Business electricity rates by usage level
Your per-unit rate depends heavily on how much electricity your business uses. Here's a rough guide based on current UK market conditions:
| Usage Level | Annual kWh | Typical Unit Rate | Typical Annual Cost |
|---|---|---|---|
| Small office / shop | 5,000 – 15,000 | 26 – 32p/kWh | £1,500 – £4,500 |
| Medium business | 15,000 – 50,000 | 22 – 28p/kWh | £3,500 – £13,000 |
| Large / multi-site | 50,000 – 250,000+ | 18 – 24p/kWh | £10,000 – £55,000+ |
We analyse your usage. We negotiate your rates.
Most businesses overpay because they don't have the time — or the data — to compare like-for-like. We pull your actual half-hourly usage from the supplier, model your true cost across the market, and present the top 3 options with a clear cost breakdown.
- Real consumption data — not estimates from your last bill
- Side-by-side comparison — top 3 options with full cost breakdown
- Hand-managed switch — we handle paperwork, meter reads and supplier liaison

Best business electricity prices in the UK for 2026
An honest, supplier-agnostic guide to the best business electricity rates in the UK — what drives the price, the tariff types worth knowing, and how to lock in the lowest unit rate for your meter.
How are the best business electricity prices set in the UK?
The best business electricity prices available to you depend on five things: how much electricity you use a year (your annual consumption in kWh), your meter type (Profile Class 03/04 for SMEs, half-hourly for larger sites), your postcode (DNO region affects standing charges and unit rates), your contract length, and where the wholesale electricity market sits on the day you sign. Suppliers buy electricity on the wholesale market, add network charges, environmental levies and a small margin, then publish a unit rate per kWh and a daily standing charge.
For a typical UK SME in 2026, the best business electricity rates UK suppliers are offering sit between 22 p and 28 p per kWh on a 24-month fix, with daily standing charges of 35 p – 65 p. Larger sites with annual usage above 50,000 kWh routinely access rates of 18 p – 24 p per kWh. The cheapest headline rate isn't always the best deal — standing charges, exit fees, contract terms and supplier service all matter when calculating your true annual cost.
Best business electricity rates UK 2026 — by usage band
The table below shows indicative best business electricity prices we're currently securing for SMEs across the UK. Your actual quote depends on the wholesale market on the day, your meter and your DNO region — these are realistic worked examples for budgeting purposes.
| Annual usage | Best unit rate (p / kWh) | Standing charge (p / day) | Indicative annual cost |
|---|---|---|---|
| Micro business — up to 5,000 kWh | 27 – 30 p | 40 – 50 p | £1,500 – £1,800 |
| Small business — 5,000 – 15,000 kWh | 24 – 28 p | 40 – 55 p | £1,500 – £4,500 |
| Medium business — 15,000 – 50,000 kWh | 22 – 26 p | 50 – 65 p | £3,500 – £13,000 |
| Large / multi-site — 50,000+ kWh | 18 – 24 p | varies | £10,000 – £55,000+ |
Indicative as of May 2026. Quotes will reflect live wholesale prices on the day. Half-hourly metered sites are quoted bespoke.

"Best business electricity tariff" doesn't mean the same thing for every business. The right tariff depends on how predictable your usage is, your appetite for risk, and how long you want price certainty. Here's the plain-English version:
Fixed-rate business electricity tariff (most popular)
Lock in a single unit rate and standing charge for 12, 24 or 36 months. The best fixed business electricity rates in the UK for 2026 are typically 24-month deals — long enough to ride out short-term wholesale spikes, short enough to retender competitively. 90% of UK SMEs are on a fixed tariff and most should be.
Pass-through / flexible business electricity tariff
You pay the wholesale price plus a fixed margin and pass-through costs. Best suited to high-consumption businesses (>250,000 kWh / year) with the operational ability to monitor wholesale movements. Cheaper than a fix when wholesale is calm; exposed when wholesale spikes.
Deemed / out-of-contract rates (avoid)
If your supplier hasn't received notice from you before your contract ended, you've been rolled onto a deemed tariff. These are the most expensive business electricity rates in the UK — typically 35 – 50% above the best fixed rates. If you've moved into new premises and inherited a meter, you'll also be on deemed rates by default.
