How to save energy

Energy efficient homes help cut bills and save money.

Please note that these figures are based on the savings a 3 bedroom semi-detached house would make, and are sourced from the Energy Saving Trust.
  1. Use energy saving light bulbs

    Replacing just one old light bulb with an energy saving one can cut lighting costs by up to £50 over the lifetime of the bulb. And new-style bulbs last up to 12 times longer than old light bulbs.

  2. Turn down your thermostat

    Turning down your thermostat by just 1 degree could cut your heating bills by up to 10% and save you around £85 a year. If you install a thermostat, it could save you up to £70 a year. A hot water tank thermostat can save around £30 a year.

  3. Don’t leave on standby, switch off

    UK households spend an average of £35 a year by leaving appliances on standby, so make sure you switch appliances off at the plug. Research has also shown that leaving electrical items like laptops on charge after the battery is full costs around £3 a year.

  4. Fix dripping taps

    A dripping hot water tap can waste enough hot water to fill half a bath in just one week. Fix leaking taps and make sure they’re fully off.

  5. Draught proof your home

    Draught proof your home and save an average of £55 a year.

  6. Insulate your hot water tank

    An insulation jacket is a good investment. It costs around £15 but can save around £45 a year on your heating bill, paying for itself in less than six months.

  7. Compare Your Energy

    Keeping your home energy efficient is one of the best ways of managing your energy bills. Compare how energy efficient your own home is with people in your local area by visiting the Compare My Energy website.

  8. Use an electricity monitor

    Electricity monitors show you in real time how much electricity you are using. This can help you make decisions about your energy use and become more efficient. At the moment, you can get an electricity monitor from around £25 online. They're easy and quick to install.

  9. Insulate

    Insulating your home is the best way to save energy. A third of the cost of heating is lost through the walls. Cavity wall insulation can save you up to £140 per year on your heating bills, and loft insulation can save you £175 a year.

    Even if you already have some loft insulation it’s worth considering putting in an extra layer. The Energy Saving Trust recommends having 27 centimetres of insulation installed in your loft to get the maximum benefits.

  10. Replace your old boiler

    Your boiler accounts for two thirds of the energy you use each year. Upgrading to an A-rated high-efficiency condensing boiler could make a big difference - up to £300 a year.

    If you're disabled, have children, or are on benefits you may qualify for help to buy a new boiler. Call the free Home Heat Helpline on 0800 33 66 99 for more advice.
