Meanwhile employee benefits plus life and health insurance retail broking accounted for £41bn ($55.8bn), reinsurance broking secured £6.1bn ($8.3bn) and £10.8bn ($14.7bn) was attributed to wholesale broking.
Revenues from reinsurance and wholesale broking grew most quickly during the year, while those from employee benefits plus life and health insurance retail broking recorded the least growth, Insuramore said.
