Axa Wealth recorded a 45% rise in assets under management at its Elevate platform in the third quarter of the year, helping the group push its overall assets toward £25bn.
Elevate grew assets from £4.8bn in Q3 2012 to £6.9bn in the same period this year, thanks in part to £1.5bn worth of new sales.
The group said three quarters of all inflows in September went into 'clean' share class funds.
Elsewhere, Axa Wealth saw its investment hub Architas grow assets by 12% to £12.6bn over the same time period, while assets in its Corporate Investment Services proposition were up 35% to £3.7bn.
The growth helped Axa Wealth increase its overall assets by 18%, from £20.8bn to £24.6bn.
Axa Wealth CEO Mike Kellard (pictured) said: "I believe Axa Wealth is reaping the rewards of positioning itself successfully for the future, having been trading in an RDR (Retail Distribution Review)-friendly manner for many years now. Indeed, we have been offering fee-based products years before it became a regulatory requirement to do so.
"The heritage of our business was formed on the principle of a clear and transparent customer-friendly suite of products."
