After his early career in aerospace and nuclear energy, Geoffrey entered private practice in association with the late Leslie Heap and Gerald Lewis of Heap and Digby, Consulting Engineers, in 1969. While with them he designed water and sewage equipment and also the bascule moving machinery for the Lowestoft Bridge, in Suffolk. He practiced also as Beresford Hartwell and Associates and, in 1971 established a separate office in Wallington, South London.

In parallel with his design career, Geoffrey was first appointed as arbitrator in 1972 and his first foreign arbitration, an ICC appointment in Switzerland, took place later that year. He studied Law to Intermediate level and then transferred to the examinations of the Institute of Arbitrators (now Chartered) of which he became Chairman in 1996-1997 and for whom he taught in various countries on several courses, including the prestigious Diploma in International Commercial Arbitration.
