Gas Bill Calculation

Options
Hiya,

Just moved into a new house and trying to calculate my gas bill. When I moved in the meter reading was: 3913 68

Now after a half a month it is 3926 75

I'm with Atlantic for gas therefore, can someone give me rough calculation on how much would it be?

Many Thanks..

    It sounds like you have an Imperial gas meter.

    In which case you have used approx 405kWh

    If it were a Metric meter you would have used approx 145kWh

    The link below shows what type of meter you have.

  • Yes you are right it is Imperial Gas Meter.

    So how much do you think roughly the cost of 405kWh would be?

    Kindly, explain how did you workout 405kWh? and also please explain the workout of cost as well.

    Really appreciate your help.

    Thanks

    Cost depends on the tariff you are on but if you work on 3.5p per kWh you won't be far out - so around £14

    You can only work out exactly how many kWh are in a gas unit when you get your bill as the calorific value can change and thus figures for the calculation are known. The calculation is:
    (The number of units you've used) X (The metric conversion factor) X (The volume correction factor) X (The calorific value of the gas) divided by 3.6 = kWh's.

    However don't bother with that, as if you multiply the number of gas units by 31 you will be pretty accurate. Thus your 13.07* units = 405kWh

    * 3926.75 - 3913.68 = 13.07gas units
