A Data-Backed Guide to Business Energy Savings (July 2026)
- 2 days ago
- 5 min read
UK SMEs typically overpay on business energy bills by £1,500 to £3,000 per year depending on usage. The main reason? Staying on expired contracts where suppliers quietly charge you more. Businesses that compare and switch could expect savings of around 15 to 30% depending on their current deal.
What You're Probably Paying Right Now
If you haven't switched or renegotiated your energy contract recently, here's what July 2026 looks like, all dependent on usage of course:
On a fixed deal (actively managed): 23–30p per kWh for electricity, depending on your usage and supplier. The average UK SME pays around 27.8p/kWh (Source: EU Energy Live, 19 July 2026). Average annual bill: £5,192 across all business sizes (Source: POWWR Barometer, 670,000 businesses surveyed, June 2026).
On an expired contract (out-of-contract/deemed rate): The average across 15 major suppliers is 35.63p/kWh, with some charging up to 47.50p/kWh (Source: Purely Energy, "UK Business Out-of-Contract Rates 2026"). Specific examples: EDF charges 34.64p, United Gas & Power charges 40.8p.
What does that mean in plain English?
If your contract has expired and you haven't done anything, you're paying roughly 30 to 50% more than a business that shopped around. On 15,000 kWh of energy usage (typical micro-business), that's £1,200 to £1,500 per year wasted. On 40,000 kWh of energy usage (typical small business), it's £3,200 to £4,000.
How do you know if you're on a deemed rate?
Check your bill for "deemed," "out of contract," or "variable" pricing. If your contract end date has passed and you didn't sign a new one, you're on it.
The Market Right Now (July 2026) and Why Timing Matters
Energy prices aren't fixed. They move based on global events, just like petrol. Here's what's currently happening:
Electricity wholesale costs (what suppliers pay before adding their margin) are at £94 to £116/MWh in July 2026. That's up from about £75/MWh earlier in the year, but still well below the crisis peak of £300+/MWh back in 2022.
Gas wholesale costs have spiked to around 140p/therm (roughly double what they were in January 2026) because of military conflict between the US and Iran disrupting shipping routes that carry gas to Europe.
What this means for you:
Prices are rising, not falling. If your contract is expiring in the next 6 months, waiting will likely cost you more. But even at today's rates, switching from a deemed rate to a fixed deal saves you significantly.
Some very Important context: UK business electricity prices are 92% higher than the European average for medium-sized businesses (Source: Ofgem, January 2026).
We're paying nearly double what competitors in Europe pay. Active management of your energy costs isn't optional, it should be mandatory.
What You Should Be Paying with Benchmarks by Business Size
If you're above these ranges, you're likely overpaying.
Your Business Size | Electricity (Annual) | Gas (Annual) | Total Energy | You Could Save |
Sole trader / 1 person | £1,200–£1,800 | £600–£900 | £1,800–£2,700 | £400–£800 |
Micro (2–9 staff) | £2,100–£3,400 | £1,100–£1,900 | £3,200–£5,300 | £800–£1,600 |
Small (10–49 staff) | £5,400–£9,200 | £2,800–£4,600 | £8,200–£13,800 | £1,500–£3,000 |
Medium (50–249 staff) | £12,000–£24,000 | £6,000–£12,000 | £18,000–£36,000 | £3,000–£7,000 |
Note: These ranges reflect contracts negotiated in 2026. If you're on a deal signed during the 2022–2023 crisis at 50–60p/kWh, your saving on renewal could be much larger.

Top 5 Business Energy Suppliers (July 2026)
Based on our comparison of 47 suppliers and all of our switches managed this year, the rates change frequently, so these are rankings by overall value, not just fixed prices.
1. Corona Energy — Best for small/micro-businesses.
2. British Gas Business — Best for medium businesses wanting a dedicated account manager. Free smart meter installation.
3. EDF Business — Best for businesses needing green credentials for reporting. 100% renewable backed by certificates. Costs virtually the same as standard tariffs now.
4. E.ON Next Business — Best for multi-site businesses. Fully digital sign-up and management.
5. Scottish Power Business — Best for small businesses using 20,000–50,000 kWh. Competitive for that mid-range.
Why "green" tariffs aren't more expensive anymore: The certificates suppliers use to prove renewable energy (called REGOs) crashed in price to just £0.30 per MWh, down from £15 in 2023. Green tariffs now cost 0–0.5p/kWh more than standard. For most businesses, that's under £50/year extra (Source: Good Energy, January 2026).
Why You Won't Find These Rates by Calling Suppliers Directly
In our 2026 data across all our managed switches:
Businesses that went through us got rates 8–12% below the price the same supplier quoted them online
The gap between the cheapest and most expensive quote for identical usage averaged 26%
Around 70% of businesses we reviewed weren't on the cheapest tariff available from their own current supplier
This isn't unusual. Ofgem's latest research (May 2026) found only 29% of businesses switched supplier in the past year. The rest either didn't know they could, didn't think it was worth it, or assumed it was too complicated.
In reality: 78% of businesses who switched rated the process as easy (Ofgem, 2025).

The Bigger Picture and Why This Matters Now
27% of UK businesses are currently struggling to pay energy bills (British Chambers of Commerce, February 2026, survey of 600+ firms)
65% of businesses rank energy prices as their single biggest risk, ahead of cybersecurity, staffing, and cash flow (CBI/Energy UK, 2026)
UK business energy bills rose 9.3% in Q1 2026 alone (POWWR, June 2026)
Rates are still 70–75% above pre-2021 levels despite falling from the 2023 peak
This isn't going back to "normal." The businesses that actively manage their energy procurement will have a cost advantage over those that don't.
Your Switching Checklist
How long does it take? 5 working days for standard meters (Source: Ofgem guidance). No interruption to your supply. Nothing gets turned off.
What do you need, and what we will ask for?
Your MPAN number (electricity) or MPRN (gas) on your bill
Your annual usage in kWh, simply check your last 12 months of bills
