UK1 - Pipeline Notice
Summary of the contracting process

Sellafield Limited intends to procure design support services for infrastructure front-end enabling work. The requirement covers intelligent client support and oversight, development of the front-end pre-Outline Business Case, early design strategy, and niche nuclear and specialist support for conventional site infrastructure projects. The work is associated with Sellafield’s infrastructure programme and is to be delivered in the United Kingdom. It forms part of the wider Design Support Procurement, which includes plant-facing design office disciplines, site project office client support, remediation and legacy projects, retrievals client support, studies and engineering capability, and safety case work. The specific requirement here is infrastructure front-end enabling. The service category is design support services, under CPV 79933000.

This procurement is at the planning stage: Sellafield Limited has announced its intention to procure, but has not issued an invitation to tender. The buyer expects to use the Crown Commercial Service RM6356 framework, with a framework agreement involved. An associated competition notice is expected on 11 August 2026. The planned contract period is 1 October 2026 to 30 September 2030. The estimated value is £46 million excluding VAT, or £55.2 million including VAT, and the procurement is above the relevant threshold. One planned lot is identified and is suitable for SMEs. The strategy has changed from ten individual mini-competitions to three tranche competitions with sub-lots, managed as separate competitions through Atamis; the overall objectives, scope and requirements are unchanged.

This work is likely to suit consultancies and engineering organisations able to provide intelligent client support, infrastructure design oversight and front-end development before an Outline Business Case. Relevant suppliers will need credible nuclear-sector and specialist engineering capability, particularly for conventional site infrastructure, and the ability to support early design strategy and project decision-making. Experience across civil, structural, architectural, mechanical, electrical and instrumentation disciplines may be useful within the wider Design Support Procurement, alongside capability in manufactured products, process engineering, remediation and legacy projects, retrievals, studies, engineering and safety cases. The requirement is suitable for SMEs, including specialist firms that can contribute niche nuclear expertise, either directly or through the Crown Commercial Service framework.
