Sunderland, Houghton-le-Spring (DH4)
Heat risk is Lower, with a median (50th percentile) of 5 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 Low at PM2.5 6.0 μg/m³, above the WHO annual guideline of 5 μg/m³ (Defra UK-AIR). Ground conditions are Low risk, with Glaciolacustrine geology; shrink-swell risk is classed as improbable (BGS GeoClimate).
An official flood-risk band is not available for DH4 4AH in the current dataset releases used by LocalRisk. This is a data-coverage gap rather than a low-risk rating. For a property-level reading, the Environment Agency's Check Your Long-Term Flood Risk service covers every address in England.
Air quality at DH4 4AH 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 DH4 4AH as Glaciolacustrine, 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 DH4 4AH 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 Sunderland and is updated as new official datasets are published.
Sunderland has a coastal and urban setting along the River Wear with dense development, former industrial land and exposed North Sea frontage and experiences cool, wet winters and mild summers, influenced by maritime exposure.
Climate risk can change street by street, so it is worth checking neighbouring postcodes too. The full risk report for DH4 4AB is at localrisk.co.uk/postcode/DH44AB, and you can compare DH4 4AH side by side with any UK postcode at localrisk.co.uk/compare.
