An exciting opportunity has arisen for an experienced Transformation Portfolio Office Manager to shape and influence enterprise-level transformation across a leading UK utility provider.
You will not be managing the day-to-day delivery of individual projects. Instead, you will sit at the strategic centre of the transformation agenda, providing governance, oversight and assurance across the full portfolio of change initiatives.

- Data Integrity: Serve as the single source of truth for portfolio performance, maintaining advanced Excel models and analytical frameworks.
- Strategic
Coaching:
Partner with internal teams, Audit and Assurance to coach stakeholders on governance best practices and drive continuous improvement.
- Portfolio
Experience:
Proven experience in a Transformation Office, Enterprise PMO or Portfolio Office overseeing complex change portfolios rather than project-level delivery. - Advanced Technical

Expert proficiency in Power BI (dashboard development, KPI tracking) and Excel (complex data manipulation, reporting models) is essential. - Executive Reporting: Track record of producing high-level reports and presentations (Advanced PowerPoint) for Board and Executive audiences.
