I’ve spent 25 years in financial modelling — from the deal rooms of a Big 4 accountancy firm to the boardrooms of FTSE-listed corporates, private equity houses, and infrastructure funds. I’ve built, reviewed, and stress-tested models that have underpinned billions of pounds of investment decisions across a diverse range of sectors.
My career started in the financial modelling practice of a Big 4 accountancy firm, where I developed models across sectors including banking, oil and gas, retail, infrastructure, energy, real estate, healthcare, and transport — working on engagements for both listed companies and private equity-backed transactions. Over the years I’ve reviewed models produced by all four of the Big 4 firms, as well as boutique advisory houses and in-house finance teams, giving me a rare perspective on what works, what breaks, and where errors hide.
During my time at the Big 4, I developed the firm’s peer review methodology for financial models and personally trained all 30 members of the modelling team in its application. That methodology ensured every model leaving the practice met a consistent standard of quality, auditability, and structural integrity – and it shapes how I approach model review work to this day.
I was also responsible for the development and maintenance of the firm’s internal model build and utility Excel add-in — a VBA-powered toolkit used across the modelling practice to enforce consistency, accelerate common build tasks, and embed best-practice standards directly into the modelling workflow. That experience gave me a deep understanding of Excel at the programmatic level: not just building models in spreadsheets, but building the tools that make modellers more productive and less error-prone.
I founded Financial Modelling Consultants to provide businesses, investors, and advisors with access to genuinely senior modelling expertise without the overheads and mark-ups of a large firm. When you work with us, the person you brief is the person who builds your model — there’s no delegation to junior staff, no learning on your project, and no surprises. Every model I deliver is built to the same standard I’d expect if I were the one signing off on the investment.
I believe a great financial model should be transparent, auditable, and built for purpose. It should tell a clear story, withstand scrutiny, and give decision-makers the confidence to act.
I’m an active member of the financial modelling community, including Full Stack Modeller — the award-winning global community of finance professionals focused on Excel mastery, financial modelling, data visualisation, and analytics. I believe that staying current with new functions, techniques, tools, and ideas is essential in a discipline that never stops evolving — whether that’s new Excel capabilities like dynamic arrays and LAMBDA, advances in Power Query and Power BI, or emerging approaches to model design and automation. Equally, I’m committed to sharing the lessons from my 25-plus years of hands- on experience, contributing to discussions, challenges, and knowledge-sharing that raise the standard of modelling practice across the profession.
