Do1Thing - Top Tips on Saving Energy

Do1ThingOur Do1Thing website provides an energy saving action for every day of the month. Take a look at for top tips on how you can save energy and save money.

Below we’ve also compiled a quick list of easy tips on how you could save on your annual energy bill and on keeping warm.

Around the house:

  • Set your room thermostat to between 18-21ºC to ensure your living space is kept at a healthy temperature. If it is higher than 21ºC, turning it down by 1ºC could save you around £65 a year. If you have central heating, you can adjust the temperature by using a thermostat in the room you use most and the radiator valves.
  • In rooms you use less often, turn the heating down using the radiator valves.
  • Shut doors to keep heat in the rooms used the most and stop draughts from badly fitting windows and doors.
  • Close curtains as soon as it gets dark; this will reduce draughts and heat loss through the windows.
  • Replace your light bulbs with energy efficient ones. One bulb can save around £50 over its lifetime of about 15 years.
  • When a room is empty, make sure that the lights are turned off, saving around £10 per year.
  • Having a shower instead of a bath will reduce hot water consumption by about 50%, saving around £45 per year. Fix dripping taps as soon as possible; one hot water tap can waste the same amount of water as one hot bath in a week.
  • Don’t leave appliances on standby or on charge unnecessarily, it cost between £50 and £90 per year to leave items on standby.
  • Switching a plasma TV for an LCD TV of the same size could save around £25 per year.
  • Is your water too hot? If you have a hot water tank check your cylinder thermostat to make sure it is set to exactly 60ºC/140ºF. (To prevent Legionnaires your hot water tank must never be less than 60ºC/140ºF.)

In the kitchen:

  • Put lids on saucepans; food will cook quicker and save you money.
  • Do not leave the fridge door open longer than necessary and defrost it regularly.
  • Use your washing machines only when full. Setting the temperature to 30°C not 40°C will save around £10 per year – most washing detergents work well at this temperature.
  • Drying clothes outside in the summer months will also save you up to £20 per year.
  • Only boil as much water as you need, both when cooking and using the kettle.
  • If there is moisture in the air (for example, from drying clothes or cooking), close the door and open the window or put on a fan; once the moisture has gone, then close the window and switch off the fan to keep heat in.
