Ventilation checklist

Try to make ventilation a part of your daily routine. Here’s a simple checklist for ventilating your home.

Doors and windows

The simplest and cheapest way to ventilate your home is to open doors and windows regularly, allowing fresh air into your home.

In summer

Open windows and doors in different parts of your home to create a cross-draught, which will circulate air and help keep your house cool and dry.

In winter

Air your house at least once a day for a few minutes with wide open doors and windows to create a cross-draught. This will quickly replace stale indoor air with fresh outdoor air.

When you turn off heating

To avoid condensation problems, ventilate when you turn off the heating, for example before you leave the house in the morning and just before you go to bed.

Overnight

Ventilating your bedroom overnight is also important for maintaining air quality, reducing excessive moisture and the risk of mould growth. Where possible keep windows slightly ajar on a hinge - a finger’s width should be enough.

Extractor fans

Make sure you’ve good extraction systems in wet areas of your home, such as your bathroom, laundry and kitchen. Fans or extractors should vent to the outside, not into your ceiling space or where they will recirculate damp air. Make sure extractor fans are:

  • properly sized and located - for the type of room.  Ask your supplier for advice.
  • turned on before having a shower or bath - and shut the bathroom door. Leaving the bathroom window open slightly allows air flow into the bathroom and will improve the extractor fan's effectiveness.
  • run for a few minutes after a shower or bath - with the bathroom door shut.
  • cleaned regularly - to maintain their performance.
