Flood risk at FY5 1AJ is rated Medium, based on Environment Agency NaFRA2 modelling.

Air quality at FY5 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 FY5 1AJ as Quaternary Marine/Estuarine Clay/Silt, 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 FY5 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 Wyre and is updated as new official datasets are published.

Wyre has a low-lying coastal and rural setting with estuaries, flat farmland and small towns and experiences cool, wet winters and mild summers, shaped by Irish Sea exposure and limited elevation.
