The Health Risks of Mould in the Home

Mould isn't just unsightly — it can have serious effects on health, particularly for children, the elderly, and those with respiratory conditions.

Mould in the home is far more than an aesthetic problem. Research has consistently linked indoor mould exposure to a range of health effects — some of them serious.

Who Is at Risk?

Everyone is affected by mould to some degree, but the most vulnerable groups are: - Children (whose immune systems are still developing) - The elderly - People with asthma or other respiratory conditions - Those with allergies - Anyone with a compromised immune system

Health Effects of Mould Exposure

Respiratory problems — Mould spores are inhaled and can trigger wheezing, coughing, and breathlessness. In people with asthma, mould exposure can provoke serious attacks.

Allergic reactions — Runny nose, watery eyes, sneezing, and skin rashes are common in people sensitive to mould spores.

Sinusitis — Persistent mould exposure can inflame the sinuses, leading to chronic sinusitis.

Fatigue and headaches — These are common reported symptoms in households with significant mould problems.

Black mould (Stachybotrys) — While rarer than common household mould, this type is particularly associated with mycotoxin production and more severe health effects.

The Legal Picture

Under the Homes (Fitness for Human Habitation) Act 2018, landlords are legally required to ensure rental properties are free from serious mould problems. Tenants with mould issues have legal recourse.
