Isio revenues hit £170 million in latest financial year

As Isio celebrates its fifth anniversary in business, the firm has announced double-digit revenue growth for its 2024 financial year. Leading to September, the group saw total income hit £170 million.
Wealth and investment advisory Isio started life as a carve out from a Big Four firm, having gained independence from KPMGin early 2020. This meant even as a new company, the firm started out larger than most independent firms – with more than 1,000 clients, ranging from mid-sized companies to FTSE 100s.
In the four years since it’s Exponent-backed separation, Isio has sought to rapidly build on this early momentum. This has included a number of acquisitions. In mid-2024, it secured fuel for further expansion, with a significant investment from Aqualine.
Now, the firm’s latest financial results have shown that these additions have paid dividends in a big way. Announcing its financial results for the year to the end of September 2024, Isio revealed that consolidated revenue had risen to £170 million, a 26% increase on the £150 million the year before.
Andrew Coles, chief executive of Isio, said, “We are five years into a strong growth journey. Launching on the eve of the pandemic we had to learn to adapt fast and I’m pleased to say we met that challenge and every challenge since. We have always been determined to do things differently and that approach has yielded great success, of which these results are just the latest evidence. As we grow, we continue to diversify, serving new clients and markets.”
Isio employs more than 1,200 people across 10 UK offices. Recently it announced the completion of the acquisition of K3 Advisory, as of February 2025, and is looking to continue to disrupt traditional providers with a bold and innovative approach, creating an entrepreneurial culture where its teams are empowered to deliver new ideas and solutions to the challenges its clients face.
Coles added, “I would like to thank all Isio colleagues and clients for joining us on our growth journey and look forward to working closely with Aquiline to build on this success for the future.”
