Andrew Mate F.C.A.

Andy qualified as a Chartered Accountant in 1985. After qualifying he developed his skills working as a client portfolio manager with a provincial Firm. He gained his practising certificate in 1988 and shortly after set about developing his own practice. In late 1989 he and Michael joined forces to create Platt Rushton. 

After further study in the 90’s Andy passed the ICAEW’s financial advisors certification, and in 1997 became a Fellow. He is authorised by the ICAEW for Audit work.  

Over the last two decades Andy has been instrumental in driving the practise from a small general practices, to one of the leading firms of Chartered Accountants in the area.  

Alongside his general portfolio work Andy specialises in large corporate, and high net worth private clients. He is fully conversant with the complex commercial, financial and legal and tax issues facing them. He is equally at home in the boardroom, as sitting researching a piece of international tax law.

In addition to day to day audit accounts and tax assignments Andy routinely deals with complex tax work, group structuring, acquisition & mergers, corporate finance and UK and international consulting assignments.  

Andy also deals with much of the practices Estate planning/Wealth management, and trust work. He also consults various legal and financial firms on land, property and agricultural transactions.

Andy professes to be a workaholic, but somehow finds time for his pastimes. In his youth he was a professional sailing instructor, and can at weekends often be found on the water apparently ‘getting his hours up’ for his yachtmasters ticket. In the winter Andy and his family have a love for Skiing. A pastime they have enjoyed together for the past 25 years. In between Andy is a keen golfer, and if he doesn’t answer the phone will be found on a golf course or in the garage tinkering with one of his car restoration projects.

Graham Powling A.C.A.
