CIOB and CIH Issue Joint Guidance on Social Housing Damp and Mould

The Chartered Institute of Building (CIOB) and the Chartered Institute of Housing (CIH) have released joint guidance to address damp and mould in social housing. The document provides practical framework strategies, industry case studies, and clear methodologies for diagnosing and remediating structural moisture issues.

A Systemic Issue for Social Housing

Damp and mould have moved to the top of the social housing agenda following regulatory scrutiny and tighter enforcement around living standards. The guide aims to align building professionals, asset managers, and maintenance teams, establishing consistent protocols for managing moisture dynamics within existing housing stock.

By combining building science with housing management practices, the guide establishes clear procedures for property inspections, ventilation assessments, and long-term remediation rather than short-term surface fixes.

What does this mean for a UK tradesperson or DIYer actually buying this kit — does it change what they should pay, buy, or watch out for?

For sub-contractors, sole traders, and maintenance specialists working with local authorities or housing associations, this guidance signals a shift toward higher specifications for ventilation, insulation, and moisture control products. Tradespeople should expect procurement teams to look beyond quick surface treatments. Expect higher demand for continuous mechanical extract ventilation (MEV) units, positive input ventilation (PIV) systems, high-performance anti-mould primers, and specialized breathable damp-proofing mortars. When quoting for social housing repairs or private landlord maintenance, specifying proven, compliant products from trade counters like Screwfix or Toolstation rather than standard cosmetic paints will help secure approval from housing surveyors.

Practical Integration

Trades carrying out retrofit or maintenance work should review how their current repair methods align with the new guidance. Focusing on root-cause diagnosis, such as identifying cold bridging and inadequate extract rates, will be critical for compliance on future social housing maintenance contracts.
