Business Energy Prices per kWh: What UK Businesses Pay in 2026

Every week someone asks me some version of “what should I be paying per kWh?” — and the honest answer is that the averages you’ll find online are almost useless for your meter. Here’s why, what actually drives your rate, and how to benchmark properly.

Prices referenced below are indicative for mid-2026 and move with the wholesale market. Treat them as orientation, not a quote.

Why there’s no single “business rate”

Domestic energy has a price cap; business energy doesn’t. Your rate is individually priced from:

• Consumption volume. Larger usage generally means lower unit rates — suppliers spread their fixed costs over more kWh.
• Region. Distribution charges differ by network area; the same supplier prices the South West differently from London.
• Meter type. Half-hourly supplies are priced bespoke; standard meters get tariff-book pricing.
• Contract length and timing. You’re buying the wholesale market as it stands on the day you fix — the same meter quoted a month apart can differ meaningfully for no reason other than the forward curve.
• Credit profile. Weaker credit means risk premium or security deposits.
• What’s in the rate. Some quotes include intermediary commission you can’t see — typically 1–2p/kWh through a conventional broker.

Two neighbouring businesses can both hold “competitive” contracts 20% apart, and both be right.

Orientation figures for 2026

Very rough mid-2026 orientation for standard SME supplies:

	Typical competitive range	Notes
Electricity unit rate	mid-20s to low-30s p/kWh	smaller users at the top of the range
Electricity standing charge	from ~60p/day	rises sharply on larger supplies
Gas unit rate	mid-single figures p/kWh	larger or well-timed contracts below it

If you’re significantly above these ranges, either your contract predates a market fall, someone’s margin is in your rate, or you’ve drifted onto out of contract rates — which routinely run at roughly double competitive levels.

For official averages, the government publishes quarterly business energy price statistics (DESNZ, “Prices of fuels purchased by non-domestic consumers”) — useful for trend, though it lags the live market by months.

The per-kWh trap

The unit rate is only part of the bill. A low unit rate with a 300p/day standing charge can cost a small meter more than a higher rate with a 60p/day charge. Benchmark on total annual cost for your consumption:

(unit rate × annual kWh) + (standing charge × 365) + CCL and VAT

That formula is also how we make quotes comparable in an energy audit — suppliers structure quotes differently precisely because it makes lazy comparison flattering.

How to benchmark your own contract

1. Take your latest bill: unit rate, standing charge, annual consumption.
2. Compute your total annual cost with the formula above.
3. Get live quotes for the same duration and consumption — the market is the only benchmark that matters, and it’s the one averages can’t give you.

Or have us do it: benchmarking is the first step of every procurement engagement, our fee is agreed upfront, and if your current contract stands up, we’ll tell you so.
