Business energy prices in the UK are rising again. The July 2026 price cap increased by 13.5%, driven by a spike in wholesale gas costs following supply disruptions in the Middle East. For business owners, the question is not just whether prices will rise further, but whether locking in a fixed rate now, through 2027 or beyond, is smarter than riding out market volatility on a variable contract.
Most guides answering this question focus on domestic households. Business energy works differently. There is no Ofgem price cap protecting businesses. Business electricity contracts are negotiated directly with suppliers, contracted separately from gas, and priced against wholesale forward curves. The rates businesses pay range from 22p/kWh on a well-timed fixed contract to 45p/kWh if you let a contract lapse and fall onto deemed rates.
This guide gives UK business owners the current market data, rate benchmarks, and a clear decision framework to answer: Should you fix your business energy prices until 2027?
Current Business Energy Prices in the UK (2026)
UK businesses pay an average of 27.4p per kWh for electricity in 2026, excluding VAT and the Climate Change Levy (CCL). Business gas rates average 7.5–9p/kWh on a fixed contract. These figures are down from the 2022–23 energy crisis peaks of 35–50p/kWh for electricity and 25p/kWh for gas, but remain roughly 50% above pre-2022 levels.
What you actually pay depends on your business size, annual consumption, Distribution Network Operator (DNO) region, meter type, and when you last renewed. The table below shows 2026 indicative fixed-rate electricity quotes by business size:
Business Size | Avg. Usage (kWh/yr) | Fixed Rate (p/kWh) | Out-of-Contract Rate |
Micro | Up to 10,000 | 22–26p | 32–45p |
Small | 10,001–25,000 | 24–28p | 35–48p |
Medium | 25,001–50,000 | 25–30p | 38–50p |
Large (HH metered) | 50,000+ | 19–24p | Contact supplier |
The most important number in that table is the out-of-contract rate. Businesses that let their contract expire and roll onto deemed rates pay 32–50p/kWh 50 to 80% above the market-best fixed contract. If your contract has already lapsed, switching to a fixed deal is the highest-priority action regardless of where the market is heading.
Why Business Energy Prices Are Particularly Important in 2026
Two trends are pushing business energy costs higher in 2026, independently of wholesale gas prices:
1. Rising Non-Commodity Costs
The unit rate you pay for energy has two components: the wholesale commodity cost and the non-commodity costs. Non-commodity costs include Transmission Network Use of System (TNUoS) charges, Distribution Use of System (DUoS) charges, the Renewables Obligation (RO), the Feed-in Tariff (FIT) levy, Contracts for Difference (CfD), Balancing Services Use of System (BSUoS), and metering charges.
In 2026, TNUoS charges increased significantly as National Grid passed on its investment in modernising UK energy infrastructure to meet net zero to businesses. These non-commodity costs now make up roughly 40–50% of the average business electricity bill. This means that even if wholesale gas prices fall further, total business electricity bills can stay high or rise because the network and policy cost floor is rising regardless.
2. Geopolitical Wholesale Volatility
As of late June 2026, wholesale gas prices have fallen by roughly 14–18% from their May peak, following a US-Iran ceasefire and the normalisation of LNG shipping. Forward curves now suggest a gentle downward trajectory for wholesale electricity from around 9.8p/kWh in Q1 2026 toward 8–9p/kWh by 2027–28, as new wind capacity and interconnectors displace gas generation.
However, this easing is driven by temporary factors, including geopolitical relief and summer heatwave conditions that suppress heating demand. The return of autumn demand and the winter heating season could reverse these falls within weeks. Businesses renewing before September 2026 are in a window where current market easing has likely already fed through into live supplier quotes.
Fixed vs Variable Business Energy: Which Is Better in 2026?
Fixed contracts are better for most UK businesses in 2026. Here is why the maths works out that way: wholesale forward curves are flat-to-falling toward 2027–28, but the decline is gradual and uncertain. Non-commodity costs are rising regardless of wholesale price direction. Out-of-contract deemed rates are 50–80% above market-best fixed deals. Taken together, fixing locks at a rate below what most businesses are currently paying on variable or out-of-contract arrangements, while the potential savings from waiting for wholesale to fall further are small and uncertain.
