What is being bought

The Government is committed to a programme of new nuclear projects beyond Sizewell C, giving industry and investors the confidence they need to deliver projects at speed. Great British Energy - Nuclear (GBE-N) was launched as part of the government's Powering Up Britain plan. The first priority for GBE-N was to launch a competitive process to select small modular reactor (SMR) Technology Partners, which was the subject of this Procurement. GBE-N sought to procure Technology Partners that will provide design, development, manufacturing, supply, installation and commissioning of various products, equipment or services related to the key plant required for SMR nuclear generation, including but not limited to reactor, steam generation, turbine, electrical generation, as well as the integrated design of these component parts. The Technology Partner will be responsible for delivery to site of a designed and tested solution, a complete set of interface specifications, and installation and commissioning of the solution. GBE-N intends to establish a Project Development Company (Project Devco), which will provide developer capabilities. The Technology Partner will be responsible for joint working with a Project Devco to connect and test interfacing equipment, complete integrated system testing and complete final commissioning and handover. Subject to affordability, GBE-N reserved the right to make up to four awards. However, GBE-N reserved the right to award three, two or only one contract(s) to Technology Partner(s), or not to make any award at all. Upon conclusion of the procurement process GBE-N awarded one Technology Partner contract. The decision in relation to how many Technology Partners were awarded contracts was taken having regard to the quality of tenders, as well as affordability and value for money considerations. GBE-N intends to award a two-stage contract for the Technology Partner for the provision of their Site Specific Design Solution, with the first stage being design and the second stage being the supply. The second stage is conditional upon the exercise of an option by GBE-N. GBE-N reserves the right to exercise this option for manufacture and supply, installation and commissioning subject to satisfactory delivery against agreed milestones and achievement of Final Investment Decision (FID). GBE-N will make available Site Specific Design Solution development costs. The Supply Phase i.e. the period from FID to Commercial Operation Date (COD) for a first of a kind (FOAK) project in the UK will include the manufacture, supply, installation and commissioning of the Supply Works on a value-for-money basis by the Technology Partner and provision of fuel assemblies and supporting maintenance services up to and including first refuelling outage. GBE-N reserved the right to require Technology Partners to adopt specific supply solutions.

Comparable-procurement analytics

Benchmarked against retained Find a Tender procedures with CPV division 09. The category anchor is Electricity (09310000); this is a deliberately broad market comparator. The comparison is shown at several levels rather than pretending one company or region is always the best benchmark.

Comparison setProceduresReported bids per procedureNamed award suppliersPrice evidence
Market: CPV division 091,1393 median · 39.6 average (418 of 1,139 with a bid count)5.8 average (471 of 1,139 with named award suppliers)Not published

“Reported bids” is an official aggregate, sometimes reported per lot; it is the closest available competition measure. “Named award suppliers” are winners, not all applicants.

Price-outcome signal

Not enough comparable procedures currently publish both a GBP tender value and a usable lowest-valid-bid value to calculate a responsible price-reduction benchmark. Tenderline deliberately does not infer a saving from named award suppliers or from missing award values.

  "description": "The procurement was conducted with Great British Nuclear (GBN) as the contracting authority. On 06 June 2025, the Secretary of State for the Department of Energy Security and Net Zero instructed GBN to update the company name to Great British Energy - Nuclear. This change came into effect on 10 June 2025.\nThe estimated total value within the tender notice for the two-stage TP Contract was £20,000,000,000 excluding VAT. This value was indicative only and based upon GBE-N's initial understanding of the potential costs of developing a first of a kind technology.  This estimated total value was based on the fact that in the tender notice GBE-N reserved the right to make up to four awards, although GBE-N also reserved the right to award three, two or only one contract(s). GBE-N has ultimately decided to award only one TP Contract and the contract award notice value reflects this.\nThe forecast Stage 1 price of the TP Contract is £359,000,000. This forecast price may change.\nThe forecast Stage 2 price of the TP Contract is approximately £8,168,000,000. This forecast price is indicative only as the pricing mechanism for Stage 2 remains subject to negotiation during Stage 1.",

    "description": "The Government is committed to a programme of new nuclear projects beyond Sizewell C, giving industry and investors the confidence they need to deliver projects at speed. Great British Energy - Nuclear (GBE-N) was launched as part of the government's Powering Up Britain plan. The first priority for GBE-N was to launch a competitive process to select small modular reactor (SMR) Technology Partners, which was the subject of this Procurement. \nGBE-N sought to procure Technology Partners that will provide design, development, manufacturing, supply, installation and commissioning of various products, equipment or services related to the key plant required for SMR nuclear generation, including but not limited to reactor, steam generation, turbine, electrical generation, as well as the integrated design of these component parts. The Technology Partner will be responsible for delivery to site of a designed and tested solution, a complete set of interface specifications, and installation and commissioning of the solution. \nGBE-N intends to establish a Project Development Company (Project Devco), which will provide developer capabilities. The Technology Partner will be responsible for joint working with a Project Devco to connect and test interfacing equipment, complete integrated system testing and complete final commissioning and handover. \nSubject to affordability, GBE-N reserved the right to make up to four awards. However, GBE-N reserved the right to award three, two or only one contract(s) to Technology Partner(s), or not to make any award at all. Upon conclusion of the procurement process GBE-N awarded one Technology Partner contract. The decision in relation to how many Technology Partners were awarded contracts was taken having regard to the quality of tenders, as well as affordability and value for money considerations. \nGBE-N intends to award a two-stage contract for the Technology Partner for the provision of their Site Specific Design Solution, with the first stage being design and the second stage being the supply. The second stage is conditional upon the exercise of an option by GBE-N. GBE-N reserves the right to exercise this option for manufacture and supply, installation and commissioning subject to satisfactory delivery against agreed milestones and achievement of Final Investment Decision (FID). GBE-N will make available Site Specific Design Solution development costs. The Supply Phase i.e. the period from FID to Commercial Operation Date (COD) for a first of a kind (FOAK) project in the UK will include the manufacture, supply, installation and commissioning of the Supply Works on a value-for-money basis by the Technology Partner and provision of fuel assemblies and supporting maintenance services up to and including first refuelling outage. GBE-N reserved the right to require Technology Partners to adopt specific supply solutions.",

  "description": "The procurement was conducted with Great British Nuclear (GBN) as the contracting authority. On 06 June 2025, the Secretary of State for the Department of Energy Security and Net Zero instructed GBN to update the company name to Great British Energy - Nuclear. This change came into effect on 10 June 2025.\nThe estimated total value within the tender notice for the two-stage TP Contract was £20,000,000,000 excluding VAT. This value was indicative only and based upon GBE-N's initial understanding of the potential costs of developing a first of a kind technology.  This estimated total value was based on the fact that in the tender notice GBE-N reserved the right to make up to four awards, although GBE-N also reserved the right to award three, two or only one contract(s). GBE-N has ultimately decided to award only one TP Contract and the contract award notice value reflects this.\nThe forecast Stage 1 price of the TP Contract is £359,000,000. This forecast price may change.\nThe forecast Stage 2 price of the TP Contract is approximately £8,168,000,000. This forecast price is indicative only as the pricing mechanism for Stage 2 remains subject to negotiation during Stage 1.",
