Lapsed PSV licence

[666 SVT]

Does anybody know what the situation is with a lapsed PSV licence? Situation is that I passed my class 1 PSV in 1986 and spent several years in the bus and coach industry, In 1996 I left to do other work. I remember getting a letter when I was 46 saying I needed a compulsory medical but as I was no longing in that line of work I didn't bother. Question is if I wanted to try and get it back is it just a question of having the medical and asking the DVLA for the entitlement back or would I need to do the test again? Cheers.

Thanks for the replies I will see the quack about the medical and take it from there ?