4 reasons to choose a fixed business energy contract:
Budget certainty: you know exactly what energy will cost for 12–36 months, regardless of wholesale price movements
Protection against spikes: if geopolitical tensions or a cold winter push wholesale prices up again, your rate is locked
Cheaper than variable in 2026: a properly negotiated fixed business electricity contract at 22–28p/kWh is well below out-of-contract and variable deemed rates
Non-commodity cost hedge: some fixed contracts lock in network and policy charges as well as wholesale rates, protecting you from the TNUoS and policy levy increases rising through 2026–27
2 reasons a variable or flexible contract might make sense:
Large users with in-house expertise: businesses using 1 GWh+ per year with dedicated energy managers can use pass-through or flex contracts to track wholesale markets and potentially save as prices fall through 2027
Very short-term needs: if you are closing a site, moving premises within 6 months, or operating on a short-term lease, a rolling monthly arrangement may be more practical than committing to a fixed contract
Should You Fix Business Energy Prices Until 2027?
Yes for most UK businesses, fixing until 2027 makes sense in June 2026. The specific conditions that make a 2027 fix rational right now:
Wholesale gas has fallen by 14–18% from its May 2026 peak, so live supplier quotes are reflecting the current market easing. This is a better entry point than April–May 2026
Cal-2027 wholesale electricity forward contracts sit around 9p/kWh, implying retail business electricity rates of 22–27p/kWh for contracts signed now with a 2027 delivery date
Winter 2026 demand recovery and heating season onset could push prices up again in Q4 2026, locking in now avoids that risk
Non-commodity charges (TNUoS, DUoS, levies) are structurally rising through 2026–27, so the floor under your total bill is higher regardless of wholesale direction
The case for waiting: if you believe wholesale gas prices will fall further through the summer before recovering in the winter, waiting 4–6 weeks could yield a slightly lower rate. Market data from late June 2026 suggests prices have already found a floor and the pace of decline is slowing. Chasing another 1–2% drop carries execution risk if prices reverse before you act, locking you in at a higher rate.
Practical rule: compare fixed-rate business energy quotes now. If the best available quote is at or below what you currently pay, fix. If the quote is higher than your current contracted rate, note when your contract ends and begin renewal 4–6 months before expiry.
How Long Should You Fix Business Energy For?
24-month fixed contracts are the best option for most SMEs in 2026. Forward curves show wholesale electricity for 2026–27 at around 9–10p/kWh and for 2027–28 at around 8–9p/kWh. The price difference between a 12-month and 24-month fix is small. Extending to 24 months gives an extra year of budget certainty at minimal extra cost. The table below summarises the options:
Contract Length | Best For | Watch Out For |
12 months | Businesses expecting wholesale to fall; very short-term leases | Rates may be marginally higher than 24m; the renewal window comes around fast |
24 months | Most SMEs best balance of price and flexibility in 2026 | Exit clauses if you move premises |
36 months | Stable, high-usage businesses wanting certainty through 2029 | Over-commits if your usage or premises changes significantly |
Pass-through / flex | Businesses using 1 GWh+ with in-house energy expertise | Requires active management; exposed to wholesale spikes |
One critical point most comparison guides miss: business electricity and gas are contracted separately. The cheapest gas supplier for your premises is rarely the cheapest electricity supplier. Quote them independently and compare total annual cost unit rate multiplied by annual kWh consumption, plus standing charge multiplied by 365 days rather than unit rate alone. A lower unit rate with a high standing charge can cost more in total than a slightly higher unit rate with a lower daily charge.
Business Energy vs Domestic Energy: Key Differences
Most 'should I fix' guides online are written for domestic households. Business energy works under different rules, and conflating the two is a common mistake.
No price cap: Ofgem's residential energy price cap does not apply to businesses. Business rates are set by direct commercial negotiation between your business and the supplier
Separate contracts: unlike households, businesses cannot get a true dual-fuel deal with matching rates. Electricity and gas are quoted and contracted separately
VAT and CCL: business electricity is subject to 20% VAT (not 5% as for domestic) and the Climate Change Levy at 0.775p/kWh, both excluded from headline comparison quotes
Exit fees: most business energy contracts in 2026 do not include exit fees, but some do, particularly for larger or longer-term deals. Check the termination clause before signing
Tariff types by usage: business electricity contracts include day-only, evening, weekend, and blended rates. Matching the tariff type to your peak usage pattern can reduce your total bill independently of unit rate
How to Compare Business Energy Prices and Get the Best Rate
Getting the best fixed business energy price in 2026 comes down to 5 actions:
Start your renewal 4–6 months before contract end: suppliers give their best rates during this window. Renewals initiated in the final 30 days before expiry attract a panic premium
Get quotes from at least 5 suppliers: quote spreads of 30–50% are normal for the same business meter. Checking just one or two suppliers leaves significant savings on the table
Compare total annual cost, not just unit rate: calculate (unit rate × annual kWh) + (standing charge × 365) for each quote. This is the only reliable comparison metric
Quote electricity and gas separately: the cheapest gas supplier at your postcode is rarely the cheapest electricity supplier. Quote both independently

The single biggest energy cost error UK businesses make in 2026 is letting a contract lapse. Falling onto deemed or out-of-contract rates at 32–50p/kWh for electricity costs significantly more than even a mediocre fixed deal. If your contract is expiring within 6 months, compare and fix now.
