Your very own portal
Think of your Flagstone referral portal as a control centre for your clients’ cash. See everything, every day, for every client.
No bank contact
Consolidated information
View all your clients’ savings accounts in one place, measure performance, and keep track of every pound. And get a single interest statement for their end-of-year taxes.
No banks will ever contact your client directly. So you can own the client relationship, guide their decisions, and track every action from your referral portal.
Complete control
Timely updates
Whether it’s a new leading rate or an upcoming maturity, we’ll always notify you by email when new rates arise. So you can stay informed, and plan accordingly.
Flagstone will never advise your clients, or make transactions on their behalf. The only voice that matters is yours.

How the Flagstone Cash ISA works

Neither Flagstone nor Wealth Kernel will ever have control over your clients’ cash – we hold their deposits in trust, so they’ll always be the sole owner. We’ll only ever move money at your clients’ request, on their behalf. They’re always in total control.
