This Output Checking System (OCS) functionality will allow UKB to enhance the security of the UKB-RAP, reduce the risk of advertent and inadvertent data breaches and importantly increase the trust and transparency of the UKB resource. UKB intends to commence a procurement exercise to procure a replacement for the current UKB-RAP in 2027, which will come into effect in 2028. The OCS will need to be integrated with the new UKB-RAP. To develop and deliver the OCS, UKB is separating the procurement into two elements which will need to be fully interoperable: 1. OCS User Interface (UI) and Workflow (subject to a separate tender exercise completed via the CCS G-Cloud 14 framework): The development of a seamless UI and Workflow for the OCS, including secure movement of data and integration with existing UKB infrastructure. 2. The OCS Decision Engine (this procurement): The development of the core algorithms to allow an automated assessment of the data being egressed, giving an overall confidence assessment score and a Red/Amber/Green (RAG) rating for decision making The OCS Decision Engine is made up of two components: 1. Data Trust Engine: reviews the egressed file(s) from UKB-RAP to detect the presence of sensitive information. Through the application of transparent, heuristic rules and configurable thresholds, the Data Trust Engine will create a score for how 'disclosive' the egressed data is that, when coupled with the researcher confidence score below, provides a Red (fail), Amber (unclear) or Green (pass) egress rating. 2. Researcher Behaviour Engine: derives the overall credibility of a given researcher within AMS and UKB-RAP, and assigns a confidence score, which will dictate how human-review decisions are made for 'Amber' outcomes from the Trust Engine. This procurement relates to a development partner to design and deliver the OCS Decision Engine, which will include the Data Trust Engine and Researcher Behaviour Engine. • The evaluation was concluded and a decision to award was made on Friday 22 May 2026 • UK Biobank has provided an assessment summary to each supplier on Friday 19 June 2026 • The standstill period ran until midnight on 30 June 2026 ## Lots (1) ### Lot 1: Untitled lot - **Lot id:** `1` - **Status:** complete - **CPV codes:** 72000000 - **Delivery regions:** UKD - **Delivery countries in notice:** GB - **Estimated Value:** £2,000,000 - **Contract Period:** 30/07/2026 to 30/07/2029 - **Renewal published:** yes ## Awards & Winning Suppliers (1) - **Award:** 1 (active) - Supplier(s): **Kainos** - Supplier identifiers: `GB-FTS-48324` - Value: £2,000,000 (exc.
