Our Team

Martin began his career in the London insurance market in 1970 as an aviation facultative broker with Lloyd’s broker C E Heath. In 1983 Martin moved to Guernsey to join Transglobe Underwriting Management (Guernsey) Limited and was then appointed Managing Director of Polygon in 1995, who were the majority capacity provider to Transglobe.

In 2001 Martin orchestrated the management buyout of the fee-based companies from Polygon which formed the basis for a new company, Heritage Group Limited.  In 2005 Martin also led the buyout of the Hiscox group’s shareholding of the Heritage Group and was instrumental in the Heritage Group’s expansion. During this time Martin was Chairman of Heritage Trust Company, Heritage Fund Admin, Heritage Insurance Brokers and Heritage Captive Management.  Martin then organised the sale and purchase of the airline founder’s shareholding in Polygon.

In 2008, Martin stepped down as Chief Executive Officer, moving to the role of Non-Executive Chairman of Heritage Group until 2014. Polygon then sold its shareholding in the Heritage Group and Martin purchased the rest of management's shareholding in Polygon, making the Polygon Collective a family office. Martin now focuses exclusively on the development of the Polygon Collective.

Polygon Collective has grown enormously since then and Polygon Serviced Offices are now the Channel Islands largest supplier of serviced offices and Polymetrix is the largest and most respected data and benefits survey company in the Channel Islands. With the re-branding of the Vantage companies to Polygon, we are a strong player as a pension trustee in Jersey and one of the fastest growing insurance brokers in the Channel Islands.

Martin also holds the chairmanship for the Guernsey Nature Commission and is a president of the Guernsey Rugby Club.
