Specialist Procurement Advisor (Project) (Interims)

Job Description: Procurement Specialist (Business Case Delivery) About Southwark Council This is an exciting time to be involved in Southwark Council, as the organisation takes bold, strategic steps to transform how it delivers value for money while continuing to support its communities. Over the past six months, the Council has been working in close partnership with PwC to undertake a comprehensive and forward-thinking review of its third‑party spend. This work has focused on identifying innovative opportunities to drive efficiencies, strengthen commercial practices, and ensure sustainable service delivery across the organisation. Building on this momentum, PwC has developed a suite of 11 cross council business cases that set out a clear and ambitious roadmap for change. These business cases bring together a range of high‑impact initiatives aimed at reducing costs, managing demand more effectively, and improving outcomes for residents. Collectively, they represent a significant transformation programme, offering the opportunity to embed smarter, more strategic ways of working across the Council. The implementation of these proposals will be phased, with delivery structured into a series of waves to ensure manageable change and allow for lessons to be learned and applied as the programme progresses. The first wave is expected to focus on high priority and high‑spend areas, including Temporary Accommodation, Out‑of‑Borough Care Home placements, and Utilities. These areas have been identified as offering the greatest immediate opportunity to achieve savings and improve contract management, while establishing a strong foundation for subsequent waves of delivery. To support this programme, the Council is seeking an experienced Procurement Specialist who can take a hands‑on role in delivering the work. The successful candidate will bring proven, direct experience of operating in a similar environment, with a strong track record of leading and implementing procurement‑led savings initiatives. They will be expected to work at pace, engage effectively with stakeholders, and take a practical, delivery‑focused approach — including a willingness to “roll up their sleeves” and get into the detail to drive outcomes.