Green / REGO-backed business electricity tariff
The same supply, but the supplier matches your usage with electricity from certified renewable sources (REGO certificates) and produces a CSR-ready certificate. Costs roughly 0 – 4% more than a comparable brown tariff in 2026 — a meaningful sustainability lever for very small additional cost.
How to actually get the best business electricity prices
Three rules cover 95% of the saving:
- Compare on full annual cost, not headline unit rate. A 23 p unit rate with a £1.20 daily standing charge is more expensive than a 25 p unit rate with a 50 p standing charge for most small businesses.
- Lock in 6 – 12 months before your contract ends. Suppliers let you sign forward contracts up to 12 months early. If wholesale prices drop in that window, sign now. If they rise, you've protected yourself.
- Use real consumption data — not estimates. Half-hourly data from your meter shows your true profile. We pull this directly from your supplier and model your true cost across every supplier in the market.
Why we get cheaper business electricity rates than going direct
Suppliers reserve their best business electricity prices for brokers because we deliver scale. We aggregate hundreds of UK businesses into commercial relationships with the major suppliers (British Gas Business, EDF Business, Octopus Energy, SmartestEnergy, SSE, E.ON Next Business, Total Energies and Pozitive Energy among them), which gives us access to rates not advertised on the open market. We also know which supplier is competitive in your DNO region this week — that varies more than people realise.
Business energy is the gas and electricity contracted by limited companies, sole traders, charities and public bodies in the UK. Unlike domestic supply, business energy is not covered by the Ofgem price cap, contracts are firm for the term, and unit rates can vary by 30–50% between the cheapest and most expensive supplier on the same day. That spread is exactly why running a comparison saves money — and why deemed rates (the rate suppliers charge when no contract is in place) are usually 30–50% above the open market.

Why compare business energy with Connection Technologies
We are an independent UK-based business energy broker, not a price comparison site and not a single supplier. That distinction matters: we run quotes across the entire 40+ UK business energy supplier market, then sort them by total annual cost using your real consumption rather than estimates. The result is a quote you can sign the same day, with no obligation if a better number turns up tomorrow.
- 40+ suppliers compared — including British Gas, EDF, E.ON Next, Octopus Energy, ScottishPower, SSE, Drax, SEFE Energy, Pozitive, Smartest, Yu, Crown Gas & Power, Total Energies, Opus, Conrad, CNG, Haven Power, Engie, Statkraft, Good Energy and Ecotricity.
- Average savings of 15–35% for SMEs switching off deemed or out-of-contract tariffs onto a properly negotiated fixed contract.
- Free Letter of Authority service — we draft, send and chase the LOA so suppliers release real (not estimated) quotes against your meter. Read more on how a Letter of Authority works.
- UK-based account managers — one named human handles your account, monitors your contract end date and runs your renewal automatically. No call-centre script, no offshore handover.
- Zero cost to your business — suppliers fund the service through a small standard broker uplift on the unit rate (typically 0.1–0.5p/kWh for SMEs). We disclose every fee in writing before you sign — details on our broker fees explained guide.
- No spam, no sales pressure — we only contact you when there is something useful to share: a better quote, a renewal window, or a regulatory change that affects your bill.
Whether you run a single corner shop on a 4,000 kWh micro meter or a 200-site portfolio with a half-hourly settlement, we quote the right tariff against the right meter. For multi-site procurement specifically, see our multi-site meters guide.

Indicative best contracted rates verified Apr 2026 from supplier rate cards plus our quote book. SME band shown (5,000 – 50,000 kWh / yr). Larger users (50,000+ kWh) typically secure 2 – 4 p/kWh below the rates above. Get a live quote in 60 seconds for the actual best business electricity prices on your meter today.
Three patterns worth knowing before you sign:
- The cheapest unit rate isn’t always the best deal. A 22 p / kWh rate with a 65 p / day standing charge is more expensive than a 24 p rate with a 35 p standing charge for any SME using under 25,000 kWh / yr. We always rank suppliers on total annual cost, not headline pence.
- Best-rate suppliers change weekly — depending on the wholesale market, your DNO region and whether the supplier is in an acquisition window. A supplier topping the league table this week often slips by 2 – 3 places next week.
- Standing charges and exit fees matter more than most people realise. Some of the cheapest headline rates come with 12-month-extended exit clauses. We surface every commercial term before you sign.

