Standard Life has seen operating profit increase by 28 per cent to £161m thanks to a smooth RDR transition.
The firm said it had made a smooth transition to the RDR and 77 per cent of its wrap partners were using adviser charging.
There was a 10 per cent increase in adviser firms using the Standard Life wrap and a 41 per cent increase in those placing more than £20m in assets.
Standard Life was also dealing with 342 advisers it had not dealt with for several years who had returned to the firm post-RDR.

Paul Matthews, chief executive of UK & Europe Standard Life, said: "We were well prepared for the regulatory changes introduced over the last year in the UK and we're starting to see the results we anticipated. Our strategy and high-quality propositions continue to address the needs of our customers, advisers and employers, with increasing momentum in both our retail and corporate businesses.
"The RDR has played to the strengths of the advisers we do business with and we have also been able to open our doors to a broader range of advisers."
