When does my MOT expire?

How the expiry date is set

A car needs its first MOT on the third anniversary of its registration. After that, the certificate normally runs for one year from the date of the test.

The exception is the rule that matters. If you test in the month before your current certificate expires, the new certificate is dated from the existing expiry date rather than the test date. So testing early inside that window costs you nothing — you keep the same anniversary and gain the flexibility of not testing at the last minute.

Test earlier than that window and the clock resets to the test date, which quietly shortens the cycle. Do that a few years running and your MOT anniversary drifts several weeks earlier, which is one of the more common reasons the date is not what people expect.

• First MOT: due on the third anniversary of first registration
• Then annually, normally one year from the test date
• Test within the month before expiry: the new certificate runs from the old expiry date
• Test earlier than that: the anniversary moves to the new test date
• A retest after a failure does not extend the expiry beyond the normal cycle

Why your expiry date might not be what you think

Several ordinary things move it, and none of them is an error.

The most common is the drift described above from repeatedly testing too early. The second is a change of keeper — the certificate belongs to the vehicle, not the owner, so a car you have just bought carries whatever date the previous owner's testing pattern produced. The third is a period on SORN: the expiry does not pause while a car is off the road, so a vehicle brought back into use may need testing immediately.

There is also a category of vehicle where the answer is simply that there is no expiry to find: a car under three years old has never been tested, and a genuinely MOT-exempt vehicle may have no current certificate by design.

What happens on the day it expires

There is no grace period. The certificate expires at the end of its expiry date and driving on a public road after that is an offence in its own right, punishable by a fine of up to £1,000 — and up to £2,500, with a possible disqualification, if the vehicle is in a dangerous condition.

There are two narrow exceptions: driving to a test that is already booked, and driving to or from a garage for repairs that have been arranged as a result of a failed test. Neither is a general permission to keep using the car.

The knock-on effects matter as much as the fine. Vehicle tax cannot be renewed without a valid MOT, so a lapsed test will block a tax renewal or stop a direct debit. And enforcement is automatic — automatic number plate recognition cameras query the same record continuously, so an expired MOT does not require anyone to stop the car to be detected.

Making sure you do not miss it

The failure mode is almost never that people decide to risk it. It is that the date passes unnoticed, usually in the month after a house move, a car purchase or a change of insurer.

Three defences work. Check the date on the DVSA record rather than relying on the certificate in the glovebox, which may be for a superseded test. Set a reminder a month ahead rather than a week — that puts you inside the window where testing early preserves your anniversary. And check the tax due date at the same time, because the two are linked and a lapsed MOT is the usual cause of a failed tax renewal.

We offer a free MOT reminder: enter a registration and an email address and we will email you before the expiry date on the DVSA record. It is free, there is no account, and you can unsubscribe from any message.

Checking it now

Our free check returns the MOT status and expiry date from the DVSA record for any UK registration, along with the full test timeline: every test since 2005 with its result, the mileage the tester recorded, the defects and the advisories, plus the DVLA tax status and any open safety recall.

It costs nothing and needs no card or account. And the usual honest caveat applies: a valid MOT means the vehicle met the minimum standard on the day it was tested. It is not a statement that the car is currently in good condition, and an expiry date several months away tells you nothing about what has worn out since.
