​Insulating your home

Even small amounts of insulation can save you money on your fuel bills and reduce the amount of carbon dioxide you create. Carbon dioxide is the main greenhouse gas that contributes to global warming.

Improving your heating

A modern and efficient heating system could save you money on your fuel bills based on estimates from the Energy Saving Trust. A new boiler could use 40 per cent less energy than a ten-year-old boiler.
If you can’t afford to replace your boiler or heating system, just changing the heating controls could save you almost 20 per cent on your heating bills.
For gas central heating, you should have controls such as:
  • boiler thermostat
  • timer or programmer
  • room thermostat (there is usually only one room thermostat in a house or flat)
  • thermostat valves on radiators.

Energy saving tips

There are things you can do in your home every day which will not cost you money but will save you money on your fuel bills.

Heating and hot water energy saving tips

  • Turn your thermostat down. Reducing your room temperature by 1°C could cut your heating bills by up to 10 per cent (the recommended temperature for a living room is 21°C and 18° C for a bedroom).
  • Set your heating and/or hot water to come on only when you need them to rather than having them on all the time.
  • Check the temperature of your water. It might be too hot. Your cylinder thermostat should be set at 60°C/140°F.
  • Close your curtains at dusk to stop heat escaping through the windows.
  • Use draught excluders or towels to block out drafts around windows or doors.
  • A dripping hot water tap wastes energy and in one week wastes enough hot water to fill half a bath. Fix leaking taps and make sure they are fully turned off.

Electricity saving tips

  • Always turn off the lights when you leave a room.
  • Don't leave appliances on standby.
  • Don’t leave laptops and mobile phones on charge for longer than they need to be. The charger will still use electricity if it is not switched off after the laptop or phone has finished charging.
  • Try to fill up the washing machine, tumble dryer or dishwasher every time you use them. One full load uses less energy than two half loads.
  • Only boil as much water as you need (but remember to cover the elements if you are using an electric kettle).
  • Use energy saving light bulbs. They last up to 10 times longer than ordinary bulbs. 

Laundry – saving energy

  • Do your washing less frequently by making sure the washing machine is full every time. You will use less water and electricity.
  • Where possible, use the economy setting on your washing machine or wash at 30° C
  • Dry your clothes outside or on a clothes horse rather than in a tumble dryer.

Food waste tips

  • Freeze your leftovers or put them in the fridge and eat them the next day. Wasted food creates carbon dioxide (CO2), a major cause of global warming.
