You need to stop closing your window vents in winter – experts reveal you're doing more harm than good

Pretty bedroom with white walls, pink panelling and blind, white bedding, with pink and green cushions, and a silver grey traditional radiator under the window.

Yes, it's really cold outside. Yes, it's the time of year when condensation, damp and mould really thrive, but experts want you to stop closing your window vents in winter, as keeping them closed can actually contribute to these winter problems.

While you may be tempted to keep your window vents (also known as trickle vents) shut during the winter to stop any heat escaping, it is ultimately a bad idea. Especially, considering that keeping them open is a lesser-known hack that prevents condensation build-up on your windows.
