Update on the National Underground Asset Register from the Government Digital Service

In this update, the Government Digital Service (GDS) outlines how the National Underground Asset Register (NUAR) is progressing towards becoming a statutory service and the principles guiding its next phase of development. The update reinforces that NUAR’s evolution continues to be shaped by close engagement with industry and feedback gathered through formal consultation.

GDS explains how forthcoming regulations will support the creation of a more complete and consistent picture of underground infrastructure, while ensuring NUAR fits sustainably within the existing safe digging landscape. Rather than replacing established processes, NUAR is being designed to work alongside them, recognising that accurate data, clear communication and asset‑owner expertise all play a critical role in reducing risk during excavation.

The blog also highlights practical steps being taken to strengthen integration, including new capabilities that alert asset owners when works are planned near their infrastructure. This enables more targeted risk assessment and guidance, helping ensure safety responsibilities remain clear and effective.

Finally, the update sets out the case for widening access to NUAR in a secure and controlled way. By enabling more users across the sector to benefit from shared underground asset information, NUAR is positioned to deliver broader safety, efficiency and economic benefits as adoption continues to grow.
