Climate risk summary for B3 1BP

B3 1BP in New Town Row (B3) has a Low flood risk - EA NaFRA2 data records 32 properties in a flood risk zone. 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 Medium at PM2.5 7.9 μg/m³, above the WHO annual guideline of 5 μg/m³ (Defra UK-AIR). Ground conditions are Low risk, with Glaciofluvial Deposits geology; shrink-swell risk is classed as improbable (BGS GeoSure).

How does B3 1BP compare with the rest of the UK?

  • Air pollution: more polluted than 85% of councils
  • Heat risk: hotter than 58% of councils
  • Subsidence risk: lower risk than 58% of postcodes
  • Green space access: less green access than 95% of English postcodes

What is the flood risk in B3 1BP?

Flood risk at B3 1BP is rated Low, based on Environment Agency NaFRA2 modelling.

Environment Agency flood zone data shows low flood risk for B3 1BP in New Town Row (B3). EA NaFRA2 data shows 32 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.

What is the heat risk in B3 1BP?

Heat risk at B3 1BP 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 B3 1BP?

Air quality at B3 1BP 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 B3 1BP?

BGS GeoSure data classes the underlying soil at B3 1BP as Glaciofluvial Deposits, 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 B3 1BP 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 Birmingham and is updated as new official datasets are published.

About the Birmingham area

Birmingham has a large, dense urban setting with varied topography and experiences cool, wet winters and warm summers, shaped by built form and river corridors.

What should buyers and renters check in B3 1BP?

Practical check: EA data flags 32 properties at flood risk here - check whether the property is among them by comparing its position to the flood zone boundary. 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. With PM2.5 above WHO guidelines here, check which bedrooms face busy roads and how fresh air is drawn into living spaces. 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 B3 1AG is at localrisk.co.uk/postcode/B31AG, and you can compare B3 1BP side by side with any UK postcode at localrisk.co.uk/compare.
