline is suspended from testing until they have completed the following year’s training, passed that assessment and taken a further demonstration test with the DVSA.
5. Equip the bay to the published standard
Brake and headlamp testing equipment is normally selected from the DVSA’s list of acceptable equipment, and equipment outside that list is referred to the agency. There is a limited concession for remote rural sites, where premises 15 miles or more by road from a compliant station and expecting no more than 350 tests a year can be considered on a more flexible basis.
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 repair work the test generates is standard-rated at 20%.
6. Set the skill level for the work you take on
No qualification is required by law to work as a mechanic in the UK, which surprises most people opening a car garage. What exists instead is a sector framework: the Institute of the Motor Industry is the awarding body, its qualifications are regulated by Ofqual, and its TechSafe recognition puts qualified technicians on a public professional register maintained through continuing development. None of it is compulsory. Insurers, manufacturers and trade customers commonly ask for it anyway, and a franchisor would set its own standard through the operating manual rather than relying on the statutory position.
Electric vehicle and hybrid work is where that gap matters most. There is no statutory licence to work on a high voltage system, but health and safety law requires the people doing it to be competent, and the recognised route is the IMI ladder: Level 2 for routine maintenance around a high voltage system, Level 3 to remove and replace high voltage components, and Level 4 for diagnosis, testing and repair of those components. A car garage that takes electric vehicle work without that training is carrying a risk its insurer is likely to ask about.
7. Set up the waste and environmental duties
Waste oil, coolant, filters, brake fluid, batteries and tyres are the routine output of a workshop and most of it is hazardous waste. The regulator depends on the nation: the Environment Agency in England, SEPA in Scotland, Natural Resources Wales, and the Northern Ireland Environment Agency. A garage that moves its own waste needs to register as a waste carrier with the relevant body.
8. Check the air conditioning position
Work on vehicle air conditioning involves fluorinated greenhouse gases, and handling them requires the relevant F-Gas qualification. A garage offering air conditioning regas without it is doing regulated work without the certification the work requires.
9. Register the business and sort the tax
Incorporation at Companies House costs £100 online on the fee schedule in force from 1 February 2026. VAT registration becomes compulsory once taxable turnover passes £90,000, and in a garage the mix matters, since the MOT fee itself sits outside VAT while parts and labour do not.
10. Recruit for the bay, not just the ramp
A garage with one qualified tester has its MOT income tied to one person’s annual assessment and availability. The National Living Wage is £12.71 an hour from 1 April 2026 for anyone aged 21 and over, with employer National Insurance at 15% above £5,000 a year, and a qualified tester commands well above the minimum.
Types of car garage 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 car garage in the UK?
No official UK source publishes an average start-up cost for a car garage, 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 garage franchise opportunities in the UK
Automotive franchising in the UK is concentrated in mobile cosmetic repair rather than in premises-based garages, which is a meaningful distinction: the franchised model avoids the rates, the lease and the MOT authorisation entirely. 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.
The practical difficulties operators report
- The test price is fixed and the costs are not. The class 4 cap has not moved since April 2010 while wages, rates and equipment have
- Authorisation attaches to premises and people. Moving site or losing a tester interrupts testing, not just staffing
- The annual assessment never stops. Three hours of training and a pass, every year, for every tester, for every vehicle group
- The AEDM must be an owner. On a single site, the role sits with a director or the sole trader, so it cannot be delegated away
- Waste is a four-nation problem. A car garage group operating across borders deals with four separate environmental regulators
- Diagnostics date quickly. Equipment and subscriptions are a recurring cost, not a one-off fit-out line
The bottom line
Opening a car garage in the UK requires no permission at all until the business wants to test, at which point it needs DVSA authorisation of the premises, a designated manager who is an owner of the business, qualified testers and an annual assessment that never ends. The test itself is capped at £54.85 for a car and has been since 2010, so the authorisation earns its keep by bringing vehicles in rather than by what it charges. Franchising in this sector is mostly mobile and premises-free, which sidesteps the rates and the authorisation but also the recurring work the MOT cycle delivers.
Frequently asked questions about opening a car garage in the UK
Not to repair vehicles. There is no licence, register or mandatory qualification for carrying out paid vehicle 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 testers. Planning permission, waste registration and workshop safety duties apply to the repair side regardless.
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%.
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.
