Unit prices of electric and gas?

Question

is there a site that gives you the price per unit from all the energy companys but not a comparison site for switching. some thing wrong with my bills but unable to see why. is it possible that energy companies charge differently depending on post code. as an example I went on holiday for two weeks recently and took readings just before and soon as we came back. turned everything that i could off yet was still using more electric than a colleague of mine who was at home. electric company thought this was ok. I don't see this being poosible.

we average over last six months 15 units a day

Answer 1

You may wish to do an energy audit:

These can range from answering questions at a web site

"What is the temperature setting on your water heater?"

to experts using thermal-infrared camera's and leak-testing your house or apartment.

Answer 2

Did you switch off at the mains? If you did then your meter is obviously faulty.

If you didn't then you obviously left something on like a burglar alarm etc.

Don't know about a comparison site, but would like to know about it if there is.
