If you run a restaurant, takeaway or cafe in the UK, your restaurant's energy bill has stopped being a background cost and become a line you watch like the wages. And in 2026, the worst of it isn't even the unit rate — it's a quieter change to your standing charge that lands whether you cook one cover or two hundred.
This guide walks through it the way you'd actually tackle it on a slow Tuesday: understand what changed, read your bill properly, fix the tariff, then cut the load. Energy is one of the few big overheads you can still pull on — but only if you treat it as a job, not a thing to dread.
Key takeaways
- Standing charges are the 2026 story, not just unit rates. Business electricity standing charges were set to "increase by almost double in April 2026" as network costs are reallocated (MoneySuperMarket, 2025).
- The change hits multi-meter sites hardest. TNUoS demand-residual revenue is "projected to rise from £3.84bn in 2025/26 to £7.52bn in 2026/27", recovered as flat charges "applied per site, per day" (UKHospitality, 2026).
- A mid-sized restaurant now burns £1,800 to £3,500 a month on energy alone (AFC Stuff, 2026), and refrigeration is usually the single biggest line.
- The most expensive mistake is sitting on the variable rate. Owners "pay the rolling variable rate instead of fixing for 12 or 24 months when the market dips" (AFC Stuff, 2026).
- Efficiency still pays even when prices rise. UK hospitality businesses "could reduce their energy consumption by 10 to 14 percent" through Carbon Trust-style measures, with cleaned extraction and LED lighting among the quickest wins (Yu Energy, 2025).
What actually changed in 2026, and why your bill jumped
The short answer: a chunk of the cost of running the electricity grid is being moved onto standing charges — the fixed daily fee you pay before you've used a single kilowatt-hour.
The mechanism is a charge called TNUoS (Transmission Network Use of System). For 2026/27, the demand-residual portion of it is "projected to rise from £3.84bn in 2025/26 to £7.52bn in 2026/27", and because these are "flat charges applied per site, per day, multi-site operators – hotels, restaurant groups and food retailers – will be among the hardest hit" (UKHospitality, 2026). In plain terms: every meter you have now carries a bigger daily fee, every day of the year, busy or dead.
That's why MoneySuperMarket reported electricity standing charges for businesses were planned to "increase by almost double in April 2026", with the underlying TNUoS charges rising "by £3.7billion... a change of around 94%" (MoneySuperMarket, 2025). For a half-hourly metered site, standing charges already sit in the region of "£8-£20/day" — roughly £2,920–£7,300 a year before any usage (Meet George, 2025).
There's a second overhead moving at the same time: business rates. From 1 April 2026 the temporary 40% retail, hospitality and leisure relief ends, replaced by permanently lower multipliers — a small-business RHL multiplier of 38.2p and a standard RHL multiplier of 43p for properties under £500,000 of rateable value (Cambridge City Council, 2026). Whether that's better or worse than last year depends entirely on your rateable value after the revaluation, which is why it pays to check your bill rather than assume. Total business-rates receipts are forecast "to rise by £3.4bn to £37.1bn in 2026/27" as the revaluation takes effect (Morning Advertiser, 2026). For the wider squeeze on margins, our guide to UK restaurant wage costs in 2026 covers the other big fixed-cost rise landing this year.
Step 1: Read your bill like an operator, not a bill-payer
Before you can cut anything, you need to know what you're actually paying for. A business energy bill has three moving parts, and owners routinely only look at one of them.
- Unit rate (p/kWh) — what you pay for each unit of energy used. This is the part that scales with how busy you are.
- Standing charge (p/day) — the fixed daily fee per meter, regardless of usage. This is the part that jumped in 2026.
- Pass-through and non-commodity costs — network charges (including TNUoS), levies and VAT, sometimes bundled into the unit rate, sometimes itemised.
Pull your last 12 months of bills and write down, for each meter: the unit rate, the standing charge, your contract end date, and whether you're in or out of contract. The single most useful number is your annual consumption in kWh — it's on the bill, and every broker and supplier will ask for it. If you've drifted out of contract, you'll likely be on "deemed" or variable rates, which are almost always the most expensive tariff a supplier offers.
