Mine has gone up a lot per KwHour due to the price of energy skyrocketing. However, I had a multi-fuel stove fitted over a year ago as I foresaw the Russian invasion of Ukraine and the impact Russian gas scarcity would have on the price of gas and electricity. Our energy supplier estimated our yearly cost would be over £6,000 (gas + electricity) but due to the stove the figure will be nearer to £2,000 per year. We are enduring some hardship though as we've turned off the central heating, electric towel rails, underfloor heating and all the radiators in the rooms we don't use very much. We are now more or less living in the one room with the wood-burner; also using it to boil a kettle and some cooking.
Part of it is being willing to adapt. We wear multiple layers of clothing in the house. In the evening this room with the computer drops down to around 10C. So I just wrap up warmly, sometimes with a coat, scarf and baseball cap. No point heating the room considering the high cost of doing so.
