East Riding of Yorkshire, Hornsea (HU18)
HU18 1QB in Hornsea (HU18) has a High flood risk - EA NaFRA2 data records 13 properties at high flood risk. Heat risk is Lower, with a median (50th percentile) of 16 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 Medium at PM2.5 6.4 μg/m³, above the WHO annual guideline of 5 μg/m³ (Defra UK-AIR). Ground conditions are Low risk, with Quaternary Marine/Estuarine Sand geology; shrink-swell risk is classed as improbable (BGS GeoClimate).
Flood risk at HU18 1QB is rated High, based on Environment Agency NaFRA2 modelling.
Environment Agency flood zone data places HU18 1QB in the high flood risk band. EA NaFRA2 data shows 13 at high risk, 1 at medium risk, 5 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.
Air quality at HU18 1QB 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.
British Geological Survey data classes the underlying soil at HU18 1QB as Quaternary Marine/Estuarine Sand, 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.
The nearest projected coastal erosion zone to HU18 1QB is 185 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. Check the Shoreline Management Plan for this stretch for the projections that apply to a specific property.
This LocalRisk report for HU18 1QB 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 East Riding of Yorkshire and is updated as new official datasets are published.
East Riding of Yorkshire has a varied setting spanning chalk uplands, low-lying plains and a long coastline and experiences cool, wet winters and warm summers, shaped by elevation and maritime influence.
