Bet you'll have fun though, as most class 4 MOT places do not have a tray for the rear wheel, so will be unable to do it.
My guess is you'll need a MOT place that has a class 3 and class 4 testers certificate even if the MOT needed is class 4.
Members of the Three Wheeler club can see a list of good garages that do class 3 MOTs and I know the one I recommended can do both classes 3 and 4, so could do a new one. TA Lingard of Berkhampstead.
