Its actually really easy to fit off a cold water feed for the washing machine. Get a Y-splitter from Wickes and tap kit, take off washing machine pipe, fit splitter, replace washing machine pipe, add tape pipe to other feed, screw tap to wall, and screw feed pipe to tap. Off you go, honestly took me about as long to do that as it used to take me to get the tap adapter on the old tap! And it used to pop off all the time!
