Finance Business Partner

We're looking for a commercially sharp Finance Business Partner to join our finance team on a 12-month fixed-term basis, covering a period of maternity leave. The role is expected to start in early January.

This is a high-impact, MD-facing role: you'll provide dedicated finance support to our Partner and Consumer divisions, trusted to challenge performance, sharpen decision-making and help the business understand what's really driving the numbers.

As a fixed-term cover, we need someone who can hit the ground running — confident partnering senior stakeholders from day one, quick to grasp the commercial model, and comfortable holding their own with Executive Committee (Exco) and Senior Management Team (SMT) stakeholders.

• Partner the Managing Directors and leadership of our Partner and Consumer divisions, providing the insight, challenge and financial perspective they need to drive performance and profitability.
• Get under the skin of each division's commercial drivers — and use that understanding to challenge performance, identify where we can do better, and hold the business to account against its plans.
• Own and develop meaningful KPIs and performance measures that drive the right behaviours and inform decisions.
• Lead budgeting, forecasting and monthly rolling P&L forecasting for your areas.
• Review revenue, cost of sales and margin across the full product portfolio, with the support of colleagues.
• Use automation and AI tooling to streamline recurring reporting and analysis — freeing up your time for the forward‑looking, strategic work that adds the most value.
• Contribute to month‑end and year‑end close, revenue & marketing accounting, balance sheet reconciliations and audit.
• Deliver ad‑hoc analysis and support profit optimisation projects across the business.

• A qualified accountant (ACA / ACCA / CIMA) with strong finance business partnering experience.
• Proven confidence partnering and challenging senior stakeholders — someone who questions assumptions, pushes for better, and is heard in the room at Exco / SMT level.
• A commercial mindset, with a track record of understanding business drivers and turning them into meaningful KPIs and insight.
• Comfortable using automation and AI tools to work smarter — or genuinely keen to.
• Strong analytical skills and advanced Excel; experience with Sage 200 (or similar) and Power BI is an advantage.
• Telecoms or ISP experience is strongly preferred, given the pace at which you'll need to get up to speed.

You’ll join a supportive, ambitious and trusted finance team that's investing in automation and AI to spend less time on the mechanics of reporting and more on the analysis and partnering that move the business forward.
