Job Description

Interim Finance Business Partner

Are you a commercially minded, qualified accountant who can hit the ground running and add value from day one?

We're looking for an experienced Interim Finance Business Partner to join a high-performing Finance team that partners, challenges and supports the business to drive value across the Group.

This is a hands-on role where you will act as the finance lead across several core business functions, taking ownership of cost management, performance insight and financial decision support across a significant cost base.

What you'll do:

As a key member of the Finance team, you will:

  • Partner closely with functional leadership teams to provide robust financial insight and constructive commercial challenge
  • Take ownership of cost base management across supported functions
  • Lead budgeting, forecasting and re-forecasting processes
  • Translate strategic objectives into clear financial plans, targets and KPIs
  • Deliver insightful monthly reporting, performance analysis and actionable recommendations
  • Provide rigorous financial evaluation of projects, investments and business cases
  • Proactively identify risks and opportunities, influencing stakeholders to drive performance
  • Act as the key link between Finance and the wider business
  • Maintain strong financial governance within a robust control environment

This is an influential role with regular exposure to senior stakeholders, where you will play a central part in ensuring financial discipline and supporting the delivery of stretch targets.

What you'll need:

This is a short-term interim assignment, so you must be comfortable stepping into a complex environment quickly and operating with minimal handover.

Essential:

  • Professionally Qualified Accountant (ACA / ACCA / CIMA or equivalent)
  • Proven experience in a Finance Business Partnering or Management Accountant role within a large organisation
  • Strong commercial acumen with experience supporting and challenging senior stakeholders
  • Demonstrable experience in budgeting, forecasting and cost management
  • Confidence communicating complex financial information clearly and credibly
  • Ability to manage multiple senior relationships and influence without direct authority
  • Experience working in fast-paced, change-oriented environments

Desirable:

  • Experience operating within a PLC or large corporate structure
  • Exposure to international organisations
  • Experience with SAP or similar ERP/reporting systems

The ideal candidate

You'll be commercially sharp, confident and pragmatic - someone who enjoys partnering with the business rather than simply reporting numbers. You'll be comfortable challenging constructively, influencing senior leaders, and driving financial discipline across core functions.

Most importantly, you'll be ready to step in immediately, build credibility quickly and make an impact.