UK business electricity deemed rates by supplier (Q1 2026)
If you let a contract end without signing a new one, you fall onto the supplier’s deemed rate — a contract you never agreed to, on terms set entirely by the supplier. Deemed rates are typically 30–50% above the same supplier’s best contracted rate, exist to nudge you into renewing, and are perfectly legal. The good news: there is no exit fee on a deemed contract, so you can switch the day you spot you are on one. The full league table for Q1 2026 is below.
Deemed rates verified Apr 2026 from supplier rate cards. Always check the latest published rate before signing. Deemed and out-of-contract rates change quarterly — we keep our copy of every supplier’s rate card on file. For the back-story on why these rates exist, read our deemed contracts guide.
How to switch business energy in 6 steps
Switching is faster and simpler than most business owners assume. Here is the short version — for the full walk-through with screenshots and timing benchmarks see our step-by-step business energy switch guide.
- Diary your renewal window 6 months before contract end. Most contracts have a 1–6 month renewal window in which you can sign without paying an early-termination fee.
- Pull a recent bill. We need MPAN/MPRN, supplier name, contract end date and 12 months of consumption in kWh.
- Sign a Letter of Authority with us. The LOA is a one-page form authorising us to talk to suppliers on your behalf and pull real (not estimated) tariffs.
- Compare 40+ suppliers in one go — no chasing each supplier yourself, no callback queues. We sort by total annual cost and present the best 3–5.
- Sign your chosen contract electronically. Switch happens automatically on your contract end date with zero interruption to supply.
- Validate the first invoice. Around 15% of new contracts get billed wrong in month one — we check unit rate, standing charge, VAT band and CCL line for you.
How to find the cheapest business energy
The cheapest contract for a 4,000 kWh corner shop in Manchester is rarely the cheapest contract for a 400,000 kWh distribution centre in Bristol — “cheapest supplier” is a myth. Here are the five tactics that genuinely shave money off your unit rate, drawn from our cheapest business energy guide:
- Quote real consumption, not estimated. Estimating low gets a low quoted unit rate that the supplier raises when they see real usage. Pull 12 months of meter data first.
- Apply for half-hourly settlement if your peak demand is approaching 100 kW. Voluntarily moving to HH usually shaves 2–4p/kWh — see our half-hourly meters guide.
- Apply for the 5% reduced VAT rate if you qualify (under 33 kWh/day, charity, or 60%+ non-business use). The 15-percentage-point VAT saving usually beats the entire saving from switching supplier — full rules in our VAT on business energy bills guide.
- Pay by direct debit. Worth roughly 1–2% off the total bill versus BACS or invoice with most suppliers.
- Time the contract length to the wholesale curve. With wholesale flat or rising, lock 36–60 months. With wholesale falling, take 12–24 months and re-quote at renewal. The 2026 curve is roughly flat, so 24–36 months is the sweet spot.
Business gas vs business electricity — what is different
Business electricity has roughly 30 active suppliers in the UK and trades on a busier wholesale market, so spreads between cheapest and most expensive on a given day can hit 50%. Standing charges are higher but unit rates are lower in pence terms. Half-hourly settlement applies above 100 kW peak demand and gives access to sharper rates.
Business gas has fewer active suppliers (around 12 specialists plus the big multi-utility players) and a more concentrated wholesale market. Unit rates are much lower per kWh than electricity (typically 6–9p vs 18–30p) but standing charges are similar. Daily-metered gas (above 73,200 kWh / yr) follows different settlement rules. There is no automatic dual-fuel discount in the business market — quote gas and electricity separately to win the cheapest blended bill.
Top UK business energy suppliers in 2026
The UK has 40+ active business energy suppliers but ten dominate the SME market. Brief commentary below; deeper supplier reviews are linked from each name.
- British Gas Business — the UK’s largest business energy supplier with broad network coverage and the strongest service team for micro businesses. Read the British Gas Business review.
- EDF Energy — nuclear-heavy generation portfolio gives EDF some of the most stable wholesale costs and consistently competitive rates for medium and large users. Read the EDF Business review.
- E.ON Next — rebranded from npower’s SME book; strong digital onboarding and good for tech-savvy SMEs that want self-serve account management. Read the E.ON Next Business review.
