TN1 1AP - Flood, Heat, Air & Subsidence Risk - Royal Tunbridge Wells (TN1)

Tunbridge Wells, Royal Tunbridge Wells (TN1)

Climate risk summary for TN1 1AP

Heat risk is Medium. Air quality is Medium at PM2.5 6.8 μg/m³, above the WHO annual guideline of 5 μg/m³ (Defra UK-AIR).

• Flood: No flood-risk band is published for this postcode in the current dataset releases - a data-coverage gap rather than a rating. The national agencies' address-level flood services cover every property.
• Heat: Warm spells will be more common in future.
• Air quality: PM2.5 6.8 µg/m³ - above the WHO annual guideline of 5 µg/m³ (Defra UK-AIR PCM model, council-level average - every postcode in this council shows this value).
• Green space: 98% of households here have accessible green space within a 15-minute walk (the government's Environmental Improvement Plan standard), and 30% have a park or green space within a 200m walk of their door - above the England median (Defra, 2025).

What is the flood risk in TN1 1AP?

An official flood-risk band is not available for TN1 1AP in the current dataset releases used by LocalRisk. This is a data-coverage gap rather than a low-risk rating. For a property-level reading, the Environment Agency's Check Your Long-Term Flood Risk service covers every address in England.

What is the heat risk in TN1 1AP?

Heat risk at TN1 1AP 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 TN1 1AP?

Air quality at TN1 1AP 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.

Where does this data come from?

This LocalRisk report for TN1 1AP 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 Tunbridge Wells and is updated as new official datasets are published.
