Thanks for advice
Thanks for all the advice chaps. It appears Whopity is correct.
I got through to a helpful guy in Licencing at Gatwick who advised that I needed to complete the following:
Class 1 Medical Renewal,
Form SRG1102 Application to Renew UK Licence,
Form SRG1104 Application for EASA Part-FCL Pilot Licence - Conversion of an Existing National or JAR-FCL Licence Issued by the United Kingdom.
Much appreciated.
