How much are you paying for your gas?

i have no problems with my electricity seems very reasonable compared to other people. but my gas is a nightmare we have a combi boiler,my attic is insolated and we have double glazing. i cook by electricity, 4 people have a bath daily and ive only just started using my heating instead of my gasfire for a couple of hours in the morning and again all evening and its set to 18 and a couple of radiators are switched off, but i seem to be paying way more than other people for gas than other people i know who cook by gas and have there heating on constant, i had my metre checked and was told its fine.ive now changed gas company and it seems to be the same
