In the UK, you can take your MOT up to one month minus one day before your current certificate expires to keep the same renewal date next year. Testing earlier than that resets the expiry to one year from the new test date, potentially losing valid MOT time. This rule comes straight from the Driver and Vehicle Standards Agency (DVSA) guidelines.

Booking Window Explained

Imagine your MOT expires on 15 July 2026 —the earliest test date without shifting your renewal is 16 June 2026.

  • Your new MOT would still expire on 15 July 2027.
  • Book it on 14 June 2026? New expiry becomes **13 JuneIn the UK, you can get an MOT up to one month minus one day before your current certificate expires while keeping the same renewal date next year. Testing earlier resets the expiry to one year from the new test date, potentially losing valid time on your old MOT. This rule, set by the Driver and Vehicle Standards Agency (DVSA), helps drivers plan ahead without penalties.

Booking Window Explained

The "early MOT window" is straightforward: calculate 28 days before expiry (one month minus one day).
Example : MOT expires 15 July 2026? Earliest test date is 17 June 2026, with new expiry still 15 July 2027.

If you test on 16 June instead, expiry shifts to 15 June 2027—you forfeit that one day.

Why Book Early?

Garages get slammed in peak months like March, April, September, and October, so slots vanish fast. Many drivers book months ahead but time the actual test for the window. Centers like An Tyres let you reserve early and adjust later, plus offer free pre-MOT checks to spot issues (e.g., lights fail 29.6% of tests).

Real Driver Experiences

Forum chatter on Reddit echoes the rule: "Book a month early to keep the date—my bike's April expiry means testing post-March 2nd". Others warn of busy seasons: "Booked in January for April slot; no regrets". Trending tip: Use GOV.UK's MOT checker for reminders amid 2026's rising test volumes.

Key Rules & Risks

  • First MOT : Now at 4 years for new cars (extended from 3 in recent DVSA update).
  • No grace period : Post-expiry driving risks £1,000 fines, points, or vehicle clamp.
  • Booking hacks :
    1. Check expiry via GOV.UK or apps.
    2. Pre-check tyres, brakes, lights (top fail reasons).
3. Shop around—tests cost ~£55 max.
