MK45 3AG - Flood, Heat, Air & Subsidence Risk - Wixams

Bedford, Wixams

Flood: MediumHeat: MediumAir quality: MediumGround: Medium

MK45 3AG in Wixams has a Medium flood risk - EA NaFRA2 data records 1 property in a flood risk zone. Heat risk is Medium, with a median (50th percentile) of 33 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 7.1 μg/m³, above the WHO annual guideline of 5 μg/m³ (Defra UK-AIR). Ground conditions are Medium risk, with Claystone/Mudstone geology; shrink-swell risk is classed as possible (BGS GeoSure).

National comparison

  • Air pollution: more polluted than 64% of councils
  • Heat risk: hotter than 81% of councils
  • Subsidence risk: higher risk than 87% of postcodes
  • Green space access: better green access than 70% of English postcodes

Flood risk at MK45 3AG is rated Medium, based on Environment Agency NaFRA2 modelling.

Heat risk at MK45 3AG 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 MK45 3AG 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.

BGS GeoSure data classes the underlying soil at MK45 3AG as Claystone/Mudstone, with shrink-swell hazard rated possible (subsidence risk band: Medium). 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 MK45 3AG 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 Bedford and is updated as new official datasets are published.

Bedford has an inland town setting surrounded by low-lying countryside and experiences cool, wet winters and warm summers, with conditions shaped by river floodplains. Flood risk is most relevant along the River Great Ouse, where prolonged rainfall affects low-lying areas in and around Bedford town.

Environment Agency flood zone data places MK45 3AG in the medium flood risk band. EA NaFRA2 data shows 1 at medium 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. Individual properties within MK45 3AG can differ - a formal flood risk search is recommended before any property transaction.

Practical check: EA data flags 1 property at flood risk here - check whether the property is among them by comparing its position to the flood zone boundary. 33 hot days are projected (UKCP18 50th percentile, 2021-2040 average under RCP8.5) - check which rooms face south or west and whether the property has cross-ventilation or 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 claystone/mudstone 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.
