If you don't mind travelling north to get your SEP and tailwheel done, then I would recommend Tatenhill Airfield - Approx 15nm West of East Midlands Airport - it's where I fly from!
The C152 is £127 Dual or the Warrior is £142 Dual to do your SEP.
For Tailwheel, the Decathlon is currently £148 per hour dual or £132 Solo...Good fun to play in i've been told (Not flown it myself yet), especially if you're in to your Aero's as well!
I hope this helps
