Bathroom extractor fan and heater, exterior power point, fix flickering lights

I'm looking to have a few electrical things done around the house: 1) Install a new bathroom extractor fan. There is one installed, but it was unplugged by a previous owner. 2) Install a heater in the bathroom 3) Add an exterior power point, there's already 1 on a separate fuse but would like another 4) A set of lights flickers rapidly whenever they're on that I'd like to stop
