How much does an MOT cost in 2026?
5 September 2026·5 min read
The test fee is capped by law
For a car (class 4), the most any garage can charge for the test itself is £54.85. That cap is set by the DVSA, and it covers the test only, not any repairs. Many garages charge less, often between £35 and £45, and use the test as a way to win servicing work.
A cheap test is the same test. Every authorised tester follows the same manual and records the result on the same national system, so a £35 pass counts exactly as much as a £54.85 one. What differs is what happens next if the car fails.
Retests: when they are free and when you pay again
If the car fails and the same garage does the repairs, the retest is usually free provided it happens within 10 working days. That is the deal most drivers get, and it is worth confirming before the test starts rather than after a failure.
If you take the car away and bring it back later, or take it to a different garage entirely, expect to pay for a full test again. A car that failed still needs a valid pass on record, and there is no discount for the second attempt.
The repairs that actually cost money
The test fee is the small part of most MOT bills. What hurts is the work a failure uncovers, and those costs are predictable. A bulb is under £10. Tyres start around £60 fitted. Discs and pads usually run £150 to £350 per axle, and suspension arms or bushes £120 to £300 a side, depending on the car.
The same few areas fail most cars every year: lamps, tyres, brakes and suspension. Those are wear items with visible warning signs, which means most of the bill is avoidable with a look over the car before you book.
How to keep the bill down
Run the DIY pre-MOT checklist first: lights, tread depth, wipers, horn, mirrors and warning lamps. Each one takes seconds and each one fails cars every day. Fix at home what costs pounds at home, because the same job on test day comes with labour on top.
Read your advisories from last year before you book. An advisory is the tester telling you what will likely fail next time. Fixing it in January on your terms is almost always cheaper than meeting it on MOT day.
