Wow - some really helpful responses here which I am very grateful for and all in favour of going with the PPL.
Biggin would be my local airport and where I did my training before - Redhill would also be feasible. Kenley for gliding is also a very short distance for me and not something I'd considered.
I had also not considered finding flying buddies from the flying itself that's a very important point.
Cenus said I could do the IR(R) (I'm assuming the (R) bit is a restriction) - I will look into this - I'm almost certain the CAA said I could only do VFR. I don't think I could afford an IR but an IMC rating I would certainly like to have in the UK for both safety and the enjoyment of it.
Many thanks again all for the responses - I think I need to go book a trial lesson and rekindle the fire ...
