Climate risk summary for CT5 1ND

CT5 1ND in Thurston Park (CT5) has a High flood risk - EA NaFRA2 data records 38 properties at high flood risk. Heat risk is Lower, with a median (50th percentile) of 25 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 6.7 μg/m³, above the WHO annual guideline of 5 μg/m³ (Defra UK-AIR). Ground conditions are High risk, with Prequaternary Marine/Estuarine Clay/Silt geology; shrink-swell risk is classed as probable (BGS GeoSure).

How does CT5 1ND compare with the rest of the UK?

  • Air pollution: cleaner than 59% of councils
  • Heat risk: hotter than 58% of councils
  • Subsidence risk: higher risk than 95% of postcodes
  • Green space access: better green access than 79% of English postcodes

What is the flood risk in CT5 1ND?

Flood risk at CT5 1ND is rated High, based on Environment Agency NaFRA2 modelling.

Environment Agency flood zone data places CT5 1ND in the high flood risk band. EA NaFRA2 data shows 38 at high 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.

How is the air quality in CT5 1ND?

Air quality at CT5 1ND 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 CT5 1ND?

BGS GeoSure data classes the underlying soil at CT5 1ND as Prequaternary Marine/Estuarine Clay/Silt, with shrink-swell hazard rated probable (subsidence risk band: High). 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.

Is CT5 1ND at risk of coastal erosion?

The nearest projected coastal erosion zone to CT5 1ND is 180 m away (Erosion projected by 2055 (no climate change uplift) - SMP policy: Hold The Line mapping) and the postcode is in the very high coastal erosion risk band. Coastal erosion risk varies along the shoreline depending on local geology, sea defences and Shoreline Management Plan policy. Check the Shoreline Management Plan for this stretch for the projections that apply to a specific property.

Where does this data come from?

This LocalRisk report for CT5 1ND 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 Canterbury and is updated as new official datasets are published.

About the Canterbury area

Canterbury has a mixed urban and rural setting across chalk downs and river valleys and experiences cool, wet winters and warm summers, shaped by coastal influence and local topography.

What should buyers and renters check in CT5 1ND?

Practical check: EA flags 38 properties at flood risk here, near the coast - compare the floor level to the highest recorded tide line and check for flood resilience measures. With 25 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. With prequaternary marine/estuarine clay/silt geology here, look for signs of ground movement - diagonal cracks above windows, sticking doors, and gaps between walls and extensions. The nearest projected erosion zone is 180m away - check the Shoreline Management Plan policy for this stretch and whether the property is within 100 years of the erosion line. 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 CT5 1AB is at localrisk.co.uk/postcode/CT51AB, and you can compare CT5 1ND side by side with any UK postcode at localrisk.co.uk/compare.
