If you join a local track you shouldn't have any issues doing a "track day" some are even open every day for such activity, like whilton mill in northants for example.
They do not usually do safety checks on open days as they are not responsible for issues, but some will do a visual inspection, check brakes work and check your safety equipment.
Used to race 125 and 250 long circuit and short circuit, its a lot of fun so I have a lot of experience in the sport.
