There is a lesson to be learned here , get your MOT Booked in a month before it's expiry date , then if it passes great you get 13 months MOT , If it fails as in your case you are left with one months MOT to get the job done at your leaisure . I don't know why everyone leaves it to the last day to get their MOT done , IT's very rare to write out a MOT for 13 months time ... !