- Octopus Energy for Business — the disruptor; sharp pricing, REGO-backed renewable as standard, and a slick portal. Increasingly competitive in the 5–100k kWh band. Read the Octopus Energy Business review.
- ScottishPower — Iberdrola-owned, strong renewable generation, dependable for medium SMEs.
- SSE Business — legacy Big Six brand, especially well represented in Scotland and the North East.
- Drax — specialist for large industrial and commercial users; strong on flex and pass-through contracts.
- SEFE Energy & Smartest Energy — consistently top of the league for half-hourly users above 250,000 kWh.

Business energy contract types
Five contract structures dominate the UK business energy market. Picking the right one is usually worth more than picking the cheapest supplier, especially above 100,000 kWh /yr. The deep-dive lives in business energy tariffs explained.
- Fixed — one unit rate and one standing charge for the term (typically 12, 24, 36, 48 or 60 months). Best for budgeting certainty; covers 90% of UK SMEs.
- Flexible / basket — you trade chunks of your annual volume on the wholesale market within a basket. Available above 1 GWh/year. Best when you have a procurement function and risk appetite.
- Pass-through — fixed wholesale rate plus pass-through of non-commodity costs (TNUoS, BSUoS, RO, FiT, CfD, etc). Useful when non-commodity costs fall but exposes you when they rise.
- Deemed — the default rate when no contract exists. Always 30–50% above the open market — fix it the day you spot it. More on deemed contracts.
- Out-of-contract — what most suppliers move you to after a contract ends and you fail to renew. Slightly cheaper than deemed but still 25–45% above market.

Frequently Asked Questions
For UK SMEs in Q1 2026 business electricity unit rates sit between 22p and 28p per kWh on a 24-month fixed contract, with a daily standing charge of 36–68p depending on consumption. Larger sites above 50,000 kWh/year typically secure 18p–24p per kWh. Deemed and out-of-contract rates run 30–50% higher — if you are paying above 35p/kWh you are almost certainly on a deemed tariff.
There is no single cheapest supplier — the leaderboard shifts every quarter as suppliers refresh their hedging. For micro users (under 5,000 kWh) British Gas Lite, EDF Simply Online and Yu Energy lead in 2026. For SMEs (5–50k kWh) Octopus Energy for Business, Yu Energy, Pozitive and Crown Gas & Power win most quotes. For large users (50k+ kWh) SmartestEnergy, SEFE Energy and Drax dominate. Get a 60-second quote for your specific meter.
The quote itself takes 60 seconds. The full switch typically completes in 2–6 weeks (4 weeks is most common) with zero interruption to your gas or electricity supply. The new supplier handles meter reads and the technical handover with the network operator. You can sign a forward contract up to 12 months before your current one ends, locking in today’s rates without affecting your current supply.
A deemed rate is the unit rate and standing charge a supplier charges when no contract is in place — typically because you moved into a property and never signed a contract, or your contract ended and you did not renew. Deemed rates are usually 30–50% above the same supplier’s best contracted rate. There is no exit fee on a deemed contract, so you can switch the day you discover you are on one.
Yes — a Letter of Authority (LOA) is required to let a broker like Connection Technologies talk to suppliers on your behalf and pull real tariffs against your meter. Without an LOA you only get estimates. Our LOA is a one-page form, free, and limited in scope to energy procurement. Read more in our LOA guide.
For 90% of UK SMEs, a fixed-rate contract is the right choice — it gives total budget certainty for the term and locks in your rate against future wholesale spikes. Flexible (basket) contracts only make sense above 1 GWh/year and require an in-house procurement function with risk appetite. Pass-through contracts sit between the two and are useful when non-commodity costs are expected to fall.

Business energy questions, answered
How much can I save on business energy?
Most UK businesses we quote save between 15% and 45% versus their existing rate, particularly if they're currently on out-of-contract or deemed-rate tariffs. Savings depend on your usage profile, meter type, and where wholesale prices sit when you switch — we'll show you the realistic number with your actual usage data, not a marketing headline.
How long does it take to switch business energy supplier?
The quote itself takes 60 seconds. The full switch typically completes in 2 – 6 weeks (4 weeks is most common) with zero interruption to your gas or electricity supply. The new supplier handles meter reads and the technical handover — you don't need to do anything other than approve the contract.
