Question to the Department for Education:

To ask the Secretary of State for Education, whether her Department issues guidance for schools on maintaining safe CO2 levels in classrooms.

The department has published ‘Building Bulletin 101’, which provides non-statutory guidance on ventilation, thermal comfort and indoor air quality in schools. This is available at: https://www.gov.uk/government/publications/building-bulletin-101-ventilation-for-school-buildings.

The department has also produced guidance on using CO2 monitors and managing ventilation, which is available at: https://www.gov.uk/guidance/using-co-monitors-and-air-cleaning-units-in-education-and-care-settings.

Further guidance on ventilation is included in the ‘Good Estate Management for Schools guide’, which is available at: https://www.gov.uk/guidance/good-estate-management-for-schools/health-and-safety.
