An MOT certificate lasts for one year, according to GOV.UK, and the expiry date shown on the certificate or in the MOT history sets the deadline for your next test. You can book the test up to a month minus a day before the current MOT runs out and still keep the same renewal date. Testing any earlier than that changes the date, and once the MOT has run out the car must not be driven on the road. The sections below explain each situation and what to do in it.
When is your MOT due?
A vehicle needs its first MOT by the third anniversary of its registration. Some vehicles must be tested at one year old instead, and GOV.UK’s MOT fees table shows which types are affected, so check there if your car is a type you are unsure about. After the first test, the next one falls due on the anniversary of the last MOT, so each new certificate builds on the one before it. Keeping that chain in mind helps you avoid losing track of the date after a few years of renewals.
How do you check your MOT expiry date?
Two sources give you the date. The MOT history service on GOV.UK lets you look up a vehicle’s past test results and shows when the next test is due, which makes it the most reliable place to check. For tests in England, Scotland and Wales, the same service also shows the mileage recorded at each test, which parts failed or had minor problems, and lets you download current and previous certificates. The date printed on your current certificate gives the same expiry information if you have a copy to hand. If the two ever seem to disagree, rely on the official MOT history and contact a test centre to confirm before you drive. Checking before buying a used car is worthwhile too, because the MOT belongs to the vehicle, not to the seller.
How do you renew early and keep the same renewal date?
Renewing within the permitted window is the simplest way to keep your date. Using GOV.UK’s example, if the current MOT runs out on 15 May, the earliest test that keeps the same renewal date is 16 April. A pass taken from 16 April onward, while the current certificate is still valid, keeps the renewal date at 15 May for the following year. Book your appointment on or after the first day of the window, and leave enough time before the expiry day to arrange any repairs the test might identify.
Why does testing more than a month early change the date?
Testing before the window opens is allowed, but the renewal date moves. The new expiry becomes one year minus a day from the pass date, so the day you test decides the new deadline. GOV.UK’s example is a pass on 14 April, which gives an expiry of 13 April the following year. Early testing therefore has a cost: you finish the test sooner, but you give up the remaining time on the current certificate. Before booking early, work out the new expiry date and put it in your diary, rather than assuming the old date still applies.
Does Northern Ireland change the dates?
The early-test rule does not apply if the last MOT was in Northern Ireland and the next test takes place in Great Britain. In that case the renewal date is based on the Great Britain test date, so the calendar works differently from the window described above. GOV.UK also notes that Northern Ireland has different rules and processes for vehicles registered there. If your car is registered in Northern Ireland, check the GOV.UK guidance for that territory before booking, rather than applying Great Britain timings to it.
How do you plan the next test step by step?
Start by finding the expiry date in the MOT history service, because that record is the reference for everything else. Next, count back one month from the expiry date and then move forward one day. That gives the first day on which a test will keep your renewal date. Set a reminder for a few days before that day, so you have time to book a test centre appointment inside the window. After the test, check the new certificate and note the new expiry date in your diary and on your phone. If you are unsure which day counts, contact a test centre and give them the expiry date from the history record, so they can confirm the booking is in the correct window.
What happens if your MOT has expired?
Once the MOT has run out, you cannot drive or park the vehicle on the road. GOV.UK states that you can be fined up to £1,000 for driving a vehicle without a valid MOT, and that you may be prosecuted if caught. The rules allow two exceptions for driving: a journey to or from a place where the vehicle will be repaired, and a journey to a pre-arranged MOT test. Keep either journey as short and direct as possible, carry the booking confirmation, and do not drive a car you know has a serious fault. For any other trip, arrange recovery or transport instead.
Because the early-test rule only covers tests taken before expiry, a test after the date has passed produces a certificate whose new expiry is set from the pass date. Confirm the exact date on the certificate you receive, and check the MOT history afterwards to be sure the record matches.
What should you do if the car failed its test?
A failed test is a different situation from an expired certificate. Read the test report, which lists the reasons for failure, and check current GOV.UK guidance on what a failed vehicle may be driven to before moving it. If the reported defects affect braking, steering, lights or tyres, treat the car as unsafe until a qualified repairer has fixed and checked them. If you are not certain whether a journey is allowed, arrange transport rather than taking the risk.
Frequently asked questions
Does the MOT history show safety recalls?
Yes, according to GOV.UK the MOT history can show possible safety recall information, depending on the manufacturer. For a full and current picture, contact the manufacturer or a franchised dealer for the make of your car.
Can I renew vehicle tax if my MOT has expired?
No. GOV.UK states that vehicle tax cannot be renewed while the MOT has run out. If the car will not be used on the road, register it as off the road (SORN) so that you are not left with tax due on a vehicle you cannot drive.
Does an expired MOT affect my car insurance?
GOV.UK covers the MOT rules, not insurance policies. Contact your insurer before driving or making a claim if your MOT has run out, and ask what the policy says about the vehicle’s roadworthiness.
