About NUAR

The Geospatial Commission is building a digital map of underground pipes and cables that will revolutionise the way we install, maintain, operate and repair our buried infrastructure - the National Underground Asset Register (NUAR).

NUAR will improve the efficiency and safety of underground works by creating a secure, auditable, trusted and sustainable platform. It will provide a consistent, interactive digital map of buried asset data, accessible when, where and how it is needed by those planning and executing excavations on behalf of underground asset owners. It will also lead to enhanced communication between parties and improve data quality.
