What information is on my energy bill?
Most energy bills contain:
- Your name and address
- Your account number
- The name and contact details of your supplier
- The name of the tariff you are on
- How much gas and electricity you have used since your last bill
- Your latest meter readings. These may be estimates
- Your estimated yearly cost
- Your payment method
- The amount you need to pay
- Reference numbers for your meters
Check your details
Make sure your details are up to date. If not, you could be paying for someone else's energy.
- Your name and full address on the bill are correct
- The letter is not addressed to ‘the occupier’
- The meter reference numbers match
- The billing period only covers time you have lived in the property
If you are moving, take a meter reading:
- On the day you move out of your old home
- On the day you move into your new home
The tariff is the price you pay per unit for the gas or electricity you use.
This includes a fixed, daily standing charge.
Types of tariff
There are two main tariff types:
Your supplier may offer other tariffs too.
Your energy use
This shows a breakdown of your usage over the last period.
Bills need to show the cost of your energy for the last 12 months. Unless you have been with your supplier for less than a year.
Estimated annual cost
This predicts the cost of your energy for the next year.
It is based on what you have used in the last 12 months.
It assumes you:
- Stay on the same tariff
- Use the same amount of energy
Terms and conditions
Suppliers should explain the terms of your contract, including:
- Exit fees
- Tariff end dates
Tariff end dates
With a fixed-rate, you roll onto your provider’s standard variable rate when the tariff ends.
Early exit fees
You may need to pay an early exit fee if you want to:
- Change suppliers
- Move to a new deal
Your provider cannot charge exit fees if you switch within 49 days of your current deal ending.
How your bill is calculated
The "unit rate" is the price for each unit of gas or electricity you use.
Units are calculated as pence per kiloWatt hour (kWh).
There may be more than one unit rate on your bills. For example, day, night and weekend rates.
What does 'kWh' mean?
A kiloWatt hour is the measure used to explain how much energy you use.
Energy is measured in Watts. 1,000 watts is equal to one kiloWatt (kW).
If you use an appliance rated at 1,000 watts for one hour, you are charged for 1kWh.
Examples of appliances and their kWh energy usage:
- Electric kettle - 0.1 kWh
- Electric oven - 1.56 kWh
- Washing machine - 0.63 kWh
- LCD TV - 0.21 kWh
A standing charge applies to both gas and electricity.
- It is a fixed daily charge
- It covers the cost of your gas and electricity supply
What Credit and Debit means on your bill
- Credit (or ‘CR’) means you overpaid
- Debit (or ‘DR’) means you need to pay
