Well, electricity is more expensive than gas, that’s for sure but you may very well save on servicing and repairs. Before deciding to change to an electric boiler, you will need to check the maximum load that your circuit board can safely manage; otherwise it will trip out regularly. It’s possible to have an 80 or 100 amp fuse fitted into UK homes, but first, you must consult a qualified electrical engineer who will give advice before you invest in an electric boiler.
