Lock in a fixed rate and you might regret it if prices fall. Stay flexible and a market spike could blow a hole in your budget. And do nothing at all, and you can end up on the worst rates of the lot. With forecasters expecting bills to rise again this summer, now is not the time to leave your small business energy renewal to chance. Here’s how to think it through. ### **Why timing matters more than usual right now** Cornwall Insight’s latest forecasts point to the domestic price cap rising in July 2026, with a warning that October could be higher still — a signal that the wholesale costs feeding business contracts are under upward pressure too. Importantly, small businesses don’t benefit from the price cap at all; it protects households only. That means there’s no safety net under your business rate, and the contract you choose does all the work of managing risk. The takeaway isn’t “panic-buy” — it’s “don’t drift.” ### **The three positions a small business can be in** ### **Fixed-rate contracts** A fixed contract locks your unit rate and standing charge for a set term, usually one to five years. You get budget certainty and protection from spikes, which is why most small businesses prefer them. The trade-off is that you won’t benefit if prices fall mid-term, and fixing at the top of a market can mean overpaying for years. The skill is in the timing and the term length — not simply fixing for as long as possible. ### **Flexible contracts** Flexible (or “flex”) arrangements let you buy energy in tranches over time, smoothing out market peaks and troughs. They can work well for larger or multi-site operations with the volume and appetite to manage market risk actively. For most smaller businesses, though, the complexity and exposure usually outweigh the benefit — a well-timed fixed deal is simpler and safer. ### **Out-of-contract and deemed rates — the trap to avoid** If you let a contract lapse without agreeing a new one, you roll onto “out-of-contract” or “deemed” rates. These are set by the supplier and are typically the most expensive rates available — sometimes dramatically so. It’s the single most avoidable mistake in business energy, and it catches out thousands of small firms every year simply because a renewal date slipped past unnoticed. ### **When should a small business switch energy supplier?** The best time to act is during your renewal window — the period before your contract ends when you’re allowed to agree new terms, often several months ahead. Switching (or renegotiating) before that window closes is how you avoid being rolled onto expensive deemed rates. You generally can’t switch mid-contract without paying to exit, so the date to watch is your contract end date. Mark it, and start comparing two to four months out. ### **A simple renewal playbook** - Know your dates. Find your contract end date and your renewal window. Many suppliers let you lock a new deal months ahead. - Start early. Don’t wait until the final week. Beginning the conversation several months out gives you room to compare and time the market rather than accept a rushed offer. - Compare the whole bill, not just the unit rate. A low headline rate with a high standing charge can cost more overall. Look at both together for your actual usage. - Never let it lapse. If you can’t decide, securing any fair fixed deal beats sliding onto deemed rates by default. - Watch the auto-rollover. Check whether your contract renews automatically and on what terms — some rollovers tie you in at uncompetitive rates. ### **The takeaway** There’s no single “right” contract — the best choice depends on your size, your appetite for risk and, above all, your timing. What is universal is that doing nothing is the worst option, because it usually ends in deemed rates. In a market where prices are expected to climb again, the small businesses that come out ahead will be the ones that knew their renewal date and acted in good time. ### **Small business energy contracts: FAQs** **Can a small business switch energy supplier mid-contract?** Usually not without an early-exit fee. The practical window to switch or renegotiate is the renewal period before your contract ends — typically a few months out. Check your contract end date and act before it lapses. **Is a fixed or flexible energy contract better for a small business?** For most small businesses, a well-timed fixed contract is simpler and gives budget certainty. Flexible contracts suit larger or multi-site operations that can actively manage market risk. **What are out-of-contract energy rates?** They’re the default rates a supplier applies when your contract ends and you haven’t agreed a new one. They’re typically the most expensive rates available, so avoid them by renewing on time. **Not sure when your contract ends or what to do next?** Utilities Group can check your renewal window, compare the whole-of-bill cost across suppliers and help you time it right — with no pressure to switch.
