Question to the Department for Science, Innovation & Technology:

To ask the Secretary of State for Science, Innovation and Technology, whether the National Underground Asset Register will enter full operational service on 1 January 2026 for safe digging and what formal safety and risk assessments the Department has received in relation to NUAR, including from the Health and Safety Executive and trade unions.

The National Underground Asset Register (NUAR) is operational now, and in January 2026 all of its core functionality for use in street works will be in place. Development and continuous improvement will continue beyond this point, informed by user feedback. NUAR has been developed to give undertakers standardised, efficient access to asset information for carrying out street works. Feedback from users demonstrate that NUAR already delivers major improvements over existing processes for gathering information about buried utilities. No centralised risk assessment has been delivered as each organisation remains responsible for determining how NUAR fits into its safe working practices and for conducting any necessary risk assessments and ensuring that relevant guidance is adhered to. We will be carrying out a robust programme of monitoring and evaluation which will review multiple indicators to understand the impact of NUAR on safe working practices.
