Electricity

What is the average business electricity price per kWh in the UK?

12 August 2026 · 7 min read

Indicative unit rate ranges for business electricity by business size, what moves them, and how to work out if your quote is competitive.

Average business electricity unit rates in the UK generally fall between 22p and 32p per kWh, though the figure a specific business is quoted depends heavily on consumption volume, region, contract length and current wholesale conditions. There is no single national average that applies to every meter.

Smaller businesses on non half-hourly meters, such as shops, salons and small offices, typically pay towards the higher end of that range because fixed costs are spread across fewer units. A café using 12,000 kWh a year might be quoted 28p to 32p per kWh, while a warehouse using 500,000 kWh a year on a half-hourly meter might see 21p to 25p per kWh for the commodity element.

The unit rate you are quoted is not pure profit for the supplier. Roughly a third to a half of it, sometimes more, covers non-commodity costs: transmission and distribution network charges, the Renewables Obligation, the Feed-in Tariff levy, capacity market charges and balancing costs. These pass-through costs move independently of wholesale prices and are set by regulators and network operators rather than negotiated with your supplier.

Region affects the rate because the fourteen electricity distribution networks in Great Britain each charge differently for using their infrastructure. A business in the South West may see a different network charge component to one in the North East, even at identical consumption.

Contract length changes the rate too. A supplier pricing a one-year fix is exposed to less forward uncertainty than one pricing a three-year fix, so the relationship between term length and rate is not always straightforward, and it is common for a two-year deal to sit below both a one-year and a three-year quote depending on the shape of the forward curve at the time.

Worked example: if your current bill shows 30p per kWh and a new quote comes in at 26p per kWh on 40,000 kWh of annual consumption, the saving is 4p multiplied by 40,000, which is £1,600 a year before VAT. That is a meaningful enough gap to justify switching, once you have checked contract exit terms on your existing agreement.

To judge whether a quoted rate is competitive, look at your last twelve months of bills and calculate your own blended rate: total commodity spend divided by total kWh used. Compare that figure, not the headline rate on a single invoice, against new quotes, because seasonal consumption swings can distort a single month's figure.

Time of use also matters for half-hourly metered sites. Businesses that run heavy machinery, cold storage or catering equipment mostly during the day will be exposed to different average rates than a 24-hour operation, because wholesale and network costs vary by time of day.

It is worth being cautious of any supplier or comparison site that promises a fixed average rate for all businesses. Given how much unit prices vary by size, region, meter type and timing, a genuine quote can only come from submitting your actual consumption data and letting suppliers price against it.

Fixed contracts lock in a unit rate for the length of the agreement, which protects against rises but also means you will not benefit if wholesale prices fall during the term. Variable or flexible contracts track the market more closely and can work well for businesses with the appetite to monitor prices actively.

Prices also differ by fuel mix option. Standard grid electricity and REGO-backed renewable electricity are often priced similarly, though some suppliers charge a small premium for guaranteed renewable sourcing, so it is worth asking specifically if sustainability reporting is a priority for your business.

The most useful benchmark for any individual business is not a national average at all, but a like-for-like comparison across several suppliers using the same consumption data, submitted at the same time. Services such as Compare Market run this process across the market so you can see where your existing rate sits relative to what is actually available today.

It is also worth separating the unit rate you see quoted from the effective rate you actually pay once VAT, the Climate Change Levy and any capacity charge are included, since marketing materials and comparison tables do not always specify which figure they are showing. Two suppliers advertising the same headline pence-per-kWh figure can still produce different final bills once these additions are applied, which is another reason a full annual cost calculation beats comparing rate cards in isolation.

Businesses that have not reviewed their electricity contract in three or more years are statistically the most likely to be paying well above the current average, simply because they have been rolled through one or more automatic renewals at a supplier's default uplift rather than having been re-tendered. A quick check of your last renewal date is often the fastest way to spot whether your business electricity prices are worth revisiting now.

The way you are billed depends on your meter category. Smaller premises tend to sit on non half-hourly meters, read periodically and billed against actual or estimated monthly figures, while sites above a 100kW demand threshold move onto half-hourly settlement, where usage is logged in 48 slots a day and the resulting granularity often opens the door to sharper, more tailored pricing.

Standard VAT on electricity sits at 20%, though a 5% rate is available to businesses whose daily usage falls under roughly 33 kWh, or where most of the premises is used for domestic or charitable purposes rather than trade. The Climate Change Levy is charged on top of the unit rate for the majority of commercial accounts, with a small number of energy-intensive sectors qualifying for relief.

For context on scale, a corner shop or single-desk office might draw somewhere in the 5,000 to 20,000 kWh a year bracket, a busy restaurant or small trade unit tends to sit higher, often 20,000 to 75,000 kWh, and a factory floor or chain of stores can run into the hundreds of thousands or millions of kWh, at which point half-hourly settlement becomes standard practice rather than the exception.
