Partners of every kind
We’re here to help everyone manage, protect, and grow their cash. And we work with a range of partners to do just that.
Why partner with Flagstone?
Market-leading bank panel
From high-street leaders like HSBC to established challengers like Allica, we work with more banks than any other savings platform. Which means unparalleled choice for our clients.


Trusted by UK institutions
We partner with some of the UK’s most established finance brands. St. James’s Place, Quilter, Money Supermarket and more. We know that talk is cheap – but trust is earned.
Flexible integrations
However you work, we’ll work alongside you. Whether it’s an API integration with our platform, a white-labelled version, or a more straightforward ‘referrer’ relationship.


Dedicated account management
Our partnerships are personal. You’ll receive a dedicated account manager to ensure your Flagstone journey is smooth and simple – through integration and beyond.
