A business energy prices comparison shows fixed-rate contracts currently range between 22p–28p per kWh for electricity and 6p–9p per kWh for gas, depending on contract length and supplier. If your current contract ends within 3 months, fixing now locks in a predictable rate before non-commodity charges rise further. This guide explains exactly when fixing makes sense, when it does not, and how to compare commercial electricity rates to get the best deal for your business.
What Is a Fixed Business Energy Contract?
Yes, a fixed business energy contract locks your unit rate for the full contract term typically 1, 2, or 3 years. Your bill still changes monthly based on how much energy you use, but the rate per kWh stays constant. This differs from a variable or flexible tariff, where rates move with wholesale market prices.
Fixed contract energy gives you a known cost base. This matters for cash flow planning, setting budgets, and avoiding sudden spikes when wholesale prices rise. Business electricity tariff comparison across UK suppliers shows significant price variation sometimes 15–20% between the cheapest and most expensive fixed deals on the market at any given time.
Current Business Electricity Rates in the UK (2026)
Current business electricity rates sit at an average of 24p–26p per kWh for small and medium businesses, with standing charges between 40p–90p per day. These figures cover the commodity portion only. Non-commodity costs network charges, levies, and policy costs add a further 8p–12p per kWh on top.
When you compare business electricity prices UK-wide, the spread is wide. A restaurant in Manchester paying 27p per kWh may switch to a fixed deal at 23p per kWh and save over £1,200 a year on a 50,000 kWh consumption. A warehouse in Birmingham at 25p may find 22p fixed deals available through a full business energy prices comparison.
Business power prices vary by: contract length (longer contracts often carry a premium), meter type (half-hourly meters attract different rates), location (distribution network operator zones affect standing charges), and credit risk profile of your business.
Should I Fix My Business Energy Prices in 2026?
Fix if your contract ends within 3–6 months and your current rate is above market average. Here are the 4 key situations where fixing makes commercial sense:
Your renewal window opens soon. Most suppliers allow you to lock a new fixed rate 6 months before your contract ends. Starting a business energy prices comparison early gives you the widest choice.
You need budget certainty. Hospitality, retail, and manufacturing businesses with tight margins benefit most from fixed rates one energy price spike can wipe monthly profit.
Non-commodity costs are rising. Network charges and regulatory levies are forecast to increase through 2026–2027. Even if wholesale prices fall, your total bill may not. A fixed rate hedges against this structural cost increase.
You plan to stay at the same premises. A 2–3 year fixed contract only works if your business location and energy use stays broadly stable. Significant changes to usage or a site move can create complications mid-contract.
When You Should NOT Fix Business Energy Prices
Do not fix if any of the following apply to your business:
Your business is likely to relocate or downsize within 12 months.
If you are close to installing solar panels or battery storage, your consumption profile will change significantly.
Wholesale prices are at a historical peak, and forecasts show a clear downward trend with high confidence.
Your usage is highly variable season to season, and a half-hourly flexible tariff would better match your actual consumption.
In these cases, comparing business energy supplier's prices for short-term or flexible deals makes more sense than committing to a multi-year fixed rate.
Business Energy Prices Comparison: Fixed vs Variable vs Flexible
3 main tariff types are available to UK businesses, each suited to a different risk profile:
1. Fixed Rate Contract
Best for: SMEs that want cost certainty and simple budgeting.
Your unit rate does not change. You know what each kWh costs on day one of the contract. Business fixed rate electricity is the most common choice for small and medium businesses. Contract terms run from 12 to 48 months.
2. Variable Rate Contract
Best for: Businesses willing to take market risk in exchange for potential savings.
Rates follow the wholesale market and can rise or fall monthly. Variable tariffs offer no price certainty and carry the risk of significant bill increases if energy prices spike, as happened in 2021–2022 when wholesale gas prices rose by over 400%.
3. Flexible / Half-Hourly Contract
Best for: Large energy users (over 100,000 kWh/year) with sophisticated procurement capabilities.
Rates are drawn from the wholesale market at set intervals, allowing buyers to purchase energy in advance or on the day. Commercial electricity comparison tools can help large users model whether this approach suits their consumption pattern.
How to Compare Business Electricity Prices UK
To get an accurate business electricity rate comparison, gather these 5 data points before requesting quotes:
Annual consumption in kWh (from your current bill or smart meter data)
Current contract end date (so suppliers know your switching window)
Meter type: single-rate, Economy 7, or half-hourly
Business address and meter point administration number (MPAN)
Current supplier and tariff name
Use a business energy price comparison UK tool to run live quotes across multiple suppliers simultaneously. This takes under 5 minutes and shows you current market rates side by side. Contacting each supplier separately adds no value and wastes time the market rates are the same.
