What are business electricity rates in the UK?

Business electricity is priced on two parts: a unit rate (the price per kWh you use) and a standing charge (a fixed daily fee to keep your supply connected). In 2026, typical rates are:

Small business: around 27–30p per kWh

Medium business: around 26p per kWh

Large business: around 22–26p per kWh, often lower on negotiated contracts

Rates move with wholesale energy prices, so the figure you're quoted today may differ next month. For a full breakdown by business size and region, see our guide to current business electricity rates in the UK. To get a rate for your business, compare quotes here.

How much does business electricity cost per kWh?

Most UK businesses pay between 22p and 30p per kWh in 2026. A low unit rate isn't always the cheapest deal: a headline-low unit rate paired with a high standing charge can cost more overall than a slightly higher unit rate with a low standing charge. We compare both parts across suppliers so you see the true annual cost, not just the sticker price.

What is a standing charge on business electricity?

The standing charge is a fixed daily fee you pay regardless of how much electricity you use. In 2026 it typically runs 45–65p per day for small and medium businesses, and higher for large sites with greater capacity. If your usage is low, the standing charge makes up a bigger share of your bill, which is where our 0p standing charge tariffs can save you the most.

Business electricity contract types explained

Fixed-rate: your unit rate is locked for the contract term (typically 1–5 years). Protects you from price rises; you won't benefit if the market falls.

Variable-rate: your rate moves with the market. More flexibility, less certainty.

Deemed / out-of-contract: the default, most expensive rates you're placed on if a contract lapses. Worth switching off as soon as possible.

Green tariffs: electricity matched to renewable generation. We exclusively partner with renewable suppliers, so you can cut emissions while you switch.
