You can freely receive "general reception" transmissions. This includes commercial and BBC radio stations, etc.
Listening to any other kind of transmission, including emergency services, ATC, etc. is illegal unless you have an applicable licence.
All this is explained on the Ofcom Website. Stick "Ofcom receive-only" into Google.
Your FRTOL only entitles you to operate a fixed installation in an aircraft. This is covered in LASORS section B.
