Salford-headquartered investment platform AJ Bell's assets under administration surpassed £65bn for the first time during the second quarter of its financial year while the number of customers jumped by more than 30%.
The listed group has revealed that its total AUA increased to £65.2bn compared to last year and 4% in the quarter.
Total customer numbers also increased to 346,797, up 32% over the last year and 11% in the quarter, with total net inflows in the quarter of £1.5bn, up from £1.3bn.
The latest figures come after the group said at the end of March that its revenue for its current financial year is set to be at least £6m ahead of current market expectations.
Chief executive Andy Bell said: "The run up to the recent tax year-end was our busiest ever, driving strong growth in customer numbers and assets under administration during our second quarter.
"Our easy-to-use, low-cost platform continues to perform well in both the financial adviser and direct-to-consumer markets.
"Our adviser platform saw its largest ever quarterly increase in new customers. This is testimony to our award-winning proposition and the price advantage our customers enjoy compared to other major adviser platforms.
"Our direct-to-consumer platform saw record growth in customer numbers and inflows in the quarter. We continue to see growing numbers of younger people joining the platform as they look to take control of their long-term financial future via pensions and ISAs.
"Our new and existing customers continue to consolidate existing investments onto our platform, meaning we are growing quickly whilst maintaining a high average customer portfolio of £79,000.
"Our investment business also had another strong quarter, with both advisers and customers recognising the value and performance our low-cost investment solutions are delivering.
"Our managed portfolio service is growing increasingly popular with financial advisers and our range of multi-asset funds is seeing strong inflows, with our Responsible Growth fund proving particularly popular.
"Our assets under administration surpassed £65bn for the first time and momentum remains strong going into the second half of our financial year."
AJ Bell is expected to announce its full results for the six months ended March 31, 2021, on May 27.
The news comes after the business announced the acquisition of a group of companies which it hopes will enhance its mobile technology for advisers and its clients.
It also recently named Baroness Helena Morrissey as its new chair.
