Description
AWS seeks to engage an experienced and independent assurance provider to support the organisation in demonstrating the delivery of Ofwat's Price Control Deliverables under the PR24 framework as well as supporting ad-hoc assurance projects. The assurance partner will work alongside internal delivery teams but will retain a clear separation from programme execution, offering external validation and audit-ready reporting that underpins regulatory submissions. The supplier will ensure that evidence provided to Ofwat meets required standards of accuracy, traceability, and defensibility. The total estimated expenditure over the full potential eight-year duration is £4 million.
