Description
Sellafield Ltd plans to call for competition for ICT Infrastructure & Application Management Services (IAMS) via the Technology Services 4 (TS4) Framework Agreement (RM6190). The call for competition is anticipated to commence in late May 2026. Participation in the Invitation to Tender (ITT) will be restricted to suppliers appointed to both: • TS4 Lot 4 – Infrastructure Management • TS4 Lot 5 – Applications & Data Management Note: This notice replaces the UK1 notice issued on 30/09/2025. The previously stated two Lot structure and contracting approach has been revised. The requirement will now be delivered through one single contract covering both applications and infrastructure scope, without Lots. This consolidated approach streamlines delivery, reduces duplication, and results in a revised estimated contract value of £76.1m. Update 02/03/2026: The contract duration has been updated to 7 years (revised from the previously stated 5 + 2 years).
This page represents one OCDS contracting process. Notices can be revised over time. Values may be estimates, award values or contract values and should be read with their displayed stage and date.
