I'm a bit out of it in the UK - but I've had great experiences at Prestwick Flying Club and Leading Edge. Both very different - and Prestwick is obviously a bit of a drive - but, at 26, if you have no other commitments you'd find yourself driving down there for a 1 hr lesson and spending the rest of the day speaking with folk/learning in the club house.
Controversial, but I'd also consider doing your circuit training as part of a holiday somewhere with no landing fees (I did three or four days of circuits at Larnaca).
