- Average UK business electricity: 24.5p/kWh in 2026 - down from 2023 peak but still 40% above pre-crisis levels
- Compare total annual cost, not just unit rate - standing charges of £0.60–£1.20/day add £219–£438/year before any usage
- Small businesses pay 15–25% more per kWh than large enterprises - volume discounts and direct procurement give larger firms significant advantages
- Industry matters: hospitality and manufacturing pay the most - energy-intensive sectors face 30–50% higher bills than equivalent-sized office businesses
- Switch 2–3 months before contract end - rollover rates are typically 20–40% higher than negotiated renewal prices
How Much Does Business Energy Cost in 2026?
Business electricity costs 23–27p per kWh for small businesses and 20–25p per kWh for larger businesses in February 2026. Business gas costs 5.9–6.6p per kWh for small businesses. The average small business pays around £7,085 per year for combined electricity and gas, while micro businesses pay around £3,660.
| Business Size | Annual Usage (Elec) | Electricity (p/kWh) | Gas (p/kWh) | Combined Annual Bill |
|---|---|---|---|---|
| Micro (1–9 staff) | 7,500–10,000 kWh | 25–30p | 7.0–7.6p | £3,660 |
| Small (10–49 staff) | 15,000–25,000 kWh | 23–27p | 5.9–6.6p | £7,085 |
| Medium (50–249 staff) | 25,000–50,000 kWh | 21–26p | 5.4–6.6p | £14,152 |
| Large (250+ staff) | 55,000–100,000+ kWh | 20–25p | 5.2–7.4p | £19,039 |
These figures represent fixed contract rates from January–February 2026, based on data from Uswitch, Bionic, and DEIS government statistics. Rates exclude Climate Change Levy (CCL) where applicable. Businesses on deemed or out-of-contract rates may be paying significantly more — up to 40p/kWh for electricity.
Business Electricity Rates by Supplier
Electricity rates range from 22.9p/kWh (Yu Energy) to 28.1p/kWh (British Gas) for small businesses on fixed contracts. However, the cheapest unit rate doesn’t always mean the lowest bill — standing charges vary from 34.7p to 105.9p per day, which can add £125–£387/year to your total cost.
| Supplier | Electricity (p/kWh) | Standing Charge (/day) | Gas (p/kWh) | Gas Standing (/day) |
|---|---|---|---|---|
| Yu Energy | 22.9 | 105.9 | 6.8 | 37.3 |
| ScottishPower | 23.1 | 70.9 | 6.3 | 30.8 |
| Smartest Energy | 24.4 | 69.0 | 5.0 | 99.5 |
| Valda Energy | 24.2 | 88.2 | 6.6 | 41.6 |
| Yorkshire Gas & Power | 24.3 | 70.0 | 5.4 | 54.9 |
| EDF Energy | 26.3 | 54.6 | 6.8 | 48.5 |
| EON Next | 27.4 | 34.7 | 6.4 | 30.0 |
| British Gas | 28.1 | 47.1 | 7.3 | 57.3 |
The standing charge trap: Yu Energy offers the cheapest unit rate (22.9p) but the highest electricity standing charge (105.9p/day = £387/year). For a micro business using 10,000 kWh/year, this adds up to £2,677 total. EON Next charges 27.4p/kWh but only 34.7p/day standing charge (£127/year), making the total £2,867. The difference is just £190 — much less than the unit rate alone suggests.

What Affects Business Energy Costs?
Six main factors determine your business energy costs: consumption volume, contract type, business size, industry, location, and payment method. The biggest variable is contract type — businesses on deemed (out-of-contract) rates pay up to 60–80% more than those on fixed contracts.
| Factor | Impact on Cost | What You Can Control |
|---|---|---|
| Consumption volume | Higher volume = lower unit rate (bulk discount) | Reduce usage with efficiency measures |
| Contract type | Fixed saves 20–40% vs deemed/variable | Always be on a fixed contract |
| Business size | Larger businesses negotiate better rates | Use a broker for volumes over 50,000 kWh |
| Industry | Energy-intensive sectors (CCL + EII exemptions) | Check for industry exemptions |
| Location | Regional network charges vary by 10–15% | Limited control (network-dependent) |
| Payment method | Direct debit saves 5–10% vs quarterly bills | Switch to monthly direct debit |
The single most impactful thing you can do is never be on a deemed rate. When your contract expires, you automatically move to the supplier’s default tariff, which is typically 60–80% higher than a negotiated fixed rate. Set a reminder 3 months before your contract end date to start comparing new deals.
