| A UK business energy comparison in 2026 means benchmarking your contract against market averages of roughly 22p to 30p per kWh for electricity and 6.5p to 9p per kWh for gas, plus daily standing charges of around 45p to 65p and 25p to 45p respectively. Competitive fixed deals sit nearer 18p to 22p for electricity and 6p to 7p for gas. If your rates sit above those ranges, comparing will almost certainly save you money. |
That benchmark carries more weight this year than most. Network charges rose sharply from April 2026, the bulk of the increase landed on standing charges rather than unit rates, and businesses have had no price cap protection since the Energy Bill Relief Scheme ended in March 2023. Put plainly: nobody is watching your rate on your behalf.
This guide sets out what UK businesses should be paying in 2026, what actually determines the number you are quoted, what is about to change, and how to lock in a better deal before your renewal window closes.

What are the average business energy rates in the UK in 2026?
The average UK business pays 22p to 30p per kWh for electricity and 6.5p to 9p per kWh for gas on fixed contracts in September 2026. Smaller businesses sit at the top of each range because larger users negotiate on volume, while half-hourly metered sites can secure as little as 18p to 22p per kWh for electricity.
The table below shows indicative 2026 market rates by consumption band, including the standing charge — the figure most comparisons leave out and the one rising fastest this year. Treat every number as a benchmark rather than a quote. Your own rate depends on region, meter type, consumption profile and credit position.
Business electricity rates 2026 (indicative)
| Consumption band | Market average | Competitive fix | Standing charge |
|---|---|---|---|
| Micro: under 5,000 kWh | ~28 to 30p/kWh | ~24p/kWh | ~65p/day |
| Small: 5,000 to 15,000 kWh | ~27p/kWh | ~22.5p/kWh | ~60p/day |
| Medium: 15,000 to 50,000 kWh | ~25p/kWh | ~21p/kWh | ~55p/day |
| Large: 50,000 to 150,000 kWh | ~23.5p/kWh | ~19.5p/kWh | ~50p/day |
| Half-hourly: 150,000 kWh+ | ~22p/kWh | ~18p/kWh | ~45p/day |
Business gas rates 2026 (indicative)
| Consumption band | Market average | Competitive fix | Standing charge |
|---|---|---|---|
| Under 25,000 kWh | ~8.7p/kWh | ~7.5p/kWh | ~38p/day |
| 25,000 to 100,000 kWh | ~8p/kWh | ~7p/kWh | ~35p/day |
| 100,000 to 500,000 kWh | ~7.4p/kWh | ~6.5p/kWh | ~30p/day |
| 500,000 kWh+ / daily metered | ~6.8p/kWh | ~5.9p/kWh | ~25p/day |
Two numbers make up almost every bill. The unit rate is what you pay per kilowatt hour consumed. The standing charge is a fixed daily fee you pay whether you trade that day or not. Standing charges are the component rising fastest in 2026, which is precisely why a headline unit rate no longer tells you whether a quote is competitive.
SEFE Energy makes the same point from the supplier side: a tariff is a standing charge plus a unit rate, and “what could be a great deal for a high energy user might not be as good for a business that uses far less.” Always compare on an annualised total, not on p/kWh alone.
Prices have also not returned to where they were. Business electricity remains materially above pre-2021 levels, and one-year fixed rates for small businesses rose roughly 8% between 2025 and 2026 rather than falling, despite broadly flat wholesale forwards. The rises are coming from the non-commodity side of the bill, not the commodity side.
Not sure what you are currently paying? Your unit rate and standing charge are both printed on your latest bill. Our guide to what a utility bill includes shows you exactly where to look.
Why should businesses compare energy suppliers?
Because rolling over without checking almost always costs more. Out-of-contract and deemed rates are what you pay when a fixed term ends with nothing agreed to replace it. Your supplier sets them, they move with the market, and they typically sit well above a negotiated deal.
Inertia is the norm rather than the exception. Northern Gas and Power reports that close to 46% of businesses never review their options at contract end and simply accept the renewal offer that arrives. The same research points to Ofgem findings that weak competition costs consumers around GBP 2.9 billion a year, roughly GBP 1.6 billion of which is recoverable if buyers actually shop the market.
It is not that businesses do not care. NGP’s own client research found 62% of SMEs and microbusinesses describe energy as a significant cost, and ranked their priorities as price stability (75%), lowest overall cost (65%) and minimising the time and effort involved (47%). That last figure is the honest one: most firms roll over because comparing properly is a job nobody owns.
