Heat risk is Medium, with a median (50th percentile) of 28 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 6.8 μg/m³, above the WHO annual guideline of 5 μg/m³ (Defra UK-AIR). Ground conditions are Low risk, with Riverine Clay And Floodplain Sands And Gravel geology; shrink-swell risk is classed as improbable (BGS GeoSure).

  • Green space access: better green access than 53% of English postcodes

What is the flood risk in TN23 7TP?

Flood risk at TN23 7TP is rated High, based on Environment Agency NaFRA2 modelling.

Environment Agency flood zone data places TN23 7TP in the high flood risk band. EA NaFRA2 data shows 16 at high risk, 3 at medium risk in this postcode. The band reflects the highest flood risk within the postcode; some properties within this postcode may face little or no direct flood risk. A formal flood risk search and review of buildings insurance availability is recommended before any property transaction in this area.

What is the heat risk in TN23 7TP?

Heat risk at TN23 7TP 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 TN23 7TP?

Air quality at TN23 7TP 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 TN23 7TP?

BGS GeoSure data classes the underlying soil at TN23 7TP as Riverine Clay And Floodplain Sands And Gravel, 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 TN23 7TP 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 Ashford and is updated as new official datasets are published.

About the Ashford area

Ashford has an inland setting with rapidly expanding town development and experiences cool, wet winters and warm summers, influenced by low-lying land and major transport corridors.

What should buyers and renters check in TN23 7TP?

Practical check: With 16 properties at high flood risk here, ask about past flooding events, check the entrance threshold height relative to road level, and review buildings insurance terms. With 28 hot days projected (UKCP18 50th percentile, 2021-2040 average under RCP8.5), note which bedrooms face west (hottest in evening) and whether windows allow through-ventilation. These are postcode-level indicators - conditions vary between individual properties.
