Think it was Quicks Services . I used to use one in Wallasey at £25 and then shop around if work needed doing. Lot depends on if they charge a retest fee. Don't know if or what the fee is a garage has to pay to Dept Transport
I think all testing stations are monitored by VOSA for their pass and fail ratio, however they can coax unsuspecting costumers into having work done by means of advisory items.
If you disagree with your MOT test results, you'll need to discuss them with an MOT test station representative before anyone carries out repairs to the vehicle. You have the right to view why the vehicle failed. Don't be fobbed off, I once had a car fail because the 4 way flasher unit didn't work the way the tester said it ought to. I went to a local garage selling the same car and sure enough it worked the same as mine. The button needed pressing and holding 3 secs to activate. My car was then given a pass cert. Testers are not infallable so stand your ground if you feel hard done by. If you have doubts try and get someone knowledgeable to go with you if need be but don't agree to start work unless you either trust the garage or had it checked out.
Appealing against a failed test result If you want to appeal against a failed test result, then you'll need to complete an appeal form VT17 available from any MOT test station, online or by ringing VOSA on 0300 123 9000. The down side of this procedure is that you will have to pay for another test in full and upfront.
