Dorset, Redlands
DT3 6PU in Redlands has a High flood risk - EA NaFRA2 data records 26 properties at high flood risk. Heat risk is Lower, with a median (50th percentile) of 23 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 Low at PM2.5 5.5 μg/m³, above the WHO annual guideline of 5 μg/m³ (Defra UK-AIR). Ground conditions are Medium risk, with Riverine Clay And Floodplain Sands And Gravel geology; shrink-swell risk is classed as possible (BGS GeoSure).
National comparison
Flood risk at DT3 6PU is rated High, based on Environment Agency NaFRA2 modelling.
Air quality at DT3 6PU 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 DT3 6PU as Riverine Clay And Floodplain Sands And Gravel, with shrink-swell hazard rated possible (subsidence risk band: Medium). 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 DT3 6PU is 60 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 DT3 6PU 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 Dorset and is updated as new official datasets are published.
Dorset has a mixed coastal and rural setting with chalk downland, river valleys and low-lying plains and experiences cool, wet winters and warm summers, shaped by maritime influence and varied topography.
Environment Agency flood zone data places DT3 6PU in the high flood risk band. EA NaFRA2 data shows 26 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 26 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 23 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 riverine clay and floodplain sands and gravel 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 60m 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.
