Top tips for winter: preventing condensation & keeping warm


Cold weather means cosy jumpers, mugs of hot chocolate and fun in the snow, but it can also cause a build up of condensation in your home and can make some health problems worse.

Preventing mould & condensation

In the winter months, moisture in the warm air hits cold surfaces which causes condensation to form. A buildup of condensation can cause mould.

Follow our top tips to help prevent condensation in your home.

  • Keep your home ventilated. Change the air once a day by opening a window for a small time each day. Keep window trickle vents open, and air vents uncovered.
  • Keep your extractor fan on to extract moisture. They cost less than £1 per month to run and use less energy than a lightbulb.
  • Keep doors closed and windows open when bathing and cooking.
  • When filling a bath, run the cold water before the hot water. This will reduce steam which leads to condensation.
  • Keep lids on pots and pans when cooking to prevent moisture escaping.
  • Wipe off any water droplets on windows.
  • Dry clothes outdoors, or in a room with doors closed, windows open and the extractor fan on. If using a tumble dryer, make sure the ventilation pipe runs to the outside of your home.
  • Leave a gap between walls and furniture to allow air to circulate.
  • Keep the heating at one constant temperature.
  • Use a fungicidal spray on affected areas.

Keeping warm

Follow our top tips to help keep you warm in winter.

  • Patch up any draughts in your home by filling in the gaps around windows and doors with a draught excluder.
  • Close curtains before it gets dark and whilst you’re out of the house to stop warmth escaping from the windows. Consider investing in some thermal curtains.
  • Cover wooden floors with rugs to stop warmth escaping.
  • A good temperate for heating is 18-21°C. Set it to come on just before you get up/or in and switch off after you’ve gone to bed.
