UK Designated Airports
 

Not sure if this post should be here or the Biz GA thread, apologies if wrong.

I'm trying to find the official list of UK designated airports for customs. I know the GAR lists them and there are Police / Terrorism & Customs designations. Some have one or other, some have both.

I understand the "designated" bit is the legal reference. I have checked the Air Nav order & the CEMA, both have references but no list.

Any clues as to where the official legal act or official reference is that lists designated airports?

Thanks
