How are Environmental Searches for Conveyancing Changing

The new Law Society Practice Note will instruct conveyancers on how to conduct climate change environmental searches during property transactions. Here’s how these searches may be conducted and what they will include:

1. Climate Risk Environmental Searches

Conveyancers will be expected to obtain climate change risk reports from specialist environmental data providers. In addition to risk areas already searched, flood, contaminated land and subsidence, these reports will assess new areas that include:

• Heat Stress: Risk of overheating in homes and urban heat island effects.
• Water Stress & Drought: Future water availability, subsidence risks, and local water restrictions.
• Wildfire Risk: Proximity to fire-prone areas and likelihood of property damage.

2. Key Data Sources Used

• Met Office Climate Projections (UKCP18): Predicts future climate risks at different warming scenarios.
• British Geological Survey (BGS): Identifies ground conditions and subsidence risks.
• Proprietary and Open-Source Data: Maps land use changes, vegetation coverage, land-surface and air temperatures, fire-prone areas, historic trends and events, specific risk outputs.
• Local Authority & Environment Agency Data: Includes planning restrictions, conservation areas, and fire service resources.

3. How the Search Results Impact Transactions

Once obtained, the search results may affect the transaction in several ways:

• Buyer & Lender Awareness: If a property is at higher risk, buyers may consider what mitigation activities may need to be considered and any associated costs; evidence could lead to a revised offer.
• Insurance Considerations: Higher-risk properties could see increased premiums, affecting affordability.
• Legal Advice & Contractual Protections: Conveyancers may advise including climate risk mitigation clauses in contracts.

Most search results will report acceptable current levels of risk – with the outputs providing appropriate sources of guidance and information; future projections will need to be considered as we experience warmer, drier climate conditions.

4. Potential Mitigation Measures for High-Risk Properties

For properties flagged as vulnerable, conveyancers may advise clients on mitigation options such as:

• Installing heat-resistant materials and cooling systems in heat-prone areas.
• Using drought-resistant landscaping to reduce water dependency.
• Creating defensible space around properties in wildfire-prone locations.

5. Futureproofing the Market

The introduction of climate risk searches signals a shift in property due diligence, ensuring buyers are aware of the long-term viability of their investment with forward-looking projections. This will also likely drive better resilience measures in new developments.
