UK2 - Preliminary Market Engagement Notice
Summary of the contracting process

The Office for Nuclear Regulation (ONR), a public authority within the central government of the United Kingdom, is in the planning stage of a procurement process for renewing its Technical Services Framework (TSF). The framework, identified by tender number ONR/T1111, focuses on services under the "Technical services" category (CPV code 71356000) and is expected to begin in November 2026. A key milestone is an upcoming Supplier Engagement Event on 26 February 2026, held via MS Teams, where ONR will outline tender requirements and timelines. Interested suppliers must register their participation by this date, offering a glimpse into the forthcoming open tender exercise aimed at bolstering the regulatory framework at nuclear sites across the UK.

This tender presents significant growth opportunities for businesses specializing in technical services, especially those experienced with nuclear industry regulations. Organizations capable of delivering high-standard technical solutions that ensure safety and compliance would be strategically positioned to benefit from this procurement. Given the scope of ONR's regulatory remit across 36 nuclear sites, potential suppliers should possess a proven track record in handling complex and high-stakes projects, adhering to rigorous safety and security standards. Participation in the Supplier Engagement Event offers a platform to engage directly with ONR, providing insights into procurement specifics that can guide proposal development for those keen on becoming pivotal partners in the TSF renewal process.

Notice Title

Provision of a Technical Services Framework (TSF) for the Office for Nuclear Regulation (ONR) - TSF4

Notice Description

The Office for Nuclear Regulation (ONR) is the independent UK regulator of the nuclear industry, including nuclear safety, security, and conventional health and safety at nuclear sites in the UK. 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 improves public confidence without compromising safety or security. 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. More detail can be found on our website: http://www.onr.org.uk/ To support its ongoing regulatory activities ONR is looking to renew its Technical Support Framework (TSF) towards the end of 2026. This is an early engagement event notice for suppliers of Technical Services interested in working with the Office for Nuclear Regulation (ONR).
