Energy saving tips for restaurants start with practical changes that cut costs fast: upgrade to Energy Star-rated kitchen equipment, switch traditional light bulbs to energy efficient lighting such as LEDs, which use 75-80% less energy than traditional bulbs and can reduce costs by up to 90%, maintain appliances, optimise refrigeration, install programmable thermostats, improve cooking and ventilation habits, insulate hot water systems, fit low-flow taps, and use energy management systems to measure how much energy your site is using. Commercial kitchens use up to 10 times more energy than offices and 5–7 times more energy per square foot than typical commercial spaces, which underlines the importance of getting efficiency basics right.
For UK restaurant owners, operators and hospitality managers running commercial kitchens, bars or multi-site venues, where most sites use between 50,000 and 90,000 kWh annually, these strategies help reduce energy costs and carbon emissions without disrupting service. You’ll see where restaurants are commonly wasting energy, how to conduct an energy audit, when to use smart meters, time switches, movement detectors or daylight sensors, and what to maintain regularly, from air conditioning, with automatic door closers helping reduce drafts and heating/cooling demand, and lighting to refrigeration units you should regularly defrost to better monitor energy use.
The focus is on practical, sustainable ways to save money in the short term and the long run, with clear advice on using less energy for cooking, food storage, water heating and front-of-house systems, including grouping cooking tasks to save energy by improving thermal efficiency during food preparation. Where a business needs more than quick fixes, Powerhub Solutions also provides turnkey energy-saving technology and support to help measure results with real data and deliver responsible, measurable savings.
- 1
Upgrade to Energy-Efficient Appliances – Invest in Energy Star-rated equipment to significantly cut down your energy use.
- 2
Use LED Lighting
Switching to LED lighting can reduce energy consumption by up to 75%. - 3
Regular Maintenance
Regularly servicing your appliances keeps them running efficiently, saving energy and extending their lifespan. - 4
Optimise Refrigeration Units
Ensure your refrigeration units are working efficiently by regularly checking seals and cleaning condenser coils. - 5
Install Programmable Thermostats
Programmable thermostats help regulate temperatures during off-peak hours, saving on heating and cooling costs. - 6
Energy-Efficient Cooking
Using energy-efficient cooking techniques, such as turning off burners when not in use, can reduce unnecessary energy waste. - 7
Utilise Natural Ventilation
Use natural ventilation instead of mechanical cooling whenever possible to save energy. - 8
Insulate Water Heaters and Pipes
Insulating your water heaters and pipes reduces heat loss, saving energy in water heating. - 9
Install Low-Flow Faucets
Low-flow faucets reduce water usage, cutting down on both water and energy bills. - 10
Implement an Energy Management System
An energy management system allows you to monitor and optimise energy usage in real-time.
How Powerhub Solutions Can Help with Energy Efficiency
At Powerhub, we offer a range of commercial energy-saving solutions specifically designed for commercial kitchens, bars, and restaurants to help further reduce energy consumption:
Each solution integrates seamlessly into your operations, offering immediate savings and a quick return on investment, especially when deployed alongside KBR Energy Saver refrigeration optimisation across walk-in fridges, cellars, and bar coolers. Smart meters can also lead to more accurate billing for restaurants while helping track energy use, and specialist energy saving for restaurants and pubs can turn these insights into sustained reductions in consumption.
With tailored solutions, site surveys, and ongoing support, our KBR solutions can help you create a more energy-efficient and cost-effective business. We can also provide advice on strategies and practical ideas, using the right technology to show operators how much energy they use and where too much energy is being lost. For example, smart controls and smart meters provide clear data, helping you conduct an energy audit, identify waste, and find more ways to save money. This can cut energy costs in the long run, support a more sustainable operation, and reduce impact on the environment as part of a sustainable future, as illustrated by large-scale hospitality case studies like Whitbread. Smart thermostat settings for heating and air conditioning can also help; turning temperatures down by 1°C saves energy, and teams often realise the gains quickly. Training staff is equally important, so assign a responsible person to lead targets and encourage habits that benefit both the business and customers. If you want to switch to a more efficient setup, it can make sense to invest in upgrades, and businesses can also invest in induction hobs because they convert 85% of energy into heat for cooking. Energy efficient appliances such as dishwashers can save an average of £1,500 annually.
These measures can save money while improving day-to-day performance, and we hope they help operators adopt lasting changes.
