Meanwhile, gross margin at the agency grew by nearly 7% to just under £11 million.
Leigh Jagger, Banks Sadler Group CEO, said: "We are absolutely delighted to see another year of solid and sustainable growth. We are especially pleased that all our overseas offices are now contributing to this growth with the only obvious exception being our latest office opening in China, which only opened its doors in June last year."
She added that the company had anticipated a slower rate of growth in 2015, as several key clients went through merger and acquisition activity, resulting in restructuring programmes and a temporary slowdown in meeting and events activity.
"We are now starting to see those clients revisit their meeting requirements and have already seen an upturn in 2016. As a group, we have continued to invest in our event technology offering and creative production, as well as expand our senior team, so we are confident that we have very solid foundations in place for what is looking like a very positive 2016."
The continuing growth across the group has been driven by new client wins, as well as a number of existing global clients utilising the overseas office network.
