Mould: A Category Two Health Risk
Mould is more than just an unsightly nuisance, it poses serious health risks, particularly when it contaminates indoor environments. In the UK, under the Housing Health and Safety Rating System, mould is classified as a Category 2 health hazard. This is because mould exposure can lead to a range of adverse health effects, especially in vulnerable individuals such as children, the elderly, and those with respiratory conditions.
A Category Two health risk refers to biological hazards that can cause illness or discomfort when inhaled, ingested, or come into contact with skin. Mould fits this classification because it releases spores and mycotoxins into the air, which can trigger allergic reactions, respiratory issues, and, in severe cases, chronic illness.
Common symptoms of mould exposure include coughing, sneezing, skin irritation, and watery eyes. In more severe cases, individuals may experience asthma attacks, chronic fatigue, headaches, and long-term respiratory conditions. The risks are heightened in damp, poorly ventilated areas where mould thrives, making it essential to address moisture problems promptly. Individuals that are categorised as vulnerable, including those with pre-existing health conditions, weakened immune systems, children, and the elderly are particular vulnerable to the effects of mould exposure.
One of the most significant recent developments in mould-related health protection is Awaab’s Law. Named after Awaab Ishak, a two-year-old who tragically died due to prolonged exposure to mould in his family’s rented accommodation. Awaab’s Law, stemming from the Social Housing Regulation Act 2023, mandates that social landlords and housing associations in the UK must address damp and mould hazards, investigate hazards with 14 days, and complete repairs within a reasonable timeframe, with emergency repairs within 24 hours. The law will be enforced from October 2025 and will expand to a wider range of hazards beyond damn and mould from 2026. Awaab’s Law underscores the importance of maintaining safe living conditions and holds property owners accountable for mould prevention and remediation.
To minimise exposure, regularly inspecting areas prone to dampness – such as bathrooms, kitchens, and basements – and addressing leaks and condensation is crucial. Professional mould remediation is recommended when contamination is extensive.
