An MOT certificate is valid for exactly one year. An MOT lasts for a year and is valid until midnight of its expiry date. That sounds simple, but the rules around early testing, grace periods and renewal dates trip up thousands of drivers every year. The maximum a garage can charge for a Class 4 car test is £54.85, although most charge less, so there is no financial reason to leave it to the last minute.
This guide covers when your MOT expires, how to check the exact date, when to book, what happens if you forget, and the 2026 rule changes worth knowing about. UK only. England, Scotland and Wales follow DVSA rules; Northern Ireland is run by the DVA and works slightly differently.
When exactly does an MOT expire?
Your MOT runs out at the end of the date printed on your certificate. An MOT is valid for 12 months. This is calculated from the date of your test to the exact same date the following year. So if you passed on 14 May 2025, your certificate expires on 14 May 2026.
The expiry runs to the end of that day. You can drive your car until midnight on the date of expiry. After this time, you cannot drive the vehicle unless you are driving directly to an approved MOT test centre for a pre-booked appointment, or to a garage for necessary repairs. From 00:01 the next morning, the car is treated as having no MOT at all.
How to check your MOT expiry date
There are three reliable ways to find your expiry date:
- Look at your current paper certificate. The date is printed near the top.
- Use the free government tool at check-mot.service.gov.uk. The quickest way to check your exact due date is the DVSA's free online check at check-mot.service.gov.uk, you only need the registration number. The result shows your current MOT expiry date, whether the vehicle is taxed, and the full test history going back to 2005.
- Run a quick lookup with our MOT check tool, which pulls the same DVSA data and shows past advisories alongside the expiry date.
A reminder letter from the DVLA usually lands a few weeks before the deadline, but do not rely on it. The DVLA also sends a reminder letter ahead of your MOT expiry, but these are not guaranteed to arrive, particularly if your address on the V5C is out of date. Relying on a reminder letter is not a safe approach. Setting a calendar reminder a month before the expiry date is more reliable.
When does a brand-new car need its first MOT?
New cars get a three-year holiday. A new car will need its first MOT, by law, three years after it was first registered in the UK. If your car was registered on the 1st September 2023, it will need its first MOT on the 1st September 2026.
There has been chatter about pushing this out to four years, but nothing has changed. There have been periodic discussions about extending the first MOT to 4 years for new vehicles, but as of 2026 the rules remain unchanged: first MOT at 3 years, then annually. Bought a three-year-old used car? Check the registration date on the V5C and book in straight away if needed.
The one-month-minus-a-day rule
You do not have to wait until the day your certificate runs out. If your MOT runs out on 15 May, the earliest you can get an MOT to keep the same renewal date for next year is 16 April. You can get an MOT earlier, but the renewal date for the following year will change to one year (minus a day) from the date the vehicle last passed its MOT.
In practice, this means booking 28 to 30 days before expiry gives you the best of both worlds. If you book your MOT early, it becomes valid for up to 13 months (the 12 months from your expiry date this year to the following year, plus up to an additional 30 days. This depends on how early you booked your MOT). Book too early, say six weeks ahead, and you effectively shorten the cycle by losing those bonus weeks for the rest of the car's life.
Quick worked example
- Current expiry: 30 June 2026.
- Earliest test for same renewal date: 1 June 2026.
- If you test on 28 May 2026 and pass, your new expiry becomes 27 May 2027.
- If you test on 30 June 2026 and pass, your new expiry stays as 30 June 2027.
What happens if your MOT expires?
There is no grace period. None. There is no grace period after your MOT expires. From midnight on the expiry date, the vehicle is technically unroadworthy and the penalties apply. The only exception is driving directly to a pre-booked MOT or to a garage for repairs identified in the last test.
The fines are not trivial. Driving without one is an offence that can result in fines. A fixed penalty notice typically costs around £100, but the law allows fines of up to £1,000. If your vehicle has a dangerous defect, a fault serious enough to fail the test, you could be fined up to £2,500 and receive three penalty points. Repeat offences can lead to a driving ban.
Worse, your tax falls into the same hole. If your tax is due to run out, register your vehicle as 'off the road', you cannot renew your vehicle tax if your MOT has expired. And the police do not need to pull you over to spot the problem. Police forces use Automatic Number Plate Recognition (ANPR) cameras that scan your number plate and check it against the DVSA database.
What if you fail the test before the old certificate runs out?
This is where many drivers get caught out. If your car fails the MOT test the expiry date of your current MOT still stands. But you can't continue using your car until the certificate expires. It's an offence to drive an unroadworthy vehicle that has failed its MOT because of a dangerous problem.
So a fail with a major or minor defect on a certificate that is still in date? You can technically drive it home if it is not dangerous. A dangerous fault flagged on the test sheet? The car stays at the garage until it is fixed. The tester will tell you in plain terms.
A free or reduced-fee retest is often available if you sort the issue quickly. An MOT retest is free if your car fails on one or more of the areas outlined in the table below and the repair(s) is completed within 1 working day. Ask the garage about the retest policy before you leave.
Exemptions: when an MOT is not required
A small group of vehicles do not need an annual MOT at all. Vehicles first registered more than 40 years ago are exempt from the annual MOT test, provided no substantial changes have been made to the vehicle in the last 30 years. This exemption covers most pre-1985 cars and motorcycles.
If you are not using the car at all, you can declare it SORN. If you want to keep your car on private lands, i.e., a territory not owned by a government like your private driveway or garage, you need to register it as off-road. If you get a SORN (statutory off road notice), you will no longer need an MOT for this car. You still cannot park it on a public road, though.
2026 changes worth knowing
The core MOT rules have not shifted in 2026, but two behind-the-scenes changes affect how tests are carried out. The main changes in 2026 include tester restriction rules (from January 2026, MOT testers can no longer test vehicles owned by their employer or themselves), new jacking equipment requirements for heavier electric vehicles (from April 2026), an expanded photo evidence system to combat fraud, and potential updates to emission testing standards for newer Euro-compliant vehicles.
The maximum test fee has not budged. The maximum test fee is £54.85 for a car, set by the DVSA. Garages can and often do charge less, typical market rates are £30 to £45. VAT is not charged on the test fee itself but is charged on any repair work. The government has announced a consultation on reviewing the fee cap later in 2026, as it has remained unchanged since 2010.
Booking your next MOT
Once you know your expiry date, the rest is straightforward. Pick a DVSA-approved test centre, book in around 28 days before expiry, and bring just the car. The tester pulls everything else from the database.
