"How much does business energy cost?" is one of the most common questions we get — and the honest answer is that there is no single figure, because unlike your home, business energy has no price cap. This guide explains what actually makes up your bill, gives a rough sense of the numbers, and shows why the only meaningful "average" is the one on your own quote.
The two parts of every business energy price
Whatever you are quoted, a business gas or electricity price is built from two components:
- The unit rate (pence per kWh) — what you pay for each unit of energy you actually use. This is the number most people focus on.
- The standing charge (pence per day) — a fixed daily charge to keep your supply connected, whether you use much energy or none at all.
On a fixed-term contract, both are locked in for the length of the deal. A low unit rate paired with a high standing charge is not always the cheaper option, so it is worth comparing the two together rather than chasing the headline rate alone.
Why there is no simple "average"
Business energy is not covered by the Ofgem price cap — that only protects households. Your rate is set entirely by the contract you agree, which is why two businesses on the same street can pay very different prices. What sets yours comes down to a handful of things:
- When you signed. Wholesale energy prices move daily, so the rate you lock in depends heavily on the market on the day you agree your contract.
- How much you use. Larger users can often secure lower unit rates than very small sites.
- Your meter and contract. Meter type, contract length, payment method and credit position all feed into the price.
- Your location. Distribution costs vary by region.
We explain the no-price-cap point in full in our guide on whether the price cap applies to businesses.
A rough sense of the numbers
Purely for orientation — and stressing that these move constantly — small-business electricity unit rates in recent times have often sat somewhere in the region of the mid-twenties of pence per kWh, with gas typically in the high single figures per kWh, plus daily standing charges on top. Treat any figure like this as a snapshot only: it changes with the wholesale market and your own usage, and larger sites on half-hourly meters are priced differently again. The only accurate number is a live quote for your business.
The single most expensive rate is the one you never chose: if a contract lapses, you roll onto out-of-contract or deemed rates, which are usually far higher than a negotiated deal. Our renewal timing guide explains how to avoid that.
How to work out your real cost
You do not need a quote to get started — a recent bill tells you most of it:
- Find your unit rate (p/kWh) and standing charge (p/day) — both are on the bill.
- Note your annual usage in kWh (often shown, or add up 12 months).
- Multiply usage by the unit rate, add the standing charge across the year, and you have your annual energy cost.
- Compare that against what the wider market is offering for a business like yours.
How Win Energy helps
Because there is no cap and no fixed "average", the value is in comparison. We compare business electricity and business gas across a panel of UK suppliers, sized to your actual usage — and because we are independent, we will tell you honestly if your current deal is already competitive and worth keeping.

There is no magic number for what business energy "should" cost — only what the market will offer you today, for your usage, on the day you sign. Understand the two parts of the price, know your own numbers, and compare before you commit, and you will always be paying a fair rate rather than a lazy one.
