Your electricity and gas bill explained

Nobody particularly likes their electricity and gas bill. But it's worse when it's hard to understand. We make ours as straightforward as possible – and we've created this guide to explain each section of it.

1. Current Balance

This is the current balance of your account, for each energy type. You will also find the period the bill covers for each of your fuels.

If you pay by cash, cheque or bank transfer, this tells you the amount you need to pay if you have a debit balance. If your account is in credit, you may be due a refund – please contact us to discuss.

If you pay by monthly Direct Debit, you don't need to do anything.  However, if you are building up a large debit or credit balance, take a meter reading and contact us to discuss. 

If you pay by quarterly Direct Debit and you have a debit balance, this is the amount we will request from your bank account on the agreed date.  If you are in credit, you may be due a refund – please contact us to discuss.

2. This Bill

This shows the electricity and gas charges for the period of this bill.

3. Your Account Summary

This shows all the financial transactions that have taken place on your account since your last bill. It includes the previous balance of your account, the amount of this bill, and any payments and refunds that have been made, all of which contribute to the current balance of your account which is shown here.

4. 24 Hour Emergencies

Electricity

If there’s a power cut, this is the number to report it. You’ll get through to your local Network Operator who’s responsible for the local network that delivers power to your home (or business). We don’t operate the local network.

Gas

If you are concerned about a potential gas leak, this is the number of the National Gas Emergency Service which you need to call to report it.

You can find more information about what to do if you experience a power cut or gas leak on our power cuts page.

5. Account detail

Here you will see your Ecotricity account number, the date this bill was produced and your supply address.

6. Could you pay less?

We have estimated your annual cost using your consumption history and our current prices. If we don’t have a full history of meter reads, we may base this on industry estimates. Using this data, we look to see if you’d benefit from being on any of our other tariffs. 

If you would be better off on a different tariff we will also tell you how much you could save. Remember, this is based on historic information, so if your circumstances change, this may change. Give us a call and we’ll discuss your options. 

We’re obliged by Ofgem to remind you that you can switch to a different supplier – if you are thinking about doing this, please get in touch so we can discuss why you are thinking of leaving.

7. Your usage

Here you will see a graph showing your Electricity and Gas usage for the period covered by this bill and for the corresponding bill from the same time last year. The accuracy of this information will depend on how many actual meter readings we hold.

8. Your meter readings

These are readings we have used to produce this bill. For electricity and gas you will see:

  • Your meter ID - this should be visible on the front of your meter
  • A previous meter reading (which is from the date of the start of the billing period shown at the top of the bill)
  • A current meter reading (which is from the date of the end of the billing period)
  • The total number of units used (which is the sum of deducting the previous reading from the current one).

The meter readings are annotated to show where the read came from. Here's a list of these annotations with a brief explanation:

Actual - a reading supplied to us by another supplier
Customer - a read taken by an occupier (or person on behalf of the occupier) of the property
Estimated - a reading estimated based on your previous consumption history.  We prefer to send you bills based on actual reads, so please take and send us your own readings regularly
Agent - a reading taken by an official meter reading company
Special - a reading taken by our agent during a special visit
Final - a final read for a meter that was removed
Initial - a first reading from a new meter
Prepayment - a reading received for a prepayment meter
Modified - a reading that has been modified by our agent
COT - a reading for a change of occupier in your property

If you have any questions about the type of meter you have or how to read it, just call our Customer Service Team on 0345 7 555 200.

9. How we calculated your bill

This is a summary of how your bill has been calculated. This shows the total number of kilowatt hours (or kWh for short) you have used and the price per kWh at which you have been charged. This will also show the details of any price changes that may have occurred within the period covered by this bill, along with any discounts and the VAT. You will have a calculation section for your electricity and gas.

10. Gas unit conversion

As gas meters record the volume of gas used, we have to use an equation to convert this volume into kilowatt hours used.  Every supplier uses the same equation.

Metric conversion factor - if you have an imperial meter, you will see a metric conversion factor of 2.83.  We multiply the units recorded by the meter by this to calculate cubic meters used.  If you have a metric meter, we don’t need to do this step so you will just see a 1 here.

Calorific value - the quality of gas supplied to your property varies in quality on a daily basis.  To account for this, we adjust your consumption by multiplying the volume by a calorific value supplied to us by National Grid.

Volume correction factor – this adjusts the volume used for temperature and pressure.kWh conversion factor – this is a final calculation to convert the volume of gas to kWh which is what our prices are based on.kWhs used – the figure calculated here is carried up to the “How we calculated your bill” section.

We know it’s a bit complicated so do just give us a call if you want us to explain further on 0345 555 7 200.

11. Meter Point Numbers

These numbers (MPAN for electricity, MPRN for gas) are unique to your electricity and gas supply and identify you within the electricity and gas industry. This isn’t the same as your meter serial numbers, which are printed on your meters.

12. About Your Tariff

Here you can find your current tariff and payment method.We also show your annual consumption, which is based on your consumption history. If we don’t have a full history of meter reads, we may base this on estimates provided by the industry.

13. About Your TCR

The TCR is a numerical value which sets out the unit price (p/kWh) for a customer with a typical annual electricity consumption of 3,100 kWh or annual gas consumption of 12,500 kWh. It takes into account the price, tie-ins, discounts, exemptions and bundled products.

The TCR is not based on your personal consumption and is not an actual price. You can ask us and any other energy supplier to send you a copy of a TCR in relation to any tariff and you can use these values to compare the various offers available in the market. Please note, however, that a TCR is a price-only index, and does not account for any other supplier attributes such as fuel mix or customer service rating. TCR does not currently apply to an Economy 7 tariff.
