Does the MOT transfer when I buy a used car?

Yes, in the sense that matters: the MOT is recorded against the vehicle, not against whoever owns it, so the expiry date does not change when the car is sold. GOV.UK sets the deadline by the car itself — the third anniversary of registration for a first test in Great Britain, then the anniversary of its last MOT — and none of those dates reference the keeper. Nothing needs to be done to move it across, and the new keeper inherits the remaining months exactly as they stood. Check the expiry yourself on the free GOV.UK history service rather than taking the certificate in the glovebox on trust: it shows every test, pass or fail, with the recorded mileage each time.

What the rule actually says

GOV.UK sets the MOT deadline against the vehicle: the third anniversary of registration for a first test in Great Britain, and after that the anniversary of its last MOT. Neither is expressed in terms of who owns the car, which is why a sale changes nothing about the date. Strictly, GOV.UK does not use the word “transfer” at all — there is nothing to transfer, because the certificate was never attached to a person in the first place. That is our reading of the rule rather than a phrase you will find on GOV.UK, and it is worth saying which is which.

Northern Ireland is tested by the DVA under separate rules, and a first test falls at 4 years rather than 3. Everything below describes Great Britain unless it says otherwise.

The one month minus a day rule

GOV.UK states you can test “up to a month (minus a day) before it runs out and keep the same renewal date”. So a certificate expiring on 20 September can be tested from 21 August and still expire on 20 September next year. Go earlier than that window and the new certificate runs one year (minus a day) from the day it passes, quietly costing you the difference every year you do it. Our MOT due date checker works out that window for you from the date of the last MOT.

This matters more when buying than people expect. A car sold with a fresh MOT may have been tested well before it was due, which does not shorten your cover — but a car sold with “eleven months MOT” has an anniversary that is now eleven months away, not twelve, and that date is the one you inherit.

Selling instead? The MOT is one of the things a buyer will check, and selling a car privately in the UK covers what else a private sale involves, from the log book to the vehicle tax refund.

Check the record, not the certificate

The free GOV.UK MOT history service shows every test a vehicle has had since 2005, pass or fail, with the mileage recorded each time and every advisory noted. It is the single most useful free check on a used car, and it is the one a paper certificate cannot give you: a run of mileages tells you whether the reading in front of you is plausible, and a pattern of repeat advisories tells you what the car keeps needing. You can run it on any registration before you travel to see the car. How to prove a car’s mileage has been altered shows how to read the mileages it lists, and what an advisory actually is covers the grading.

Questions people ask

I have just bought a car with a few weeks of MOT left — when should I test it?
Inside the last month of the certificate, because a test in that window keeps the existing renewal date rather than resetting it. Testing sooner than that moves the anniversary to one year (minus a day) from the test, so you give up the days in between — and since you inherited this date with the car, that is the one chance to keep it somewhere convenient. Check the exact expiry before booking; it belongs to the vehicle and did not reset when you bought it.
When is a used car due its first MOT?
In Great Britain a car's first MOT is due on the third anniversary of registration, so a car registered in June 2023 is first tested by June 2026. Northern Ireland is tested by the DVA under separate rules and the first test there falls at 4 years. After the first test, the deadline in both is the anniversary of the last one.
Can I drive a car home if its MOT has expired?
GOV.UK gives two exceptions: to or from somewhere to be repaired, or to a pre-arranged MOT test. Driving it anywhere else without a valid MOT is an offence, and your insurance may not respond. If you are buying a car whose MOT has run out, book the test before you collect it rather than after.
Does a long MOT mean the car is in good condition?
Not on its own. An MOT is a minimum roadworthiness check on the day of the test and says nothing about the condition of the engine or gearbox, or about what has been done since. A fresh certificate with a list of advisories can tell you more than a clean one with ten months left — the advisories are the tester writing down what is on its way to failing.
