How Rising Energy Costs Affect Curry Restaurants

The Bill That's Eating Your Profits

In January 2022, the average monthly energy bill for a mid-sized curry restaurant in the UK sat around £1,200 to £1,800. By the winter of 2022-23, that same restaurant was staring at invoices of £4,000 to £6,000 — in some cases more. Energy prices have retreated somewhat since their peak, but as of early 2026, they remain roughly double what they were before the crisis began. For an industry that operates on thin margins at the best of times, this sustained cost increase has been devastating. UKHospitality reported that energy bills are now the second-largest overhead for restaurants after staff costs, overtaking rent in many cases.

Curry restaurants are hit harder than most. A tandoor oven blazing at 480°C for twelve hours. Multiple gas burners running simultaneously during service. Commercial ventilation extracting heat and fumes continuously. Walk-in fridges and freezers humming round the clock. The energy intensity of a curry kitchen is genuinely remarkable — and every kilowatt hour costs roughly three times what it did four years ago.

Understanding Where the Energy Goes

Before you can cut costs, you need to understand where the energy is actually being consumed. A typical curry restaurant's energy breakdown looks something like this:

• Cooking equipment (45-55%) — The tandoor alone can account for 15-20% of your total energy bill. Gas burners, griddles, fryers, and ovens make up the rest. This is your largest single area of consumption.
• Ventilation and extraction (15-20%) — Commercial kitchen extraction systems are energy-hungry by design. They need to move enormous volumes of air to maintain safe working conditions and comply with building regulations.
• Refrigeration (10-15%) — Walk-in fridges, freezers, prep fridges, display units. These run continuously and are sensitive to ambient temperature — a hot kitchen makes them work harder.
• Lighting (5-10%) — Often overlooked, but in a restaurant open fourteen hours a day, lighting costs accumulate rapidly.
• Hot water and miscellaneous (5-10%) — Dishwashers, hand basins, cleaning, heating the dining area.

The Tandoor: Your Biggest Energy Decision

A traditional clay tandoor running on gas or charcoal is a magnificent cooking tool — and an extraordinarily inefficient one from an energy perspective. It takes 45-60 minutes to reach operating temperature, it runs at extreme heat all through service, and most of that heat escapes rather than transferring to the food. Some estimates suggest a traditional tandoor converts only 20-30% of its energy input into actual cooking.

Modern electric and gas tandoor ovens with improved insulation, heat recovery systems, and programmable controls offer significantly better energy efficiency. They reach temperature faster, maintain it more consistently, and waste less heat. The capital cost of upgrading (£3,000-8,000 for a quality commercial tandoor) is significant, but the energy savings can be £200-400 per month, delivering payback within one to three years depending on your usage.

"We switched to an insulated gas tandoor with a thermostat last year. Our gas bill dropped by £180 a month. But honestly, the biggest surprise was the consistency — the naans and tikka come out better because the temperature doesn't fluctuate like it did with the old clay one." — Restaurant owner, Sparkhill, Birmingham

Quick Wins: Changes You Can Make This Week

LED Lighting

If you haven't already switched to LED throughout your restaurant, do it today. A typical curry restaurant with traditional halogen or fluorescent lighting spends £60-120 per month on lighting alone. LEDs cut this by 60-80%. The bulbs cost more upfront (£3-8 each versus £1-2 for halogens) but last ten times longer and pay for themselves within three to six months. This is the single easiest energy saving available.

Smart Meters and Real-Time Monitoring

You can't manage what you can't measure. A smart meter gives you real-time visibility into your energy consumption. Better still, energy monitoring systems like those from Hark, Clever Energy, or even simple plug-in monitors on individual appliances show you exactly which equipment is costing what. Many restaurant owners are shocked to discover that a single piece of equipment — often an older fridge or a faulty extraction fan — is responsible for a disproportionate share of their bill.

Cooking Schedules and Equipment Management

Do you fire up every burner at 10am even though service doesn't start until 5pm? Do the extraction fans run at full speed all day regardless of cooking intensity? Is the tandoor lit at opening and left burning until close, even during the quiet three-hour gap between lunch and dinner? These habits developed when energy was cheap and nobody questioned them. Now, every wasted hour of operation costs real money.

Implement a structured equipment schedule: tandoor fired 90 minutes before service, extraction fans on variable speed (adjusting to cooking intensity), burners lit in sequence as prep requires them, lights dimmed during non-trading hours. Small disciplines that compound into significant savings.

Equipment Upgrades That Pay for Themselves

Induction Hobs

Induction cooking is 85-90% energy efficient compared to 40-55% for gas. For curry restaurants, induction is ideal for sauce preparation, dal cooking, and any task that doesn't require a naked flame. The initial cost is higher (£500-2,000 per unit), but the running cost is substantially lower. Many restaurants are adopting a hybrid approach: gas for high-heat wok-style cooking and tandoor work, induction for everything else.

High-Efficiency Dishwashers

Modern commercial dishwashers use significantly less water and energy than models from even five years ago. If your dishwasher is more than seven years old, replacing it could cut water and energy consumption for that function by 30-40%. Look for models with heat recovery systems that capture waste heat from the drain water and use it to pre-warm incoming water.

Refrigeration Upgrades

Older commercial fridges and freezers can be extraordinarily energy-hungry. Modern units with improved compressors, better insulation, and automatic defrost cycles use 40-50% less energy. If your walk-in fridge dates from the early 2010s or before, a replacement will likely pay for itself within two to three years through energy savings alone.

Government Support and Grants

Several government and local authority schemes exist to help small businesses reduce energy costs. The Energy Technology List (ETL) provides tax benefits for purchasing qualifying energy-efficient equipment. Some local councils offer grants for small business energy audits and improvements — check your council's business support page. The British Business Bank's Start Up Loans programme can fund energy-efficiency investments alongside other business costs.

British Gas, EDF, and other energy suppliers also offer business energy audits, sometimes free of charge, that identify the most impactful improvements for your specific premises. It's worth requesting one even if you don't intend to switch supplier — the audit findings are yours to keep.

Renegotiating Your Energy Contract

If you've been on a variable tariff, you may be paying significantly more than necessary. Fixed-rate business energy contracts offer price certainty and are often cheaper than variable rates in the current market. Use comparison sites like Bionic, Make It Cheaper, or Utility Bidder to check whether a better deal is available. Lock in a competitive rate when you find one — energy markets remain volatile and prices can shift quickly.
