Every car in the UK that is more than three years old needs an annual MOT test. For London drivers, finding the right DVSA-approved testing centre — and understanding what the test actually covers — can save time, money and the stress of an unexpected failure.
What does an MOT test cover?
The MOT checks 44 key areas including:
- Lights (headlights, brake lights, fog lights, indicators)
- Steering and suspension
- Brakes (effectiveness, condition of pads, discs and cables)
- Tyres (tread depth, condition, correct specification)
- Seatbelts and airbag warning light
- Exhaust emissions
- Windscreen, wipers and washers
- Bodywork (sharp edges, structural integrity)
- Vehicle identification number (VIN)
The test does not assess the condition of the engine, gearbox or clutch.
What is the MOT cost in London?
The maximum legal fee for an MOT in England is £54.85. Most garages charge at or near this. Some national chains offer discounted MOTs (£25–£40) but make their money on repairs. Factor in the cost of any advisory work when comparing MOT prices across London garages.
How to prepare for your MOT
Simple checks you can do yourself before the test:
- Check all lights are working (get someone to help with brake lights)
- Check tyre tread depth — insert a 20p coin into the main groove. If you can see the outer band, the tyre may be near the legal limit.
- Top up washer fluid
- Check wiper blades are not streaking
- Ensure the horn works
- Remove any cracked or chipped windscreen (if in driver's line of sight)
What happens if my car fails its MOT?
A failure means your car is not roadworthy and should not be driven (except to a garage for repairs). Your existing MOT certificate remains valid for its original duration while repairs are carried out. If the same garage carries out the repairs, most offer a free partial retest within 10 working days. After this period, a full retest fee applies.
