Lucy Cohen
Co-founder, Mazuma
Built a subscription accounting business long before that was a normal thing to do, and talks candidly about the parts of founding a firm that usually go unsaid.
Most lists of "accounting influencers" are the same twenty-five American names recycled between directory sites that have never read any of them. This one is regional, deliberately short, and says what each person is actually good on.
Updated 2 August 2026 — reviewed annually.
The UK conversation is shaped by tax administration and digitalisation in a way no other market’s is, so the people worth following here skew towards policy literacy as much as practice management.
Listed alphabetically, not ranked — a league table of real people is a fight nobody needs.

Hudson Business Advice; author and speaker
Started, grew and sold her own practice, and now writes about that arc for people in the middle of it. Named one of the Top 50 Women in Accountancy and Finance. Particularly good on exit and on work-life boundaries.
Founder, AVN — The Accountants’ Network
Twenty-five years of research into what actually makes accounting practices more profitable, with an unusual focus on the effect a firm has on its owner rather than only on its numbers.
Past president, ICAEW
One of the most authoritative voices on UK tax administration and digitalisation, and a consistent critic of policy that looks fine in Whitehall and lands badly in a practice.
Chairman, d&t Chartered Accountants; author
Three business books with Hodder and a keynote circuit across the UK and Europe. Speaks to small business owners in language they use, which is a skill most of the profession lacks.
The Firm is published by the same people behind Vinyl and Journey, and Vinyl also sponsors coverage elsewhere on this site. They're listed here rather than in the list above, because a publisher ranking its own founders among independent voices isn't a ranking worth reading.
Co-founder, Vinyl
Works at the intersection of UK practice workflow and AI tooling, and writes for The Firm on where that is genuinely working versus where it is being oversold.
