Your bill depends on how much energy you’ve used since your last bill and what tariff you're on. We work out how many kilowatt hours (kWh) of energy you’ve used and multiply that by your tariff rate to work out how much you owe.
I've received an estimated bill, what should I do?
If you manage your account online, you can log in and create your own bill. Just choose the meter reading option. Once you've entered your readings it will give you the option to create your bill.

Understanding your bill or statement
How can I get a paper copy of my bill?
You can download a PDF copy of your paper bill and print it off at home.
You can choose between having paper bills or paperless billing by updating your details. You'll still be able to keep your online account and get access to your bills, give meter readings, manage how we get in touch with you and every other benefit of an online account.
However, opting out of paperless billing means you may lose any paperless billing discount you're currently getting, so your bills may be higher.
What are my current energy prices?
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.
Why do you charge me VAT?
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%.
Will I get money off for having Dual Fuel?
If you're currently getting a discount for having both fuels with us, you'll get it until the end of your fixed deal.
What is the 'conversion factor'?
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.
What does 'calorific value' mean?
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.
How do you work out my gas charges?
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.
Am I entitled to any discounts?
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.
How do I make sure I only pay for the energy I have used?
When you give us a meter reading we make sure you only pay for the energy you've used. Without meter readings we have to estimate how much you've used since your last bill, which means we might charge you the wrong amount.
We'll estimate your bill when:
We haven't got meter readings close enough to when we send you your bill
We haven't got a recent meter reading for one of your meters
A price or tariff has changed since your last bill
I have had an estimated bill, how can I give you a reading?
You can give us a meter reading at any time by either logging in to your online account or by using the non-registered meter reading service.
We can only accept one reading per day so if we’ve estimated your bill today, you’ll need to wait until tomorrow to give us another reading.
If your reading is lower than the one we’ve estimated, we’ll automatically re-bill your account and generate a new bill for you.
If your reading is higher than the one we’ve estimated, we’ll give you an updated balance if you’re logged in to your account and the option to request an updated bill if you want one. If you use the non-registered process, we’ll add your new reading on to your account.
I don't understand my bill
Your bill may have been revised based on us receiving corrected readings. If you're still not sure or have a more specific question you can contact us and we'll be happy to help.
If you need help with making sense of your bill you can take a look at our jargon buster.
Why does my bill have more than one set of charges?
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.

I don't think my bill is right, what should I do?
If you've provided meter readings, or we've come out to read your meter, but your bill is still estimated, there may have been a problem with the readings. Please check your readings and provide us with another reading, this can be done online by logging into your account.
If the meter readings on your bill are right then it may be worth thinking about:
If we’ve under-estimated your bills in the past your bill will be higher as we’re charging you now, for energy you used in previous months
The time of year, as you may use more during the winter months
If there’s been a price change since your last bill
If you’ve changed anything in your home, for example new appliances
If there’s been an increase in the number of people in your home
If you’ve been doing home improvements the appliances used may increase your usage
If you still think your bill isn’t right, we’re here to help, you can contact us and we’ll be happy to go through it with you.
