TES, formerly Terry’s Electrical Services was established in 1968 by Terry Jones. In 1995, four long term employees purchased the company from Terry and continued to expand and develop it into its present form today. With this new leadership team, TES has gone from strength to strength and is now one of the largest Mechanical Electrical companies in Australia with operations in Sydney, Brisbane and the Gold Coast, while completing major projects in Darwin, Mackay, Townsville and Adelaide.
