What business energy actually costs in 2026
If you run a small or medium-sized business in the UK, the numbers on your energy bill this year probably feel higher than they should. So let us start with plain figures rather than sales talk. In mid-2026 most small firms are paying somewhere around 27 to 30 pence per kilowatt hour for electricity, plus a daily standing charge that commonly lands between 45 and 70 pence. Business gas on a fixed contract sits at roughly 7 to 9 pence per kilowatt hour, with standing charges usually in the 25 to 45 pence a day range.
Those are averages, and averages hide a lot. The rate your neighbour pays for an identical shop unit could be very different from yours, purely because of when each of you last signed and which supplier you happened to use. That gap matters more than most owners realise, and we will come back to it.
The number to remember: on the same meter, the spread between the cheapest and most expensive quote is commonly 30 to 50 per cent. That is real money left on the table by not comparing properly.
Where your money actually goes: wholesale versus network
A business energy bill is not one price bolted together. Broadly, it splits into the wholesale cost of the energy itself and the cost of getting that energy to your door. Understanding the split explains why prices have not fallen back the way many people expected.
Wholesale is the part that grabbed headlines during the crisis. It has since calmed down, and forward prices are now roughly flat looking out into 2027 and 2028. If wholesale were the whole story, your bill would be noticeably cheaper than it was. It is not, and the reason is the other half.
Network and standing charges have climbed hard. These cover the poles, wires, pipes and substations, and the ongoing job of reinforcing the grid so it can carry more electricity. The industry calls the electricity network elements DUoS and TNUoS; you do not need the jargon, only the consequence, which is that a fixed daily cost is now baked into every bill regardless of how little you use.
The standing charge story nobody warned you about
This is the change that quietly hurts small users most. A typical SME paid in the region of 38 pence a day in standing charges back in 2021. Today many are paying 60 to 70 pence a day. That is a fixed cost you carry whether the lights are on or the unit sits empty over a bank holiday weekend.
For a low-usage business, a shop, a small office, a takeaway that trades set hours, the standing charge can be a surprisingly large slice of the total. It also means switching decisions cannot be made on unit rate alone. A deal with a tempting per-kilowatt price and a punishing standing charge can easily cost you more across the year than a plainer-looking quote. When we compare on your behalf we look at the blended cost for your actual pattern of use, not the headline rate.
How long should you fix for while wholesale is flat?
Because forward prices are broadly level through 2027 and 2028, the usual logic of "fix short and wait for prices to drop" does not hold as neatly this year. There is no clear downward slope to wait for. In that flat picture, longer fixed contracts of 24 or 36 months often work out as the cheapest blended option compared with a rolling series of 12-month deals, and they give you budget certainty that is worth having in its own right.
That said, longer is not automatically right for every business. A few honest things to weigh:
- If you expect to move premises or change how much energy you use, a shorter term keeps you flexible.
- Long fixes lock in today's higher standing charges too, so the unit saving has to justify the commitment.
- Some sectors prefer to keep options open; certainty has a value, but so does not being tied in.
There is no single correct answer, and any broker who gives you one without looking at your usage is guessing. Sometimes the honest advice is to stay where you are for now, and we are happy to say so.
The trap that costs the most: deemed rates
The single most expensive thing an SME can do is let a contract simply run out. When a fixed deal lapses and you have not signed a new one, the supplier moves you onto deemed, or out-of-contract, rates. These are the highest prices in the market, and you can sit on them for months without noticing until the bills arrive.
Avoiding this is mostly about timing. Best practice is to start reviewing three to six months before your contract end date. Suppliers will not let you sign a new fixed deal too far ahead, but you can line one up now to start on your renewal date, so there is never a gap where deemed rates catch you. If your site is half-hourly metered, meaning peak demand above 100 kilowatts, you will also need a specialist supplier, and that is a market worth having someone navigate for you.
Why a free whole-of-market comparison is worth it
Most SMEs are paying around 2 to 7 per cent more than they were in late 2024, so margins on energy are tight and every percentage point counts. Given a 30 to 50 per cent spread between the best and worst quote on the very same meter, the value of comparing widely is obvious.
Win Energy has been an independent broker since 2012. We compare a panel of suppliers across business electricity and business gas, the service costs you nothing, and we are paid a commission built into the unit rate by whichever supplier you choose. Because we are not tied to one supplier, we can tell you plainly when your current deal is already competitive and switching would not help. If it is time to look, get a quote and we will do the legwork on your actual figures rather than a headline rate.
