Carol Rudge

I lead the NFP group at HW Fisher and am Head of Coaching. I have worked in the sector for 30 years having followed my passion to become a specialist in this area not long after qualifying as a chartered accountant.

My experience extends across charities, universities, independent schools, trade unions and membership bodies and I have worked with a very diverse range of clients in terms of both size and activities. This has enabled me to develop significant expertise across all aspects of accounting, assurance and governance as well as strategic issues and risk.

I am a member of the Charity Commission’s SORP committee which gives me first-hand knowledge of the technical direction of travel for the sector. I have also been a member of an audit committee of a large international charity.

I am an accredited coach and really enjoy my coaching activities as I strongly believe that coaching can make a real difference to individuals. I am also a passionate believer in EDI.

I joined HW Fisher as a partner in 2021 having previously been a partner and global head of Not for Profit at Grant Thornton for many years.

Mark Powell

I am a Partner in the Bath office, I joined the team after eight years at Moore South West. I provide audit, accountancy and business advisory services to a variety of clients across a wide range of sectors, although I specialise in financial reporting, acting for clients reporting under both IFRS or UK GAAP including AIM listed clients, subsidiaries of foreign companies, and owner managed businesses. In addition to this, I work with a portfolio of not-for-profit entities including both charities and education clients, namely academy schools and further education colleges. I have a passion for helping people that want to grow their businesses achieve their personal and professional goals.
My background
Before joining Moore South West, I spent two years at a leading audit, tax, and consulting adviser, also Bath-based, prior to which I worked as an audit manager for PwC for ten years, including a three-year secondment to their Perth office. A world away from audit, in a former life I was a professional cricketer for Northamptonshire for six years where my claim to fame was being 12th man for England in a test match at Lord's; it was the debut of England’s leading wicket-taker, Jimmy Anderson. Outside of work, when I'm not taking my two children to their various sporting fixtures and clubs, I like to run, watch sport and try to stay on top of the gardening.
