You can MOT a car up to one month minus one day before your current MOT expires and still keep the same renewal date for next year in the UK.

Quick Scoop

  • If your MOT expires on 15 June, you can do the test from 16 May and your new MOT will still run to 15 June the following year.
  • Do it earlier than that (for example 2–3 months early) and you can still get a test, but your new expiry date will be 12 months from the day of that early test, so you “lose” the overlap.
  • Brand‑new cars usually need their first MOT at 3 years from first registration in Great Britain (4 years in Northern Ireland).

Why people do it early

  • To avoid last‑minute rush and fully booked garages, especially around March and September when lots of cars come due.
  • To give themselves time to fix fails or advisories before the current MOT actually runs out, so they’re not stuck off the road.

First MOT versus later MOTs

  • First MOT: must be done before the 3‑year (or 4‑year in NI) deadline; there isn’t the same “carry over” issue because there’s no existing MOT to preserve.
  • Later MOTs: aim for that “one month minus a day” window if you want maximum cover (effectively up to 13 months of MOT) without bringing the date forward every year.

Practical tip

  • Check your exact MOT due date online with your registration, then book it 2–3 weeks before that date within the allowed one‑month window for the best balance of flexibility and keeping your renewal date.
