What Are the Current Business Electricity Rates in the UK? (2026)

How much does business electricity cost per kWh in 2026?

The average UK business pays 22p to 30p per kWh for electricity in 2026, plus a fixed daily standing charge. A small business specifically averages close to 29p to 30p per kWh as of August 2026. Larger users on half-hourly meters pay less per unit, closer to 17p to 22p, because they buy in volume.

Two numbers make up almost every bill. The unit rate is what you pay for each kilowatt hour you use. The standing charge is a fixed daily fee you pay regardless of usage, covering the cost of keeping your site connected to the grid. Standing charges are the part rising fastest in 2026, which we cover further down.

What are the average business electricity rates by business size?

Smaller businesses pay a higher unit rate than larger ones, because large users negotiate on volume. The table below shows illustrative 2026 averages based on typical annual consumption for each size band.

Annual costs above include an estimated standing charge and are illustrative, not quotes. The pattern to notice: a micro business pays a higher rate per unit than a large business, so the smallest firms carry the heaviest cost relative to what they use.

What makes up a business electricity bill?

Most of your bill is not the electricity itself. Non-commodity costs now account for around 64% of a UK business electricity bill, which means wholesale energy is the minority of what you pay. These non-commodity costs include network charges (TNUoS and DUoS), environmental and policy levies, and supplier margin.

Wholesale electricity, the raw energy, currently trades around £99 to £102 per MWh. That is far below the 2022 peaks above £400 per MWh, but the network and policy charges stacked on top keep final bills high. This is why a falling wholesale price does not always show up as a lower bill.

How does location affect your business electricity rate?

Where your business sits changes your rate because network costs vary by region. The UK is split into distribution regions, and each has its own charges for moving electricity across local infrastructure. Population density, distance from generation, and the efficiency of the local network all feed into the price. Two identical businesses in different regions can pay noticeably different rates for the same usage.

How do contract types affect your rate?

Your contract type sets whether your rate is locked or exposed to the market. There are two positions that matter most.

A fixed-rate contract locks your unit price and standing charge for a set term, usually one to three years. It gives you a stable, predictable rate you can budget around, and it protects you if the market climbs during your term.

A variable or out-of-contract rate applies when a fixed term ends and nothing new is agreed. These rates are set by the supplier, move with the market, and are typically far more expensive. They are designed as a temporary stopgap, not a deal to sit on. Securing a competitive fixed term before your renewal window closes is usually the most cost-effective move.

How do suppliers affect your rate?

Suppliers set their tariffs from wholesale costs plus their own operating costs and margin. Wholesale prices move with gas prices, supply and demand, and geopolitical events. On top of that, each supplier factors in market competition and how they run their business. The result is that two suppliers can quote the same business two different rates on the same day, which is exactly why comparing the market matters.

Will business electricity rates rise in 2026?

Yes. Business electricity rates are set to rise in 2026, driven mainly by Transmission Network Use of System (TNUoS) charges. NESO published the final 2026/27 TNUoS tariffs on 30 January 2026, and the charges are rising by roughly 60% from April 2026. Most of that increase lands on standing charges rather than unit rates, so even businesses that cut their usage can still see a higher bill.

These charges fund the investment Ofgem has approved to modernise the grid for the shift to net zero. The cost of that upgrade is passed to businesses and consumers. The practical takeaway: if your renewal falls in 2026, the standing charge portion of any new quote is likely higher than last year, so the unit rate alone will not tell you the full story.

Why is UK business electricity so expensive?

The main reason UK electricity is expensive is gas, not electricity itself. The UK uses gas-fired power plants to generate a large share of its electricity, so the price of gas sets the price of power. Disruption to gas supply, including the fallout from the war in Ukraine, and limited UK gas storage have kept that price elevated. Countries that rely less on gas for generation tend to pay less.

Businesses feel this more than households. Domestic customers are shielded by a price cap. Businesses have had no equivalent protection since the Energy Bill Relief Scheme ended in March 2023, which leaves them fully exposed to the market.

How can you reduce your business electricity costs in 2026?

You have three practical levers to pull, and most businesses use more than one.

First, time your renewal. Lock a competitive fixed rate before your current contract expires, so you never roll onto expensive out-of-contract rates. Never let a contract lapse into a variable rate by default.

Second, compare the whole market rather than one supplier. Rates vary between suppliers for the same business, so a single renewal quote is rarely the best available. This is where a broker earns its place, by benchmarking your usage against multiple suppliers at once.

Third, cut your reliance on the grid where it pays off. On-site generation such as solar, and switching to a renewable energy tariff, can lower both your exposure to wholesale swings and, in some cases, your standing charge burden. Whether it makes financial sense depends on your site and usage.
