■ Wipe condensation off windows and walls. Open a few windows slightly throughout the house for one to two hours a day. Use an extractor fan in the bathroom.

■ Open windows slightly if using portable gas heaters or use a dry source of heat such as an electric heater or wood burner.

■ Hang washing outside to dry. If using a clothes drier, ensure it vents outside or a window in the laundry is kept open.

■ Keep lids on pots when cooking and let steam out by opening a window. Use an extractor fan if you have one.

■ White vinegar is the best way to kill or clean mould.
