Switching energy tariff or supplier

How to compare and switch energy tariff or supplier when shopping around for a new energy deal.

How to switch

  1. Information you need

    It's useful to have the following information:

    • Your postcode.
    • The name of your current supplier.
    • The name of your current energy tariff.
    • Your annual energy usage or costs.

    You can find your tariff, supplier and annual information on a recent energy bill. Log into your online account if you don’t get paper bills.

    If you aren't sure about your current supply details, see Finding your energy supplier or network operator.

  2. Find tariffs and suppliers

    Use a comparison website or phone different energy suppliers to find out what you can save by switching. 

    You can ask your supplier if they will match an offer if you find one that’s better elsewhere.

  3. Weigh up your options

    Think about things like:

    • A supplier’s customer service.
    • If the offer is the cheapest, environmentally-friendly or flexible to leave without an exit fee.
    • If you can get cashback or other free incentives as part of your switch offer.
    • If there is a switching guarantee. Some suppliers offer this to help you switch with confidence.
  4. Confirm your switch

    The last step is to confirm your contract and payment method. Paying by Direct Debit usually saves money. 

    Your new supplier will contact you with a switching date. It can take up to 21 days to complete a switch. In most cases, it’s around 17 days.

    If you change your mind

    You have 14 days to cancel from when you agree to a contract.
