## Summary

The Department for Science, Innovation and Technology has extended the contract for the National Underground Asset Register (NUAR) Transition Service in partnership with AtkinsRéalis UK Ltd. This contract focuses on maintaining parts of the NUAR Service until its expected transition to a future operator. The procurement is classified under software programming and consultancy services, and employs a selective procurement method via a call-off from the RM6195 Big Data and Analytics Framework. The contract period spans from 1st April 2025 to 31st March 2026, with a contract value of £3,434,270.63. The procurement stage is complete, with the award date noted as 31st March 2025.

This tender presents significant opportunities for businesses involved in software and consultancy services within the data management and utility sectors. Companies with expertise in big data frameworks and underground asset management would find this tender particularly beneficial for strategic growth, especially those able to offer innovative solutions to improve safety and efficiency in utility management. Though the opportunity favours larger enterprises due to the nature of the procurement method and framework agreement, it highlights possibilities for further engagement in public sector contracts focused on technological and infrastructural services.
