Keeping your home cool during a heat wave

With temperatures rising again, a few simple changes around the home can make a big difference in keeping indoor spaces cooler and more comfortable.

The key is to prevent heat from entering during the hottest parts of the day, encourage airflow when temperatures drop, and reduce sources of heat inside the home.

Top tips for staying cool at home
  • Hand closing blindsKeep windows and curtains closed during the day to prevent hot air and direct sunlight from heating up your home.
  • Open windows during the early morning or overnight when temperatures are lower. For the best airflow, open windows on opposite sides of the house to create a cooling breeze.
  • Use fans effectively when temperatures are 35°C or below:
    • Place a bowl of ice or a frozen bottle of water in front of the fan to help circulate cooler air around the room.
    • In the evening, position a fan facing out of an open window to help push warm air out and draw cooler air in.
  • Spend time in shaded or north-facing rooms, which are often cooler than rooms exposed to direct sunlight.
  • Avoid using ovens and other heat-generating appliances during the hottest parts of the day where possible.
  • Open your loft hatch to allow rising hot air to escape into the loft space
  • Make the most of extractor fans. Leave bathroom and kitchen extractor fans running for a short time after showering or cooking. This helps remove warm, humid air and improves airflow throughout the home.
