Financial Planning & Analysis

• Lead the monthly rolling forecast and annual budgeting cycle, driving cross-functional alignment and embedding a strategic focus on operational performance — ensuring high-quality, end-to-end integration of all inputs into financial models.
• Produce detailed bridge reconciliations and provide clear, insightful variance commentary on movements between rolling forecasts, budget, and prior submissions.
• Own and be fully accountable for the production and quality of detailed site-by-site budget packs, including rigorous analysis and clear narrative for the Group Finance function.

• Review and validate weekly performance updates prepared by the FP&A Analyst, ensuring the accuracy and integrity of all reported financial variances.
• Provide clear commentary on the Full Year Estimate section of the UK Finance report, ensuring timely escalation of key risks and issues as appropriate.

Business Partnering

• Lead the robust review of site performance, applying strategic challenge to drive accountability, enhance decision-making, and improve financial outcomes.
• Identify profit improvement opportunities across operational sites, working in close partnership with cross-functional stakeholders and the FP&A Analyst to co-develop and deliver high-impact action plans.
• Support and maintain relationships with key supply chain partners — including feedstock providers and hauliers — to ensure costs are minimised where possible.
• Oversee the strategic optimisation of energy assets, partnering with operational teams and the FP&A Analyst to monitor performance, evaluate current market conditions, and maximise site profitability.
• Lead the identification, assessment, and management of financial risks and opportunities, driving proactive mitigation plans and value creation in partnership with key stakeholders.
• Advise and influence senior leadership to shape strategic decision-making and drive alignment to business priorities.
• Support external engagement to deliver sustainable cost reductions and supply diversification across critical spend categories — including utilities, consumables, and maintenance — undertaking regular contract reviews with Operations to optimise pricing, performance, and value.
