Hammersmith and Fulham, Parsons Green (SW6)
SW6 1AE in Parsons Green (SW6) has a Very low flood risk - EA NaFRA2 data records no properties in a flood risk zone in this postcode. Heat risk is Higher, with a median (50th percentile) of 40 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 High at PM2.5 9.1 μg/m³, above the WHO annual guideline of 5 μg/m³ (Defra UK-AIR). Ground conditions are High risk, with River Terrace Sand/Gravel geology; shrink-swell risk is classed as probable (BGS GeoSure).
Flood risk at SW6 1AE is rated Very Low, based on Environment Agency NaFRA2 modelling.
Environment Agency flood zone data shows very low flood risk for SW6 1AE in Parsons Green (SW6). 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.
Heat risk at SW6 1AE is rated Higher, 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.
Air quality at SW6 1AE is rated High, 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.
BGS GeoSure data classes the underlying soil at SW6 1AE as River Terrace Sand/Gravel, with shrink-swell hazard rated probable (subsidence risk band: High). 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.
This LocalRisk report for SW6 1AE 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 Hammersmith and Fulham and is updated as new official datasets are published.
Hammersmith and Fulham has a dense riverside west London setting along the Thames and experiences cool, wet winters and warm summers, influenced by urban density and estuarine conditions.
Practical check: With 40 hot days projected (UKCP18 50th percentile, 2021-2040 average under RCP8.5), overheating is a real concern - check which rooms face south or west, whether windows allow cross-ventilation, and if there is any external shading. With PM2.5 above WHO guidelines here, check which bedrooms face busy roads and how fresh air is drawn into living spaces. With river terrace sand/gravel geology here, look for signs of ground movement - diagonal cracks above windows, sticking doors, and gaps between walls and extensions. These are postcode-level indicators - conditions vary between individual properties.
Climate risk can change street by street, so it is worth checking neighbouring postcodes too. The full risk report for SW6 1AA is at localrisk.co.uk/postcode/SW61AA, and you can compare SW6 1AE side by side with any UK postcode at localrisk.co.uk/compare.
