Evelyn Partners had net new asset inflows increase by 6.2% in the third quarter, despite assets under management and advice dropping from £56bn last year to £52bn.
The firm's group operating income reached £151.7m in Q3, up from £140.4m in the same period last year, which it attributed to "continued growth in both Financial Services and Professional Services".
Chris Woodhouse, group chief executive of the firm, argued that the growth in the two services demonstrated the "resilience of our unique business model, and the importance of our role as trusted adviser to both our private and business clients".
Altogether, the annualised organic growth rate of gross new money reached 10% in the last three months for the firm, with 4% growth in net new money.
Woodhouse also highlighted the "challenging macroeconomic environment" for Evelyn, but argued that it had "delivered a robust performance" throughout the quarter.
He concluded: "Sound financial advice is particularly highly valued in difficult macroeconomic conditions, and we continue to guide our clients through this period of uncertainty.
"As a firm, we are continuing to invest in growing the business and believe that the breadth of our offering and the calibre of our team positions us well for the future."
