Facts from official records at sample postcodes, not a rating of OL9 or of any home.
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.
- Very low: 7 of 7 postcodes
We couldn't check 1 postcode when this guide was built, so they aren't counted above.
Radon
From the UK Health Security Agency's map of each 1 km square.
At 3 of the 8 postcodes we checked, parts of the surrounding square are a radon Affected Area. The highest is up to 1–3% 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.
- Clay shrink-swell: moderate near all 8 postcodes we checked
- Landslides: moderate near all 8 postcodes we checked
Non-coal mining hazard is low or none at every postcode we checked.
Ask your surveyor to look for cracking and movement, and the seller about subsidence claims.
