Summary of the contracting process

This procurement process involves Sellafield Ltd, which acted as the Intelligent Client for the DNWP commissioning support project, titled "DNWP009.161/LOT 2/Commissioning Support." The industry category falls under general management consultancy services, with additional classifications as decommissioning services, pertinent to the North West region of the United Kingdom. This tender reached the award stage, with a total contract value of £10,000,000 and work running from 19th December 2025 to 26th September 2026. The award was given to The Decommissioning Alliance II on the basis of a selective procurement method, specifically leveraging a call-off from a framework agreement. The tender process concluded on 15th December 2025, followed by the award publication on 3rd February 2026.

This tender presents substantial business growth opportunities, particularly for firms with expertise in management consultancy and decommissioning services. Businesses well-suited for such opportunities would ideally possess capabilities in overseeing complex projects or collaborating in integrated teams. Companies that can assist in the oversight or direct involvement in execution, such as management consultancies with existing frameworks or partnerships with decommissioning entities, stand to benefit greatly. However, SMEs and VCSEs were not specifically targeted in this tender, suggesting that larger enterprises or partnerships with more extensive resources might have a competitive edge.

Notice Information

Notice Title

DNWP009.161/LOT 2/Commissioning Support

Notice Description

The Client will act as the Intelligent Client for DNWP. "Intelligent Client" is defined as the in-house capability which has the responsibility for the ownership, management and delivery of a defined service or range of services. The Intelligent Client is capable of specifying requirements to external participants and managing the delivery outcomes, which requires the selection of appropriate participants and the management of relationships to maximise value. There are two separate delivery models that may be applied to each project / task, depending on the nature and scoping of the work. The role of the Client resources in each of these is different: * Model 1: Sellafield client oversight - Sellafield, as 'the Client', performs an oversight and assurance role, with delivery being solely conducted by the Contractor * Model 2: Integrated teams - Sellafield and the Contractor will work as integrated teams to deliver the scope of work (as set out in a specific Call-Off Contract). These teams may be Sellafield led or Contractor led and may be for a single aspect of the delivery lifecycle only, e.g. design, or right across the full lifecycle. Sellafield will still perform an Intelligent Client role under these arrangements in addition to their role as Intelligent Customer. Intelligent Customer is defined as the capability of an organisation to understand where and when work is needed; specify what needs to be done; understand and set suitable standards; supervise and control the work; and review, evaluate and accept the work carried out on its behalf.
