Question to the Department for Business, Energy and Industrial Strategy:

To ask the Secretary of State for Business, Energy and Industrial Strategy, what steps he is taking to issue guidance to commercial property owners who wish to (a) improve or (b) modify their air flow, heating and air extraction systems to reduce the risk of spreading the virus.

Evidence shows that proper ventilation can be used to mitigate the transmission risk of COVID-19, alongside other measures. Ventilation into the building should be optimised to ensure the maximum fresh air supply is provided to all areas of the facility wherever possible.

Our workplace guidance includes a number of steps that will usually be needed to ensure that ventilation systems provide a good supply of fresh air. It is important that businesses check whether ventilation systems need to be services or adjusted. If businesses and employers are unsure we advise they seek advice from their heating ventilation and air conditioning (HVAC) engineers or advisers.
