Your energy supplier has put its prices up

This advice applies to England

If your gas or electricity supplier increases its prices, they should tell you at least 30 days before the change takes place, unless:

  • your prices are changing because your supplier is changing the way you pay - such as if they're installing a prepayment meter (you'll get 7 days' notice)

  • you're on a 'staggered tariff', where your contract contains set price increases on set dates (you won't get a reminder)
  • you're on a 'tracker' tariff, where your prices will go up and down to follow something else, such as a stock market (you won't get any notice)

You should complain to your supplier if they don't give you the right amount of notice.

How to avoid the increase

To avoid the increase, you can compare tariffs from different suppliers to see if you could get a better deal. Make sure you act quickly - you'll need to ask to change tariffs before the price is increased.

If you change tariff with your current supplier, they must put you on the new tariff no later than 20 working days after the price increase was due to start.

If you switch to a tariff with a new supplier, they must tell your current supplier they're taking over your supply. They have to do this no later than 20 working days after the price increase was due to start.

If you owe money on your account, your current supplier can prevent the switch until you've paid. They must write to tell you they're doing this. If you pay the balance within 30 working days of them telling you, the switch can still go ahead and your current supplier mustn't increase the price.

If you’re on a 'fixed rate' tariff

Your supplier can’t increase the price you pay for energy unless:

  • the government has raised VAT
  • you have a tariff that has structured price changes set out in advance

If you’re unsure what tariff you’re on, check your bill. If it says your contract has an end date, you'll most likely have a fixed term tariff. Use our tool for understanding your bill if you're unsure where to find this information.

When your fixed rate tariff ends

The price you pay for energy will normally go up if your contract ends. This is because your supplier will normally move you on to a 'standard tariff', which will be one of the most expensive tariffs they offer. You’ll need to either change tariff or switch provider - look for a better deal.

You’ll be given 42 to 49 days’ notice before the contract ends to decide if you want to stay with your supplier or switch. You won't have to pay an exit fee to leave in this period. 

You should complain to your supplier if:

  • you don’t get notice about the end of your fixed term contract
  • you’re charged an exit fee to switch suppliers less than 42 days from the end of your contract
  • you get rolled over to another fixed term contract without your agreement
