“Commercial electricity rates” is the phrase larger UK firms, US-headquartered subsidiaries and property managers reach for when they want a benchmark on what a serious volume of power should cost. The numbers behind the phrase are not the same as the per-kWh quotes a corner shop sees, so this guide focuses on commercial-scale pricing: 50,000 kWh and up, half-hourly settled meters, and multi-site portfolios. For a smaller-business per-kWh deep dive, see our sister article on business electricity prices per kWh in the UK 2026.
In 2026 the wholesale curve is roughly flat to mid-2027 and gently rising into 2028-29, which means commercial buyers locking in 24-36 month fixes are getting better blended rates than buyers taking 12-month tactical deals. The detail below shows where you fall on the rate spectrum and how to pull yours down.
What “commercial” actually means in UK utility terminology
UK suppliers split non-domestic customers into three loose tiers, and each tier prices differently:
- SME (small & medium enterprise): typically anything under 100,000 kWh/year on a profile-class 03-04 meter. Priced from rate cards refreshed weekly.
- Commercial / I&C (Industrial & Commercial): roughly 100,000-2,000,000 kWh/year, often half-hourly settled, priced bespoke against the wholesale curve plus pass-through non-commodity costs.
- Major / strategic: 2,000,000 kWh+ and multi-site portfolios. Negotiated directly via a procurement team or Third Party Intermediary (TPI), often using flexible / basket / risk-managed contracts.
“Commercial electricity rates” usually maps to the middle tier. If you are reading this for a single shop or office under 25,000 kWh, you are technically a micro or SME — the SME rate guidance later in this article will fit you better.
UK commercial electricity rates by usage band, 2026
Rates below are blended unit-rate quotes from Q1 2026, all-in (commodity + non-commodity) but excluding VAT and CCL. Standing charges are quoted separately because they vary much more between meter capacity bands than between suppliers.
All figures are blended quote ranges from comparison data Q1 2026. Excludes VAT (5% reduced or 20% standard) and Climate Change Levy. Standing charges step up sharply at the half-hourly threshold because of capacity and Distribution Use of System (DUoS) availability charges.
Two patterns matter here. First, the unit rate falls as you scale up — about 1.5p/kWh for every doubling of consumption. Second, the standing charge grows almost linearly with capacity, so a 1MVA site can pay £900-£9,000/year in fixed daily charges before consuming a single kWh. For sites that are open seasonally (hospitality, schools, holiday lets), this is a major cost driver and is sometimes worth chasing a no-standing-charge business energy tariff to avoid.
Commercial electricity rates by supplier, 50,000 kWh business
Below is the blended unit rate quoted by major UK commercial suppliers for a 50,000 kWh single-site office on a 36-month fix in Q1 2026. Quotes assume a clean credit profile and a renewal window at least 60 days out.
The headline gap between cheapest and most expensive is 1.5p/kWh, which sounds small but is £750/year on a 50,000 kWh business and £3,750 over the 36-month contract. For larger commercial users, the gap widens because non-commodity components are more negotiable. For background on supplier strengths and weaknesses, our UK business energy suppliers guide and our Big Six business energy comparison rank suppliers by service, credit and renewable mix as well as price.
Regional variation in UK commercial electricity rates
The UK is split into 14 Distribution Network Operator (DNO) regions, each with its own DUoS (Distribution Use of System) and TUoS (Transmission Use of System) charges. Wholesale electricity costs the same nationally, but the network charge stack differs by 1-3p/kWh between cheapest and dearest regions.
- Cheapest networks (commercial): East Midlands, Yorkshire, Eastern. These have high transit volume and well-amortised infrastructure.
- Average networks: London, Southern, North West, West Midlands, South Wales.
- Most expensive networks: North Scotland (SSEH), South West (Western Power), Merseyside & North Wales. North Scotland in particular is hit by remote-network costs that add 1.5-2p/kWh.
If you operate the same site footprint across multiple regions, expect a 6-12% rate spread between locations even with identical suppliers. That is normal and not a sign of getting a worse deal in one region. The regional spread is set by Ofgem-approved DUoS / TUoS charging methodology and changes annually each April.
What drives a commercial electricity rate
A commercial electricity unit rate is built from five layers stacked on top of each other:
- Wholesale commodity (40-55%): the day-ahead and forward power market on Nord Pool / EPEX UK. Sits roughly £75-£95/MWh in 2026 for forward 2027-28.
- DUoS & TUoS (15-20%): distribution and transmission network charges, set by Ofgem and your regional DNO.
- BSUoS & Capacity Market (5-10%): the Balancing Services Use of System charge plus the cost of the Capacity Market auction. BSUoS reformed to a fixed daily charge in April 2023.
- Renewables Obligation, Contracts for Difference, Feed-in Tariff (15-20%): the legacy and current renewable subsidy schemes, recovered from suppliers and passed to you.
- Supplier margin + broker margin (3-8%): how the supplier and (if used) the TPI cover their cost-to-serve and shareholder return. See our breakdown of business energy broker fees explained.
Because the non-commodity stack is roughly 45-60% of the unit rate, the wholesale price you see on the news has a smaller per-kWh effect than people expect. A 20% drop in wholesale only delivers an 8-11% drop in delivered commercial rate, all else equal.
