Brilliant!! An hour on the phone to BG to get this answer but the adviser stil couldn't tell me! All I wanted to know was how they calculated how many kwh's were charged in tier 1 and how many in Tier 2.. It's different on every statement and now I know why. Many thanks, however,do you have any idea how to calculate how many kwh's I will be charged for in each for tier for electric. This formula doesn't appear to work but I have Economy 7.... 2 Tiers and a night reading!! Thanks Clive

Could you explain step 2? I don't get, why the conversion is 2.83. According to this page ( and my knowledge feet is a smaller than meter, so it should be 0.0283. Gets me really confused.

Hi Jakub, This direct from British Gas, this is the standard calculations template, a copy of which I received after numerous requests and comes from, I believe, British gas' back office and is used by British gas' billing staff. "If the customer has a 4 dial (imperial) meter, you need to convert the imperial units (HCF) to metric units (M3). If the customer has a metric meter you can leave this step out and move straight onto Step 3. Imperial units (HCF) x 2.83 = Metric units (M3)" Took a while to find the original message, but got there in the end. Hope this helps

Thanks for that, just waiting for British Gas to get back to me to confirm... Hope this doesn't open a can of worms!

Confirmation from British Gas; "Yes we multiply the number of units used (in hundreds of cubic feet) by 2.83" So the formula I posted here is used and accurate for British gas billing...
