You can book an MOT whenever you would like, but it makes sense to do so in the final month before your MOT certificate expires so you get the greatest amount of time for your money.

That’s because tests carried out a month (minus a day) before your current certificate expires keep the same expiry date. If you get it done before this, the expiry date will move back accordingly, and you’ll lose out on days of certification you have paid for.

For example, if your current MOT certificate runs out on 15 September , the earliest you can have it re-tested and retain the same renewal date in the following year is 16 August.
