Our client's satisfaction is our priority

Overseas Service Agency S.A. was founded in Lima 1961 by a Dutch average agent. It started offering surveying and adjusting services to insurance interests outside Peru. By 1965 he was joined by another Dutch fellow and by Ronald Grant, an Englishman born in Liverpool, who after working with one of the largest shipping agencies, decided to accept a two-year working contract with Lloyd’s Agency Lima office in 1954, and stayed for 45 years.


There had been little P&I activity in Peru and what there was had been handled by Lloyd’s Agents, who held the appointment of Correspondents to several Clubs. However, it was realized by many Clubs that, if an alternative was available, it would be good to have a Correspondent not involved with cargo underwriters. Thus in 1966, Overseas Service Agency S.A., became West of England’s Peruvian P&I Correspondent, gradually being appointed by those Clubs not already committed. In the late 70’s it became a family group company; and by the 80’s it was Peruvian Correspondent to all P&I Clubs.
