Under this same ‘realistic’ scenario, Quilter is predicted to take the spot as the top adviser platform with £219.7bn in assets under administration by 2030, a 15% market share.
Nucleus is predicted to hold the second spot at £194.4bn in assets by 2030, but with a slight drop in market share to 13.3% (2025: 14.1% of total assets).

Bella Caridade-Ferreira, CEO of Fundscape, said the top three platforms are increasingly dominating the adviser platform market and this is set to continue.
She said: "The UK platform industry has stopped behaving like one industry. The leaders are running their own race, the laggards are running out of road, and the platforms in the middle are working out which way they need to go. The cost of backing the wrong platform has never been higher."
This is the first year where Fundscape’s annual report on adviser platforms has broken down longer term growth projections by individual platform. Previous forecasts have been industry-level.
