Radon in Nottingham, district by district
At 52 of the 64 postcodes we checked across the 7 Nottingham postcode districts with a guide, parts of the surrounding 1 km square are a radon Affected Area (in NG1, NG3, NG6, NG7, NG8 and NG11).
The highest band found is up to 10–30% of homes above the action level (in NG6). The map describes each square, not any home: only a three-month test measures a house.
From UK Health Security Agency and British Geological Survey radon map, checked at the sampled postcodes of each district guide in October 2026. Facts with their sources, not a rating: a district with nothing found isn't safe, and one with findings isn't unsafe. The maps describe the ground, not any home.

What it means when you buy in Nottingham
It depends on the rocks and soil. The radon map gives each 1 km square the share of homes estimated to be above the action level:
- Below 1%: the square isn’t a radon Affected Area.
- 1% or more: it’s a radon Affected Area, and a test is recommended.
- The map describes the area, not the house: only a test measures a particular home.
- Raised radon can usually be reduced, for example with a radon sump.
Raised radon is common in some parts of the country and rare in others. Knowing the area’s potential tells you whether to ask about testing and protection before you commit.
A higher-radon area isn’t a reason on its own to walk away. Raised levels in a home can usually be reduced, for example with a radon sump, and a specialist can quote for it.
Questions to ask about a home in Nottingham
- Has the house been tested for radon, and what was the result?
- Was radon protection fitted when it was built or since?
- If levels were raised, what was done, and was it tested again afterwards?
The full report checks the house itself, not the postcode, and ties each question to what it found. See an example report.
