Radon : England and Wales GeoReport

Radon : England and Wales GeoReport

This is an advisory report on the requirement for radon protective measures in new buildings, conversions and extensions to existing buildings. The report also indicates whether a site is located within a radon affected area.

This report is based on the joint BGS - UK Health Security Agency (UKHSA) radon potential data and complies with "BR211 Radon: Guidance on protective measures for new buildings (2023 edition)", which also provides guidance on what to do if the result indicates that protective measures are required.

Please consult your Buildings Inspector, who will advise on which report is most appropriate.


A revised radon map and new dataset was released on 1st December 2022. The Radon: England and Wales, and Radon: Scotland reports are now based on the new radon dataset. The map and dataset for Northern Ireland is not changing so addresses in Northern Ireland are not affected.
