just paid our electricity bill for exactly one month, came to just over £300.
The house is electrically heated, as is the cooking etc - no gas.
The house is 4 years old and detached. we have the heating on for a couple of hours in the morning and evening, the house isn't exactly warm and we don't have it set high. we generally have hot food in the evening, as do our two housemates, so 2 lots of cooking for ~20 mins a day each.
£300 sounds a lot for energy, or is it?
