What is a pre-MOT check and is it worth it?
A pre-MOT check is an informal inspection a garage carries out before your official MOT, to find the faults most likely to fail the test. It is not a legal test and does not go on record, but it lets you fix small problems in advance so you pass first time and avoid a failure and a retest. Many garages offer a basic pre-MOT check cheaply or free, especially if you book the MOT with them.
An MOT failure is frustrating, and most of the common reasons are small, cheap things that could have been caught beforehand. That is exactly what a pre-MOT check is for. It is a quick inspection a garage carries out before your official test, designed to flag the faults most likely to fail you, so you can put them right and pass on the day. This guide explains what it covers, what it costs and when it is genuinely worth booking.
What a pre-MOT check is, and is not
A pre-MOT check is a preview, not the legal test. It does not go on the MOT record, it does not extend your current certificate and it has no legal status of its own. Its single purpose is to predict how your car would do so you have time to fix anything before the real thing. The official MOT is separate, and our guide on what is checked in an MOT sets out everything the tester assesses.
What it looks at
A typical pre-MOT check runs through the parts that fail the most cars. That means all the lights and bulbs including indicators and brake lights, the tyres for tread depth and condition, the brakes and brake fluid, the wipers, washers and screen wash, plus the horn, mirrors, number plate and any visible leaks, damage or warning lights on the dashboard. On a ramp a garage can also look at the suspension and underneath, which is where the less obvious failures hide.
Why it is worth it
The value is simple. According to DVSA figures, a large share of MOT failures come from straightforward items like lighting, tyres and wipers, the very things a pre-MOT check finds. Fixing a blown bulb or a worn wiper blade in advance costs very little, while failing means a repair, a possible retest and time when the car may not be legal to drive. If the failure is a dangerous one, you should not drive the car away at all. Catching it early keeps you in control of both the cost and the timing.
What it costs
Prices vary. Many garages offer a basic visual pre-MOT check for a modest fee, and plenty do it free when you book the MOT itself with them. A fuller inspection on a ramp costs a little more but is sensible if you have felt anything wrong with the brakes or suspension, or if the car has covered high mileage since its last service.
Doing some of it yourself
You can cover the easy wins at home the day before. Walk around the car and check every light works, look at the tyre tread and pressures, top up the screen wash, test the wipers and washers, and sound the horn. Our guide on how to prepare for your MOT lists the simple checks anyone can do without tools, and they remove a good number of avoidable failures on their own.
The bottom line
A pre-MOT check is a cheap insurance policy against an avoidable failure. It is most worthwhile when your MOT is due, the car has done a lot of miles, or something has felt off. Book it a week or two before the test so there is time to fix anything it finds. You can compare local garages for your MOT, see their ratings and availability, and send a booking request in about a minute. You pay the garage directly and there is no booking fee. If you want to know what the test itself should cost, our guide on how much an MOT costs explains the capped fee.

- You can do some of the checks yourself the day before.
Frequently asked questions
Is a pre-MOT check the same as an MOT?
No. A pre-MOT check is an informal inspection to predict how your car would do. It is not a legal test, does not appear on the MOT record and does not extend your MOT. Its only job is to catch likely failures so you can fix them before the real test.
How much does a pre-MOT check cost?
It varies. Many garages offer a basic visual pre-MOT check for a small fee, and some do it free when you book the MOT with them. A more thorough check on a ramp costs a little more but can be worth it if you suspect brake or suspension issues.
Is a pre-MOT check worth it?
It is most worth it if your MOT is due, the car has covered a lot of miles, or you have noticed anything not quite right. Fixing a blown bulb or a worn wiper in advance is far cheaper and quicker than failing, and it keeps you legal on the road.
Can I do my own pre-MOT check?
You can cover the basics yourself: check all your lights work, look at tyre tread and pressures, top up screen wash, test the wipers and washers, and sound the horn. Our guide on preparing for your MOT walks through the simple checks anyone can do.
Will a pre-MOT check guarantee a pass?
No inspection can guarantee a pass, because some faults only show under the full test. But a good pre-MOT check dramatically reduces the risk by catching the common, avoidable failures in advance.
