Check out the CAA website on this under SRG/ What's new. Basically it says that if you do not manage to unfreeze a UK ATPL by June 2002 (1500 hours, 100 night etc) then you will have to meet JAA requirements to unfreeze it (1500 hours, 500 in multi-crew a/c). You can of course still have a UK CPL. Or that's how I read it anyway.
