A fixed rate energy tariff could save you money and give you the peace of mind that the cost of your energy will stay the same for a set period of time.

Use our comparison to find the best fixed rate tariff for you, by thinking about:

How long are tariffs fixed for?

Usually between 12 months and two years, but this varies based on which deal you choose so check terms with the individual supplier.

The longer a tariff is fixed for, the higher the initial cost may be. Fixing the rate of your energy also means that, if energy prices drop, your rate will stay the same.

Can you switch before your fixed tariff ends?

Yes, but you may have to pay an exit fee of around 30 per fuel if you leave your contract more than 42 days before it ends.

This means if you have both gas and electricity with the same supplier, you will pay 60 to leave your contract early.

You do not always have to pay a cancellation fee to leave a fixed contract early, so use this comparison to look for deals where no exit fee applies.

What happens when your fixed rate ends?

Your energy company will automatically put you on a variable rate tariff, which means you may have to pay a higher rate for your gas and electricity.

You can speak to your supplier about moving to another tariff, and you can also switch supplier without charge if you have less than 42 days left on your fixed contract.
