£120 per four weeks is not high for this past winter. I take it this does include some heating?

If you really are just using it for one hour per day, have you checked that you have an imperial meter and are being billed for an imperial meter? What do you get when you divide the kWhs by the meter units used - if the meter is metric, this sum should be about 11 or 11.2; if imperial about 31 or 32.

If you are at work you probably should not use a timer - just switch it on when you come home to avoid heating an empty home. And unless you have no insulation whatsoever there is little point just having the heating on for one hour - stick it on for two or three hours - the latter hours will not use as much gas.

Hi - I'm new to this so bare with me. I have just got our gas bill which is over £600 - I just can't believe its so high - how do I know if the meter is working properly? I've checked the readings and they are correct but don't believe we have used that much gas especially when we are at work and it is on a timer and we don't use it for hot water only 1 hour a day. What do i do? We contacted BG and have arranged a payment plan but based on this it would seemm that we are using about £30 a week in Gas.
