MOT Testing

An MOT test checks that your vehicle meets a variety of safety and environment standards and is required by law annually if your vehicle is over 3 years old.

At THM Sport all of our technicians are qualified to perform MOT testing and as such gives us a large capacity for both walk in and pre-booked appointments.

Our MOT tests are priced at a competitive fee of £49 for Class 4 vehciles and £58.50 for Class 7 vehicles. We offer a free retest and partial examination with 10 days of a failed MOT test.

You can get an MOT up to a month (minus 1 day) before it runs out and keep the same renewal date.

You can MOT your vehicle at any time outside of the 1 month before but the expiry date will be 1 year from the date of the new test. This is sometimes useful for example if you wish to sell your car, it can provide a good selling point.
