In short: Two 5G Innovation Region programmes in Glasgow and Greater Manchester have deployed environmental sensors in social housing to detect damp, mould, and heating problems before they become health hazards. Glasgow also deployed 515 smart speakers and 100 fall detectors, while Manchester combined damp monitoring with connected care services. The work was shortlisted for TEC awards.
Key Takeaways
- Proactive detection replaces reactive complaints — IoT sensors identify rising humidity and temperature anomalies before visible mould appears, enabling early intervention
- Health and housing data can be combined — Glasgow's deployment of smart speakers and fall detectors alongside environmental sensors creates an integrated picture of resident wellbeing
- The approach is scalable across housing stock — sensor costs have fallen to the point where monitoring every social housing unit is economically viable
In a nutshell

The Scale of the Problem
Damp and mould in UK social housing is not a niche issue — it is a systemic one. Following the tragic death of Awaab Ishak in Rochdale in 2020, caused by prolonged exposure to mould in his family's housing association flat, the problem received sustained national attention. Awaab's Law provisions in the Social Housing (Regulation) Act 2023 placed new legal obligations on social landlords to investigate and resolve damp and mould hazards within specified timeframes, which fundamentally changed the regulatory landscape.
The challenge for housing providers, however, is detection. Many problems develop behind furniture, inside wardrobes, or in poorly ventilated spaces where they are not immediately visible. By the time a tenant reports the issue, mould may have been growing for months. Vulnerable tenants — elderly residents, those with disabilities, or those for whom English is not a first language — may not report problems at all, and we have seen this pattern repeatedly across the sector.
Glasgow: Environmental Monitoring Plus Connected Care
Glasgow City Council's 5G Innovation Region programme deployed environmental sensors alongside connected care technology in social housing. The sensors monitor temperature, humidity, and air quality continuously, transmitting readings over 5G to a central analytics platform; when humidity rises above thresholds or temperature patterns suggest inadequate heating, the system alerts housing officers before mould becomes visible.
Alongside the environmental sensors, Glasgow deployed 515 smart speakers across social housing and supported living properties, plus 100 fall detectors across health and social care partnerships. Rather than treating housing conditions and resident health as separate domains — which is how most local authorities still organise their services — the programme creates a single connected picture. A property where humidity is rising, heating is intermittent, and a resident has reduced mobility is a property that needs intervention, and the integrated system makes that visible to the people who can act on it. Notably, this integration of housing and health data is straightforward technically but challenging organisationally, requiring cooperation across departments that have historically operated in silos.
Greater Manchester: Damp Sensors and Connected Care
Greater Manchester Combined Authority's 5GIR programme focused on damp and mould sensors monitoring surface temperature, ambient humidity, and dew point to flag properties at risk. The connected care element provides vulnerable residents with devices that monitor health indicators and enable direct communication with care providers — addressing a common pattern where residents living in damp conditions experience respiratory problems, but housing and health systems fail to connect those facts until the situation is severe.
Manchester's programme was shortlisted for TEC (Technology Enabled Care) awards, which recognises the quality of the approach.
Why 5G Matters Here
Individual sensors generate small amounts of data, but at scale — thousands of properties, multiple sensor types per dwelling, reporting continuously — the aggregate volumes become significant. 5G's ability to support massive numbers of IoT devices per square kilometre makes it practical to instrument entire housing estates rather than monitoring a sample, which is an important distinction. The low latency also matters: fall detection alerts need to arrive within seconds, and the analytics platform needs near-real-time feeds to generate timely interventions.
The trade-off is that 5G coverage in many social housing areas remains patchy at the time of writing, and some deployments may need to operate over 4G or even LoRaWAN for the sensor layer whilst reserving 5G for the higher-bandwidth connected care applications. We believe this is a pragmatic compromise rather than a fundamental limitation.
From Trial to Standard Practice
The legal obligations created by Awaab's Law mean that every social landlord in England now needs a strategy for proactive damp and mould detection. The Glasgow and Manchester programmes demonstrate that the technology works, the costs are manageable, and the integration with existing housing management and care systems is practical.
The question is therefore no longer whether to deploy environmental monitoring in social housing, but how quickly it can be rolled out across the millions of properties that need it — and whether the organisational changes required to act on the data can keep pace with the technology.
