Ventilation and air conditioning during the coronavirus (COVID-19) pandemic

Removal of most coronavirus (COVID-19) restrictions

This page is up to date following the removal of most restrictions in England. There are different regulations and guidance to follow for Scotland, Wales and Northern Ireland.

The latest advice on keeping workplaces safe will help you assess the risks and continue to reduce COVID-19 transmission. This includes links to information on vaccination, as well as on testing, tracking and tracing (including where variants are spreading).

6. Balancing ventilation with keeping people warm at work

Providing adequate ventilation does not mean people have to work in an uncomfortably chilly or cold workplace.

There are simple steps you can take to make sure your workplace is adequately ventilated without being too cold:

  • Partially opening windows and doors can still provide acceptable ventilation while keeping workplace temperatures comfortable
  • Opening higher-level windows will probably create fewer draughts
  • In occupied rooms relying on natural ventilation, air the space by opening windows and doors as fully as possible to regularly provide additional fresh air.
  • This can be done while people leave the room for a break. For example, 10 minutes an hour can help reduce the risk from virus in the air, depending on the size of the room
  • If the area is cold, relax dress codes so people can wear extra layers and warmer clothing
  • You could set the heating to maintain a comfortable temperature even when windows and doors are open

Consider providing additional sources of heating if required. Only use fan convector heaters if the area is well ventilated.

This page is reviewed regularly and updated to reflect any changes in the guidance.
