It really helps if you understand your energy bill as this will help you to see where you can save money. Unfortunately, every energy bill is laid out differently, but don’t despair.  The Which? website provides a handy list of the energy companies’ guides to their own bills: 

Your tariff

The tariff is made up of two sections:

  • the price per unit of energy
  • any standing charge that is levied irrespective of how much energy you use.

The tariff that you are currently on should be clearly displayed on your statement. You will need this if you wish to put your current details into a price comparison website.

Your meter readings

On the statement, your meter readings are usually followed by one of three letters

  • A (for Actual) - an official meter reader has taken the reading. 
  • E (for Estimated) - the reading is an estimate based on previous consumption patterns. 
  • C (for customer) - you have supplied a reading yourself.  It’s a good idea to supply a reading yourself on a regular basis to avoid receiving  estimated readings which can result in your being in credit or debit until an actual reading is taken (this is required every two years). 
Your charges

What you owe depends on a combination of how much energy you used in the previous period, any standing charges that apply and any credit balance you already have.  You may also receive discounts (e.g. for dual fuel) which should be shown here.

You can claim your money back ( if your account is significantly in credit.

Your usage summary

Each statement provides details of how much energy you used measured in units of kilowatt-hours (kWh).  It also projects your usage and costs over the next 12 months. Use this data to understand how your consumption changes and on the energy comparison websites.
