The Cabinet Office has restructured its procurement oversight arrangements, replacing the Procurement Review Unit (PRU) with Procurement Compliance & Oversight (PCO). This reorganisation takes effect in conjunction with the launch of the Government Commercial Agency (GCA), which replaces the Crown Commercial Service (CCS) as of 1 April 2026. The GCA launch is a significant structural change for government procurement, merging the CCS and central commercial teams within the Cabinet Office to consolidate and centralise government procurement under one agency. Responsibility for procurement oversight under the Procurement Act 2023 (PA 2023) is split between the Public Procurement Review Service (PPRS), the Procurement Compliance Service (PCS), the Debarment Review Service (DRS) and the National Security Unit for Procurement (NSUP). The PPRS, PCS and DRS previously formed the PRU, with the NSUP working separately within the Cabinet Office. With the PRU disbanded, the existing services continue in a restructured form. The PPRS and PCS now form the PCO, with the DRS transferring to the GCA. The NSUP, which works closely with the DRS, remains based within the Cabinet Office. New guidance on the PCO has been published and previous guidance on the PRU has been withdrawn. Further updates to the Cabinet Office guidance on PA 2023 oversight are anticipated.