Unlike households, businesses get no price cap. That exposure cuts both ways — you carry the market risk, but a well-timed comparison captures savings a capped household never sees.
A proper comparison lets you:
- Cut your unit rate and standing charge against the whole market, not one renewal letter
- Avoid expensive default rates by acting before your renewal window closes
- Choose the right contract structure — fixed for certainty, flexible only if you can genuinely carry market risk
- Move to renewable or REGO-backed supply without automatically paying a premium
- Escape poor service by leaving a supplier with billing or support problems behind
See our guide on avoiding costly default rates when your contract ends for what happens if a term lapses unnoticed.
How does a business energy comparison work?
A business energy comparison matches your actual consumption data against live tariffs from multiple suppliers, then weighs price against contract terms and service quality. Done properly it takes three steps.
1. Review your current contract
Before requesting a single quote, gather:
- Your current supplier and contract end date
- Your unit rates and standing charges from a recent bill
- Your annual consumption in kWh for both fuels
- Your renewal notice period — miss it and you can be rolled onto default rates
- Your MPAN and MPRN, which suppliers need before they will price accurately
Consumption is the single most important number in the exercise. Accurate usage data produces accurate quotes; guesswork produces quotes padded for supplier risk, and that padding sits in your unit rate for the entire term. If your history is patchy, a broker can usually pull it for you; Northern Gas and Power, for instance, analyses fourteen months of historical usage through its own platform so the client never has to compile it.
2. Compare quotes from multiple suppliers
Two suppliers will quote the same business two different rates on the same morning. That is not a flaw in the market; it is the market. Each prices from wholesale costs plus its own hedging position, cost base and appetite for your sector.
Compare at minimum four things: the unit rate, the standing charge, the contract length, and whether the quote is fully fixed or leaves pass-through charges open to change mid-term. That fourth point matters more in 2026 than it has in years.
Breadth of panel is what makes the difference. Northern Gas and Power works across 40+ business energy suppliers and quotes 22 of them through its own comparison platform. Utility Market Watch compares across a panel representing more than 90% of the UK business energy market by customer numbers. One renewal letter is not a comparison; it is an opening bid.
3. Look beyond the headline price
The cheapest advertised rate is rarely the cheapest bill. A low unit rate paired with a high standing charge costs a low-usage business more overall, and after April 2026 that trap is wider than it has ever been. Weigh billing accuracy, service quality, renewable options and exit terms before you sign.
| Run this calculation before you sign anything Annual cost = (unit rate x annual kWh) + (standing charge x 365). Do it for every quote and rank on the total, not the p/kWh. On a 15,000 kWh site, a 10p/day difference in standing charge is GBP 36.50 a year; the equivalent of roughly 0.24p/kWh. On a 5,000 kWh site, the same 10p/day is worth 0.73p/kWh. The smaller you are, the more the standing charge decides the winner. |
What affects business energy prices in the UK?
Four factors set the rate you are quoted: usage, location, contract type and non-commodity costs. Our deeper guide on what affects your business electricity price covers the mechanics in full.
Business size and usage
Suppliers price on volume. A manufacturing site using 500,000 kWh a year gets a lower unit rate than an office using 15,000 kWh, because cost-to-serve per kWh falls as consumption rises. Usage pattern matters as much as volume: heavy daytime peaks price very differently from steady overnight loads, and that distinction is about to get sharper.
Location
Great Britain is split into 14 licensed distribution areas, each with its own network charges. Two identical businesses, one in London and one in Manchester, can pay noticeably different rates for the same usage purely because of where they sit on the network. The spread between the cheapest and most expensive distribution regions can reach around 4p/kWh.
Contract type
A fixed-rate contract locks your unit price and standing charge for one to three years — occasionally up to five — protecting you if the market climbs and making budgeting straightforward. A flexible contract buys energy in tranches across the term: cheaper when prices fall, painful when they spike, and it requires ongoing monitoring. SEFE Energy positions flexible purchasing as appropriate for very large consumers, generally those above 5,000,000 kWh a year. Most SMEs are better served by a competitive fix.
One detail that catches businesses out: unlike household contracts, business energy agreements carry no statutory cooling-off period. Once you sign, you are committed for the term. Check the standing charge, the term length and the pass-through treatment before the signature, not after it.
Non-commodity costs and the 2026 rises
Most of a business electricity bill is not electricity. Non-commodity costs now account for around 64% of the bill, covering network charges, policy levies and supplier margin. This is why falling wholesale prices do not reliably translate into falling bills, and why 2026 fixed rates rose even as wholesale forwards stayed broadly flat.
