Check out the back of Flyer etc; there is a group flying an ex-RAF Jet Provost that may do pleasure rides.
If you want to fly weird & wonderful ones - head East or West or South
The Russians have the MiG29 flights at Zhukovsky. The Yanks have loads of options including T-38s in Florida. There is also a guy called Mike Beachyhead who has Lightnings, Hunters, Buccaneers etc in South Africa.
In all cases, more important that flying skill (for pleasure rides) is MONEY!! A one hour ride in a Starfighter at Williams Arizona costs $1800!!
Have fun!!
(PS It is worth the effort - I managed to blag a ride in a Hawk at my old job - biggest smile I ever had - adrenalin took 4 days to subside!!)
