Climate change hitting UK housing market, claims new study
PriceHubble and MIAC Analytics have released the results of a new study that they say reveals the extent to which climate change is impacting the UK housing market, with flooding and subsidence emerging as significant risks to property values, homeowners, insurers and lenders alike.
PriceHubble’s property-level analysis reveals that homes in the highest flood-risk category can sell for 2–6% below the local market value, with lower-value markets and terraced houses being hit the hardest. Meanwhile, subsidence risk is growing in southern England, particularly in Essex, East of England, and Greater London, with Castle Point seeing 82% of 2024 transactions in the highest risk category.
“These are not abstract risks anymore. Localised analysis shows that some areas are already experiencing concentrated exposure that national averages simply mask,” said Mark Cunningham, managing director of PriceHubble UK.
Comparing property values with rebuild costs reveals a stark imbalance: in lower-value flood-prone markets, rebuilding a home could cost up to 56% more than the property’s market price. Subsidence, although slower-moving, threatens long-term property resilience, particularly in areas with clay-rich soils affected by heat and drought.
MIAC Analytics’ modelling of a £330 million lifetime mortgage portfolio under various climate scenarios shows that integrating micro-level climate data increases projected losses nearly sevenfold under a “No Additional Action” scenario. In London, property values could fall by 30.9% when micro-level risks are considered, compared with modest declines in macro-only scenarios. Across all regions, incorporating property-specific risk reduced projected values by an average of 21.6%.
“As climate risk intensifies, institutions can no longer rely on coarse assumptions or regional averages. Integrating granular climate analytics into valuation and portfolio modelling is now essential for understanding the true exposure,” said Darrel Welch, managing director of MIAC Analytics.
The study highlights the need for insurers, lenders and policymakers to treat climate risk as an immediate and material threat. Without property-level data, institutions risk underestimating losses, mispricing risk and overlooking emerging hotspots of extreme exposure.
According to the companies climate risk is already reshaping the UK housing market. Institutions that adopt granular climate analytics today will be far better positioned to safeguard customers, strengthen portfolios and ensure market stability as climate pressures accelerate.
