Climate risk summary for CR3 0AD

CR3 0AD in Farleigh (CR3) has a Medium flood risk - EA NaFRA2 data records 1 property in a flood risk zone. Heat risk is Medium, with a median (50th percentile) of 30 days above 25°C per year, averaged over the 2021-2040 period under the RCP8.5 high emissions scenario (Met Office UKCP18). Air quality is Medium at PM2.5 7.2 μg/m³, above the WHO annual guideline of 5 μg/m³ (Defra UK-AIR). Ground conditions are Low risk, with Chalk geology; shrink-swell risk is classed as improbable (BGS GeoSure).

How does CR3 0AD compare with the rest of the UK?

  • Air pollution: more polluted than 55% of councils
  • Heat risk: hotter than 74% of councils
  • Subsidence risk: lower risk than 58% of postcodes
  • Green space access: better green access than 81% of English postcodes

What is the flood risk in CR3 0AD?

Flood risk at CR3 0AD is rated Medium, based on Environment Agency NaFRA2 modelling.

Environment Agency flood zone data places CR3 0AD in the medium flood risk band. EA NaFRA2 data shows 1 at medium risk in this postcode. Groundwater flood risk is classed as possible. The band reflects the highest flood risk within the postcode; some properties within this postcode may face little or no direct flood risk. Individual properties within CR3 0AD can differ - a formal flood risk search is recommended before any property transaction.

What is the heat risk in CR3 0AD?

Heat risk at CR3 0AD is rated Medium, reflecting Met Office UKCP18 climate projections (50th percentile) for this area, averaged over the 2021-2040 period under the RCP8.5 high emissions scenario. These are probabilistic projections - the 50th percentile is the central estimate within RCP8.5; the full range of modelled outcomes is wide and lower emissions scenarios would produce lower figures. Higher summer temperatures increase cooling energy costs, affect comfort in poorly insulated or south-facing properties, and can accelerate shrinkage in clay soils beneath foundations. Properties built before 1980 without cavity wall insulation are typically most affected.

How is the air quality in CR3 0AD?

Air quality at CR3 0AD is rated Medium, based on Defra UK-AIR annual mean PM2.5 data. Fine particulate matter (PM2.5) comes primarily from road traffic, industry, and domestic burning. Long-term exposure above the WHO guideline of 5 µg/m³ is linked to respiratory and cardiovascular health risks. Buyers and renters in higher air quality risk areas may wish to consider whether the property is near busy roads or industrial sources.

Is subsidence a risk at CR3 0AD?

BGS GeoSure data classes the underlying soil at CR3 0AD as Chalk, with shrink-swell hazard rated improbable (subsidence risk band: Low). Soil type and shrink-swell behaviour drive subsidence claims following dry summers; recent ABI data shows insurer payouts rose sharply after the 2022 and 2025 hot summers. A structural survey is the reliable way to assess ground risk for a specific property.

Where does this data come from?

This LocalRisk report for CR3 0AD draws on four official UK open data sources: Environment Agency NaFRA2 flood modelling, Met Office UKCP18 climate projections, Defra UK-AIR PM2.5 monitoring, and British Geological Survey GeoSure subsidence mapping. Risk ratings are a screening tool, complementing - not replacing - the searches and surveys ordered as part of a property transaction. Data covers Tandridge and is updated as new official datasets are published.

About the Tandridge area

Tandridge has a largely rural and commuter-belt setting straddling the chalk of the North Downs and a greensand ridge to the south, with woodland and river valleys, and experiences cool, wet winters and warm summers, shaped by elevation and free-draining geology.

What should buyers and renters check in CR3 0AD?

Practical check: EA data flags 1 property at flood risk here - check whether the property is among them by comparing its position to the flood zone boundary. 30 hot days are projected (UKCP18 50th percentile, 2021-2040 average under RCP8.5) - check which rooms face south or west and whether the property has cross-ventilation or external shading. With PM2.5 above WHO guidelines here, check which bedrooms face busy roads and how fresh air is drawn into living spaces. These are postcode-level indicators - conditions vary between individual properties.

Climate risk can change street by street, so it is worth checking neighbouring postcodes too. The full risk report for CR3 0AA is at localrisk.co.uk/postcode/CR30AA, and you can compare CR3 0AD side by side with any UK postcode at localrisk.co.uk/compare.
