Core HR Software as a Service (SaaS) Licensing to include Success Plans

This UK06 Contract Award Notice outlines Sellafield Ltd's (Sellafield) intention to award a contract to SAP UK Ltd for a Software as a Service (SaaS) agreement for it's Core HR requirements. This follows the prior UK05 Transparency Notice issued on 1st April 2026 (2026/S 000-030499) for a number of planned procurements to implement SAP's Enterprise Resource Planning (ERP) cloud-based solution as an upgrade from Sellafield Ltd.’s legacy on-premise SAP ERP solution; which is affected by an end of supported life constraint, to a replacement and fully supported SAP ERP SaaS solution. Sellafield operates in a complex, highly regulated nuclear licensed site environment and regulated by the UK Office of Nuclear Regulation (ONR). To mitigate against the version of SAP Business Suite 7 (BS7) ERP becoming unsupported, Sellafield is proposing to migrate these core services in 4 phases as follows: 1. Procurement of SAP Cloud ERP Core HR SaaS Licenses (SuccessFactors (Incl. ESM) and SAP Success Plans) around December 2026 (C15136) - The subject of this UK06 Contract Award Notice. 2. Procurement of a specialist Implementation & Support Partner (ISP) for Core HR service around April 2027 (C15137) 3. Procurement of SAP Cloud ERP S/4HANA + EAM SaaS Licences around July 2027 (C23156) 4. Procurement of a specialist Implementation & Support Partner (ISP) for S/4HANA + EAM service around July 2027 (C15139) As background, Sellafield operates its core business processes through a mature SAP platform covering Finance, HR, Procurement and Warehousing operations. The current ERP system (SAP BS7) which is provided by SAP, will no longer be supported after December 2030. Due to extended SAP support deadline to the SAP ECC Human Capital Management (HCM) there is a threat that beyond that date critical HR systems will fail, which may result in data integrity issues business disruption, non-compliance and increased manual interventions. Sellafield intends to make a Direct Award to SAP UK Limited under a Master Agreement with a term of 7 years, to provide the initial Core HR element of a new SAP ERP Cloud system and subscription model for the various modules to replace legacy ERP solution. This includes a provision for servicing NDA Group Operating Companies via Sellafield. Sellafield’s justification for such a direct award to SAP UK Limited is under Paragraph 7 “Additional or repeat goods, services or works under 7 (b) justification, in addition to absence of competition due to technical reasons under Paragraph 6 “Single Suppliers” under the Procurement Act 2023 (PA23) justifications.
