The Lang Cat has released data from its Analyser service, revealing the top 10 most popular platforms selected by advisers through the tool in 2025.

The top three platforms remained the same year-on-year, with Transact, Quilter, and AJ Bell Investcentre taking the top three spots, in that order.

Fundment traded places with Aviva Platform to rise to fourth place, while Aberdeen Wrap retained sixth spot and Fidelity Adviser Solutions rose one place to seventh.

Scottish Widows Platform was a new entry in eighth place, having come 19th in 2024, followed by Nucleus, which fell two spots, in ninth, and Aegon Retirement Choices in 10th, which was another new entry.

Parmenion and Aberdeen Elevate fell out of the top 10 between 2024 and 2025.

The Lang Cat also highlighted platform features of interest that firms are looking at as part of their due diligence processes.

Many of the features in the top 10 were hygiene due diligence options, such as the existence of SIPPs, ISAs, and GIAs.

Meanwhile, flexible ISAs were top of what The Lang Cat defined as the ‘decision-making zone’ of the list, while full straight through processing for ISAs also appeared to be important for selection.

Onshore bond sales reached record highs in 2025, climbing two spots into the top 20, while offshore bonds also rose two places.

“While the top three most popular platforms have remained the same as 2024, it’s interesting to see some movements from fourth place onwards,” said The Lang Cat senior analyst, Rich Mayor.

“In terms of features that make the most difference, a clear picture is revealed when you look beyond the more basic due diligence options into the decision-making zone.

“Regulatory and other market changes appear to be affecting advisers research with Junior ISAs, Full straight through processing on ISAs, good transfer times, target market and price all critical features.

“It’s reflective of a year where both advisers and platforms have worked to reduce friction in processing in order for both to become more efficient, and also broader changes in planning as a result of Budget and regulatory announcements.”
