Assurance & Internal Audit

Why Assurance Matters

Boards and investors need confidence that governance, financial, and operational controls are working as intended. Without independent assurance, risks can go unnoticed, leaving organisations exposed to inefficiency, error, or reputational damage.

A Partner for the Boardroom

We bring senior-level experience, ensuring our assurance work connects with strategy, governance, and risk. Our independence gives boards the confidence to act decisively on findings.

Assurance That Adds Value

With Libertas, assurance and audit aren’t just about compliance — they’re tools for smarter leadership and stronger resilience.

Matthew Comins

“A growth business requires both an ambitious driver and a reliable rudder. I work alongside entrepreneurs to provide that strategic direction, ensuring their financial infrastructure supports their commercial ambition.”

Matthew co-leads our Commercial Performance practice. A highly experienced fractional CFO with over 25 years of corporate and SME financial expertise, Matthew specialises in helping family-owned, entrepreneurial, and mid-market businesses scale sustainably and achieve their long-term strategic goals.

Matthew’s career spans a diverse array of sectors, geographies and business structures. Having completed his early training within public accounting in South Africa, he spent several years in senior finance leadership roles for a NYSE-listed multinational, establishing new regional offices across East Africa (including Tanzania, Zambia, and Mozambique) and serving as Regional Financial Controller in Malawi.

Following this multinational experience, Matthew spent a decade as Group CFO for a fifth-generation family-owned enterprise. Under his financial stewardship, the company diversified from being a solely agricultural-focussed business into property development, insurance, veterinary pharmaceuticals and technology, successfully scaling its turnover from R250 million to R2.5 billion. This extensive experience makes him uniquely equipped to navigate the highly nuanced dynamics of multi-generational family businesses and fast-growth corporate scaling.

Complementing his technical financial expertise, Matthew brings more than 15 years of board-level experience to Libertas. Having served as a Board Chairperson, Independent Non-Executive Director, and Risk Committee Chair he understands how to align financial reporting with robust corporate governance.

Now based in Yorkshire, Matthew works with ambitious businesses across the North of England. His collaborative approach focuses on partnering with a client’s existing finance team or external accountants, acting as a trusted sounding board and commercial strategist for business owners.
