My wife too our car which had perfectly aligned headlights for an MOT at Folkestone Autocentre. The tester adjusted the headlights unnecessarily without consulting my wife and charged her £20. The reason given for the adjustment was that they were low and the adjustment was necessary for the car to pass the MOT. As soon as I drove the car at night it was obvious that they had been set high and were dazzling other drivers. When I took the car back to the autocentre and informed the Manager that they were set high he stated that they must be correctly set as as they were checked using their equipment. I suggested that the headlights were probably aligned with the adjuster switch not set to zero and was told that the mechanic would have checked this. When I stated that the headlamps alignment had been satisfactory before the MOT and that nothing had happened to cause a misalignment I was told that they gradually lower during normal driving. Eventually our car was booked in for a headlamp alignment recheck and they were found set too high and were re-adjusted. We were not offered an apology or a refund. Our cars headlights are now set lower than they were before the MOT. We wish they had not been interfered with, and will not be using Halfords again.