How Your Business Risk Profile Should Drive the Decision
Energy strategy is risk management. The right decision depends on 4 factors specific to your business:
Energy intensity: high-energy operations like manufacturing, cold storage, data centres, or commercial kitchens see larger absolute bill swings than low-use offices. A 5p/kWh rise on 200,000 kWh/year costs £10,000 extra annually at 10,000 kWh/year, it costs £500. The higher your consumption, the more important price certainty becomes
Cashflow tolerance: if a sudden energy bill spike could affect payroll, supplier payments, or borrowing capacity, certainty is worth more than the potential saving from a variable contract
Business stability: if you are planning to move premises, expand significantly, or downsize within 2 years, a 36-month fix could be problematic even without exit fees, the administrative complexity of re-contracting mid-term is worth avoiding
Contract terms: not all fixed contracts lock in network charges. Some include pass-through network cost clauses that allow the supplier to pass on TNUoS increases mid-contract. Read the non-commodity cost clause before signing
Frequently Asked Questions About Business Energy Prices
Should I fix my business energy prices now?
Yes, for most UK businesses in mid-2026. Wholesale gas has eased from May peaks, and live quotes reflect current market conditions. Non-commodity costs are rising regardless of wholesale direction, and out-of-contract deemed rates are 50–80% above market-best fixed deals. Waiting for further wholesale falls carries execution risk if winter demand recovers before you act, you pay more.
What are the current business electricity rates in the UK?
UK business electricity averages 22–30p/kWh on a fixed contract in 2026, depending on business size and region. Micro businesses (up to 10,000 kWh/year) pay the highest rates at 22–26p/kWh. Large half-hourly metered users pay 19–24p/kWh. Out-of-contract deemed rates run 32–50p/kWh across all sizes.
Is it worth fixing business energy for 2 or 3 years?
Yes 24-month fixed contracts offer the best value for most SMEs in 2026. Forward wholesale curves show electricity at 9–10p/kWh for 2026–27 and 8–9p/kWh for 2027–28 the price difference between a 12-month and 24-month fix is small, but the extra year of certainty is valuable. 36-month fixes work well for stable, high-usage operations.
Is business energy cheaper on a fixed or variable tariff?
Fixed tariffs are cheaper for most UK businesses right now. Variable business energy rates track wholesale markets, which is upside if prices fall but costly if they spike. In 2026, non-commodity costs (network charges, levies) are rising regardless of wholesale direction, making the floor under variable tariffs higher than it appears. Only businesses with 1 GWh+ annual consumption and in-house energy expertise should consider flexible or pass-through contracts.
How do business energy prices differ from domestic energy prices?
Business energy has no Ofgem price cap, is contracted directly with suppliers, and is subject to 20% VAT and the Climate Change Levy. Electricity and gas are quoted and contracted separately there are no true dual-fuel business deals. Business rates are generally higher per kWh than domestic for micro and small businesses, but can be lower for large half-hourly metered users with significant negotiating power.
When is the best time to compare business energy deals?
4–6 months before your current contract ends is the optimal renewal window. Suppliers offer their sharpest rates during this period. Comparing in the final 30 days before contract expiry often means paying a premium. Late spring (April–May) and late September are the cheapest seasonal windows to lock in energy demand is lower, suppressing wholesale prices. Compare business energy quotes on Switch to see current rates from 40+ UK suppliers.
What happens if I let my business energy contract expire?
You roll onto deemed or out-of-contract rates, typically 32–50p/kWh for electricity and 11–14p/kWh for gas. These are 50–80% above the rates available on a properly negotiated fixed contract. Some suppliers also require 28 days' notice to exit out-of-contract arrangements. Comparing and switching as soon as possible is the highest-priority action for any business currently paying out-of-contract rates.
