MOT testing is regulated; repairs are not
The MOT is a statutory annual test for most vehicles over three years old, carried out only at stations authorised by the Driver and Vehicle Standards Agency. Results go onto a central record, so you can check any vehicle’s MOT history and current status online using its registration.
General servicing and repair work carries no equivalent licensing. A garage that is a legitimate MOT test station is regulated for that activity, but its repair work sits under ordinary consumer law rather than a sector licence.
Check the history before you buy
The free MOT history service shows past results, recorded mileage at each test, and advisory items. Mileage that does not increase consistently between tests is worth questioning.
Fails, advisories and dangerous defects
Defects are categorised. Dangerous and major defects mean a fail; a dangerous defect means the vehicle should not be driven away. Minor defects and advisories do not fail the test but flag items likely to need attention.
A test station may offer to carry out the repairs. You are entitled to take the vehicle elsewhere for the work, and for larger bills, a second opinion is reasonable rather than rude.
Warranties and independent garages
A common worry is that servicing outside a franchised dealer voids the manufacturer warranty. In general it does not, provided the work follows the manufacturer’s schedule and uses parts of the appropriate specification, and the work is documented.
Keep the invoices and stamps. The evidence trail is what protects you if a warranty claim is later questioned.
Your rights if a repair goes wrong
Repair work is a service supplied to you as a consumer, and it must be carried out with reasonable care and skill. If it is not, you are entitled to have it put right, and to a price reduction if repeating the work is not practical.
Ask for the old parts back where feasible, keep the itemised invoice, and put complaints in writing. Some garages subscribe to a voluntary code of practice with an ombudsman scheme, which gives you an escalation route short of court.
Getting a fair quote
- Ask for an itemised written estimate before authorising work.
- Set a limit above which the garage must call you before proceeding.
- Ask whether parts are original, matching-quality or reclaimed.
- Confirm what guarantee applies to parts and to labour.
- Ask whether diagnostic time is charged separately and whether it is deducted if you go ahead.
Frequently asked questions
- Can I check a car’s MOT history for free?
- Yes. The government MOT history service lets you check any UK vehicle’s test results, recorded mileage and advisories using its registration number.
- Does servicing at an independent garage void my warranty?
- Generally no, provided servicing follows the manufacturer’s schedule, uses parts of the correct specification, and is properly documented. Keep the invoices as evidence.
- Do I have to have repairs done where the MOT was carried out?
- No. You can take the vehicle elsewhere for any work identified, and for a significant bill a second opinion is entirely reasonable.
- What is the difference between an advisory and a fail?
- Advisories and minor defects are recorded but do not fail the test. Major and dangerous defects fail it, and a vehicle with a dangerous defect should not be driven until repaired.
