Old Mutual Wealth saw Q3 net inflows rise 33% year-on-year as government savings reforms began to take effect and the WealthSelect range gained traction.
The business saw net client cash flows of £800m over the quarter, up from £600m in Q3 2013, helping take total funds under management to £82.2bn by 30 September.
While gross and net sales at Old Mutual Global Investors (OMGI) were flat year-on-year, the UK platform enjoyed its strongest quarter of the year to date on a gross basis, with £1.3bn of gross flows.
Net flows to the platform stood at £500m, up from £400m a year previous, to help total platform assets to £29.5bn.
The most significant boost appears to have come via the business' WealthSelect proposition, launched earlier this year.
Old Mutual Wealth said flows into the range now stand at almost £500m since its launch earlier this year. With £225m of inflows as of 31 July, that indicates further inflows of over £250m between 1 August and 31 October - though the latter month fell outside the reporting period.
Increased ISA allowances and interest in drawdown retirement products also helped increase flows, according to the group, following the greater personal finance and pensions freedoms announced in this year's Budget.
The firm has also increased flows from its purchase of the Intrinsic network, with 6% of flows to the platform sourced from those advisers, compared to 3% in July.
Total AUM at OMGI, meanwhile, now stands at £17.4bn. Ian Heslop's Global Equity Absolute Return and North American Equity funds were among the group's most popular products on the quarter.
However, Stewart Cowley's Strategic Bond fund suffered outflows after a spell of underperformance, Old Mutual Wealth added.
Flows into the platform from OMGI were more than twice as high as in the same quarter in 2013, at £470m.
OMGI hopes to use the recent hiring of former Ignis managers Ian Ormiston and Russ Oxley, as well as that of ex-BlackRock manager Joshua Crabb, to strengthen its fund management capabilities.
It expects to add another £1bn of funds under management in the fourth quarter due to its purchase of the rest of the Cirilium business, in which Henderson Global Investors previously held a 50% stake.
