Hi Pawel,
You don't say where in London you are, its kind of a big place
If you're on the Northern edge or don't mind alittle drive we are pretty well sorted for the rec/tech and rebreather diver at our club-
www.hugsac.org.uk
We have members from all over the South East (Essex, Oxfordshire, Bedfordshire, Hertfordshire and Luxembourg!...)
Most diving OC Nitrox and Trimix but also 3 Inspiration/Evo Vision, 2 Classic KISS and 1 'Boris diver, with a couple more people considering the switch. Certainly there is almost always a CCR buddy on every trip.
Visiting divers always welcome... and we have trip spaces to fill! (plug plug...)
Okay, enough sales pitch- happy hunting, there are lots of London Clubs, try-
