The privately-owned firm has reported figures for its 2008/9 financial year.
Kadence said that 97% of existing UK clients commissioned research in the last 12 months, and added that four of its key clients -- Accenture, Nestlé, Nokia and Novartis -- increased their research spend by over 150%.
The UK office has increased its headcount in the last year from 21 to 28, and is looking to recruit a further five researchers.
Kieron Mathews, UK managing director of Kadence International, said: "The team has worked hard over recent years to build a sustainable client base through the delivery of creative and engaging research projects which provide quality findings, and it is thanks to these efforts that we have enjoyed yet another year of growth."
Kadence also has offices in the US, India, Malaysia, Singapore, Indonesia and China.
End of year figures for the Kadence International Group will be released next month, which will detail the performance of its global operations.
In February it reported a 40% increase in revenues to $7.8m (£5.4m) for the six months to the end of December 2008, with the strongest growth coming from developing markets in the Asia-Pacific region.
