When Should Your Small Business Renew Its Energy Contract in a Volatile Market?

If your business energy contract ends in the next twelve months, you have a decision to make — and this year it is a harder one than usual. Wholesale gas and electricity prices have swung sharply through the spring, and nobody can tell you with confidence where they will sit by autumn. The good news is that you do not need to predict the market to make a sensible renewal decision. You need a plan.

Why prices are so unpredictable right now

Britain imports a large share of its gas, including liquefied natural gas shipped from around the world. That means events thousands of miles away — conflict, shipping disruption, outages at export terminals — feed through to the price your supplier pays, and eventually to the price you pay. This spring has produced plenty of all three, and wholesale prices have at times moved by double-digit percentages within a single month. Households have a price cap to smooth the ride; businesses do not. When your contract ends, you are exposed to whatever the market is doing that week. Ofgem publishes general guidance for business energy customers, which is a sensible starting point.

The real cost of doing nothing

If your fixed deal ends and you have not arranged a new one, you will not be cut off. Instead, your supplier moves you onto “out-of-contract” or “deemed” rates — and these are consistently among the most expensive ways to buy energy. Ofgem’s own guidance notes that deemed contracts tend to cost more than negotiated terms, because the supplier prices in the risk of serving a customer it knows little about. For a small firm, drifting onto these rates for even a few months can quietly wipe out a year of careful cost-cutting elsewhere in the business.

Five practical steps before you renew

  1. Find your end date and your notice window. Dig out your contract, or ask your supplier in writing for your contract end date and any notice requirements. Some contracts still auto-renew if you miss the window, so put both dates in your calendar today.
  2. Start earlier than feels necessary. Most suppliers will quote well before your current deal ends, and you can usually sign a new contract months in advance that starts the day your old one finishes. Starting early turns a forced decision into a choice.
  3. Decide what certainty is worth to you. A fixed contract gives you a known unit rate for the term — valuable when cash flow is tight and markets are jumpy. Flexible or tracker-style arrangements can win when prices fall, but you carry the risk when they rise. For most small businesses, budget certainty is worth more than the gamble; just avoid fixing in a panic on the day of a price spike if you have time to wait for calmer conditions.
  4. Compare the whole bill, not just the unit rate. Standing charges, the Climate Change Levy, VAT treatment and any fees all shape what you actually pay. Two quotes with identical unit rates can produce very different annual costs, so always compare the estimated total for your real consumption.
  5. Get more than one quote — on a like-for-like basis. Ask each supplier or adviser for the same contract length and start date, and for the figures in writing. If someone pressures you to sign the same day, treat that as information about them, not about the market.

Already on out-of-contract rates? You are not stuck

A surprising number of businesses sit on deemed rates for months because they assume they must wait for something — a renewal letter, an anniversary, an exit window. Usually, none of that applies. Deemed contracts exist precisely because no agreement was signed, and the rules that govern them are deliberately loose in your favour: in general you can leave a deemed contract whenever you like, without notice and without a termination fee, simply by agreeing a proper contract with your current supplier or a new one. The only real cost of being on deemed rates is time — every additional week is billed at some of the most expensive prices the supplier offers. If this is you, gathering quotes today is almost certainly worth more than any amount of waiting for the market to improve.

One caution: if you are in this position because you recently moved into new premises, make sure the supplier has your correct details and meter readings before you sign anything. Billing errors made at move-in have a way of following a business around for years, and they are far easier to fix before a new contract starts than after.

The takeaway

You cannot control the wholesale market, and neither can anyone who claims they can. What you can control is timing, information and options: know your dates, start early, compare full annual costs, and never let a contract lapse into deemed rates by accident. In a volatile year, the most expensive strategy is not choosing the wrong contract — it is not choosing at all.

Frequently asked questions

What happens if my business energy contract expires and I do nothing?
Your supply continues — you will not be disconnected — but you move onto out-of-contract or deemed rates, which are typically much higher than negotiated prices. The sooner you agree a proper contract, the sooner the overpaying stops.
How far in advance can I renew my business energy contract?
Many suppliers will quote and contract months ahead of your end date — in some cases up to a year. The new deal simply starts when the old one finishes, so renewing early does not mean paying twice.
Can I switch supplier while I am on deemed rates?
Yes. Deemed contracts can generally be left at any time without notice or exit fees, because you never signed fixed terms. Outstanding balances must still be settled, but you should not be held on deemed rates indefinitely.
Is a longer fixed contract always cheaper?
No. A longer term buys certainty, not necessarily a lower rate — suppliers price future market risk into multi-year deals. Compare the total annual cost of each option against how much budget stability is worth to your business.
