Senior Financial Modeller in Watford

IN2 Consult has an exciting opportunity for a Senior Financial Modeller to work with a market leading client of ours based in Watford.

The Role

This is a senior modelling and analysis position sitting at the heart of the finance function, owning the group's core financial models and acting as a key advisor to senior leadership on strategic decision-making. You'll take ownership of the long-range plan model — keeping it current with actuals and the latest forecast, and evolving it in line with the organisation's planning systems. Alongside this, you'll lead on building and maintaining sales forecasting models and other Excel-based tools using modelling best practice, making sure they stay genuinely useful as the business changes shape.

A big part of the role is translating numbers into a story. You'll design input templates so financial data can be captured cleanly from across finance and commercial teams, then build outputs — using data visualisation, trend analysis and other techniques — that make results easy for non-finance stakeholders to understand and act on.

You'll also be relied on for:

• Efficient, well-controlled production of Excel-based reporting, with accuracy checks built in
• High-quality ad-hoc analysis to support strategic decisions across Finance, Commercial and the senior leadership team
• Adapting and building models for business case appraisal, scenario planning, stress testing and financial resilience work
• Making sure models and outputs meet both business planning needs and regulatory expectations — spotting gaps between the two and finding practical fixes
• Working closely with the Executive Team and wider stakeholders to deliver to deadline, even where requirements shift or aren't fully defined
• Supporting senior finance leadership with reporting packs, analysis and messaging for both internal leadership and external regulatory stakeholders
• Writing training materials and guides so the wider finance team can eventually take ownership of the models and reports themselves

What you'll bring

• ACA/ACCA/CIMA Qualified (ideally)
• A strong track record building and maintaining integrated Excel/PowerPoint models — P&L, balance sheet, cash flow, KPIs, budget vs actuals and trend analysis
• Experience supporting business planning cycles, producing models and reporting packs that genuinely shape senior-level decisions
• Solid grasp of how the three financial statements interconnect, and how operational performance feeds through to balance sheet and cash flow
• Comfort with agile scenario planning — reacting quickly when assumptions change and giving clear, decision-ready guidance
• A collaborative approach, happy working through problems constructively with colleagues across the business
• Strong communication and stakeholder management skills — able to cut through complexity and land clear recommendations under pressure
• The gravitas to work with senior leaders directly, challenge thinking where needed, and influence through well-evidenced insight
• A proactive mindset — flagging risks and opportunities early, working independently at pace, and adjusting how you communicate upward as needed
• Genuine comfort with ambiguity — able to structure a problem, chart a sensible path through it, and keep people aligned as things evolve
• Exposure to a cloud-based enterprise planning/reporting platform is a plus (system mapping/light configuration), though not essential
