You're not all electric. As the most expensive part of a domestic energy bill is heating and hot water, your electric bill seems a bit high but as you do use for occasional heating its probably the best you can get at the moment.
How do you get your hot water?
I live in a 3-bed bungalow. I have electricity for lights and sockets, gas for central heating. My last electricity bill was for the period 28/04/22 to 22/07/22, and it was £160.39. That equals £53.46 per month.
