Free and low cost energy saving measures

Here are some other measures you can fit that are free or don’t cost a lot, but will help you to stay warmer in the winter and save money.


  • If you have gas central heating use a timer switch and your thermostat for maximum efficiency. It’s good to have Thermostatic Radiator Valves (TRV’s) as well. TRV’s let you control the temperature of each individual radiator, so even if your central heating is on you don’t have to heat rooms you are not using. Have a look at our video on the right to see how to correctly set your heating controls.
  • Turn your thermostat down by just 1°C – this can save you as much as £60 per year. Don’t have your heating up too high, for most people 18-21°C is just right for living spaces.
  • Make sure your immersion boiler isn’t on – running it can cost up to 50p an hour.
  • Wear more jumpers, socks and slippers around the house, and put an extra blanket on the bed so you won’t be tempted to turn the heating up.
  • If you have gas central heating use a timer switch and your thermostat for maximum efficiency.
  • Don’t leave lights on and replace your lightbulbs with low energy LED bulbs.
  • Switch off appliances that you aren’t using – even chargers continue to use electricity when they aren’t charging.
  • Don’t leave appliances on standby – on average UK households spend £30 a year powering appliances left in standby mode.
  • Keep your fridge and freezer well stocked. This saves energy because there’s less space for warm air to enter when they are opened so they don’t need to work as hard.
  • Make sure that dishwashers and washing machines are full before you use them, and always use the most efficient setting (newer appliances often have an Eco mode). Most clothes can be washed well at 30°C.
  • If you’re going to boil the kettle, only put in the water you will use. You can measure this first using the cup or the mug you will be filling.
  • Air-dry your laundry rather than tumble drying it if you can. Whilst efficient models (such as heat pump technology) exist, tumble dryers are still one of the most expensive items to run in the home.
