Located in Drigg, Cumbria, the project is aimed at delivering site works, asset refurbishment, and infrastructure projects for the Low Level Repository (LLWR) Site. The process has progressed to the award stage, with a contract valued at £49.6 million awarded on 7th August 2025. An open procedure procurement method was employed, adhering to the GPA standards.
