This is a bog standard, cheap place to get your car MOTed. It takes an hour, you can book your slot online, it costs £30 (do NOT believe the published prices on the wall inside!) and is fairly no nonsense.
The customer service is pretty average, and I wouldn't try to get through on the phone - three times I called, was asked to hold and then completely forgotten about.
Top tip no. 1: It's all the way over to the right of the shops and round the corner. Don't park in the main car park, make sure you drive into the little car park outside the reception area round the corner. (You will see a handy 'reception' sign on the building).
Top tip no. 2: There is a Costa Coffee on the first floor of Next, just a few shops down that you can grab a drink and wait in while they do the MOT. read more
