It’s the UK standard to calculate energy in kilo Watt hours (kWh)*. To work out your gas bill, convert the usage from your meter into kWh, here's how we do it:

1. If you have a meter that measures in hundreds of cubic feet (hcf): We take the amount of gas used, shown as 'hcf' on your bill and we multiply this by 2.83 to convert the figure in to cubic metres (m³).

If you have a meter that measures in cubic metres (m3): We take the amount of gas used, shown with 'm³' on the front of your bill.

You’ll be able to tell which type of meter you have by checking the number of digits that make up your meter reading.

Imperial Meters will have four digit readings, not counting any numbers in red or after the decimal point and are measured in cubic feet or ‘hcf’.

Metric Meters will have five or six digit readings, again, not including any numbers in red or after the decimal point and are measured in cubic meters or ‘m3’.

2. We then multiply this figure by a conversion factor of 1.02264, then by the calorific value. Calorific values vary; you can find the calorific value we’ve used for your meter under the readings on your bill.

3. Next, we divide this figure by 3.6 to show your usage in kWh.

4. Finally, we multiply your usage in kWh by your unit prices to work out your gas charge.

*By law, ‘The Gas (Calculation of Thermal Energy) Regulations 1996’, we have to send you bills for the energy you use. Your meter measures the amount of gas (volume) that passes through the meter. We use this method to work out the energy from the volume.

If you're currently getting a discount for having both fuels with us, you'll get it until the end of your fixed deal.

You can find your current prices on your latest energy bill. Please note that these prices don't include VAT, we add this on separately. You can view your latest bill using your online account. For more information on how to register or the benefits of managing your account online, click here.

VAT is Value Added Tax and it's charged on most goods and services in the UK. The government decide how much VAT should be. VAT on energy is charged at the reduced rate of 5% whilst most other goods and services are at 20%.

The gas conversion factor takes account of differences in temperature and pressure. It's always 1.02264 for all suppliers, and on all bills/statements. 

Calorific value is a measure of how much heat the gas creates when it burns. You could use this as a measure of the quality of the gas.

There are a few factors that affect the calorific value. Gas delivered to homes near the point where it comes ashore contains a different level of moisture than the gas that's used further inland. Weather changes can have an affect too. Moisture in gas affects its performance, and calorific value is there to ensure that gas is charged fairly in relation to how much energy is obtained from it.

Calorific values are tested continuously at various points throughout the National Grid gas network.

Depending on your tariff and how you choose to pay, you might be able to save money.

If you choose to pay by Direct Debit, we may reduce your prices instead of discounting your bill. If you stop paying by Direct Debit or miss payments your prices may increase.

If there's been a change to your energy prices, or if you've switched energy products since your last bill, the charges on your latest bill will be split to reflect this.