Step 2: Fix the tariff before you touch a fridge seal
The biggest lever on most restaurant energy bills isn't a gadget — it's the contract. The common, costly mistake is inertia: owners "underestimate energy and pay the rolling variable rate instead of fixing for 12 or 24 months when the market dips" (AFC Stuff, 2026). On a variable rate you carry all the risk; on a fix you buy certainty, which is worth a lot when you're trying to set menu prices six months out.
Here's how to approach it without getting talked into something:
- Know your end date. Most business contracts have a narrow renewal window; miss it and you roll onto expensive out-of-contract rates. Diarise it 90 days out.
- Get your annual kWh and meter numbers ready — fixing a quote needs both.
- Compare at least three quotes on a like-for-like basis: same contract length, same standing charge assumptions, unit rate quoted ex-VAT.
- Decide fix vs variable deliberately. A fixed tariff locked on a market dip protects you from the next spike; given the standing-charge changes, certainty has rarely been worth more.
- Watch the standing charge, not just the unit rate. A headline-cheap unit rate with a fat daily standing charge can cost a low-volume cafe more than the reverse.
One honest caveat: efficiency alone won't save you here. As Flipdish put it, "reducing consumption does not fully protect you, because the bill rises even when you run lean" — the fixed charges climb regardless (Flipdish, 2026). That's exactly why the tariff comes first and the load second.
Step 3: Cut the load — refrigeration, extraction and lighting
Once the tariff is sorted, attack the usage. The good news is that hospitality has plenty of slack: UK hospitality businesses "could reduce their energy consumption by 10 to 14 percent", and "even a few simple measures can achieve a 10 percent reduction" (Yu Energy, 2025). Start where the energy actually goes.
Refrigeration first — it never switches off. Walk-in fridges, freezers and prep units "run 24 hours a day and never switch off, which is why refrigeration is usually the single biggest line on the electricity bill" (AFC Stuff, 2026); studies put refrigeration at up to 50% of a restaurant's total electricity use (Restaurant Management, 2024). The fixes are unglamorous and cheap: replace perished door seals, keep condenser coils clean and dust-free, leave airflow gaps around the back, defrost on schedule, and stop cramming hot stock into the walk-in. Every degree the unit has to fight for costs money.
Extraction is the second-biggest hidden draw. A canopy running flat-out all service moves enormous volumes of conditioned air. A "regularly cleaned ventilation system can be up to 25 percent more efficient", and where controls allow, ramping fan speed to match the cooking load rather than running full-tilt all day is a straightforward win (Yu Energy, 2025).
Lighting is the easy one. Switching to LED and adding occupancy sensors in stores, toilets and offices is low-effort: hotels and restaurants "have been able to reduce their lighting costs by as much as 50 percent", with sensors driving "30-50 percent" savings on the spaces they cover (Yu Energy, 2025).
Here's where the load-side wins sit, roughly in order of effort:
| Measure | Effort | Typical saving |
|---|---|---|
| Replace fridge seals, clean condensers, schedule defrosts | Low | Targets refrigeration — up to 50% of total electricity use |
| Clean and right-size kitchen extraction | Low–medium | Ventilation "up to 25 percent more efficient" |
| LED lighting + occupancy sensors | Low | Lighting costs down "as much as 50 percent" (sensors 30–50%) |
| Closedown checklist + behaviour changes | Low | "A few simple measures" ≈ 10% off consumption |
| Full efficiency programme | Medium | 10–14% off total consumption |

Step 4: Win on behaviour and maintenance
Kit gets the headlines, but habits move the meter day to day. None of these cost anything beyond a bit of rota discipline.
- Stagger your start-up. Don't fire up every oven, grill and fryer at once first thing — bring equipment up to temperature in sequence, close to service, not at 8am for a 12pm open.
- Shut down properly. A simple end-of-night switch-off checklist (extraction down, non-essential fridges and display units off, standby kit killed at the wall) stops overnight phantom load.
- Prep to the menu. Batch oven use, fill the oven when it's on, and lid your pans — uncovered pots waste a startling amount of gas and electricity.
- Maintain on a schedule. Service your refrigeration and extraction before they fail, not after; a struggling compressor burns money for weeks before it dies.
- Make it someone's job. Energy that's nobody's responsibility creeps up. Give a shift lead the closedown checklist and check the meter reading weekly.
These are the "simple measures" that reliably land that first ~10% — and unlike the standing charge, they're entirely within your control.
Step 5: Get help — brokers, the grid and relief
When you've done the basics, it's worth bringing in specialists for the parts that need leverage or paperwork.
