The ISA that puts your money to work, without the fees

We believe our ISA is the best in the UK because it’s totally free to open or transfer an ISA at any time. You can add and withdraw money whenever you want, and we offer a broad but focused range of funds to invest in.

This Transfer Season, start or transfer with £20,000+ before 1 September 2025 and enjoy 10 years with no platform fees. T&Cs apply. We also refund the fund fees on more than 30 ETFs from managers including BlackRock, Fidelity, and Vanguard.

Capital at risk. Investments can go down as well as up.

Happy switcher

I've recently transferred my pensions from a legacy provider to Prosper and am very happy to have done so. Its mission to reduce the impact of platform fees for savers is commendable and in stark contrast to much of the wealth management industry. The platform is intuitive, low cost and when needed, the customer support team responds far quicker than the weeks-long lead time from my old legacy provider. Looking forward to seeing where the team takes the platform and pleased to be on that journey. Many thanks!

Great product

Great product, great prices and very easy to use. Why would you pay more for HL or A J Bell.

Zero fees!

Love the commitment to zero fees. Really easy to open multiple types of accounts (ISA, General, Fixed, Instant-Access, Pension etc). Simple to see where my money is, and what’s happening to it. Love how easy it is to choose a fund to use.

Stunning customer service

My first move on to Prosper App had a minor glitch but this was dealt with by the support function within the app. Rohan what a star!! The whole experience has been wonderful and I strongly recommend Prosper to all who want a no fuss investment platform which offers great products!! Big thank you to the Prosper team.
