You need to get your medical done by an approved practioner. There is one located permanently at the place where the DiamondStars fly. Drop me a PM for details, and have your cheque / cash ready (you soon learn that this flying lark is a great way to hand over lots of money to lots of people
)
Your club / school will also have details of their local specialist, or use the CAA search page

Note that you need to have passed your medical *AND* the Air Law exam before going solo. Book the medical asap as there could be a waiting list.
If you have a prescription for glasses / contact lenses you must also obtain that from your opticians and take it along - the AME (the doc.) will tell you what he/she wants on the opticians report.
At least you get a decent check up and your own CAA reference number.
If you are only looking for PPLing, a Class II medical will suffice. If you want to progress to CPL etc. you will need a Class I, which is more expensive £435 v £160 and you have to go to Gatwick to undertake it.
