Hi there, shows as a first post, but been on the forums a while back, the guys over in the BR forum helped me out a lot but have lost all login and email info from then so re-registered.

Anyways, moved house a little while back, saw the supplier was eon, provided details and they got back to me. Saw the tariff was a little high so decided to contact my old supplier Atlantic and sign back up with them. Got a call from EON yesterday asking why i'd switched, explained atlantic were cheaper and suddenly eon offered a cheaper tariff and so on.

But i'm going off topic. I need to know how to calculate my gas usage. I've trawled through many threads on here and have ended up more confused. I've checked my meter, it has 4 numbers, then a few red numbers, a little dial on the end and the reading is in ft3. How do I go about converting these numbers to my gas bill.

I'm panicking a little because we had a supplementary bill come through from the last tenants for a few days before we moved in, they'd only used something like 6 units on the meter and the charge was around £13. We've used in excess of 100 units in the last 7 weeks.

Our last home we used the gas almost constantly all day/evening, paid £23 month DD and only ever had to make up around £10 at the end of the quarter. We've hardly used the gas here and the consumption is massive.

Any and all help is greatly appreciated, thanks!

Multiply the difference between readings of just the black numbers by 32. That converts the gas units to kWh.

6 units costing £13 sounds about right - 13/(6*32) = 13/192 = 6.8p per kWh. This average cost will fall a bit if you work it out over a full quarter because the tier 2 price will be a lot less than 6.8p - at least one-third less. Look up the tier 2 price on the bill.

Is it just as simple as multiplying by 32, i thought there was a lot more to it than that, like 3/4 steps, or is this just the straight forward method?

If you want an accurate calculation, enter your figures here as the calorific value does vary region to region.

This site thinks i'm with british gas though, does that make a difference? Also i think the calorific value for eon is 39.1...is that correct? It shows as 40 on this site?

That site doesn't think that you are with British Gas! The gas in the pipeline is exactly the same gas regardless of your supplier but the calorific value does vary from region to region. Did you enter your post code?

I entered the postcode, got the kwh result on the next page, then I clicked on the link to see how it was calculated. It gave me a list of different suppliers, when I clicked on the link for my own it said i'm supplied by BG and gave me incorrect tarriff readings. Guess it just makes a poor assumption from the postcode?
