Climate risk summary for GL10 2AS

GL10 2AS in Newtown (GL10) has a High flood risk - EA NaFRA2 data records 3 properties at high flood risk. Heat risk is Medium, with a median (50th percentile) of 26 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 Riverine Clay And Floodplain Sands And Gravel geology; shrink-swell risk is classed as improbable (BGS GeoSure).

What is the flood risk in GL10 2AS?

Flood risk at GL10 2AS is rated High, based on Environment Agency NaFRA2 modelling.

Environment Agency flood zone data places GL10 2AS in the high flood risk band. EA NaFRA2 data shows 3 at high risk, 5 at medium risk, 17 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.

What is the heat risk in GL10 2AS?

Heat risk at GL10 2AS 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 GL10 2AS?

Air quality at GL10 2AS 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.

Is subsidence a risk at GL10 2AS?

BGS GeoSure data classes the underlying soil at GL10 2AS as Riverine Clay And Floodplain Sands And Gravel, with shrink-swell hazard rated improbable (subsidence risk band: Low). Soil type and shrink-swell behaviour drive subsidence claims following dry summers; recent ABI data shows insurer payouts rose sharply after the 2022 and 2025 hot summers. A structural survey is the reliable way to assess ground risk for a specific property.

Where does this data come from?

This LocalRisk report for GL10 2AS 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 GeoSure subsidence mapping. Risk ratings are a screening tool, complementing - not replacing - the searches and surveys ordered as part of a property transaction. Data covers Stroud and is updated as new official datasets are published.

About the Stroud area

Stroud has a mixed rural and market town setting with steep valleys, river corridors and the surrounding Cotswold escarpment and experiences cool, wet winters and mild summers, shaped by elevation and complex topography.

What should buyers and renters check in GL10 2AS?

Practical check: With 3 properties at high flood risk here, ask about past flooding events, check the entrance threshold height relative to road level, and review buildings insurance terms. With 26 hot days projected (UKCP18 50th percentile, 2021-2040 average under RCP8.5), note which bedrooms face west (hottest in evening) and whether windows allow through-ventilation. These are postcode-level indicators - conditions vary between individual properties.
