Groundsure Underground

Buyers and developers are becoming increasingly concerned about the impact that underground rail tunnels could have on a property or site.

The Groundsure Underground report has been developed to identify whether a property could be affected by tunnel networks that would unlikely be detected in a standard conveyancing search.

This report is specifically designed for properties in the London area as it includes full data sets on all London railways, underground, stations and railway projects.
