No its not fine

I have checked the info on the MOT site and they have issued the MOT a month too early. As long as you have the MOT done within a calendar month of the expry date of the last MOT then you get the 13 months. It was taken in on 27th April but was due to run out on 26th May that was within that time.
Going to ring them first thing and see what they say. They could argue that the old certificate wasnt taken in at the time of testing but it was. Because its all computer now I'm not sure of they will correct this or not. I'm really angry about it
When I had the MOT the computer was down and they couldnt issue a certificate but gave a duplicate one which I had to take back later to get the real one. I just did not nitice the dates at the time as I've been so busy
