What changed

Ofgem published a blog providing advisory guidance on business energy costs in an uncertain market. The document explains that energy bills comprise wholesale costs (approximately 40% for electricity, 60% for gas), network costs, and environmental costs. Network costs are increasing from April 2026, while wholesale costs remain volatile due to Middle East tensions. Ofgem estimates less than 10% of businesses will recontract in March-April 2026, with an additional 10-12% on deemed contracts and 10% recontracting in May-July. No new regulatory requirements are imposed.

Businesses with expiring fixed-price contracts should contact their supplier to discuss options, considering both short and long-term contracts. Ofgem advises businesses to submit regular meter readings, verify caller credentials to avoid fraud, and request contracts in writing. Suppliers may require security deposits due to increased default risk. The guidance includes a reminder that energy suppliers are not obligated to offer contracts and that no cooling-off period exists for business energy contracts.

What to do next

Review current energy contract end dates and contact suppliers in advance if renewal is approaching
Submit regular meter readings or arrange smart meter installation to ensure accurate billing
Verify credentials of any unexpected callers claiming to be energy suppliers or brokers to avoid fraud

The price you pay for energy for your business can vary across suppliers and the type and size of your business, but covers a range of costs including the wholesale energy cost (the cost to buy energy), network costs (the infrastructure to transport energy), and environmental costs (government decarbonisation schemes). Typically, wholesale costs can be about 40% of your electricity bill and about 60% of your gas bill, but exact percentages will vary.

In April, network costs are increasing. Wholesale energy costs are volatile and will continue to be affected by the situation in the Middle East.

Our understanding is that the majority of businesses are not currently exposed to immediate price increases as contract lengths are starting to return to 3 to 5 years in length. Based on current evidence, we expect less than 10% of businesses to recontract in March and April, with a further 10-12% currently on deemed contracts, and a further 10% likely to recontract in May to July.

However, if your fixed price contract is coming to an end, you will need to negotiate a new contract with your supplier.

Talk to your supplier about your contract options

If your current contract is coming to an end, talk to your supplier about what options are available.  If you have an energy broker, they can do this for you.

Consider your options

Ask suppliers what contracts are available and consider both short and long-term options. It may be better for you to temporarily stay on deemed or out of contract rates if the current longer-term contract offers are high.

Things to be aware of

When thinking about your contract options, you should be aware that:

suppliers may require security deposits because of greater risks of businesses defaulting on payment
energy suppliers are not obliged to offer businesses a contract and offers may be harder to find
you shouldn’t feel pressured into signing a contract and there is no cooling off period, so check the terms and fees beforehand
if you discuss a contract over the phone, you should ask for it in writing before agreeing it
you can avoid fraudsters by verifying unexpected calls. If in doubt about the caller, stop and check their details

Keep in contact with your supplier

Your supplier must treat you fairly and bill you accurately based on your meter readings. To ensure you are only paying for what you use, submit regular meter readings or get a smart meter. It is also important you keep your contact details up to date so that you receive your bills.

If you are having problems managing your bill, you should talk to your supplier or your energy broker. Your supplier can also offer you advice on reducing your bill.

Get help if your business cannot afford its energy bills.
