Over 26,000 young children were admitted to hospital last year with lung conditions potentially linked to mould and damp, BBC Panorama revealed on Monday (10 February).
Panorama spoke with a mother whose son, Aziyah, began to develop health issues and was later diagnosed with asthma as a result of the black mould in their Brighton home.
"No matter how loud I scream, I'm not being heard," 25-year-old Sinead says.
More than half a million rented homes have black mould issues in England, according to a 2023 government survey.
