Question to the Department of Health and Social Care:

To ask the Secretary of State for Health and Social Care, what assessment he has made of the potential impact of poor air quality in (a) ambient air and (b) indoor air on different age groups of people in England.

Poor air quality is a major public health risk in the United Kingdom. An estimated 29,000 to 43,000 deaths were attributable to long-term exposure to ambient air pollution in the UK in 2019 among adults aged 30 years old and over.

Indoor residential exposure to damp and mould was associated with approximately 5,000 cases of asthma and 8,500 lower respiratory infections among children, those who are aged between zero to 14 years old, and adults, those who are aged between 15 to 49 years old, in England in 2019.

The UK Health Security Agency (UKHSA) contributed to a report by the Royal College of Physicians in 2025. This contained data on new cases of mortality, myocardial infarction, asthma, lung cancer, and other conditions, attributable to a range of air pollutants in 2019 and predicted for 2040, among children, those over 30 years old, over 60 years old, and at all ages. The report is available at the following link:

The Department’s 10-Year Health Plan sets out how the Government will act to reduce the health harms of air pollution. This includes action to reduce harm from ambient air pollution and tackling poor indoor air by improving the standard of rented homes with relation to damp and mould.
