I would like to inform the House that a written answer given by the previous Parliamentary Under Secretary of State (Minister for Prevention, Public Health and Primary Care) on 18 May 2021, Official Report 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 H2O2 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.
