Bristol-based Jelf Group has acquired Reading-based Goss Group in a deal valued at more than £10m.
Jelf said the move would make it the dominant commercial insurance, corporate healthcare and employee benefits consultancy in the South of England and Wales.
The deal will give the combined operations a commercial insurance book worth more than £75m in annual premiums. While Jelf Corporate Healthcare will increase its premiums to £50m, and annual turnover will increase to above £10m.
Alex Alway, group chief executive of the Jelf Group, said: “Our increased scale will enable us to forge more meaningful strategic partnerships with suppliers and insurers, leading to greater value for our clients.
“I have no doubt this will be a successful venture and look forward to working side-by-side with our new colleagues.”
