Yeah, I fell into that trap with my last Westfield; got the MoT due notice at 12 months after SVA, (as it was then,) with it being on a Q and me not realising, I just assumed that's what you did with Q plate cars.
I found out after mentioning to someone that I'd just done my MoT, that I didn't need to have one, and someone on here, I think possibly @pete g clarified with the DVLA that you didn't. So year two, I get in touch when the renewal notice comes through, to be told that no, I hadn't needed one, but that I was now on the system as showing MoT expired. So anyone doing a vehicle check would only see that. So basically I was then "stuck" with MoT'ing from then on in...
Except, I've been really lucky to have been able to use two exceptionally good garages over all my kit MoT's, that both understand Kits, Q plates and how they affect the test, but also to really understand kit's too. - they understand, that normally they are the only trained person to examine the car, once a year. So both garages have actually gone out of their way to examine important things for the safety and drivability of the car, regardless of whether they're normally testable items. - It's funny, the first words of the garage owner, from the place in Congleton, once he'd guided me on to the lift, were usually "Have you had the nose off?", (always was a yes, of course), the next words were usually, "well I hope you've brought your spanners to adjust the bl**** headlights, I'm not doing them for you!".
But it's always been reassuring that the car has been properly checked over, top and bottom, on a proper lift, where you've got good access and can see everything.
