Car service vs MOT in Wales

An MOT and a service are two jobs. The Class 4 test cannot exceed £54.85. A service has no official price. Ask for each figure. A serviced car can still fail the test.

An MOT and a service are two bills. Mixing them is how garages sell a bundle. The law only caps the test.

MOT

A legal inspection against the minimum standard. Class 4 maximum £54.85 nationwide, including Wales. No VAT on the test fee. Stations may charge less. See how much an MOT costs and what a fail means.

Service

Oil, filters, and whatever the garage scoped. There is no official service tariff. Interim, full and major are marketing names, not DVSA classes.

You can service a car on Monday and fail the MOT on Tuesday if a legal item (tyres, lights, corrosion) is wrong.

Ask for each price. A “service and MOT” poster is a package, not a change in the law.

Common questions

Is a service the same as an MOT?
No. The MOT checks the minimum legal standard. A service replaces oil, filters and whatever the garage scoped. You can fail an MOT on a freshly serviced car if a legal item is wrong.
Does the MOT fee include a service?
No. Bundled ‘service and MOT’ deals are marketing. Ask for each price. The test itself cannot exceed £54.85 for Class 4.
