“What is the price of electricity per kWh in the UK?” looks like a one-line question and gets a thirty-line answer. The truth is that UK electricity prices per kWh depend on whether you are a household or a business, what tariff you are on, your supplier, your region, your meter type and the day you are quoted. This guide breaks down exactly what UK businesses are paying per kWh in 2026, where wholesale is heading, and how to lock in the right number for your meter.

What is the average price of electricity per kWh in the UK 2026?
As of Q1 2026, the average kilowatt cost UK figures look like this:
Business prices exclude VAT (20% standard, 5% reduced) and Climate Change Levy (0.775p/kWh). Source: average of new fixed contracts, Q1 2026.
How UK electricity price per kWh has moved 2019-2026
Three eras define the recent history of price electricity per kWh UK:
- Pre-2022 (stable era): 12-18p/kWh business average, 14-17p/kWh domestic. Wholesale 4-7p/kWh.
- 2022-2023 (energy crisis): business rates spiked to 35-50p/kWh in late 2022. Wholesale peaked at over 50p/kWh in August 2022. The government Energy Bill Relief Scheme (EBRS) capped wholesale exposure for 6 months.
- 2024-2026 (gradual normalisation): wholesale settled to 8-12p/kWh range. Retail business rates have come down to a 24-31p/kWh band but remain elevated vs pre-crisis. Network charges and policy levies have risen, partially offsetting the wholesale fall.
What makes up the price you pay per kWh?
For every 100p you pay on a typical UK business electricity bill in 2026:
- ~38p wholesale electricity — the actual electrons your supplier bought.
- ~22p network charges — transmission (TNUoS), distribution (DUoS), balancing (BSUoS).
- ~17p environmental and social levies — Renewables Obligation, Contracts for Difference, Capacity Market, CCL.
- ~10p supplier margin and operating cost.
- ~13p VAT (or ~3p if you qualify for 5% rate).
The implication: switching supplier can only cut roughly the wholesale + margin slice (~48% of the bill). The other half is set by Ofgem and applies whoever you buy from. To attack the rest, look at on-site generation, demand-side response and energy efficiency — covered in our energy audit guide.
Why UK businesses pay a higher kWh rate than households
Counter-intuitively, businesses often pay more per kWh than households despite using more energy. Three reasons:
- No price cap. Ofgem’s default tariff cap protects domestic customers; business customers have no equivalent protection.
- 20% VAT default. Domestic energy is 5% VAT; business energy is 20% by default.
- Climate Change Levy. Businesses pay an extra 0.775p/kWh CCL on electricity that domestic customers do not.
Larger businesses on half-hourly meters benefit from the opposite effect — their unit rate drops below domestic because they buy at scale and on more sophisticated tariffs. See our half-hourly meters guide.
How regional pricing affects your kWh rate
UK business electricity prices vary by region because the Distribution Use of System (DUoS) charge differs by Distribution Network Operator (DNO). The 14 DNO areas have different cost bases and asset profiles. Approximate variation:
- Cheapest regions: London, North West, Yorkshire (lower DUoS).
- Most expensive regions: Merseyside & North Wales, South West, North Scotland (higher DUoS).
The spread between cheapest and most expensive postcode in the UK is typically 2-4p/kWh on the same usage profile.
UK electricity price forecast 2026 and beyond
Forward curves on the wholesale market in early 2026 imply:
- Calendar 2026: wholesale around 9-11p/kWh; retail business around 24-29p/kWh.
- Calendar 2027: wholesale around 8-10p/kWh as new wind and interconnector capacity comes online; retail business 22-27p/kWh.
- Calendar 2028: wholesale around 7-9p/kWh; retail business 20-25p/kWh.
Net effect: most UK businesses fixing for 2-3 years now will pay slightly above market by year 3, but lock in protection from the next inevitable wholesale shock. Larger users with the appetite for it can use pass-through or flexible contracts to track wholesale down — see our tariffs guide.
How to find the lowest kWh price for your business
- Get on a fixed contract — out-of-contract and deemed rates are 50-80% above market.
- Lock in early in your 6-month renewal window when more suppliers will quote you.
- Compare every supplier — quote spreads of 30-50% are normal. Use a broker or comparison engine that quotes every UK supplier.
- Optimise for total annual cost not headline unit rate — standing charge can swing the answer.
- Apply for 5% VAT if you qualify (under 33 kWh/day or charity).

Frequently Asked Questions
The average UK domestic price under the Ofgem default tariff cap is around 26p/kWh. UK businesses pay more on average — 27-31p/kWh for SMEs and 19-24p/kWh for half-hourly metered users. Wholesale electricity sits at around 9.8p/kWh in Q1 2026.
Wholesale fell sharply from late-2022 peaks but network charges, environmental levies and supplier risk premiums have risen partially in response. Net retail prices have come down by 30-40% from peak but remain 50%+ above pre-2022 levels.
For micro and small businesses, business electricity is usually more expensive per kWh than the domestic Ofgem cap because of 20% VAT and the Climate Change Levy. Larger half-hourly metered businesses pay less per kWh than households because they buy at scale.
Look on any recent bill — the unit rate (p/kWh) and standing charge (p/day) are itemised on the front page or summary. Multiply your annual usage by the unit rate and add (365 × standing charge) to estimate your annual energy cost before VAT.
For 80% of businesses, a 24-month fixed contract signed within the 6-month renewal window will be the cheapest kWh tariff once you account for switching costs. Pass-through and flexible tariffs can beat fixed rates for very large users (over 1 GWh/year) actively managing their procurement.
Wholesale electricity in the UK is set on the day-ahead and intraday auctions run by EPEX SPOT and N2EX. The half-hourly system marginal price reflects the cost of the most expensive generator needed to meet demand. Gas-fired generation usually sets the marginal price, which is why UK electricity tracks gas wholesale closely.