Fixed vs Variable vs Deemed Rates
Fixed-rate contracts lock in a price per kWh for 1–5 years — giving cost certainty and usually the best rates. Variable rates fluctuate with wholesale prices — cheaper when markets fall, risky when they rise. Deemed rates are the default when you have no contract — always the most expensive option.
| Contract Type | Typical Electricity Rate | Best For | Risk Level |
|---|---|---|---|
| Fixed (1–2 year) | 23–27p/kWh | Budget certainty, most businesses | Low |
| Fixed (3–5 year) | 25–30p/kWh | Long-term stability, risk-averse | Low (but can’t benefit from falling prices) |
| Variable / flexible | 20–35p/kWh | Large businesses with active management | Medium–High |
| Deemed (out-of-contract) | 35–45p/kWh | Nobody — always avoid | Very High |
| Green / renewable | 24–29p/kWh | ESG-conscious businesses | Low |
For most SMBs, a 1–2 year fixed contract is the best balance of price certainty and flexibility. Longer contracts (3–5 years) offer stability but lock you in if prices fall further. Variable/flexible contracts are only suitable for businesses with dedicated energy procurement teams who can actively manage wholesale price exposure.
What’s Included in Your Energy Bill?
Your business energy bill includes more than just the electricity and gas you use. Non-commodity costs (network charges, environmental levies, and taxes) make up 40–60% of the total bill. Understanding these components helps you identify where savings are possible and where costs are fixed.
| Bill Component | % of Total Bill | Can You Reduce It? |
|---|---|---|
| Wholesale energy cost | 35–45% | Yes — by choosing the right contract/supplier |
| Network charges (DUoS, TNUoS) | 20–25% | No — set by network operator |
| Environmental levies (RO, FiT, CFD) | 10–15% | Partial — EII exemptions for qualifying industries |
| Standing charge | 5–10% | Yes — compare suppliers (varies significantly) |
| VAT (20%) + CCL | 10–15% | Partial — some businesses qualify for reduced VAT (5%) |
| Supplier margin | 3–5% | Yes — negotiate or switch supplier |
Businesses registered for VAT can reclaim the VAT on energy bills. Charities, non-profits, and domestic properties used for business may qualify for the reduced 5% VAT rate instead of 20%. Sole traders working from home can claim a proportion of energy costs as a business expense. Check with your accountant to ensure you’re claiming all eligible reliefs.
How to Reduce Your Business Energy Costs
Most businesses can save 15–30% on energy costs by switching supplier, negotiating at renewal, and making basic efficiency improvements. The average SMB overpays by £1,000–£3,000/year because they stay on rolled-over contracts without comparing alternatives.
- Switch supplier before your contract ends. Deemed rates are 60–80% higher than fixed contracts. Set a reminder 3 months before expiry to start comparing.
- Get at least 3 quotes. Rates vary by 20–30% between suppliers for the same usage profile. Use our free comparison form above or contact an independent broker.
- Consider using a broker. Energy brokers access wholesale rates not available to businesses directly. They’re typically free to use (paid by suppliers). See our top 10 UK energy brokers.
- Pay by monthly direct debit. This saves 5–10% compared to quarterly billing and avoids late payment charges.
- Submit regular meter readings. Estimated bills often overcharge. Smart meters eliminate this issue entirely.
- Reduce consumption. LED lighting (saves 50–80%), smart thermostats (saves 10–15%), equipment timers, and insulation upgrades all reduce kWh usage directly.
- Check for VAT relief. Charities and some small businesses qualify for 5% VAT instead of 20% on energy, saving up to 15% on the total bill.
