What is it?

A follow-up evaluation report that captures learning from the 2024–25 winter deployment of IoT environmental sensors used to monitor damp and mould in social housing. It also explores boroughs’ plans for the future as the pilot project concludes. The report includes insights from 12 participating boroughs

Why was it created?

This evaluation was created as a follow-up to a preliminary evaluation conducted in late 2024. Its specific aims were to:

• Identify trends and patterns in damp and mould over the winter months.
• Understand boroughs’ future plans for using sensors.
• Assess the impact on London’s capacity to identify and manage damp and mould. It captures new insights from the winter period, when damp and mould issues are typically more acute, and explores boroughs’ plans as the pilot comes to an end.

Who should use it?

This resource is particularly useful for:

• Councils looking to implement or scale IoT sensor technology to improve the quality of their housing stock and proactively manage damp and mould issues.
• Housing officers and data teams involved in managing and addressing damp and mould, particularly those seeking to integrate sensor data and develop efficient response processes.
• Local authorities interested in proactive and early identification of damp and mould risks and meeting legal obligations such as Awaab’s Law.
• Organisations and teams focused on addressing fuel poverty as a key driver of damp and mould, by integrating resident support into their response protocols.
