Flooding from rivers and the sea
We checked each postcode centre against the Environment Agency's flood zones.
All 8 postcodes we checked are outside mapped river and sea flood areas. Homes nearer a river or the coast can still be in one.
Surface water flooding
Flooding from heavy rain that can't drain away.
- Low: 1 of 8 postcodes
- Very low: 7 of 8 postcodes
Radon
From the UK Health Security Agency's map of each 1 km square.
At all 8 postcodes we checked, parts of the surrounding square are a radon Affected Area. The highest is up to 10–30% of homes above the action level.
The map shows the highest value in each square, not a measurement for any home. A three-month test tells you about a particular house.
Ground stability
British Geological Survey ratings for the surrounding area, not a particular plot.
No moderate or significant natural ground hazards near the postcodes we checked.
Non-coal mining hazard is low or none at every postcode we checked.
Old landfill sites
Historic landfill sites within 500 m of each postcode centre.
Most old landfill causes no problems, but a home on or next to one can be harder to mortgage.
Conservation areas and listed buildings
Whether each postcode centre falls in a conservation area, on a listed building's site, or under similar protections.
None of the 8 postcode centres we checked falls in a conservation area or on a listed building's site.
Broadband and mobile
