Contrary to popular belief, you don't have to wait until your MOT is about to expire to get your car tested. You can present your car at any time for an MOT, but you only need to get a certificate once a year.
If you put your car in for its MOT in the month before your MOT is due, the test certificate will cover from the date of the test to one year after the expiry date of the current certificate. For example, if your first MOT was due to expire on 4 November 2006 and you take your car in on 15 October, the certificate would run from 15 October 2006 - 4 November 2007. If you want this extension you will need to present your old test certificate at the test station to prove that the time can be added on. This is extremely useful should you find it difficult to find the time to get your car MOT'd on or around the exact date of renewal.
