Heat risk is Lower, with a median (50th percentile) of 2 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 Low at PM2.5 3.1 μg/m³, within the WHO annual guideline of 5 μg/m³ (Defra UK-AIR).

National comparison

  • Air pollution: cleaner than 95% of councils
  • Heat risk: cooler than 95% of councils
  • Subsidence risk: lower risk than 58% of postcodes

Flood risk at HS8 5JL is rated Higher, based on SEPA flood mapping.

Air quality at HS8 5JL 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.

The nearest projected coastal erosion zone to HS8 5JL is 117 m away (NatureScot Dynamic Coast - eroded area by 2050 (high emissions) 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. For properties near the coast, a specialist coastal erosion risk assessment is recommended.

This LocalRisk report for HS8 5JL draws on four official UK open data sources: SEPA flood mapping, 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 Na h-Eileanan Siar and is updated as new official datasets are published.

Na h-Eileanan Siar (the Western Isles) has an exposed Atlantic island setting with low-lying coastlines, peatland and limited shelter and experiences cool, wet winters and mild summers, strongly influenced by maritime weather and frequent rainfall.

SEPA flood zone data places HS8 5JL in the higher flood risk band. 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.

Practical check: In a coastal flood risk area - ask about tidal flooding history and check the property's elevation relative to sea level. The nearest projected erosion zone is 117m 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.
