Hi Thomas, If you're replacing an old hob with a new one of the same wattage, somewhere between £50-£80, depending where about do you live (in central London could be even more) If it's a new installation, then you'll need an electrician to assess how the cable is going to be run from the consumer unit to the hob, how thick the cable must be (depending of the load and the length of the run), if there's spare MCBs in the consumer unit, if the walls needs channeling to run the cable, etc.. Depending on these factors, the price could get up to £200-£300.
