The brokerage believes it is the first in the UK to be awarded the international standard.
Rob Killeen, business manager at Capital Fortune, said: “Even though the economic conditions have been challenging, we as a business have never lost sight of the business ethos of growth through service excellence.
“This has been reflected in the ISO 9001 certification and our commitment to quality in every aspect of our dealings with clients.
“The certification is not a short term award, it means Capital Fortune now has a set of quality standards which it can evaluate itself against.”
Killeen encouraged all intermediaries to regularly review their management systems to achieve the requirements of the standard.
The brokerage also announced an increase in year-on-year turnover of almost 250%.
