Is £750 electric bill normal?

Hi, It sounds like a lot for an electricity bill, but it's hard to compare your bills with those of other people, given that there are so many variables from one house to another, and from one person's level of comfort to another, insulation/draught proofing, plus other considerations, such as electric Vs gas for cooking and hot water. One way of trying to work out whether this is a 'normal' bill or not is to do some maths. Boring, I know, but at least you'll have some idea of what might be a 'normal' bill for your household. You've mentioned that you have 2-3 radiators, used for 6 hours/day each. I'm assuming that they're electric. There should, hopefully, be some info on them somewhere about their power rating in kilowatts. Have they got thermostatic controls? Do they work and are they set to a particular temperature / rating, or are the radiators left on at full whack? In the latter case the radiators will be on all the time, pumping out heat, possibly making rooms very warm (or not in a draughty house on a cold day). I did some looking around on the internet for electric radiators, looking for wall mounted, high output models. The 'hottest' ones I could find were around 3.4kw models. A bit of maths (and I'm rubbish at maths) shows that if you had three radiators of that type, all going full blast for six hours a day each, over a month (31 days) they're using up 3.4kw x 6hours x 3 rads = 61 kwh per day between them. Over a month that's very nearly 1900kwh just for those three radiators. Octopus has a range of tariffs, so I've gone for the variable rate of 27p /kwh, which comes to £513 give or take. Portable heaters tend to be less powerful heaters, with a maximum rating of 2.5Kw. They could cost around £380 a month to run full blast for 6 hours a day. If you have an electric cooker / oven that will eat up the units with glee. An electric immersion heater for hot water will delight in gulping down your money. If you have one is it insulated/lagged? That will help prevent heat loss. Is it on all day or on a timer? Have you someone in your household who likes to take a bath, filled to the brim with lovely hot water, or who enjoys long, leisurely showers? I've done some more digging online to find the estimated cost of a 180 litre immersion heating being used for morning and evening hot water. The website reckoned that a 3kw immersion heater would need about 3 hours to heat up the water, so 6 hours per day. The daily cost would be around £5 ish, making another £150 ish a month. Other commentators have suggested that you might be being charged for electricity that's being diverted elsewhere. Such things are not unknown. The tenants of a house not far from me couldn't understand their high electricity bills, until they had a knock on the door during a power cut. The 'garage' at the end of the back garden had been converted into living accommodation, let to a completely unrelated tenant. He knocked to ask why there was no power. He had been getting free electricity, generously and unknowingly paid for by the tenants in the main house. So, it is just possible. It's also possible that there's a fault with the meter. Sometimes they're faulty and don't give accurate readings. My advice? Do some maths first, then you'll have an idea of how much your bills could be. Then, if things look wrong, get in touch with your energy supplier...and good luck!
