The Griphouse gym is good. They have Muay Thai, bjj, wrestling, mma. Not sure what else as I haven't been in a long time. This is their website www.thegriphouse.co.uk. Several UFC fighters train/ trained there.
Edit: here's their timetable. They don't do judo but they do bjj. http://www.thegriphouse.co.uk/whatson.html
Pretty sure they have 2 black belt coaches.
