Lambeth, Brockwell Park (SE24)
SE24 0AR in Brockwell Park (SE24) has a High flood risk - EA NaFRA2 data records 1 property at high flood risk. 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 9.3 μg/m³, above the WHO annual guideline of 5 μg/m³ (Defra UK-AIR). Ground conditions are High risk, with Prequaternary Marine/Estuarine Clay/Silt geology; shrink-swell risk is classed as probable (BGS GeoSure).
Flood risk at SE24 0AR is rated High, based on Environment Agency NaFRA2 modelling.
Environment Agency flood zone data places SE24 0AR in the high flood risk band. EA NaFRA2 data shows 1 at high 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.
Heat risk at SE24 0AR 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 SE24 0AR 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 SE24 0AR as Prequaternary Marine/Estuarine Clay/Silt, 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 SE24 0AR 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 Lambeth and is updated as new official datasets are published.
Lambeth has a dense inner-London riverside setting along the Thames with extensive hard surfacing and mixed development and experiences cool, wet winters and warm summers, shaped by urban density and estuarine influence.
Practical check: With 1 property 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 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 prequaternary marine/estuarine clay/silt 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 SE24 0AA is at localrisk.co.uk/postcode/SE240AA, and you can compare SE24 0AR side by side with any UK postcode at localrisk.co.uk/compare.
