Flood risk at TD15 1AJ is rated Very Low, based on Environment Agency NaFRA2 modelling.

Air quality at TD15 1AJ 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.

BGS GeoSure data classes the underlying soil at TD15 1AJ as Glacial Till, 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.

The nearest projected coastal erosion zone to TD15 1AJ is 147 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. For properties near the coast, a specialist coastal erosion risk assessment is recommended.

This LocalRisk report for TD15 1AJ 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 Northumberland and is updated as new official datasets are published.

Northumberland has a largely rural and coastal setting with upland areas, river valleys and an extensive North Sea coastline and experiences cool, wet winters and mild summers, influenced by maritime exposure and elevation inland.

Environment Agency flood zone data shows very low flood risk for TD15 1AJ in Prior Park. EA NaFRA2 data shows no properties at flood 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. For a specific property, a conveyancing search will confirm the exact flood zone position.

Practical check: The nearest projected erosion zone is 147m 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.
