Gosport, Camdentown (PO12)
PO12 1AN in Camdentown (PO12) has a Low flood risk - EA NaFRA2 data records 12 properties in a flood risk zone. Heat risk is Medium, with a median (50th percentile) of 28 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 Medium at PM2.5 6.1 μg/m³, above the WHO annual guideline of 5 μg/m³ (Defra UK-AIR). Ground conditions are Low risk, with River Terrace Sand/Gravel geology; shrink-swell risk is classed as improbable (BGS GeoClimate).
Flood risk at PO12 1AN is rated Low, based on Environment Agency NaFRA2 modelling.
Environment Agency flood zone data shows low flood risk for PO12 1AN in Camdentown (PO12). EA NaFRA2 data shows 12 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. For a specific property, a conveyancing search will confirm the exact flood zone position.
Heat risk at PO12 1AN 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.
Air quality at PO12 1AN 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.
British Geological Survey data classes the underlying soil at PO12 1AN 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.
The nearest projected coastal erosion zone to PO12 1AN is 97 m away (Erosion projected by 2055 (no climate change uplift) - SMP policy: Hold The Line mapping) and the postcode is in the very high coastal erosion risk band. Coastal erosion risk varies along the shoreline depending on local geology, sea defences and Shoreline Management Plan policy. Check the Shoreline Management Plan for this stretch for the projections that apply to a specific property.
This LocalRisk report for PO12 1AN 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 Gosport and is updated as new official datasets are published.
Gosport has a low-lying coastal and peninsular setting between Portsmouth Harbour and the Solent and experiences cool, wet winters and warm summers, influenced by maritime conditions.
Practical check: EA flags 12 properties at flood risk here, near the coast - compare the floor level to the highest recorded tide line and check for flood resilience measures. With 28 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. The nearest projected erosion zone is 97m away - check the Shoreline Management Plan policy for this stretch and whether the property is within 100 years of the erosion line. 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 PO12 1AA is at localrisk.co.uk/postcode/PO121AA, and you can compare PO12 1AN side by side with any UK postcode at localrisk.co.uk/compare.
