At a glance

Facts from official records at sample postcodes, not a rating of WN4 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.

  • High: 1 of 8 postcodes (WN4 9RP)
  • Low: 2 of 8 postcodes
  • Very low: 5 of 8 postcodes

Medium means a 1% to 3.3% chance of flooding each year, and high more than that. It changes over a few metres, so look at the drainage when you view.

Radon

From the UK Health Security Agency's map of each 1 km square.

At 5 of the 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.

  • WN4 9TP: 1 site within 500 m, nearest 410 m
  • WN4 9RP: 1 site within 500 m, nearest 340 m
  • WN4 9BQ: 1 site within 500 m, nearest 460 m
  • WN4 9RA: 1 site within 500 m, nearest 60 m

Most old landfill causes no problems, but a home on or next to one can be harder to mortgage.
