## Summary

The public procurement process under review is managed by the Defra group Commercial, focusing on the "Nuclear Energy Regulatory Justification Services Framework" within the environmental consultancy services industry category. The services framework is designed to support the UK's Department for Energy Security and Net Zero in managing the Justification process for new nuclear energy technologies. Located predominantly within the UK, including regions such as East Midlands and London, the procurement has reached the award stage as of 15th October 2025. The framework, which employs an open procurement method above the threshold, started on 1st October 2025 and will run for 60 months, with an optional extension of up to 18 months, potentially concluding by March 2032. The tender was initially set to close on 9th May 2025, and the contract is valued at £8.65 million.

This tender offers substantial business growth opportunities for companies specialising in environmental and technical consultancy services, particularly those with nuclear expertise. Businesses that can provide expert analysis, compile comprehensive reports, and deliver high-level technical advice and support will find this framework particularly advantageous. The inclusion of aspects suitable for SMEs underlines the accessibility for smaller enterprises to partake in substantial public sector work. With a focus on delivering critical services and collaborating closely with government agencies, participating businesses can significantly enhance their profile and credibility within the nuclear energy sector, paving the way for future opportunities and collaborations.

## Notice

The Authority has an agreement with the Department for Energy Security and Net Zero (DESNZ) to fulfil specific elements of the Justification process, as Justifying Authority for new nuclear energy technologies. The Authority's Nuclear Justification Team's role is to advise the SoS so that the SoS may determine the class or type of practice (CTP) that pertains to any application it receives from the nuclear industry and to decide whether the CTP is Justified or not. The Authority has established a framework of suppliers who have the requisite nuclear expertise to provide advice throughout the Justification process. The Authority's Nuclear Justification Team will use the services and deliverables provided by Framework Suppliers to inform its recommendations to the Secretary of State (SoS) in respect of an appropriate CTP and whether it is Justified. The Authority has established a framework of 8 (eight) suppliers that have the requisite nuclear expertise to provide the following services throughout the Justification process. * Undertake specific analyses and provide technical advice to inform Justification decisions on new nuclear energy technologies including but not limited to: o preparing detailed and comprehensive written reports, in an agreed manner and timeline, as required; o presenting, explaining and discussing report findings to/with the NJ Team, statutory consultees and other stakeholders as required; o other related analysis and technical advice as required. * Provide ongoing technical support to the NJ Team, including but not limited to: o providing expert knowledge, advice and support to enable interpretation and understanding of technical aspects and implications of data and information relevant to the Justification assessment process; o providing advice on robustness of evidence, gaps in evidence and methods; o providing access to expert bodies to approach to provide supplementary evidence where needed; o co-authoring draft and final Decision documents with the NJ Team o other related technical support as required. The Framework will commence on 01/10/2025 and operate for a period of 60 months with an optional extension period of up to 18 months to permit ongoing assessments to be completed, with a maximum end date of March 2032. The anticipated value figure is the estimated total value of the framework. The Authority does not guarantee any value or volume of business to suppliers through this agreement.