What if I'm tied into a current contract?
You can still get quoted now and lock in tomorrow's rates today. Most business energy contracts allow you to sign a forward contract up to 12 months before your current one ends — meaning you secure today's prices without affecting your current supply. We'll diary your contract end date and trigger the switch automatically when it expires.
How are you paid if the service is free?
We're paid a small commission by the winning supplier — never by you. Crucially, our commission is similar across most suppliers, so we have no incentive to push one over another. We always recommend on rate, contract terms and supplier reputation, not commission. We'll happily disclose our commission on any contract you sign.
Do you offer green / renewable energy tariffs?
Yes — REGO-backed (Renewable Energy Guarantees of Origin) tariffs are available from suppliers including Octopus Energy, Good Energy and SmartestEnergy. We can quote a fully renewable contract or a mixed-source contract depending on your sustainability commitments and budget.
Can you handle multi-site portfolios?
Yes. Whether you have 2 sites or 200, we'll structure the contract however suits you — single supplier across all sites for simplicity, or supplier-of-choice per site for sharpest pricing. One account manager handles the entire portfolio and consolidated invoicing where supported.
What are the best business electricity prices in the UK right now?
For most UK SMEs in 2026 the best business electricity prices sit between 22 p and 28 p per kWh on a 24-month fix, with a daily standing charge of 35 p – 65 p. Larger sites (50,000+ kWh / year) typically secure 18 p – 24 p per kWh. The cheapest unit rate isn't always the best deal — standing charges, exit fees and contract terms all affect your true annual cost. Get a live quote and we'll show you the genuine best business electricity prices available for your meter and postcode today.
How do I find the best business electricity rates UK suppliers are offering?
Suppliers reserve their best business electricity rates for brokers and aggregators rather than publishing them on the open market — and which supplier is cheapest changes weekly depending on wholesale prices and DNO region. We compare 23+ UK business electricity suppliers on live rates each day, including British Gas Business, EDF Business, Octopus Energy, SmartestEnergy, SSE, E.ON Next Business and Total Energies. You'll see the top 3 with full annual cost, contract terms and our honest recommendation in 60 seconds.
What's the best business electricity tariff for a small business?
For most UK small businesses, a 24-month fixed-rate business electricity tariff is the best fit — it gives 2 years of price certainty, lets you budget accurately, and is long enough to ride out short-term wholesale spikes. 12-month fixes work well if you expect wholesale prices to fall sharply; 36-month fixes suit businesses with stable usage who want maximum certainty. Pass-through and flexible tariffs are usually only worthwhile above 250,000 kWh / year.
How are business electricity prices different from domestic prices?
Business electricity is taxed at 20% VAT (vs 5% domestic) and isn't covered by the Ofgem domestic price cap, so prices are negotiated commercially. The upside: business electricity unit rates are typically 30 – 50% lower than domestic per-kWh rates because suppliers negotiate bespoke contracts. The downside: there's no cap and no automatic cooling-off period — once you sign, you're contractually committed for the term, which is why getting the best business electricity rates UK-wide on day one matters.
When is the best time to switch business electricity supplier?
The best time to switch is 6 to 12 months before your current contract ends. UK business electricity suppliers let you sign forward contracts and lock in today's rates without affecting your current supply. If wholesale prices drop in that window you've already secured the saving; if they rise you've protected yourself from the increase. We'll diary your renewal window and trigger the retender automatically — you never accidentally roll onto out-of-contract rates.
Are the best business electricity prices always from the cheapest supplier?
No. The cheapest headline unit rate often comes with a higher daily standing charge, stricter exit fees, weaker payment terms, or poor service ratings. We rank suppliers on total annual cost using your real consumption data, then weight by contract terms and service reputation. Sometimes the supplier with the second-cheapest unit rate is the genuine best business electricity deal once everything's factored in — and we'll always tell you why.
Can I get the best business electricity tariff if I'm out of contract?
Yes — and you should switch immediately. Out-of-contract and deemed-rate business electricity tariffs are typically 35 – 50% more expensive than the best fixed rates. There's no exit fee on a deemed tariff and the new supplier handles the entire switch in 2 – 6 weeks with no interruption to supply. If you've been on a deemed tariff for over a month, you're losing money every single day until you switch.
