Clarion deploys Map Impact’s HeatView product to inform Climate Resilience and Adaptation

Clarion Housing Group, the UK’s largest housing association, are using Map Impact’s geospatial heat mapping product, HeatView, to support data-driven resilience across their entire portfolio.

As climate change accelerates, housing associations across the UK are facing mounting risks to their housing stock, affecting both their residents and long-term financial stability. From extreme heatwaves and flooding to infrastructure strain and rising retrofit costs, the sector must now embed climate resilience into core asset management strategies. Clarion are leading the way with their sector-leading sustainability strategy.

A groundbreaking study led by the University of East London (UEL) has revealed a dramatic and deeply concerning rise in the number of UK households reported suffering from overheating during summer months, with the figure soaring from 18% in 2011 to a staggering 80% in 2022. Many social housing properties were not designed to cope with sustained high temperatures. HeatView enables organisations to pinpoint hotspots across estates and neighbourhoods, identify clusters of high-risk properties, and target interventions such as shading, insulation upgrades, ventilation improvements, and green infrastructure.

Map Impact’s HeatView has been delivered to Clarion in partnership with ODCGIS as part of ODCGIS’ wider Property Insights initiative, which provides integrated, location-intelligent property data solutions. Embedding overheating risk analysis within a richer spatial context of authoritative mapping, asset intelligence and environmental datasets enables more precise, scalable and strategically aligned decision-making.

Becky Ritchie, Clarion’s Head of Sustainability, commented: “Without accurate, portfolio-wide data, we risk responding reactively rather than proactively managing climate exposure. Integrating tools such as Map Impact’s HeatView into our asset strategy helps us with decision-making around where to prioritise our retrofit investment, and align resilience planning with regulatory and ESG requirements. This shifts us from compliance-driven responses to a strategic, data-led approach that better supports our residents, safeguards long-term asset value, and builds climate-ready communities.”

Richard Flemmings, Map Impact’s CEO added: “At Map Impact, we developed HeatView to give real estate stakeholders and housing providers the clarity they need to move from broad climate awareness to precise, property-level action. By combining satellite-derived temperature data with detailed landscape analysis, HeatView enables organisations like Clarion to identify overheating risks across their entire portfolio, prioritise investment where it will have the greatest impact, and embed climate resilience directly into asset management and decarbonisation strategies. It’s about turning complex climate data into practical decisions that protect residents and future-proof homes.”

Rick Thompson, ODCGIS’ Business Development Lead said: “Integrating HeatView with authoritative geospatial datasets such as the Ordnance Survey’s National Geographic Database (NGD) significantly enhances the value of climate risk analysis. By combining advanced heat modelling with highly accurate, up-to-date mapping and property intelligence, housing providers gain a far richer spatial context for decision-making. This integration enables more precise identification of at-risk assets, stronger alignment with asset management systems, and a scalable foundation for wider environmental and infrastructure planning. It ensures climate resilience strategies are built on trusted, connected data rather than isolated insights.”
