Understanding your gas and electricity bills

Energy bills are often criticised for being too complicated, but rather than simply filing them away because you don't understand them, you should always read them carefully to ensure that you aren't paying over the odds.

There are several bits of information every energy bill will show.

Every customer has a reference or account number, and this is vital if you have a query with your bill and want to speak to your energy supplier about it.

There will be a bill period on the statement, which shows the dates your bill relates to. The bill will also include information showing the last payment you made, as well as how much you are expected to pay for the latest billing period. This figure is usually shown with VAT excluded, with the amount of VAT you owe given below. There will then be a total figure that you will need to pay, which includes VAT.

Your bill will also include detailed breakdown of your energy usage. This will include the kilowatt hours (kWh) used, the cost per kilowatt hour and your latest meter readings. If there is an 'e' shown next to the meter reading, this will indicate that the reading is estimated rather than actual. Additional charges (such as standing orders) and discounts are then outlined before the total amount due is shown.

You should pay this amount as soon as possible. If you don't pay by direct debit, then a payment slip will be included at the bottom of the bill.

Why not check out our video that explains more about the infomation you can find on an energy bill, how you can take your meter reading and how you can save money on your energy bill.

What to do if your bill is higher than expected

Receiving an energy bill which is much higher than you anticipated can be a nasty shock. However, there may be several reasons why your bill is higher than you expected - we explain what they are:

Your meter readings have been estimated

If your gas or electricity supplier has based its bill on an estimated meter reading, rather than an actual reading then the chances are they may have over or under-estimated how much energy you've used.

You can tell is if the reading is estimated because it will usually have an 'e' next to it. To make sure you pay the correct amount, take a meter reading yourself and notify your gas or electricity supplier so they can send you a revised bill.

You have used more energy than usual

Think carefully about your energy usage and whether this has changed recently, prompting a higher bill. Perhaps there might have been a bout of freezing weather which has meant the heating has been on more than usual, or you've had people to stay and have used more hot water than you might have normally.

New appliances can also have an impact on your bills, so if you've bought new electrical items recently and used them a lot, this could have contributed towards steeper bills.

Your tariff has expired

One reason gas and electricity bills can suddenly increase is because your current energy tariff has expired. You may, for example, have locked into a fixed rate tariff some time ago, and have been protected from energy price increases.

But when this comes to an end, bills can shoot up, so it's always worth making a note of when your current deal is due to end.

Whatever the reason your energy bills have increased, if you are struggling to pay, you should contact your supplier as soon as possible to arrange a manageable repayment plan.

You should also take steps to reduce your bills as soon as possible. You can compare tariffs online through MoneySupermarket's energy channel to find the best deals, so if you find a cheaper quote you should switch as soon as possible.
