Urban heat data for better decisions
We provide high-resolution urban heat data to local authorities, public sector bodies and businesses. The Urban Heat Index helps your organisation understand, map, and respond to urban heat risk.

How we can help
Mapping evidence that turns heat risk into action.
Client-ready datasets
Structured outputs to help with planning, reporting and decision making, with a focus on clear interpretation rather than raw data alone.
Geographic boundary aggregation
Heat data structured and summarised by specific administrative zones (such as local authority districts, wards, or LSOAs) for seamless integration into your existing GIS platforms.
Time-series heat datasets
Historical and seasonal data that allows you to track temperature variations over time, compare different years, and accurately monitor long-term environmental trends.
Why is heat data important
Understanding urban heat risk
What is the Urban Heat Island effect?
Built-up areas absorb and retain more heat than nearby green or rural areas. This creates higher temperatures at street level, bringing risks for health, buildings, and transport.
The Climate Reality
Hot weather is becoming more common across the globe. Local authorities need better local evidence to identify heat risk, target action and make places safer during heatwaves.
Our Clients
Working with Local Authorities
We are working with a range of local authorities to help them better understand and mitigate urban heat risks.
“Environmental justice is at the heart of H&F’s approach. This data will be used alongside residents’ lived experiences and local knowledge to ensure that interventions are both evidence-based and community-informed.”
— Charlie Bone, Natural Environment Lead, London Borough of Hammersmith & Fulham
“This data set helps us to understand where heat is affecting our communities the most and allows us to better plan and mitigate for these impacts, particularly for more vulnerable people in our communities such as older people, young children, and those with existing health conditions.”
— Charlotte Ball, Public Health Manager (Healthy Places), Bedford Borough Council