For businesses spending over £10,000/year on energy, even a 10% saving is £1,000+ back in your pocket. The comparison and switching process takes 10–15 minutes and there are no disruption to supply when you switch — your meters, pipes, and electricity supply all remain the same.

Business Energy Costs by Industry
Energy costs vary widely by industry. A typical office pays £3,000–£7,000/year, while a restaurant or pub pays £8,000–£15,000/year due to commercial kitchens and heating. Manufacturing and warehousing can exceed £50,000/year and often qualify for negotiated rates and CCL exemptions.
| Business Type | Annual Energy Bill | Main Cost Drivers |
|---|---|---|
| Home office / sole trader | £500 – £1,500 | Proportion of domestic bill |
| Small office (5–10 staff) | £3,000 – £7,000 | Lighting, heating, IT equipment |
| Retail shop | £4,000 – £10,000 | Lighting, HVAC, refrigeration |
| Restaurant / pub | £8,000 – £15,000 | Commercial kitchen, ventilation, heating |
| Salon / spa | £3,000 – £8,000 | Hot water, dryers, heating |
| Warehouse | £5,000 – £20,000 | Lighting, loading, refrigeration |
| Manufacturing | £20,000 – £100,000+ | Machinery, compressed air, process heat |

How Energy Prices Have Changed
Business electricity prices peaked at 45–50p/kWh in Q4 2022 during the energy crisis, compared to 8–10p/kWh before 2021. In February 2026, rates have settled to 23–27p/kWh for small businesses — still 2.5× the pre-crisis level but down 40–50% from the peak. Gas has recovered more strongly.
| Period | Small Business Electricity | Small Business Gas |
|---|---|---|
| Pre-2021 | 8–10p/kWh | 2.5–3.5p/kWh |
| 2022 (crisis peak) | 45–50p/kWh | 12–15p/kWh |
| 2023 | 32–38p/kWh | 8–9p/kWh |
| 2024 | 28–33p/kWh | 6.5–8p/kWh |
| Feb 2026 | 23–27p/kWh | 5.9–6.6p/kWh |
Wholesale gas prices have dropped significantly, which is feeding through to lower business gas rates (now below 7p/kWh for most businesses). Electricity is slower to fall because non-commodity costs (network charges, green levies) account for a larger share of the bill. Analysts expect gradual reductions through 2026–2027 but a return to pre-2021 levels is unlikely.
Should You Use an Energy Broker?
Energy brokers are worth considering if your business spends over £5,000/year on energy. They access wholesale rates not available to businesses directly, and their service is typically free to use (they earn a commission from the supplier). A good broker can save 10–25% compared to going direct.
When to use a broker:
- Your annual energy spend exceeds £5,000
- You don’t have time to compare multiple suppliers yourself
- You want access to rates from suppliers who don’t sell direct to SMBs
- Your contract is due for renewal and you want expert negotiation
Watch out for: some brokers lock you into their service with auto-renewal clauses, meaning they earn commission every time your contract renews. Always check whether the broker’s Letter of Authority includes auto-renewal and ensure you can terminate the arrangement at any time.

How to Switch Business Energy Supplier
Switching business energy supplier takes 2–6 weeks and involves no disruption to your supply. You need your current supplier name, contract end date, annual consumption (kWh), and meter type (MPAN for electricity, MPRN for gas). The new supplier handles the transfer — your pipes, wires, and meters all stay the same.
- Check your contract end date — most contracts require 30–90 days’ notice. Start comparing 3 months before expiry.
- Gather your details — MPAN/MPRN numbers (on your bill), annual consumption, current rate, and contract end date.
- Compare quotes — use our comparison form above or contact 3+ suppliers/brokers directly.
- Accept the best offer — sign the contract (usually digital). The new supplier initiates the transfer.
- Supply transfers automatically — on your contract end date. There is zero interruption to your electricity or gas.
Important: If you’re still within a fixed contract, check for early termination fees before switching. These can be several hundred pounds and may wipe out any savings. Wait for the contract end date unless the termination fee is lower than the savings from switching.
