I'm looking to change my current built in gas oven and hob to electric. I'm getting very confused as I've been told that I can't have an electric hob due to not being able to get new wiring in without destroying my kitchen. They have said it's possible to get an electric oven in though. Does that make sense? They are going to have to hard wire in the oven...so why is the hob different? There's currently just the gas connection and a double plug socket.
