Try joining Westminster boating base. If you can prove you are competent (RYA level 2 or greater), and can handle the tides (they will want to take you out with them a few times to prove this. The Thames tides are very strong), then they might suit your needs. They also do courses which will give you your RYA level 2.
TBH I don't think you should really go sailing on the Thames without some sort of safety boat cover, just because the tides are so strong. When I learnt at Westminster, we could never sail for too long without getting washed down by the tide.
For inland sailing, Welsh Harp reservoir (nea rWembley) is a nice little place. Informal club, and they're much more likely to let you take boats out yourself after a few weeks, but obviously it's not the Thames.
...if you press it, they will come.
