I use a Peterson tank like this one:
London should have some sort of darkroom photography courses, that you may want to enroll in. I took one about seven years ago to see if I wanted to pursue developing at home.The place had a state of the art darkroom, with areas for cutting film, dust proof closets for hanging film to dry, proper "dark" rooms for changing the film into the developing tanks and so on.
The best part for me was the dry printing. Using the enlarger & filters then putting the paper into the printer and a couple minutes later you have a beautiful 8x10 b&w print.
You were allowed an "x" number of hours a week of "off hours" darkroom access, so I would go in Sunday when no classes were on and print a whole bunch of stuff that I had shot over the years just to get prints. (I had to supply the paper of course)
