Aico and Selwood Housing: case study
Case study by Aico #SocialCareTransformation
The challenge
Selwood Housing manages over 7,000 homes. We have been working with them since 2023 on a shift away from reactive maintenance toward predictive, data-driven decision-making across their portfolio. The introduction of Awaab’s Law has significantly increased the need for timely investigation and resolution of hazards such as damp and mould, and the wider question has been how connected technology can support compliance while also giving residents themselves the tools to understand and influence the conditions in their homes.
What we did
We deployed Aico’s HomeLINK technology, a system of Environmental Sensors, Gateways and cloud-based analytics that provide continuous visibility into indoor environmental conditions. The sensors monitor temperature, humidity and CO₂, transmitting data in real time to a central platform. What began as a pilot has scaled to more than 250 actively monitored properties, supported by over 2,000 connected IoT devices including environmental sensors, fire alarms and carbon monoxide alarms, integrated into a unified system via HomeLINK Gateways.
The system feeds analytics dashboards used by housing teams, enabling automated reporting, trend analysis and risk flagging, reducing reliance on manual inspections while increasing the accuracy and frequency of monitoring. Rising humidity can be identified before visible mould appears, allowing intervention at a much earlier stage. After repair work, sensors continue to monitor conditions to confirm whether the intervention has been successful or further action is required: a closed-loop feedback system essential for meeting regulatory standards while ensuring long-term effectiveness.
The HomeLINK Resident App extends the system to tenants, translating sensor data into clear visual indicators and notifications. Healthy Home Indicators show whether conditions are within healthy ranges. Tailored Recommendations advise on ventilation or heating. Damp and Mould Alerts give proactive notifications with practical guidance. Device Maintenance Reminders prompt testing of fire and CO alarms. Trusted Access allows residents to securely share app access with family or carers. When a resident receives a notification, the same data is visible to Selwood’s Damp and Mould Team, enabling a coordinated response.
The outcome
The deployment has shifted Selwood’s compliance posture and operational model. Surveyors now rely on data insights to prioritise cases, and automated reports highlight properties at higher risk. Weekly data outputs provide actionable intelligence, enabling faster response times and more efficient resource allocation. The resident app has driven behaviour change at the household level: a notification about rising humidity may prompt a resident to open a window or improve ventilation, and over time these small actions contribute to improved indoor air quality and reduced incidence of damp and mould. Shared visibility between residents and housing teams reduces communication gaps and builds trust, with teams able to prioritise interventions based on data-driven risk assessments rather than reactive callouts. The model is scalable, with plans to install additional sensors in further properties as adoption continues.
