My noble friend is absolutely right: local councils are responsible for enforcing standards in the private rented sector and have a duty to take action where they find hazards at the most dangerous category 1 level. The Secretary of State has asked all local housing authorities to do everything in their power to improve the conditions for tenants and to have particular regard to high-score category 2 damp and mould hazards when enforcing current standards. The Secretary of State has also asked councils to provide an assessment of damp and mould issues particularly affecting private rented housing in their area. The department is currently analysing their responses to determine what needs to be done to address the issues raised by my noble friend.
