Flood risk at DN11 9LX is rated High, based on Environment Agency NaFRA2 modelling.

Air quality at DN11 9LX 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.

BGS GeoSure data classes the underlying soil at DN11 9LX as Sandstone, 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.

This LocalRisk report for DN11 9LX 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 Doncaster and is updated as new official datasets are published.

Doncaster has a low-lying inland setting with river floodplains and former industrial land and experiences cool, wet winters and warm summers, influenced by flat terrain and extensive drainage networks.

Environment Agency flood zone data places DN11 9LX in the high flood risk band. EA NaFRA2 data shows 7 at high risk, 2 at medium risk, 9 at low 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: With 7 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 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 PM2.5 above WHO guidelines here, check which bedrooms face busy roads and how fresh air is drawn into living spaces. These are postcode-level indicators - conditions vary between individual properties.
