Fact sheet: Damp, condensation and mould in residential property

Housing quality and energy efficiency underline the progress made, and the scale of the challenges still facing the sector is the headline finding in the EHS (English Housing Survey). Policy ambitions must have clear guidance, realistic timescales, workable exemptions, and sustained funding to reflect the diversity of the housing stock. Active involvement by qualified property professionals is also a must if raising standards is to be achieved.

A House of Commons Public Accounts Committee report states that the UK Government’s energy efficiency installation initiative has suffered serious failings at every level, leaving more than 30,000 homes with defects after external and internal wall insulation was installed through ECO4 and the Great British Insulation Scheme.

After a sustained consultation with members and a Propertymark campaign, the UK Government has confirmed an enforcement date of 2035 for the Decent Homes Standard in the PRS. Key exemptions and removal of age-based replacement rules have also been confirmed in a UK Government statement on 28 January 2026.

New regulations have been laid in the Scottish Parliament which, if passed, will place clearer and more time-bound duties on landlords and agents to investigate and address damp and mould in both private and social rented homes. Clear standards, realistic timescales and consistent enforcement are essential if these reforms are to improve housing conditions without reducing supply or creating unintended consequences.
