Save Energy on Your Fridge, Freezer and Dishwasher with Proper Use
Save Energy on Your Fridge, Freezer and Dishwasher with Proper Use
Your fridge, freezer and dishwasher are among the biggest energy users in your home. They run for many hours every day and are essential for modern living – but with a few simple changes in how you use and maintain them, you can cut both your electricity bills and your carbon footprint. Here’s a practical guide to getting the most out of your appliances without sacrificing convenience.
The Fridge – Small Adjustments, Big Savings
Because your fridge runs 24/7, even small improvements can make a noticeable difference to energy use.
- Set the right temperature. Around 5°C is ideal for most fridges. Every degree colder can increase energy consumption by up to 5%.
- Close the door quickly. Each time the door is open, cold air escapes and the compressor has to work harder to cool down again.
- Allow space for ventilation. Make sure there’s a gap behind and around the fridge so heat can escape efficiently.
- Defrost and clean regularly. Dust on the coils or ice build-up inside makes the fridge work harder. A quick clean a couple of times a year helps it run efficiently.
- Keep it reasonably full. A well-stocked fridge maintains its temperature better. If it’s half empty, fill bottles with water to help stabilise the temperature.
The Freezer – Keep It Cold, Not Frosty
Freezers use even more energy than fridges, especially if they’re old or poorly maintained.
- Set the temperature to -18°C. That’s cold enough to keep food safe without wasting energy.
- Defrost when needed. Just 5 mm of ice can increase energy use by up to 30%.
- Keep it full. A full freezer retains cold better. If you don’t have much food, fill empty spaces with bags of ice or containers of water.
- Place it in a cool spot. Avoid putting the freezer near radiators, ovens or direct sunlight.
- Check the door seals. If the door doesn’t close tightly, cold air escapes and energy use rises.

The Dishwasher – Clean Dishes, Lower Bills
Used wisely, a dishwasher can actually be more efficient than washing up by hand.
- Run full loads. A half-empty dishwasher uses almost as much energy as a full one.
- Choose the eco or energy-saving programme. It takes longer but uses less electricity and water because the water is heated more gradually.
- Skip the pre-rinse. Modern dishwashers can handle dirty dishes without rinsing first – just scrape off food scraps.
- Run it at off-peak times. If you’re on a time-of-use electricity tariff, running the dishwasher overnight can save money.
- Clean the filter regularly. A clean filter helps water circulate properly and keeps the machine running efficiently.
Maintenance and Replacement – Think Long Term
Even the best habits can’t make up for an old, inefficient appliance. If your fridge, freezer or dishwasher is more than 10–15 years old, it might be worth replacing.
- Check the energy label. Appliances rated A or better use significantly less electricity than older models.
- Choose the right size. Larger appliances use more energy, even when not full.
- Recycle responsibly. Old appliances contain refrigerants and materials that must be disposed of safely. Contact your local council or recycling centre for proper collection.
Small Habits, Big Impact
Saving energy isn’t just about technology – it’s about everyday habits. Close doors quickly, use eco programmes, and keep your appliances clean. These small actions don’t take much effort, but over time they can make a real difference to your energy bills and the environment.
By using your fridge, freezer and dishwasher wisely, you’ll not only reduce your energy consumption but also extend their lifespan and contribute to a more sustainable home.
