Funded by the UK Space Agency. Welcoming early partners.
Home Horizon combines Earth observation satellite data with open data about buildings to rank every home by relative exposure to overheating. Plan remediation before summer, and know where to look first when a heatwave is on the way.
Relative risk. Illustrative scene, not real homes.
Home Horizon is funded by the UK Space Agency through its Commercial Climate Services Call 4. Developed by Quantum Risk Solutions Ltd, a technology company based in Wakefield, West Yorkshire.
Summer heat is a health risk. The UK Health Security Agency's interim estimate is 2,877 heat-associated deaths in England across two heat episodes in May and June 2026. Read the UKHSA report
From this date, Awaab's Law extends to excess heat in social housing in England. Every report of a significant or emergency hazard starts a fixed clock.
A hot spell can bring many reports at once, each with its own clock. And overheating is hard to see: a home inspected in January tells you little about its bedrooms in July.
One ranking of your whole stock, put to work before summer and again when the heat arrives.
See which homes are most exposed to overheating across your whole stock, so remediation and investment reach them first.
Where retrofit follows PAS 2035:2023, the retrofit design must include measures to reduce or limit overheating, recorded by the Retrofit Designer, with CIBSE TM59 among the named methods. Home Horizon shows where that attention matters most.
When a UKHSA Heat-Health Alert is issued, or local forecasts show a hot spell coming, Home Horizon will point your teams to the most exposed homes in the area, so checks, advice and contact reach them before the hottest days.
Earth observation satellites show which streets and surroundings run hotter on clear summer days.
Open data about the buildings themselves tells apart homes on the same street.
We calibrate the ranking against indoor measurements taken in real homes.
Satellites see roofs, roads and ground, not the inside of homes. So Home Horizon ranks relative risk rather than forecasting indoor temperatures.
We decide how we'll judge the ranking before we see the results, and we publish what we find, whatever it shows. A full summer test follows in 2027.
Home Horizon is in development with UK Space Agency funding. Early partners help shape it around how landlords actually work.
A short conversation is the best place to start, with no commitment. You will hear back from Janice Thomas or Callum Wright.