The headline 2026 story is transmission charges. TNUoS charges rose by a confirmed 64% from April 2026, with the residual element moving from roughly GBP 15.70/MWh to around GBP 25.70/MWh. Because that residual is recovered through standing charges rather than unit rates, the practical consequence is blunt: you can cut your consumption and still see your bill rise.
The Climate Change Levy adds 0.801p per kWh on both electricity and gas from April 2026, rising to 0.827p per kWh from April 2027, with VAT at 20% (or 5% for qualifying low-usage sites). Businesses holding a Climate Change Agreement receive a 92% discount on electricity and 89% on gas for 2026-27, which is worth checking if you sit in an eligible sector.
| Bill component | Roughly what it covers | 2026 direction |
|---|---|---|
| Wholesale commodity | The energy itself, around 36% of an electricity bill | Broadly flat on forward curves |
| Network charges (TNUoS / DUoS) | Transporting power across transmission and distribution networks | Up sharply — TNUoS +64% from April 2026 |
| Policy levies | Renewables support, capacity market, social schemes | Under active political pressure to move off bills |
| Climate Change Levy | Tax on business energy consumption | 0.801p/kWh, rising to 0.827p/kWh in April 2027 |
| Supplier margin and costs | Cost to serve, credit risk, hedging | Varies widely by supplier — this is what you compete away |
What is changing in business energy pricing after 2026?
Two developments will shape what you are quoted at your next renewal, and neither is widely understood yet.
Half-hourly settlement will reprice your consumption shape
Market-wide Half-Hourly Settlement (MHHS) replaces estimated and profiled consumption data with actual half-hourly measurement across the entire electricity market. Industry migration runs from October 2025 to May 2027, staggered in waves; SmartestEnergy sits in Wave 4, migrating customers between October 2026 and May 2027, with full industry cutover in July 2027 and settlement cycles shortening from fourteen months to four. Ofgem estimates the reform could deliver GBP 1.5 billion to GBP 4.5 billion of consumer benefit by 2045.
Nothing changes mid-term. Your contracted rates, terms and tariff structure hold for the full term you signed. The effect lands at renewal, when suppliers price against your genuine half-hourly consumption shape rather than an industry average profile.
| What this means for your next comparison If your consumption sits largely outside expensive peak periods — overnight manufacturing, early-morning bakeries, out-of-hours processing — MHHS should work in your favour at renewal, because you will finally be priced on when you actually use electricity rather than when an average business does. If you are peak-heavy, expect the opposite, and look at load shifting before the renewal rather than after it. |
Policy levies are under serious political pressure
On 11 September 2026, more than 120 organisations co-ordinated by Energy UK and E3G wrote to government calling for electricity levies to be moved off business and household bills and onto general taxation. The letter estimates the change could reduce business electricity prices by up to 20%, and argues that bringing UK electricity prices down to the G7 median could add GBP 250 billion of economic output over a decade.
Nothing is decided, and no business should price a contract on the assumption it happens. But it does affect term strategy: if you are weighing a one-year fix against a three-year fix in a flat wholesale market, the possibility of levy reform is a modest argument for not locking away every site for the longest available term. Stagger your renewals rather than betting the whole portfolio on one view.
Which are the best business energy suppliers in the UK for 2026?
The best supplier depends on your size, sector and priorities. These are the UK business energy suppliers most commonly compared in 2026:
| Supplier | Best suited for |
|---|---|
| British Gas Business | Established firms wanting a large, recognised supplier with broad SME coverage |
| EDF Business | Companies wanting big-supplier scale, fixed-term stability and large-user account management |
| E.ON Next Business | Businesses with sustainability targets and reporting obligations |
| ScottishPower Business | Small and medium-sized companies wanting straightforward fixed products |
| SEFE Energy / Crown Gas & Power | Larger commercial and industrial gas users; strong published guidance on contract structures |
| SmartestEnergy | Sites above 300,000 kWh a year prioritising renewable-backed supply, traceable REGO products or corporate PPAs |
| Northern Gas and Power | Businesses wanting a managed procurement service rather than a direct supply relationship |
For context on scale: SmartestEnergy holds roughly 3.1% of the UK commercial and industrial supply market and around 48.8% of the independent renewable market, and has operated since 2000 across the UK, US and Australia. Northern Gas and Power manages over 30 TWh of energy for more than 20,000 clients across three continents. Both are credible names — but neither, nor any other, is cheapest for every business.
