Breathing Easier: Tackling Childhood Asthma

Guest: Catherine Sutton, CEO of Airborne Allergy Action, hosted by Andy Cameron-Smith, Communications Director at Healthy Homes Hub 

What if the triggers behind a child’s asthma weren’t just genetic or seasonal—but hidden in the home itself? 

In this episode, Catherine Sutton shares her journey from parent to campaigner after discovering how everyday allergens—dust mites, mould, pet dander, even pest droppings—can quietly drive asthma attacks. Through Airborne Allergy Action, Catherine now works to make homes healthier and to ensure the link between housing and respiratory health isn’t overlooked. 

Catherine and Andy talk about why small environmental changes—like using mite-proof bedding and sealed HEPA vacuums—can make such a difference, and why the evidence already exists within NHS guidance and public health research. They explore what needs to happen next to bring this knowledge into everyday housing practice. 

Key takeaways 

• The NHS National Asthma Bundle already recommends reviewing the home environment for triggers such as dust mites and mould—but implementation is inconsistent. 

• Studies show that mite-impermeable bedding and HEPA vacuuming can cut emergency hospital admissions for children sensitised to dust mites. 

• International models prove that simple healthy home interventions deliver both health improvements and cost savings. 

• With Awaab’s Law housing providers now have a statutory duty to act quickly on damp and mould—bringing health and housing closer together.

Practical steps for housing providers 

1. Act early: Check bedrooms first—these are often where the highest exposures occur. 

2. Equip homes properly: Provide or recommend sealed HEPA vacuums and mite-proof bedding where asthma has been reported. 

3. Work with health teams: Create referral pathways with local NHS asthma nurses or respiratory specialists. 

4. Stay compliant: Review your damp and mould response process to ensure it aligns with Awaab’s Law timelines. 

5. Educate and empower: Share allergy-awareness materials with maintenance teams and residents alike
