What is NUAR?

NUAR is a government digital service that provides instant access to a map of the underground pipes and cables in England, Wales, and Northern Ireland. It is improving the efficiency and safety of the way we install, maintain, operate, and repair our buried infrastructure.

Data is currently available from over 330 asset owners, including most of the major energy and water providers, several major telecommunications companies, smaller telecommunications providers, independent network data, transport organisations, and local authorities.

"The benefits NUAR could offer were quickly apparent and were brought into by the field teams during the trials; NUAR now makes the old process look very outdated and the flexibility it offers is hugely beneficial. This needs to be the industry norm going forward."

Norman Barnett, Framework Director, Esh Construction

"Before NUAR, we would have to log into multiple providers, each with a different user interface, some with more fields/questions, some with less, and different features – some better than others. Overall, a very jarring and inefficient way of working compared to NUAR. With NUAR – one login, one interface, all utilities, and more information – such as the depth (incredibly helpful!). If you like efficiency, and more information – sign up to NUAR."