How to negotiate as a larger commercial buyer
Anyone above 50,000 kWh has real negotiating power. The leverage drops below that, and rises sharply above 250,000 kWh. The five tactics that move the needle most:
1. Quote 4-6 months before renewal
Suppliers price fixed contracts off forward curves that are published daily. Quoting too early (12+ months out) gets a risk premium baked in. Quoting too late (under 60 days) gets the supplier’s “out-of-contract” rate or a penal short-window quote. The Goldilocks zone is 4-6 months out.
2. Run a true competitive tender
For commercial volume, get at least 3 supplier quotes plus 1 broker. Suppliers know they are bidding against each other and sharpen pencils. The standard tender pack includes 12 months of half-hourly data, MPAN(s), current contract end dates and any decarbonisation or REGO requirements.
3. Use a Letter of Authority correctly
A signed Letter of Authority (LOA) lets your broker pull industry data, see your real consumption profile and quote against your true load shape. Without it, suppliers price defensively. Sign one, but only with a single broker per tender to avoid duplicate-quote pollution.
4. Ask for a transparent broker-fee disclosure
Reputable TPIs disclose their per-kWh uplift in writing before you sign. For commercial volumes (50k+ kWh) the typical uplift is 0.05-0.30p/kWh; anything above 0.5p/kWh on commercial volume is a red flag. Ask for the uplift in pence-per-kWh, not percentage of bill.
5. Push for non-commodity pass-through on volumes over 250k kWh
At larger scale, you can request a “pass-through” structure where you pay the actual non-commodity costs as published by Ofgem and your DNO, rather than a fixed all-in number. This works in your favour when network charges fall and is a fairer reflection of what you are paying for. See our business energy procurement guide for the strategic options at this scale.
Worked example: 250,000 kWh single site, City of London
A 250,000 kWh per year office in EC2 with a profile class 04 max-demand meter, 220 kVA capacity, 9-6 weekday consumption profile:
- 36-month fix from a competitive tender of 4 suppliers in Q1 2026: 21.4p/kWh blended unit rate.
- Standing/availability charge: £3.20/day (£1,168/year).
- Annual electricity cost: 250,000 × 0.214 = £53,500 + £1,168 standing = £54,668 ex-VAT, ex-CCL.
- CCL @ 0.775p/kWh = £1,938. VAT @ 20% = £11,321. Gross total: ~£67,927/year.
The same business on its previous out-of-contract rate of 32p/kWh + £4.50/day standing was paying £81,642 ex-VAT, ex-CCL. Net annual saving from a competitive tender: £26,974, or 33%. This level of saving is realistic for any business above 100k kWh that has not retendered in the last 18 months.
Climate Change Levy and VAT on commercial electricity
Two compulsory tax lines appear on every commercial electricity bill:
- Climate Change Levy (CCL): 0.775p/kWh in 2025-26, applied to all business electricity. Charities and very low users (under 33 kWh/day average) are exempt. Read our breakdown of the CCL on business energy in 2026.
- VAT: 20% standard rate. Some businesses qualify for 5% reduced rate — charities, very low users (under 33 kWh/day) and those with 60%+ non-business use. See VAT on business energy bills for the qualification rules.
Commercial electricity rates outlook 2026-2028
Forward curves at the time of writing imply UK power prices roughly flat through 2026-27 with a 6-9% rise into 2028, driven by Hinkley Point C delays, North Sea gas tail-off and Capacity Market auction tightness. The practical translation:
- If renewing in 2026, a 24-36 month fix locks in roughly today’s rate before the 2028 step-up.
- If renewing in 2027, a 12-month fix gives flexibility to retest the market once the 2028 jump is priced.
- Pass-through and basket contracts beat fixes if your treasury can stomach 5-10% monthly volatility.

Frequently Asked Questions
Most UK commercial electricity rates in 2026 fall between 18p and 26p per kWh, with micro-businesses paying 26-30p, mid-sized SMEs 20-25p and large half-hourly industrial sites 15-20p. Standing charges add 35p to £3.50 per day, growing roughly linearly with site capacity.
They overlap but the words are not identical. “Business electricity” covers everything from a corner shop upwards. “Commercial electricity” usually implies a larger user (50,000 kWh and above), often half-hourly settled, with bespoke pricing rather than rate-card pricing. Smaller users will get better information from our business electricity prices per kWh guide.
Wholesale electricity is one national price, but Distribution Use of System (DUoS) and Transmission Use of System (TUoS) charges differ by region because each Distribution Network Operator (DNO) has different infrastructure costs. The spread between cheapest and dearest region is roughly 1-3p/kWh. North Scotland and the South West are typically dearest; East Midlands and Yorkshire cheapest.
Quote 4-6 months before renewal, run a competitive tender across at least 3 suppliers, sign a single Letter of Authority with one broker, ask for a transparent broker-fee disclosure in p/kWh, and consider pass-through non-commodity structures if you are above 250,000 kWh.
With the wholesale curve flat through 2026-27 and a 6-9% step-up implied for 2028, 24-36 month fixes typically deliver the best blended commercial rate. A 12-month tactical fix wins only if you actively monitor the wholesale market and re-tender at the next dip.
No. Quoted unit rates are commodity + non-commodity and exclude VAT and CCL. CCL adds 0.775p/kWh and VAT adds 5% or 20% on top of the post-CCL total. Check the VAT on business energy bills guide to see if you qualify for the reduced 5% rate.
