Well it’s that time of year again and need to renew my Class 1 medical as depending on age is only lasts a maximum of one year. Your initial Class 1 which is required for commercial work must take place at the CAA building at Gatwick. After that you are able to renew at you local Aeromedical Examiner (AME), below is a link which is useful at finding where your nearest one is:

If you are training for a Private Pilots License (PPL) you do not require a Class 1 and a Class 2 is fine. Your initial Class 2 can be conducted at your local AME (she link above) and is valid for more than a year depending on age.
The link below is to the CAA medical section of the website and gives you all the information you need:
