Buildings for which there is no currently valid postcode
Postcode data for some premises is incomplete, particularly if only recently been built. A radon search based on geographical co-ordinates can be provided by Public Health England or the British Geological Survey. Alternatively if you have an iPad or iPhone, you can locate the property on a map or by entering a grid reference using the iGeology app.
Sites for development
For plots of land or development sites which may not yet have a postcode or if this site is for redevelopment, you should undertake a GeoReport provided by the British Geological Survey.
This report is not appropriate for large buildings of more than 25 metres in length. Searches covering a larger area can be obtained from the British Geological Survey.