For gas, the process mirrors electricity. A full comparison of commercial electricity and gas gives you a combined picture of your total energy cost position.
What Drives Business Energy Prices in the UK?
5 main factors determine what you pay on a business energy contract:
Wholesale commodity prices. The price suppliers pay for gas and electricity on the wholesale market. This feeds directly into your unit rate, typically 40–50% of your total bill.
Network charges (Transmission and Distribution Use of System). Fees for using the national grid and local distribution network. These account for roughly 20–25% of a business's electricity bill and are rising.
Environmental and policy levies. Costs such as the Contracts for Difference (CfD) scheme, Renewables Obligation (RO), and Feed-in Tariffs (FiT) are passed on to business customers. These are expected to increase as the UK transitions to net zero.
Supplier margin and credit risk. Suppliers price in their own operating costs and assess your business credit profile. A strong credit history can reduce the margin added to your quote.
Contract length and timing. Signing a 3-year deal when wholesale prices are high can lock in an expensive rate. Timing your business energy prices comparison to coincide with a period of lower wholesale prices can reduce costs.
Business Energy Prices: Key Numbers to Know
These figures apply to typical UK SMEs in 2026:
Average business electricity unit rate: 24p–26p per kWh
Average business gas unit rate: 6.5p–8.5p per kWh
Average electricity standing charge: 45p–85p/day
Average gas standing charge: 25p–55p/day
Cheapest fixed electricity deals (small business, 1-year): from 21p per kWh
Price difference between the cheapest and most expensive supplier on same profile: up to 20%
These rates exclude VAT. Most businesses pay 20% VAT on energy. Businesses using less than 33 kWh of electricity per day or less than 145 kWh of gas per day qualify for the reduced 5% VAT rate. Check your current business electricity rates against these benchmarks to identify whether you are overpaying.
How to Switch Business Energy Supplier
The switch process for business energy takes 4 steps:
Run a comparison. Use a business energy prices comparison tool to see live quotes. Enter your MPAN, consumption, and contract end date.
Choose a deal. Select the tariff that balances rate, contract length, and supplier reliability. Check Trustpilot reviews for service quality alongside price.
Give notice. Most business energy contracts require 30–90 days notice before your end date. Check your contract terms. Missing this window can roll you onto a deemed or out-of-contract rate typically 30–50% above standard tariffs.
New supplier takes over. The switch happens at the meter level. No interruption to your energy supply. Your new fixed rate starts from the agreed start date.
Compare business energy suppliers prices at least 3 months before your contract ends to avoid rolling onto out-of-contract rates.
Frequently Asked Questions
What is the average business electricity rate per kWh in the UK?
The average is 24p–26p per kWh for small and medium businesses on standard fixed contracts in 2026. Rates vary by contract length, consumption volume, meter type, and supplier. Running a live business electricity tariff comparison shows the actual current rates available for your specific business profile.
Should I fix my business energy prices now or wait?
Fix now if your contract ends within 6 months and wholesale prices are not at a confirmed peak. Non-commodity costs network charges and levies are rising regardless of what happens to wholesale prices. Waiting to fix exposes you to both commodity and non-commodity cost increases. A business energy prices comparison today shows whether current fixed rates are competitive.
How long should a fixed business energy contract be?
A 1–2 year fixed contract suits most SMEs. Longer contracts (3–4 years) lock in price certainty but reduce flexibility. They make sense only if the rate is genuinely lower than 2-year equivalents and your business operations are stable. Compare business energy prices across multiple term lengths before committing.
Can I exit a fixed business energy contract early?
Yes, but early exit may involve termination fees. Unlike domestic energy, business contracts can include significant break clauses or termination costs. Some contracts charge the full remaining contract value. Always read exit terms before signing. If your business is at risk of relocation or closure, a shorter contract or rolling deal reduces this risk.
What is the difference between fixed and variable business energy?
Fixed means your unit rate does not change. Variable means it can rise or fall with the market. Fixed contract energy gives price certainty your rate per kWh is the same on day one and day 365. Variable tariffs can offer savings when wholesale prices drop, but expose you to sharp increases. Most UK businesses choose fixed rates for budget stability.
Does a fixed rate mean my bills stay the same every month?
No. Fixed rate means your unit rate is locked, not your monthly bill amount. Your bill changes based on how much energy you use. In winter, consumption increases and your bill rises even on a fixed tariff. The advantage is that each kWh costs the same throughout you eliminate price risk while usage-based variation remains.
How do I compare business energy suppliers prices effectively?
Use an independent comparison tool that shows live quotes from multiple suppliers simultaneously. Enter your MPAN, annual consumption in kWh, and contract end date. A proper compare business energy suppliers prices tool updates in real time and shows unit rates, standing charges, and contract terms side by side. This takes 5 minutes and often reveals savings of 10–20% over your current deal.
