Several clubs/schools have aerobatic and tailwheel aircraft available but, given your particular interest in those areas, I suggest you consider West London Aero Club (White Waltham) and the Tiger Club (Headcorn).
Both have a good atmosphere - although very different from each other.
WLAC has by far the best clubhouse in the UK.
The Tiger Club specialises in aeros and formation-flying. It was formed more than 50 years ago by aerobatics and air-racing enthusiasts and is well-established as the home of sport aviation in the UK. I was a member years ago and, from all I hear, it's still going strong.
