Managing business energy costs in an uncertain market
Summary
Ofgem blog post advising businesses on managing energy costs as contracts come up for renewal. Notes that network costs are increasing in April to fund infrastructure upgrades, and that wholesale costs remain volatile due to Middle East conditions. Estimates less than 10% of businesses recontracted in March-April, with 10-12% on deemed contracts.
Why it matters
Consumer guidance, not structural reform. The network cost increase reference is the only market-relevant signal, but the post provides no figures on the size of the increase or which charging methodology drives it.
Key facts
- •Wholesale costs approximately 40% of electricity bills, 60% of gas bills
- •Network costs increasing from April 2026 for infrastructure upgrades
- •Less than 10% of businesses recontracting in March-April 2026
- •10-12% of businesses currently on deemed contracts
- •Further 10% likely to recontract May-July 2026

Close alert: Managing business energy costs in an uncertain market Jemma Baker Deputy Director - Future Retail Markets - Consumer Protection and Competition Publication type: Blog Publication date: 31 March 2026 Topic: Non-domestic energy supply Subtopic: Third party intermediaries Print this page Share the page Share on Facebook Share on Twitter Share on LinkedIn 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 to upgrade energy infrastructure. 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.
