Exploring the new CAF Charity Deposit Platform – powered by Flagstone
All you need to know about what’s changed, and why.

Though we’re changing our model, we’ll still receive the same percentage you currently pay in fees (in line with what’s in your Engagement Letter). All that’s changed is the way we receive it.
Our maximum share of interest will depend on the value of your Flagstone portfolio, as shown in the table (on the right).
We’ll apply our share of interest to any new savings account you open, as soon as the bank confirms your first deposit. We calculate our share based on the total value of your Flagstone portfolio, on the day the bank confirms your deposit.
Understanding Flagstone’s new fee model
First thing’s first – you won’t pay more to access the new Flagstone platform.
Click 'Learn more' to explore the new model in more detail.
This share will be the same percentage you currently pay in management fees. We'll deduct it before we feature any savings account on our platform – so the rate you see will always be the rate you receive.
For each savings account you open through Flagstone, we’ll receive a small share of the interest paid by the bank in question. This will replace your annual management fee.
The model under
the microscope
Say one of our partner banks wants to add a new savings account to our platform. The Gross interest rate on that account is 4.00%.
Flagstone receives 0.25%
You receive a net rate of 3.75% (4.00% minus 0.25%)
If you previously paid 0.25% in management fees, then our maximum share of interest will be 0.25%. But it may be lower for certain savings accounts.
*Lower management fees apply to portfolio values above £1m.
Here’s a quick example, assuming a current management fee of 0.25%*.

Until now, we’ve always held a portion of your funds in reserve to cover your management fees. This cash sat idle – never earning you interest.
But now you won’t pay annual management fees, so there’s no need for the reserve. That means you can deposit all your funds, earn interest on every penny, and maximise your returns with the new model.
We'll also return what's left of your existing fee reserve to you. You can use this to top up any of your existing savings accounts.

The new platform: what to expect
Beyond a new fee model, there are some key differences to note in the new platform. We’ve covered them here in full.
The new platform uses a new holding account, provided by HSBC. You’ll find your new holding account details in the ‘Add funds’ section of the platform.
Please make sure you use the new HSBC details. We’ll need to return any payments you make to the old holding account, and you might miss out on interest earnings.
Because the new holding account is with HSBC, this may affect your FSCS coverage, depending on your eligibility and any other deposits you may hold with them. Please review your savings portfolio to make sure you’re fully protected.
Your new holding account details
When you first log in to the new platform, you may notice that certain features are temporarily unavailable. This includes the ability to see:

We’ve made some adjustments how you’ll navigate through the new platform. Here’s what’s moved, and where you’ll find it.

With our new platform’s ‘rollover’ functionality, you can select your next savings account in advance. Then, when the term ends on an existing Fixed Term savings account, we’ll transfer your funds automatically.
This way, you can eliminate any pauses in interest. So your cash stays growing, always.
You can arrange a rollover seven days prior to when your Fixed Term account matures. We’ll always email you when any Fixed Term savings account is approaching maturity.

Flagstone was recently recognised by the Sunday Times as the UK's 56th fastest-growing private company. We’re glad to be growing, and proud to be trusted by over 600,000 clients. But we’ve now outgrown our previous platform, which was stopping us launching new, powerful features.
By pausing certain features, we could move you to our new platform faster. Soon, we’ll restore those features you know, while also building new functionality. It’s one step back, for innumerable steps forward.
You can still deposit, withdraw, and manage your cash in Flagstone as normal.
Your account settings
Previously, you’ll have seen an ‘Admin’ tab in the platform. From here, you could amend your personal details, your security settings, and view your nominated account details. In the new platform, you can access these options by clicking your initials in the top right-hand corner, and clicking ‘Account settings’.
Your statements used to sit in the ‘Admin’ tab. But now, you can access them directly from the ‘Statements’ tab in the primary navigation bar.

While our Share of Interest model will apply – so the rates you see in the platform will drop slightly – our share on these accounts will match the rate you previously paid in fees. So, in effect, there will be no change.
What about your existing savings accounts?
If you have savings accounts open with Flagstone, you won't pay any more for them under the new model.
