Nucleus, the investment platform group founded and part-owned by advisers, has said inflows in the first three quarters of 2014 totalled £1.5 billion, up 15 per cent on the same period last year.

The Edinburgh-based group said assets under administration at the end of the quarter stood at £7.5bn, up 25 per cent, while turnover rose by 25 per cent to £17.2m, and profit by a "significant" 46 per cent to £1.9m.

David Ferguson, chief executive, admitted that Nucleus's market-leading upgrade on to next generation technology in June had "not been without pain," but went on: "I'm proud that we've been able to retain our position as the second fastest-growing UK adviser platform, and the combination of established momentum, the impending changes to the retirement market, and the overdue ban on payments from fund managers to platforms, give us a lot to look forward to."

He said the recent appointments of Doug Heron as chief financial officer and Andrew Smith, former chief operating officer, as chief technology officer ensured Nucleus would enter 2015 in its strongest ever market position.
