How is the air quality in PR5 0AW?

Air quality at PR5 0AW 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.

Is subsidence a risk at PR5 0AW?

British Geological Survey data classes the underlying soil at PR5 0AW as Glacial Till, with shrink-swell hazard rated improbable (subsidence risk band: Low). A structural survey is the reliable way to assess ground conditions for a specific property.

Where does this data come from?

This LocalRisk report for PR5 0AW 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 GeoClimate subsidence mapping. Risk ratings are a screening tool, complementing - not replacing - the searches and surveys ordered as part of a property transaction. Data covers Chorley and is updated as new official datasets are published.
