LONDON, Jan 26 (Reuters) - Fund manager Quilter saw a strong final quarter of 2021, with improved year-on-year net flows, it said on Wednesday.

Assets under management reached 111.8 billion pounds ($151 billion) at the end of December 2021, up 13% from the previous year.

The fund manager, which became a standalone company after the break-up of Anglo-South African financial services firm Old Mutual in 2018, saw year-to-date net inflows of 4 billion pounds and fourth quarter net inflows of 1 billion pounds.

"2021 was a year which highlighted the strength of our advice-based model," Quilter's chief executive Paul Feeney said. "We expect momentum to continue to improve in 2022," he added.

Quilter's new investment platform reported a sharp increase in gross flows to 9 billion pounds and net inflows of 3.5 billion pounds during 2021.
