With energy prices still high, there are limited options for both saving money and limiting your impact on the environment. Previously you’d have been able to switch to a better energy deal with one of the increasing number of green energy suppliers, but this is no longer the case.

However, there are still some practical things you can do at home to use less energy, help the environment and save money on your bills while you wait for deals from renewable energy providers to return.

Our Power House report will show you how much energy your everyday appliances use to help you see if you can run your home more efficiently. 

The table below lists the cost of different appliances in each room using their average power rating and the costs are based on the average unit rates according to the energy price cap, the current level of which will last until October 2023. 

Which kitchen appliances use the most energy?

We tend to spend most of our time in the kitchen, so a lot of a household’s energy usage is going to come from the various appliances used in cooking or storing food.

Freezers are more expensive to use than fridges (at £94.86 and £56.44 per year respectively), while the lowest-cost appliance is an ice cream maker, which uses 0.035 kWh and costs 56p per year.

Tips on how to reduce appliance energy usage

  • Choose appliances with a high energy efficiency rating wherever possible - A-rated devices are the most energy-efficient

  • Turn appliances off at the plug when you aren’t using them

  • Switch off lights when leaving the room

  • Swap halogen light bulbs for LED versions which last longer and cost less in the long-term 

  • If possible, set a heating schedule for the times when you’re using certain rooms or know you’ll be at home

What’s the impact of energy saving on Net Zero? 

Reducing your appliance energy outputs can reduce your monthly bills and also help reduce your carbon footprint. Energy consumption in the UK contributes 95.8 million tonnes, which is 21% of the country’s overall carbon production. The UK has pledged to reach Net Zero emissions by 2050, which means having to increase renewable energy sources, as well as reducing carbon emissions from things such as transport, diet and waste. 

Uswitch's energy expert Ben Gallizzi says: 

“With the cost of living increasing, many of us are trying to find ways to cut down on our energy bills. It’s easy to think that small appliances may not have a big impact on your overall energy bill, but surprisingly they can often have the most impact. 

“Getting used to turning off electrical items at the plug sockets after use; making sure lights are turned off if rooms aren’t being used; and using more energy efficient appliances wherever possible can all shave pounds off your bills.”
