Natural Resources Wales flood zone data places CH1 6BS in the medium flood risk band. The band reflects the highest flood risk within the postcode; some properties within this postcode may face little or no direct flood risk. Individual properties within CH1 6BS can differ - a formal flood risk search is recommended before any property transaction.
Air quality at CH1 6BS 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.
British Geological Survey data classes the underlying soil at CH1 6BS as Quaternary Marine/Estuarine Sand And Silt, 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.
This LocalRisk report for CH1 6BS draws on four official UK open data sources: Natural Resources Wales flood mapping, 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 Flintshire and is updated as new official datasets are published.
