I need a cooker hood to be fitted onto the wall, with the hose/outlet bit to be put up through the ceiling/behind the wall and connected to the outlet for the current extractor fan. It looks like it'll need to be hardwired in, so can anyone advise as to whether a handyman type person could do all of this or whether it needs to be a qualified electrician? Ex used to deal with all of this sort of thing so feeling a bit overwhelmed!
