• Ensure compliance with local legislative and regulatory requirements, identifying and managing financial risks.
• Oversee timely and accurate billing, managing customer queries and dispute resolution as needed.

• Qualified Accountant (ACA, ACCA, CIMA, or equivalent).
• Proven experience in financial planning, analysis, and business partnering within a large and complex organisation.
• Ability to manage multiple stakeholders and projects to tight deadlines.
• Confident and proactive, with the ability to challenge the status quo constructively.
• Strong analytical, communication, and influencing skills.
• Must hold (or be able to obtain) an Advanced Security Check (SC) clearance.

This is an exciting opportunity to contribute to a mission‑critical national programme - one that directly supports the safety and effectiveness of the UK's emergency services. You'll be part of a dedicated and high‑performing finance team that partners closely with technical and operational leaders to deliver a programme of national importance.

If you are a qualified accountant with strong business partnering experience and are looking to apply your expertise to a high‑profile, purpose‑driven project, we'd love to hear from you.
