Environment Agency flood zone data shows very low flood risk for RG28 7AS in Whitchurch (RG28). EA NaFRA2 data shows no properties at flood 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. For a specific property, a conveyancing search will confirm the exact flood zone position.

What is the heat risk in RG28 7AS?

Heat risk at RG28 7AS is rated Medium, reflecting Met Office UKCP18 climate projections (50th percentile) for this area, averaged over the 2021-2040 period under the RCP8.5 high emissions scenario. These are probabilistic projections - the 50th percentile is the central estimate within RCP8.5; the full range of modelled outcomes is wide and lower emissions scenarios would produce lower figures. Higher summer temperatures increase cooling energy costs, affect comfort in poorly insulated or south-facing properties, and can accelerate shrinkage in clay soils beneath foundations. Properties built before 1980 without cavity wall insulation are typically most affected.

How is the air quality in RG28 7AS?

Air quality at RG28 7AS 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 RG28 7AS?

British Geological Survey data classes the underlying soil at RG28 7AS as River Terrace Sand/Gravel, 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 RG28 7AS 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 Basingstoke and Deane and is updated as new official datasets are published.
