Every quarter, when Ofgem announces a new energy price cap, it makes the national news. In July 2026 the announcement was hard to miss: the domestic cap went up by roughly 13% for the period 1 July to 30 September 2026, driven by higher wholesale gas prices. Within that headline figure, electricity rose about 5% and gas jumped around 24%.
If you run a small business, that news matters, but almost certainly not in the way you think. The most common misconception we hear is that this price cap keeps a lid on what your business pays. It does not, and understanding why could save you thousands of pounds a year.
The price cap only protects households
The Ofgem energy price cap is a domestic measure. It sets a maximum on the unit rates and standing charges a supplier can charge a typical household on a standard variable tariff. It exists to protect ordinary consumers who may not shop around.
Business energy sits entirely outside that system. There is no regulatory cap on what a supplier can charge a UK business for its unit rates or its standing charges. A supplier is free to quote whatever the market, and your negotiating position, will bear.
When the news says "the price cap has gone up by 13%", read it as "household bills are changing". It tells you nothing about the deal available on your business meter, which is priced on a completely separate basis.
This catches people out because "price cap" sounds like a universal safety net. For your home it is. For your shop, cafe, office or workshop, it simply does not apply.
What actually drives your business energy bill
Without a cap, your business bill is shaped by two things: the wholesale market at the moment you agree your contract, and a growing stack of non-energy costs bundled into your rates. The second part is where a lot of the recent pain has come from.
Chief among these is the cost of the transmission network, the high-voltage grid that moves power around the country. From 1 April 2026 the demand-residual element of TNUoS, the charge that funds that national transmission grid, rose by around 94% year on year. That is not a typo. Costs like this land largely in your standing charge, the fixed daily amount you pay before you have used a single unit of energy.
A typical single-phase SME meter in 2026 carries a standing charge somewhere in the region of 60 to 110 pence per day on a competitive fixed contract. Over a year that is a meaningful sum before any usage, so it deserves as much attention as the unit rate.
The result is that many business owners focus entirely on the pence-per-kWh unit rate and never look at the standing charge, where a large and rising share of the cost now hides.
No cap means the spread between quotes is huge
Here is the flip side of having no price cap, and it is genuinely good news if you act on it. Because nothing forces suppliers toward a common maximum, the gap between a good quote and a bad quote on the exact same meter is wide. We commonly see a spread of 30 to 50% between the best and worst offers for an identical business.
For a household protected by the cap, shopping around might save a modest amount. For a business, comparing properly is one of the highest-value hours of admin you will do all year. The absence of a cap is precisely why comparison matters far more for businesses than for households.
This is where looking across the whole market pays off. You can start by understanding the two biggest lines on most bills, business electricity and business gas, and how each is quoted.
What to do about it
You cannot rely on a regulator to keep your business bill fair, so the responsibility sits with you. The good news is that a few disciplined habits put you back in control.
- Compare across the whole market, not one supplier. A single renewal quote tells you nothing about whether it is competitive. Only a like-for-like comparison of several suppliers does.
- Watch the standing charge, not just the unit rate. With network costs rising, a low unit rate can hide an expensive daily charge. Judge the total annual cost for your actual usage.
- Time your renewal. Review your contract 3 to 6 months before its end date. That window gives you time to compare calmly and lock in a rate rather than scrambling at the last minute.
- Never sit on deemed rates. If you let a contract lapse, you roll onto "deemed" or out-of-contract rates, which are among the most expensive in the market. This is the single most avoidable overpayment we see.
- Keep your renewal date on record. Set a reminder so a rollover never happens by accident.

An honest word on switching
Win Energy is an independent broker. We compare a panel of suppliers for you, free of charge, and we are paid a commission by whichever supplier you choose. But that does not mean we will always tell you to switch.
If we run the numbers and find you are already on a genuinely competitive contract, we will tell you to stay put. Sometimes the honest answer is "do nothing", and we would rather say that than push you into a deal that does not beat what you have. A comparison costs you nothing and, at worst, gives you the reassurance that your current rate stands up.
If your renewal is on the horizon, or you simply want to know whether you are overpaying, get in touch and we will check it for you. No cap is protecting your business, so the smartest thing you can do is make sure the market is working for you instead.
