For the year to end-September, funds under direction rose by 8.7%, which it said compared with a decline in the FTSE All-Share Index of 3.8% and a 2.8% gain in the MSCI World Index
Net inflows were £731mln over the past three months and £3.59bn for the year overall.
In a statement, Alex Scott, IntegraFin's chief executive said: "During the second half, the operating environment was difficult and unpredictable for us, for our clients, and for their advisers - and this seems likely to remain the case in the coming months.
“Nevertheless, and in no small part due to the resilience and dedication of all involved, I am pleased to report robust flows. Compared to our 2019 financial year, gross and net inflows held their own and we ended the year with our highest ever level of funds under direction.”
