Hi, welcome to Just answer, my name is Ross. i will help with your question
Unfortunately, there is no permit you can get for the temporary use of a non roadworthy car on the public highway, If the car was to be used on the road, it needs to have a current MOT certificate and road tax, the MOT is needed to obtain the road tax, and to insure the car for road use.
The only way around this would be to get an MOT on the car and make the necessary modifications to conform to regulations.
This is a shame but suspected this was the case
thanks for your time
No problem, sorry i cant be of more help with this, good luck with your wedding.
