In July 2020, the Scientific Advisory Group for Emergencies published a paper on the application of UV disinfection, visible light, local air filtration and fumigation technologies, particularly hydrogen peroxide vapour using H2O2 to microbial control regarding COVID-19 transmission. The paper is available at the following link:

Public Health England (PHE) has undertaken assessments of inactivation methods against COVID 19, including the use of UV-C and H2O2 vapour, with further evaluations ongoing. PHE published guidance on infection prevention and control for COVID-19. Standard use of UV-C and H202 technologies are not recommended as these could be used to supplement existing cleaning and ventilation rather than replace them. Their guidance is available at the following link:
