Do landlords have a legal duty to fix damp and mould problems?

Yes, landlords in the UK have a legal responsibility to ensure their properties are fit for tenants to live in. Under the Homes (Fitness for Human Habitation) Act 2018 and existing landlord obligations, damp and mould that affects health or safety must be addressed. If mould is due to a tenant’s lifestyle, such as poor ventilation, the landlord may still need to advise and support improvements. Ultimately, if damp or mould is damaging the property or making it unsafe, landlords are required to act. Tenants can raise concerns formally if problems aren’t resolved.
