I would like to inform the House that a written answer given by the previous Parliamentary Under-Secretary of State, the Minister for Prevention, Public Health and Primary Care, on 18 May 2021, parliamentary question 496, was incorrect.
In the response to written question 496, we stated that Public Health England had undertaken an assessment of technologies regarding inactivation methods against covid-19, including the use of UV-C and H202 vapour. However, this information was inaccurate. Public Health England did not make any such assessment. Rather, the UK Health and Safety Laboratory assessed the potential merits of hydroxyl free radical air purification technologies in response to the covid-19 outbreak.
