Check when you can switch your business energy

You can usually switch your business energy if:

  • you’re on a contract you’ve not chosen – such as a deemed energy contract contract. These normally apply if you have new premises or a fixed-term contract ends and you haven’t yet signed up to a new energy deal
  • your business energy contract has expired and you aren’t bound by any terms. You may need to give notice in some business energy contracts. Check your terms and speak to your supplier if you aren’t sure about the notice period.

If a supplier says you can’t switch, they must explain why as soon as possible. They must also explain your options if you think you should be able to switch.

Information you need to switch business energy

It's useful to have the following information:

  • your postcode
  • the name of your current supplier and contract
  • the terms on your current business energy contract, including the contract end-date and any notice periods
  • your energy costs per unit (shown in kilowatt hours – kWh on your bill) and standing charges
  • your annual energy usage.

You can find important information on a recent energy bill. Log in to 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.

Find business energy contracts

Before agreeing a contract, contact the supplier you already have to see what they can offer compared to other providers. You can use a comparison website or phone different energy suppliers to do see what other providers are offering. 

You can also use energy brokers who can negotiate a contract for a fee. If you use a broker:

  • ask which suppliers they represent so you know if they can offer a full-market comparison.
  • make sure you are clear on the terms of their service. For example, they may charge a one-off finder’s fee or integrate their fee as part of a commission agreement in a contract you choose to sign up to. See GOV.UK’s advice on Avoiding unfair terms in business contracts.

It’s always worth asking your current supplier if they can beat an offer if you find one that’s better elsewhere too.

It’s also best to ask providers to send you a written offer with all terms before you say you agree to a business energy contract, including when checking offers by phone. Phone agreements are binding.

Weigh up your options

Think about things like:

  • a supplier’s customer service
  • if the offer is the cheapest price, environmentally-friendly or flexible to end without a fee
  • the notice period terms if you choose to end a contract
  • if you can get cashback or other free incentives as part of your switch offer
  • if you will have to pay any additional costs, like maintenance charges
  • whether the business contract offers a ‘cooling-off’ period if you change your mind after signing up
  • if you are using an energy broker, how their fee works with a contract. For example, is it a one-off charge, or added to the usage costs in your contract?

Choosing a contract

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.

Before you sign, make sure you understand:

  • the contract length
  • required notice periods if you want to switch or end a contract
  • the costs for each unit of gas or electricity used per kWh and standing charges.

If you change your mind

Many business energy contracts don’t offer a cooling-off period. This is the option of cancelling a contract within a certain number of days after it is agreed. So be sure that you are happy with all terms and conditions before you agree to a contract.
