Yes — but you may have to pay exit fees
You can switch electricity supplier at any time. If you’re still in a fixed-term contract, your supplier may charge exit fees (early termination fees). The key is to compare those fees against the savings you’d make by switching to a cheaper deal.
Decision framework: fee vs savings
- Work out the exit fee — Check your contract; it’s often a set amount per fuel or per remaining month.
- Estimate annual savings — Use a comparison to see how much you’d save over 12 months with a new rate.
- Compare — If savings (e.g. over the next 12 months) are greater than the exit fee, switching early can still pay.
Renewal window: switch without fees
Most business electricity contracts have a renewal window (e.g. 30, 60, 90 or 120 days before the contract end date). During this window you can switch without paying exit fees. That’s the best time to compare and move — see our guide to the business electricity renewal window.
Locking in future rates
You can also agree a switch that starts when your current contract ends. You lock in the new rate now and avoid exit fees because the change happens at the end of your term. Many suppliers offer future-dated contracts for this reason.
