Jey'sus' that seems a lot.
About 10kw/h a day in winter, 8kw/h a day in summer. We have a 3 bed terraced house of 1979 vintage.
That's with me working from home on the computer all day too, and a pond pump keeping the fish happy 24/7 (about 80W constant on that).
My heating and cooking is all gas though, apart from a convector I use to top up the heat in my study whilst I am working and all the lighting that matters is CFL/LED.
Do you do a lot of cloths washing? The drier is the thing that really pushes up the bills for us. We try to avoid it.. but this winter..... Drying inside without it is not an option it just causes too much damp.
