The Dundee firm, which is based on Clepington Road, was founded in 1974 by Charles Robertson. As a result of the acquisition, his successors Nigel, James and Hannah Robertson will transfer to the GS Group.

Fellow director Alison Duncan plans to retire after facilitating a smooth handover of the business, The Courier reports. 

Nigel Robertson, who joined the business in 1980, said: “We felt the time was right to step back.” He added that acquisition would ensure clients would enjoy the same quality of service they have come to expect over the years.

Mr Robertson said: “We looked at a number of like-minded firms which would share our business ethos and commitment to our clients. We are delighted the GS Group more than matched our expectations.”

He reflected on the changes that have taken place in the insurance industry over the last four decades, he said: “The financial services industry has evolved. We have seen many changes in the types of products available.

“New names have entered the market, with familiar ones such as Commercial Union, General Accident and Norwich Union disappearing.”

He added that changes to legislation have given customers far greater financial protection. He said: “We have been at the forefront of these changes – making sure our clients have received the best in terms of service and the products and insurers we recommend.”

George Stubbs, founder and managing director of GS Group, commented: “The GS Group started more than 30 years ago and we remain proud of our independent status. The acquisition of such a respected firm as Strathtay Insurance Brokers will further strengthen our position in the Dundee and Angus market.

“We are delighted Nigel, James and Hannah will join us at City Quay and we wish Alison a long and happy retirement.”
