How much does an MOT cost?
The most a test centre can legally charge for a car MOT is £54.85. Many charge less (£30 to £45 is common) and there is no VAT on the fee. The test is the same everywhere; only the price changes.

The maximum fee, and why it is a maximum
The government sets a cap on what an MOT test may cost, not a fixed price. For a car with up to eight passenger seats (a class 4 vehicle, which is almost every private car), the cap is £54.85. A test centre can charge anything up to that, and none may charge more for the test itself.
Because the test is identical wherever you take it, a cheaper MOT is not a worse MOT. The tester follows the same inspection manual and records the result on the same national database. What changes between garages is how they make their money.
Why some garages are so cheap
A garage advertising a £25 MOT is usually hoping to do the repairs as well. That is not necessarily a problem (a fail is a fail and the work needs doing somewhere), but it is worth knowing that you are free to take the failure sheet and get quotes elsewhere.
Council-run test centres are worth knowing about for the opposite reason. They test but do not repair, so they have no interest in finding work that is not there. Many councils will test private cars.
What happens if it fails
If the car fails and you leave it at the test centre for repairs, the partial retest within 10 working days is usually free. If you take it away and bring it back within the next working day for certain items (lights, wipers, mirrors, number plates and similar), that retest is free too.
Take it away for repairs elsewhere and return within 10 working days, and the centre can charge up to half the full fee for the partial retest. After 10 working days it is a full new test at full price.
If the failure includes a dangerous defect, you should not drive the car away at all until it is fixed.
How to pay less without cutting corners
Check the obvious things yourself the week before: every bulb, the horn, the wiper blades, washer fluid, tyre tread and pressures, and that no warning lights are on. A large share of failures are for things a driver could have spotted in five minutes.
Book early. You can have the test up to a month (minus a day) before the current certificate expires and keep the same renewal date, which gives you time to shop around for repairs rather than paying whatever is asked the day before it runs out.

Common questions
Is there VAT on an MOT?
No. The MOT test fee is exempt from VAT. Any repairs carried out afterwards are charged with VAT as normal.
Can a garage charge more than £54.85 for a car MOT?
Not for the test itself. £54.85 is the legal maximum for a class 4 vehicle. Repairs, parts and labour are charged separately.
Is a cheap MOT less thorough?
No. Every test centre follows the same inspection manual and records the result on the same national database, whatever it charges.
