The firm posted overall fee income of £174m for the year ended in August 2017, an increase from £160m one year earlier.
Meanwhile, its operating profit rose 3% to £32m.
Mazars’ six consecutive year of growth was led by a strong performance across all its services lines, but in particular in its financial advisory, accounting and outsourcing arm, which grew 23%, and its financial planning service, which grew 18%.
Phil Verity, Mazars UK senior partner, said, “I am proud that we have achieved another year of consistent growth and profitability. Our growth has been sustainable and provides an excellent foundation for the next three years.
“Looking ahead, we will continue to invest in our business to achieve further long-term sustainable growth.”
In December, Mazars announced it had acquired RCL consultancy for an undisclosed sum from retirement solution provider Embark group.
Mazars also published its global results on Friday, where it unveiled the group’s income increased by 12.5% to €1.5bn.
