Provision of a Technical Services Framework for the Office for Nuclear Regulation
Authority: Office for Nuclear Regulation (Central government)
What is being bought4 lots · detail below
Published requirement descriptionONR is the independent UK regulator of the nuclear industry, including existing, decommissioned and new reactors. It employs more than 650 professional staff, with specialist regulatory roles (e.g. nuclear safety/security/safeguards); corporate professions including Policy and Communications, Finance, IT, and Human Resources, and other core functions. ONR's Head Office, housing its main functions, is in Bootle, Liverpool, with two smaller offices in London and Cheltenham.
ONR independently regulates nuclear safety and security at 36 nuclear licensed sites in the UK. We also regulate transport and ensure that safeguards obligations for the UK are met. Our duty is to ensure that the nuclear industry controls its hazards effectively, has a culture of continuous improvement and maintains high standards.
The nuclear industry is undergoing rapid change and our role as a regulator is vital in ensuring new nuclear facilities are designed, built and operated to the highest standards, and in a manner that engenders public confidence.
We also oversee the decommissioning of nuclear sites and cooperate with international regulators on safety and security issues of common concern, including associated research. Our work is critical to the protection of society at large so it is important that we do it with rigour, diligence and with an appropriate level of assurance.
Whilst ONR continues to invest in its staff to build capability and resilience, we also recognise the importance of operating efficiently and effectively through its relationships with stakeholders such as industry bodies, the supply chain and academic institutions to help inform our capability, research and decisions. At present, ONR secures technical services through framework contracts with a number of specialist service providers and / or through standalone procurement activity.
Following a review of its extant arrangements and to ensure effective support to its on going regulatory activity, ONR intends to establish a new Technical Services Framework, with effect from 01 November 2026.
The proposed Technical Services Framework will comprise the following four Lots:
Lot 1 - Fault Analysis
Lot 2 - Civil Engineering & External Hazards
Lot 3 - Specialist Engineering and Technical Services
Lot 4 - Digital Technology & Cyber Security
The full Framework scope and details of the specific disciplines within each Lot are provided in the Bidder Pack which also contains the full details of the opportunity, the tender process and how to submit a tender. The Bidder Pack is available via the ONR

Lots and requirements (4)Procurement structure
4 lots · all with a published value · same evaluation weights on every lotEvery one of these 4 lots carries the same published figure, £20,000,000: it is the framework's maximum for the whole notice, not each lot's own budget, and no share per lot is published.

- Quality: Technical Social Value Presentation/Interview
- Commercial: Schedule of Rates
- Price carries 20 of 100 points: a 10% discount moves about 2 points. The method statement decides this lot, not the discount.
- “Provision of a Technical Services Framework for the Office for Nuclear…” is a framework: the contest is a place on its panel, not a single contract: call-offs may be direct or by further competition.
Price arithmetic assumes straight proportional scoring; the tender pack may use another formula.
