Heating and cooling

Heating and cooling your home generally accounts for a large part of your home’s overall energy use. Explore how to improve your energy efficiency with these tips.

  1. Set and forget for the season

    End any thermostat battles in your home by setting your system to 24°C in summer and 18°C to 20°C in winter. These are comfortable temperatures in both seasons, especially compared to the conditions outside!

    Effort: Easy enough

  2. Enjoy a fresh start

    The start of a new season makes the perfect time to review your energy use and efficiency. Start by making sure your heating and cooling is set up to run efficiently for the conditions ahead.

    Effort: Some effort

  3. Choose the right size for your home

    Make sure your heating and cooling system or appliance is the right solution for the size of your home and your lifestyle. If it’s too large, it could be wasting energy - and if it’s too small, it could be working harder than it is designed to operate.

    Effort: A bit of effort

  4. Don't crank your air-con

    It’s more energy efficient to heat or cool your house slowly over time, instead of cranking your air conditioner up or down.

    Effort: A bit more effort

  5. Use your tech

    If you have an air-con system which you can run through an app - learn how to use it! You could set it to cool or warm your house slowly before you get home or before you even get out of bed in the morning, rather than cranking it.

    Effort: A bit more effort

  6. Seal the cold or warm air in

    Use a door snake - or even a rolled-up towel - to help stop air escaping from under your doors.


    Effort: Easy enough

  7. Use a pedestal or ceiling fan

    Fans are a much more energy-efficient way to stay cool and keep the air moving, compared to air-conditioning.

    Effort: Some effort

  8. Book in a service

    Having your heater and air-conditioner serviced could help you to keep it running efficiently. Check with your manufacturer for recommendations.

    Effort: A bit more effort

  9. Add a layer

    When the weather is getting chilly, reach for a jumper, hoodie or your favourite wearable blanket before you decide to switch on the heating.

    Effort: Easy enough

  10. Sun in, sun out

    In winter, open your blinds or curtains in the middle of the day to let the warm sun in. In summer, use your blinds or curtains to block out the sun’s heat.

    Effort: Easy enough

  11. Get warm and cosy

    On cold winter nights, rug up with some warm PJs and your favourite throw rug. At bedtime, try a few extra blankets instead of an electric one.

    Effort: Easy enough

  12. Electric blanket on, room heater off

    Once you’re in your warm bed, you probably don’t need to heat the whole room.

    Heat can escape from your oven seal, which could mean your oven uses more electricity. Check your oven seal is in good condition and replace if needed.

    Effort: Some effort

  11. Use your oven window

    If you want to check your masterpiece-in-the-making, look through the window rather than opening the oven door. Each time you open the door, hot air escapes which means your oven needs to use more energy to heat up again.

    Effort: Easy enough

  12. Put your air fryer to work

    Since your air fryer is compact and doesn’t need a lot of preheating time, it’s likely to use less electricity than your oven. Consider what you can cook in your air fryer when you’re planning your meals.

    Effort: Easy enough

  13. Make the most of your microwave

    Your microwave is likely to use a lot less energy than your oven, so use it for cooking and reheating when you can.

    Effort: Some effort

  14. Switch the microwave off at the wall

    When your microwave is on standby, it’s just an expensive clock. Only switch it on when you need it.

    Effort: Some effort