The supplier that undercuts the market for a restaurant in Birmingham may be uncompetitive for a warehouse in Glasgow, because regional network charges and sector risk appetite both feed the price. That is the whole argument for comparing quotes rather than picking a name.
How much can businesses save by comparing energy suppliers?
Businesses coming off out-of-contract or deemed rates stand to save the most, because default rates run well above negotiated fixed deals. Even businesses already on a fixed contract usually find savings at renewal, since the old rate was priced against a different wholesale market and a different set of network charges.
Your savings depend on four things:
- How far your rate sits above the 2026 benchmarks — 22 to 30p/kWh electricity, 6.5 to 9p/kWh gas
- Your annual consumption. A 3p/kWh saving on 40,000 kWh is GBP 1,200 a year on electricity alone
- Contract timing. Comparing early in your renewal window means more suppliers quoting and more negotiating room
- Standing charge exposure, which is the critical variable after the April 2026 network increases
To date, Utility Market Watch has helped 2,500+ UK businesses save a combined GBP 1,455,000+ on their energy spend. Savings compound: a modest rate improvement across a three-year fixed term adds up to thousands you would otherwise hand your supplier for nothing.
Comparing is only half the equation. Cutting what you use protects you regardless of market direction, and some of it costs nothing — Northern Gas and Power notes that every 1 degree Celsius of overheating adds around 8% to heating costs. Our guide on how to reduce business energy consumption covers the changes that pay back fastest.
When is the best time to compare business energy prices?
The best time to compare is as soon as your renewal window opens, typically up to 12 months before your contract ends. Most suppliers will agree a new deal well in advance, with the rate starting the day your current contract expires.
Comparing early gives you three advantages: more suppliers willing to quote, time to negotiate rather than accept, and no risk of drifting onto out-of-contract rates. The worst time to compare is after your contract has already ended, because you are then paying default rates for every day you spend shopping.
If you want to time the market rather than simply beat your renewal letter, both Northern Gas and Power and SEFE Energy publish free market intelligence you can subscribe to — NGP issues a daily energy market report from its trading desk. Watching the forward curve for a few weeks before you commit costs nothing and occasionally saves a great deal.

Frequently asked questions
What is a business energy comparison?
A business energy comparison benchmarks your current electricity and gas rates against live quotes from multiple suppliers to find a cheaper or better-suited contract. It weighs unit rates, standing charges, contract terms and service quality, not just the headline price.
What is a good business electricity rate in the UK in 2026?
A competitive fixed rate sits around 18p to 22p per kWh, with the market average at 22p to 30p per kWh depending on business size. If you are paying above 30p per kWh on a fixed deal, you are very likely overpaying.
What is a good business gas rate in the UK in 2026?
A competitive fixed business gas rate sits around 6p to 7p per kWh, with most SMEs paying 6.5p to 9p per kWh. Larger, daily-metered users sit at the cheaper end of that range.
What is a typical business energy standing charge in 2026?
Business electricity standing charges typically run from around 45p a day for large half-hourly sites to around 65p a day for micro businesses. Gas standing charges run from roughly 25p to 38p a day. Both rose in April 2026 as the TNUoS increase fed through.
How often should businesses compare energy suppliers?
At every renewal, typically every one to three years, starting as soon as the renewal window opens and up to 12 months before the contract ends.
Can small businesses compare energy prices?
Yes. Small and micro businesses compare exactly as larger firms do, and often have the most to gain because they pay the highest unit rates. Microbusinesses also receive extra Ofgem protections around contract terms, notice requirements and renewals.
Is switching business energy suppliers difficult?
No. Once you agree a new contract, the incoming supplier manages the switch, there is no interruption to supply and no engineer visit is needed. You submit a meter reading and settle your final bill. Allow four to eight weeks for the transfer to complete.
Why did my business energy bill go up in 2026 even though I used less?
Because TNUoS network charges rose by a confirmed 64% from April 2026, and most of that landed on daily standing charges rather than unit rates. Standing charges apply every day regardless of consumption, so cutting usage alone cannot offset them.
Is there a cooling-off period on a business energy contract?
No. Business energy contracts carry no statutory cooling-off period, unlike household contracts. Once you sign, you are committed for the term, so check every figure before signing.
Will MHHS change what I pay for business electricity?
Not during your current contract. Market-wide Half-Hourly Settlement changes how consumption is measured and settled, migrating between October 2025 and May 2027. The effect shows up at your next renewal, when suppliers price against your actual half-hourly consumption shape rather than an industry average profile.
