Bloomberg and ValueSpace Map London Subsidence Acceleration

A new Bloomberg report highlights the intensifying impact of subsidence on London properties. “Londoners face a dangerous acceleration of subsidence risk as record temperatures, fuelled by climate change, destabilise the clay foundations on which most of the UK capital’s homes are built.”

• By 2030, projections indicate that over one million London properties will be at risk of subsidence.

• Association of British Insurers estimates that insurance claims tied to damage done by subsidence hit a record in 2025.

ValueSpace provided Bloomberg with an up-to-date exposure map to illustrate the subsidence-related ground movement in London. The satellite-based analysis shows that, over recent years, extreme weather conditions have contributed to destabilising the foundations on which London’s properties sit.

Following the hot weather in 2022 and a surge in subsidence, a particularly wet winter in early 2024 drove ground levels up in parts of Greater London, just before the severe dry spell of 2025.

This type of physical climate risk can quietly erode property values by 20%, drive insurance claims to record highs, and take years to remediate.

Why this matters for Financial Institutions, Asset Owners and Insurers:

Subsidence directly impacts mortgage books, insurance losses, and real-asset valuations, but remains difficult to assess using conventional hazard maps.

ValueSpace provides a near real-time, area or city-level subsidence exposure mapping - offering a detailed overview of subsidence hotspots - with the functionality to zoom in for an in-depth understanding of movement risks on a property level.

With changing weather patterns and increasingly frequent surges in subsidence, understanding the hotspots of ground movement has become essential.
