MOT reminders that arrive before it is too late
How to know when your MOT is due, how early you can test without losing days, and what happens if you leave it too late.
How do I know when my MOT is due?
Three ways, and none of them involve remembering:
- Look at the certificate. An MOT lasts twelve months from the test, or twelve months from the expiry of the old one if you tested it early.
- Check it online. Type the registration into GOV.UK's MOT history service, or into My Cars App, and you get the expiry date in seconds. You do not have to own the vehicle.
- Be told. Set a reminder so the question never comes up again.
What happens if you drive without an MOT
You can be fined up to £1,000 for driving a vehicle without a valid MOT. That is DVSA's own figure, on GOV.UK.
There are only two exceptions. You may drive to or from a garage for repairs, and you may drive to a pre-arranged MOT test. Nothing else. And an expired MOT can affect your insurance — whether it does depends on your policy, so ask your insurer rather than assume.
The part people miss is that nobody stops you. There is no dashboard light, no letter from DVSA the day it expires, and the car drives exactly as it did the day before. It is the easiest of all the motoring dates to lose track of, which is precisely why it is worth automating.
Testing early without losing the days you have left
You can have a vehicle tested up to a month minus a day before its MOT runs out and keep the same renewal date. If it expires on 15 May, the earliest you can test and still keep 15 May is 16 April.
Test earlier than that and the anniversary moves — the new certificate runs a year from the day of the test, and the days in between are gone. Do that three weeks early every year and you have quietly given away most of a month over a decade.
So the month-minus-a-day window is the one that matters. Long enough to book somewhere convenient, short enough that you keep the date you already had.
Why leaving it to the week it expires goes wrong
Remembering on the day it expires is already too late, and not for the reason people expect. The problem is not the paperwork. It is that a garage has to have a slot.
If the one down the road cannot fit you in until the middle of next week, the car is off the road until then. Once the certificate has expired you may only drive to a test you have already booked, or to a garage for repairs. The commute, the school run, the weekly shop — all of it stops, over an appointment you could have made a month ago.
And a test can fail. Then it is parts, and parts have to arrive, and the garage has to fit you back in. A month's notice absorbs all of that comfortably. Two days' notice absorbs none of it.
That is the entire argument for being told early. Not the fine, not the paperwork — simply having enough room to book a convenient time, fix whatever it fails on, and carry on driving.
Reminders that do not depend on us
My Cars App hands the reminder to your phone's own alarm scheduler, then gets out of the way. Nothing runs in the background, no server holds a list of your vehicles, and if we disappeared tomorrow the reminders already on your phone would still go off.

Every test DVSA holds for the vehicle, pass or fail, with the mileage recorded at each one and any advisories the tester left.
