How is the air quality in YO1 6DB?

Air quality at YO1 6DB is rated Low, 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 YO1 6DB?

BGS GeoSure data classes the underlying soil at YO1 6DB as Glacial Till, 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 YO1 6DB 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 York and is updated as new official datasets are published.

What should buyers and renters check in YO1 6DB?

Practical check: With 36 properties 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 21 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. These are postcode-level indicators - conditions vary between individual properties.
