What happens if my vehicle fails the MOT? Can Horners help? The simple answer is yes! If your vehicle should not meet the standards required to be issued with a MOT test certificate we will gladly prepare a no-obligation quote for any repairs that may be required. Upon your approval of the repair quotation, we will commence work as soon as possible, In most cases MOT repair work will be carried out the same day. On completion, a retest will be carried out (all old parts will be retained for your inspection until the car has been collected).
