How Much Should a UK Restaurant Spend on Energy?
Key Takeaway: UK restaurant energy benchmark is 3-5% of net revenue. A restaurant doing £10,000/week should spend £300-500/week on gas and electricity. Post-2022, many operators are running at 6-8% — a direct hit to GP%. This guide gives you the benchmarks, the biggest cost drivers, and the fastest wins.

UK Restaurant Energy Cost Benchmarks 2026
| Restaurant type | Energy % of revenue | Weekly cost (£10,000/week) |
|---|---|---|
| Café / light kitchen | 2-3% | £200-300 |
| Casual dining / pub food | 3-5% | £300-500 |
| Full-service restaurant | 4-6% | £400-600 |
| High-volume kitchen (takeaway-heavy) | 5-8% | £500-800 |
Biggest Energy Cost Drivers in a Restaurant Kitchen
| Equipment | Typical daily cost (continuous) | Reduction opportunity |
|---|---|---|
| Commercial oven (6-burner range) | £8-15 | Turn off between services |
| Extraction system | £4-8 | Run only during cooking |
| Dishwasher (commercial) | £5-12 | Batch — never run half-loaded |
| Walk-in fridge (older unit) | £4-6 | Check door seals and coils |
| Fryers (3 × commercial) | £10-20 | Switch off between services |
| Hot holding units | £2-4 | Turn off if not in use |
Quickest Energy Wins for Independent Restaurants
Switch off idle equipment between services. A fryer idling at temperature costs £3-5/day — £1,000-1,800/year — for zero output. A written equipment on/off schedule saves money immediately with zero capital investment.
Check fridge and freezer door seals. A worn seal causes the compressor to run 20-30% harder — a HACCP risk as well as a cost issue. Seal replacement costs £30-80 per door.
Review your energy contract. Most independent restaurants are on out-of-contract rates (30-50% above contract rates) because the original deal expired. A commercial energy broker can source a fixed-rate contract significantly below default variable rate.
LED lighting throughout. A full LED retrofit for a 60-cover restaurant typically costs £500-1,500 and pays back within 6-18 months.
Energy should appear as a fixed cost line in your weekly P&L. See the restaurant weekly P&L guide for how to structure cost lines. The Restaurant Console Energy Tracker calculates kitchen and FOH energy cost as a percentage of revenue automatically.

How can I reduce energy costs in my restaurant?
Turn off cooking equipment between services, check fridge/freezer door seals, switch to a fixed energy contract, install LED lighting, run dishwasher only when fully loaded. Typically saves 15-25%.
Should restaurant energy costs be tracked weekly or monthly?
Weekly. Divide your monthly bill by 4 and include it as a weekly P&L line to spot trends early.
How do I calculate energy cost as a percentage of restaurant revenue?
Energy cost% = Total energy spend ÷ Net revenue × 100. Example: £400/week ÷ £10,000 = 4%.
