We recently bought a house that has a large electric 3-oven AGA, with a gas hob and 2 additional ovens. It's huge! I have so far been only using the gas hob and the ovens I can switch on and off in a conventional way. Now, I am absolutely terrified turning the main AGA on, because it's meant to be on constantly and there is no way to estimate the cost of running it. I remember the estate agent mentioned that pre-energy crisis, it was something like £4-6 a day.
Those who have a an AGA and a smart meter, could you tell me the effect on your energy bill now and estimated for the coldest months? Is it worth turning on?
