More than accountants — your outsourced finance team.
Ernest & Co is a UK accountancy firm giving growing businesses access to professional financial expertise — without the cost of a full in-house finance department.
Our story
Ernest & Co is a UK accountancy practice, founded on a simple belief: small business owners deserve the same calibre of finance expertise as the largest companies — delivered with warmth, clarity and zero jargon.
Today we work with startups, sole traders, landlords and limited companies across the UK, with a particular passion for supporting underrepresented founders and diverse businesses to grow with confidence.
Ernest Tumuhairwe ACMA CGMA, Founder
Chartered Management Accountant supporting UK SMEs.
Ernest is a Chartered Management Accountant (ACMA) and Chartered Global Management Accountant (CGMA) with over a decade of experience in finance, reporting and business advisory across industry and practice.
He has supported organisations from early-stage startups to established SMEs — leading month-end close, cash flow forecasting, budgeting, and strategic decision-making alongside founders and management teams.
At Ernest & Co, he brings that same boardroom-level insight to UK small businesses through an outsourced finance model — giving owners a finance director, management accountant and bookkeeper on tap, without the overhead of an in-house team. The result: cleaner numbers, stronger compliance, and clearer decisions to grow with confidence.
