Cofunds maintained the top spot on the The Platforum assets under administration leaderboard in the first quarter of 2013 as its AUA grew 10 per cent.
The L&G-owned platform saw AUA rise from £47.72bn in the final quarter of 2012 to £52.28bn in Q1.
Skandia retains second place, having increased assets by 7 per cent to £44.88bn, up from £42bn in the previous quarter.

Standard increased its assets by 12 per cent to £16.2bn, up from £14.4bn in Q4 last year.
Fifth-placed James Hay’s assets rose 4 per cent from £14bn to £14.5bn.
At the beginning of Q3 last year, James Hay moved all its Sipp business onto the platform, which saw its assets under administration jump from £800m at the end of 2011 to £14bn.
Transact lies in sixth place after increasing AUA by 9 per cent to £13.5bn, up from £12.44bn.
Aviva Wrap had the biggest percentage increase as assets rose 25 per cent to £1.57bn, up from £1.26bn. Parmenion increased AUA by 20 per cent to £600m from £500m, while Novia increased its wrap assets by 19 per cent from £1.42bn to £1.69bn.
Total platform assets increased 9 per cent to £244bn.
The Platforum head of adviser platforms Freddie Findlater says: “We have seen some impressive growth across the board this quarter in terms of AUA, so it would seem wrong to suggest that platforms that rely on IFAs are struggling to build assets in the short-term.
“Whilst some of this strong performance can be attributed to a good quarter for the FTSE, the data on net sales we have received so far suggest this has been a bumper quarter for many groups.”
