Gross inflows of £1.1bn during the first quarter were up from £662m in the same period of 2015.
This was largely due to a significant increase in institutional new business with a number of new clients being added, the company said.
The Ascentric wrap platform saw sales of £0.5bn, down slightly from £0.6bn last year. Assets under administration on the platform increased by 3% over the quarter to £10.4bn from £10.1bn at 31 December 2015.
As a whole the Royal London group increased its funds under management to £87.9bn at 31 March 2016, up 4% over the quarter from the £84.5bn recorded at 31 December.
