# What is a M3 of Gas and how much is it?

Forumite Posts: 3 Newbie
I have moved into a 1 bedroom flat.

3 Rads + combi boilier + gas cooker.

I 1 month ive used 100 M3 on my new gas meter. I have registered with Eon and they have sent me a welcome letter but not any advice on how much my bill will be.

I heard it was 7p per kwh.

But how do I get from 100 cubic meters of gas, to kwh ?

Does anybody have a clue if im likely to be using £10 a month gas, or £30? or £50?

I am just dredding waiting 3months for a bill then it being astonishingly high, the meter seems to be using a lot of gas!

The information is usually on your gas bill. It involves the use of a calculator and something called the calorific value. This value does change from time to time so it is best to use the value shown on your gas bill.

100 cubic metres (m3) is just over 1100 kwh.
If your tariff is a no standing charge one then you pay a higher rate for the first so many kwh a year (could be something like 4572) then the rest of the kwhs are at a much lower rate. I suspect your 7p per kwh is the primary rate so the majority of those 1100kwh will be charged at lower rate than 7p, could be lower than 3p per kwh.
To be more accurate you will have to tell us the details of your tariff or post it's name.

The OP won't have a gas bill yet and is trying to budget for used gas!

:rolleyes:

100 M3 is approx 1136 kWh, however you should not be paying 7p per kWh unless it is just for the first few units used (primary units.) Normal price would be approx 3p per kWh, check your tariff on their website.

I do not know the name of the tarrif im on, nor have I recieved my first bill, im just worried that the bill is going to be huge.

Going by the default standard tarrif and the calorific value on your bill can you give me a rough estimate at what id be looking at. I know it will be different for me, but it will give me some indication...

I heard somewhere that you times the M3 by 3 to get your bill, which would be £300 for a month...whereas a friend of mine who fits heating systems said I should be using around £3 a week.... and ive no idea which one im closer to

What are my current prices?
You can find your current prices on your latest bill. If we've changed our prices since you received it, we'll have written to you to let you know.

If you haven't received a bill since joining E.ON, please refer to the registration pack sent to you when you signed up.

IF we assume that your primary units are 7p per kwh and your secondary ones are 3p, and that the threshhold value is 4572 primary units a year (380 per month)then your monthly cost will be:

1100 minus 380 = 720 @ 3p = £21.60

380 primary @ 7p = £26.60

So the cost will be £48.20

I stress that this is only approximate as we do not know anything about your tariff. Why not ring your supplier and ask, then substitute the actual figures in the above calculation.

I would not believe either of your two friends. To convert m3 to kwh you multiply by just over 11. And I am afraid that £3 a week with gas central heating is way too low, I think the average for a year is £500 to £600 ayear, although your property seems to be smaller than average so could be less than that.

If you have just moved into a property and just registered with the supplier and awaiting your bill then I think it would be a fair to assume you are just on the bog standard tariff paying quarterly unless you instructed them otherwise at the time of registration.

Whenever a property becomes vacant it will revert to standard tariff and quarterly billing, registering with a company will only usually replace "the occupier" with your name on the bill. If you want anything else (monthly DD, online billing etc) you have to ask for it
