Our Beginnings

Grosvenor-Engineering-Group-Beginnings
Grosvenor Engineering Group began with three university friends who had studied engineering at the University of New South Wales, two of which are still Owners / Directors today – Nicholas Lianos and Peter Souflias.

Nicholas came across Grosvenor Air Conditioning, a company looking to sell its HVAC maintenance contracts and with his university friends they bought the contracts. In May 1994, the Grosvenor Group of companies began with a team of 13. Today we are a national company with customers spanning across Australia.
