We at the Travel Visa Company Limited and subsidiary companies are delighted to have been associated with Simon Lea and his team for over twelve years in which time their professionalism and support have been exceptional.

Ray Ward & Karen Taylor, Joint Managing Directors, The Travel Visa Company Ltd


Sigma Partners have been a true partner to me since 2000. Our relationship started with their payroll services. I was then employed by a German company, but under an English contract of employment, based in UK. The management of Sigma Partners was instrumental in advising me when I set up my first UK company in 2004. Under the guidance of Sigma Partners, the business we started 2004 acquired another company in 2006. SP’s management team accompanied me all the way, participated in all negotiations, carried out due diligence and supported our efforts to reach the right conclusions in an exemplary way. Since then, Simon Lea, Senior Partner in Sigma Partners, has supported the business expanding from a £300k p.a. base to £2,600k p.a. with advice, ideas and tools. Our relationship goes far beyond routine. His companionship during the last decade has helped to solidify our relationships with financiers and banks and our average growth rate of 24% would not have been sustainable without Simon’s support. It is refreshing to work with a firm of accountants who live their mission statement every day.

I have used Sigma Partners as my Accountants for over 16 years and have been very fortunate to have had Paul Sheppard and Chris Rebbetts looking after my Accounts (both Privately and Professionally). During this time I have found the firm to be personable, reliable, efficient and extremely knowledgeable. We look forward to many more years working with Sigma Partners.

Paul Sheppard, one of the main partners at Sigma, has been the bookkeeper for Bartlett Davis Communications for the last six years. We are a SME advertising agency based in Surrey. His work is always applauded by our accountants, who have little to do to finalise our annual accounts after Paul has submitted them and his work is always presented to a consistent high standard. We rely on Paul for everyday advice which he gives with authority and charm, and he is always up to date in his knowledge of legislation and changes to tax and company laws. On a personal note he is a pleasure to have in the office and is considered by us all as an integral member of the team. I would have no hesitation in recommending Paul Sheppard to anyone.
