Monzo is migrating its rapidly growing investment proposition to Seccl, the Octopus-owned platform, as it continues to expand its footprint in retail investing.
The digital bank, which now serves over 12 million customers, confirmed that more than 300,000 existing users with investment or pension accounts have been notified of the planned migration.
Seccl will take over the provision of custody, wrapper administration and investment services, while BlackRock will remain Monzo’s fund manager.
Monzo launched its investment service in September 2023, offering customers access to multi-asset funds through Stocks and Shares Isas and general investment accounts (Gias).
In July this year, the bank added a pension tracing and consolidation feature to its offering.
Monzo originally selected Seccl as its technology partner in January 2025.
Following successful integration, new investment accounts began running on Seccl’s infrastructure in May.
By early July, all new investment accounts were powered by the Seccl platform, with a full migration of existing customers scheduled for September.
As part of the move, Monzo is rolling out new features including a fully digital accumulation Sipp, allowing customers to make new contributions or consolidate existing pensions as well as the ability to invest in ETFs.
David Ferguson, CEO of Seccl, said: “Monzo has justifiably become one of the most well-known banks in the UK over the last decade. It has done what would have seemed impossible ten years ago — built a bank that people actually love.
“We’re thrilled to support Monzo as it extends its customer experience into investing.”
Andy Smart, chief product officer at Monzo, added: “In line with our mission to make money work for everyone, we’ve helped to demystify investing for thousands of customers. Working with Seccl means we can now introduce even more features and tools to help our customers grow their money, all within the Monzo app.”
Seccl is part of Octopus Group, which manages £12.5bn in assets across Octopus Energy, Octopus Investments and Octopus Money.
