Our 12 top tips to save energy at home
In addition to the many ideas you'll find on this page, watch our video for our top 12 tips to save energy at home.
Choosing your supplier
By law your electricity supplier has to tell you if you could save money by changing to another tariff. However, this may not be easy to find on your monthly bills.
There is no harm in contacting your supplier to ask them directly, they'd be glad to help you if it means you don't take your business elsewhere.
It pays to shop around to compare your energy supplier's rates with the marketplace:
There are free online comparison sites which can make this very quick and easy, such as Uswitch or Switcheroo.

Heating your home
DIY draught-proofing will be cheaper than paying a professional to do so, which can cost around £250 for a whole house. Unless you have an old property with single-glazed windows, draught-proofing can be fairly simple. Read guidance from the Energy Saving Trust.

The Energy Saving Trust estimates that fitting a more efficient shower head can reduce combined heating and water bills by around £60.
Using clothes racks indoors or hanging washing outside in warmer weather can reduce your energy consumption.
Almost all appliances can be switched off standby without affecting their usual functionality. Check the device manual if you are unsure.
Insulating your water tank, or increasing the thickness of an existing jacket to 80mm, keeps the water warmer for longer. Radiator reflector panels can help reduce heat loss through external walls.
According to the Energy Saving Trust, ‘DIY hot water tank installation on an uninsulated tank would cost around £20, while primary pipe insulation should cost around £18.’ This could save up to £175 per year on energy bills, based on July 2024 fuel prices.
Boil only as much water as you need to avoid the kettle working harder than necessary.
Other ways to help reduce your energy consumption
- Adjust your heating controls
- Turn radiators off in unoccupied rooms
- Get a smart meter (they are usually free)
- When cooking, cover pans with lids and use a cooker ring that is the same size as the pan
- Wash clothes at 30°C
- Fitting efficient taps or tap aerators
- Fill your dishwasher and washing machine to appropriate levels
- Turn off lights when they are not needed, and switch to LED bulbs
