...and do them away from the airfield.
And where exactly would that be?
AFAIK, the UK has the same 500ft rule than the rest of the world. And with the license gone, the best practice in forced landings seems rather useless to me.
Mind you, even as an instructor I am only allowed to descend below 500ft for a PFL if my student has no license yet. Once he has been issued his PPL, 500ft is the lowest I am allowed to let him descend. I don't know how it is in the UK, but here in Germany you can be 100 percent certain that somebody will write down your registration and call the police. An instructor colleague of mine once made a PFL over a gliding site (not in use at the time) with a PPL holder during one of these JAR-FCL mandatory training flights and got prompty reported and fined for that...
