Create a healthy, energy-efficient home

There are simple changes you can make to help make your home warmer and drier.

Top tips to make your house warmer, drier and more energy-efficient

  • Trim trees or plants that are blocking any windows, and make sure your curtains are open all day to take advantage of the sun in winter.
  • Check your ceiling and underfloor insulation – if you can see the ceiling joists inside the roof cavity, it needs to be topped up. Check for any gaps in the insulation at the same time.
  • Stop draughts – make sure your doors and windows fit their frames properly, block up old fireplaces, and use draught-stopping tape or seal and draught excluders.
  • Set your heating system to 18 degrees in the bedroom, and 21 degrees in the living room. If you have a portable or panel heater, invest in a plug-in thermostat. This will keep you warm and healthy without wasting energy.
  • Make sure your heating system is clean and efficient – clean your heat pump's filter regularly, and have your chimney or flue swept once a year. Replace your inefficient and costly unflued gas heater.
  • Install lined curtains that reach to the floor, and are covered by a pelmet or face-fitting tracks at the top. This can be as effective as double glazing.
  • Manage moisture in your home effectively:
    • get externally ducted extractor fans for your bathroom and kitchen
    • dry clothes outside, or use a drier for a short amount of time (which will be more efficient than using a dehumidifier)
    • put down a groundsheet to help with rising damp
    • wipe condensation off your windows in the morning
    • open your windows for at least 20 minutes a day.
  • Check your shower's flow rate – if it fills a 10L bucket in less than a minute, it's wasting water. Consider a water-efficient shower head or a flow control disc to keep the flow rate to 9L/minute.
  • Insulate your hot water cylinder and pipes, either with a cylinder wrap or some old blankets.
