Damp, Cold, and Poor Housing – Why It Matters for Lung Health

This briefing from the House of Commons Library (2025) looks at how poor housing conditions—especially damp, mould, and cold homes—affect health and what’s being done about it in the UK.

Main Points

• Health risks are serious
  Living in damp or mouldy homes increases the risk of respiratory problems, particularly for people with existing lung disease like aspergillosis, asthma, COPD, or bronchiectasis.

• Children and vulnerable adults
  Young children, older adults, and people with weakened immune systems are most affected. Damp and mould can trigger flare-ups, worsen breathing symptoms, and increase infection risk.

• Mental health impact
  Poor housing is linked to stress, anxiety, and depression. Worrying about your home can also worsen physical symptoms, especially if you avoid using rooms with mould or limit heating to save costs.

• Cold homes add to the problem
  Cold airways can make breathing more difficult, weaken the immune system, and increase the chance of winter infections.

• Wider health effects
  Damp and cold can also affect heart health, bone/joint pain, and overall wellbeing.

What’s Being Done

• Legal responsibilities: Landlords must keep homes safe and fit to live in under UK law. This includes dealing with serious damp and mould.

• Government programmes:

  • Funding for improving insulation and heating in social housing.

  • Advice services for tenants.

  • Local councils can take action if landlords fail to address hazards.

• Public health guidance now recognises the link between housing and chronic illness, with stronger advice for early intervention.

What This Means for Aspergillosis Patients

• Stay alert to symptoms: If your cough, breathlessness, or fatigue worsen at home, check for damp, mould, or poor heating.

• Act early: Report problems to your landlord or council quickly—prolonged exposure can worsen lung damage.

• Medical link is recognised: You are more likely to be taken seriously now, as official guidance acknowledges the health risks.

• Keep records: Photos, symptom diaries, and GP notes can support housing complaints.
