James Walker

James’ clients range from structures holding long standing family wealth to individuals who have created their own wealth or are in the process of doing so. The fun in the role for James is to build a long term relationship with his clients so it feels less like a professional relationship and more like a close personal one because, at the heart of it, James’ advice is focussed on what ultimately allows his clients and their family comfort and freedom, their personal wealth.

James joined us in October 2019 as a Private Client and Trust tax partner having previously headed up a Private Client practice in a similar sized London based firm. James’ ‘offshore’ expertise came through 10 years working in the Channel Islands for specialist UK tax teams within two of their largest fiduciary services providers.

James has played many sports over the years, and will do so once again, but his time is currently spent reading stories to, playing with, tidying up after and generally enjoying time with his young son and daughter.

Ian Cliffe

In addition to being a general practice partner offering general business and financial advice to his diverse client base, Ian also provides specialist corporate finance services including helping business implement their strategic growth and exit planning, financial and tax due diligence assignments, capital markets work including deal structuring/advisory and reporting accountants work on Standard, AIM and Aquis markets.

Having joined the firm in 1992 from university, Ian became ACA and CF qualified and progressed through the firm to become a partner in 2001. Since then, he has developed his client base and specialisms, also carried out a number of managerial roles including heading up the audit division, being part of the firm’s management including being managing partner from 2013 to 2019. The experience obtained from running the firm has been invaluable in developing Ian’s commercial and business skills that he can apply to client situations in his day to day advisory capacity.

Outside haysmacintyre and family life, Ian enjoys cycling, walking, generally keeping active and exploring new places and experiencing new activities. Both business wise and personally, travel has also been a great enjoyment – something that will also feature high on Ian’s plans over the coming years.