- A reputable energy broker can run the market for you at renewal and is paid by the supplier — but always ask how they're remunerated and get the underlying rates in writing, not just a "saving" figure.
- Half-hourly (HH) and capacity charges reward shifting load off peak where you can; if you have an HH meter, ask your supplier or broker to explain your specific capacity charge and whether your agreed capacity (kVA) is set too high.
- Check your business rates relief. With the 2026 revaluation and the new RHL multipliers, your rateable value may have changed; if it looks wrong, you can challenge it, and pubs and certain venues receive extra support in 2026/27 (Cambridge City Council, 2026).
- Look at on-site generation only after the cheap wins — solar with a battery can shave peak draw, but the payback maths only works once you've stopped wasting energy first.
Energy is a fixed cost you can actually negotiate down — unlike the commission on a delivery order. Owners already losing 14–30% of every aggregator sale (see our breakdown of Deliveroo, Just Eat and Uber Eats commissions) feel the energy squeeze twice as hard, because both are eating the same thin margin. Every pound you claw back on the standing charge is a pound you keep. And the more of your trade you can route through channels you own — your own direct ordering page rather than a commission-charging app — the more of each sale survives to cover bills like this one. A tool such as DineHere can stand a simple ordering site up quickly, but the principle holds whoever builds it: own the order, keep the margin.
A fixed tariff locked on a market dip can save more than a month's delivery commission — and unlike the apps, the saving lands every single day, busy or quiet.
Frequently asked questions
Why has my restaurant's standing charge gone up so much in 2026?
Network costs are being reallocated onto fixed daily charges. Business electricity standing charges were set to "increase by almost double in April 2026", driven by TNUoS charges rising around 94% (MoneySuperMarket, 2025). Because the charge is per meter per day, it lands regardless of how busy you are.
How much does a UK restaurant spend on energy each month?
It varies with size and equipment, but "a mid-sized restaurant burns through £1,800 to £3,500 a month on energy alone" (AFC Stuff, 2026). Refrigeration, cooking and extraction make up the bulk of it.
Should I fix my energy contract or stay on a variable rate?
A fixed contract gives you price certainty, which matters when you're setting menu prices months ahead. The common mistake is paying "the rolling variable rate instead of fixing for 12 or 24 months when the market dips" (AFC Stuff, 2026). Compare at least three like-for-like quotes before deciding.
What uses the most electricity in a commercial kitchen?
Refrigeration is usually top because it runs around the clock — up to 50% of a restaurant's electricity use by some studies (Restaurant Management, 2024) — followed by cooking equipment and extraction. That's why fridge seals, clean condensers and well-managed extraction give the best return.
Can energy efficiency actually offset the price rises?
Partly. UK hospitality businesses "could reduce their energy consumption by 10 to 14 percent" (Yu Energy, 2025). But "reducing consumption does not fully protect you, because the bill rises even when you run lean" (Flipdish, 2026) — the fixed charges climb regardless, which is why fixing the tariff matters too.
What's the quickest energy win in a restaurant?
Cleaning and maintenance. A "regularly cleaned ventilation system can be up to 25 percent more efficient", and LED lighting can cut lighting costs "by as much as 50 percent" (Yu Energy, 2025). Both are low-cost and fast to do.
How do I read a business energy bill?
Look for three things: the unit rate (p/kWh, scales with usage), the standing charge (p/day, fixed per meter), and your annual consumption in kWh. Note your contract end date too — drifting out of contract usually means expensive variable rates.
Are business rates going up for restaurants in 2026?
The temporary 40% RHL relief ends on 1 April 2026, replaced by permanently lower multipliers — 38.2p for small businesses and 43p standard for properties under £500,000 rateable value (Cambridge City Council, 2026). Whether your bill rises or falls depends on your new rateable value after the revaluation.
Is it worth using an energy broker?
It can be, especially at renewal when you don't have time to run the market yourself. Brokers are paid by suppliers, so ask exactly how they're remunerated and insist on seeing the underlying unit and standing rates in writing, not just a headline "saving".
Should I look at solar panels for my restaurant?
Consider it after the cheaper wins. Solar — ideally with a battery — can reduce peak-time grid draw, but the payback only stacks up once you've fixed your tariff and stopped wasting energy on poor refrigeration and lighting. Do the basics first.
