Save energy and save money

You can save lots of money with a few simple changes around your home.

These no-cost measures involve subtle changes to your habits which will soon become second nature.


  • Turn the room thermostat down by 1 °C. This can save up to £30 a year.
  • Don't put curtains or furniture in front of a radiator - they will block the heat.
  • Pull on a jumper or warmer layers rather than turning the heating up.

Hot water

  • Turn the thermostat on your hot-water tank down to 60 °C rather than add lots of cold water to your bath. Saving: £10 a year.
  • Put the plug in the basin or sink, especially when running hot water. Otherwise you are pouring money down the drain.
  • An ordinary shower uses only two-fifths of the water needed for a bath. Power showers use as much as a bath, and sometimes even more.


  • Match the size of the ring to the size of the saucepan or you will be paying to heat air.
  • Put a lid on saucepans so the contents heat quicker and you use less energy.
  • Cook several different foods on one ring with a pressure cooker or steamer.
  • Microwaves save money because you don't waste energy heating containers or air.


  • Switch off appliances such as microwaves, TVs, stereos and computers. 85% of the energy used by a DVD player is wasted when it is on standby. Saves up to £11 a year.
  • Unplug equipment once fully charged otherwise they keep drawing electricity.


  • Avoid leaving fridge doors open. Each minute the door is open takes three minutes of energy to cool down again.
  • Avoid putting hot or warm food straight into the fridge. Allow it to cool first.
  • Defrost your fridge regularly to keep it running efficiently and cheaply. If it seems to frost up quickly, check the door seal.
  • Keep the freezer in a cool room or garage.

Washing machine and dishwasher

  • Wash laundry loads on the low-temperature programme.
  • Only put the washing machine or dishwasher on when you have a full load (but don't overfill).

Drying & ironing

  • In summer dry your clothes outside and enjoy the fresh smell that only comes from line-dried clothes.
  • Don't dry clothes on a radiator. It stops heat reaching the room, creates damp and encourages mould.
  • If you have to use a tumble dryer, don’t put really wet clothes inside. Wring them out or spin-dry them first.
  • Only iron if you have to. Choose fabrics that don't need ironing. And do you really need to iron your bed sheets?


  • Mirrors and light-coloured walls reflect daylight, making maximum use of natural light.
  • De-clutter window ledges to get the most daylight in your home. Pull curtains back during the day and keep plants trimmed so they don’t block incoming light.
