National comparison

  • Air pollution: cleaner than 82% of councils
  • Heat risk: cooler than 84% of councils
  • Subsidence risk: lower risk than 58% of postcodes
  • Green space access: better green access than 62% of English postcodes

Flood risk at TR11 4FJ is rated High, based on Environment Agency NaFRA2 modelling.

Air quality at TR11 4FJ is rated Low, 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.

The nearest projected coastal erosion zone to TR11 4FJ is 161 m away (Erosion projected by 2055 (no climate change uplift) - SMP policy: No Active Intervention 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. For properties near the coast, a specialist coastal erosion risk assessment is recommended.

This LocalRisk report for TR11 4FJ 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 Cornwall and is updated as new official datasets are published.

Cornwall has an exposed coastal and rural setting with upland moors and river valleys and experiences cool, wet winters and mild summers, shaped by Atlantic influences and varied topography.

Environment Agency flood zone data places TR11 4FJ in the high flood risk band. EA NaFRA2 data shows 44 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.

Practical check: EA flags 44 properties at flood risk here, near the coast - compare the floor level to the highest recorded tide line and check for flood resilience measures. The nearest projected erosion zone is 161m 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.
