How it works

How does Flagstone work?

Partnering with more than 40 banks and building societies, Flagstone offers clients a portfolio of 250+ savings accounts (instant, notice and fixed term), accessible through one single Flagstone account on our digital platform.

Clients open one single Flagstone account on our platform, choose and select from all available deposit accounts from multiple banks, spread their savings and move them between different accounts easily with just a few clicks.

Flagstone provides full control of your cash with 24/7 secure online access. 

How can Flagstone access competitive rates?

Due to the volume of deposits we intermediate and through the relationships we have developed with our partner banks, we are able to access exclusive and competitive deposit rates for Flagstone clients.

What fees does Flagstone charge?

Flagstone charges a one-off set-up fee of £500 for new clients opening an account on the platform with deposits over £250,000.

There is also an Annual Management Charge of between 0.15% p.a. and 0.25% p.a. dependent upon the value of deposits held by the client on the platform.

Where is my Flagstone account held?

When you transfer money to your Flagstone account, it is deposited into a ‘Hub Account’ provided by Barclays Bank Plc.

When a deposit account matures or a request for the return of instant access or notice account deposits is made, the funds are returned to the Hub Account.

Protecting your money

Is my money safe with Flagstone?

Ensuring the funds belonging to our clients are secure is our number one priority. As a company authorised and regulated by the Financial Conduct Authority (FCA), we are required to hold appropriate levels of regulatory capital and generally organise and manage our business to the high standards set by the FCA.

Flagstone partners with top tier technology providers and security experts to ensure the end to end security. We employ practices and techniques to keep our platform up to date with the ever-changing security landscape and to provide a secure platform to our clients.

Flagstone has adopted internal systems and controls designed to protect client funds from the risk of fraud. These include relevant IT controls, appropriate segregation of duties, restricted access rights and signature protocols.

Importantly, Flagstone does not allow any third-party payments and will only ever authorise payments from a client’s Flagstone Hub Account to their Nominated Return Account.

Do I have FSCS protection with deposits I made through Flagstone?

Yes. In the event that one of the banks on the platform were to go into administration, assuming the bank in question was a member of the Financial Services Compensation Scheme (FSCS), then our client (if eligible) would have a single claim under the FSCS limited to the deposit compensation limit of £85,000.¹

Equivalent compensation rules would apply for any EU Bank on the platform going into administration, under the deposit protection arrangements in their “home” EU member state.

¹FSCS deposit protection is £85,000 per depositor (£170,000 for joint accounts) per bank (as at 27 May 2020). For more information please refer to https://www.fscs.org.uk

What would happen if Flagstone went into liquidation?

Flagstone implements safeguarding measures to protect customer funds.

All funds held by Flagstone on behalf of clients are separated from Flagstone’s own funds and only held in designated trust accounts.

Furthermore, each client’s individual deposits are held against a unique alphanumeric reference number.

Were Flagstone to be placed in administration or wound up, clients retain full beneficial ownership of their funds at all times and as such these will be paid back to the client by the administrator. Clients have no credit exposure to Flagstone.


Hub Account

The Hub Account is a segregated trust account set up to receive the initial monies transferred by the client on to the Flagstone platform before they are sent on to a deposit account. It is provided by Barclays Bank Plc.

Furthermore, the Hub Account acts as the account to which all monies (principal and interest) must be returned by the relevant Flagstone banking partner at a maturity event or when they are requested back by a client in respect of an instant access or notice account.

Nominated Return Account

The Nominated Return Account is the existing bank account through which the transfers to or from Flagstone will be made.

The Nominated Return Account is set up based on the account information provided in the initial application form.

Unique Reference Code

The unique 'Reference Code' is provided with the Hub Account details under 'Add Funds' section.

When transferring money from your Nominated Bank Account, the unique 'Reference Code' should be provided along with account details for Flagstone to process your transfers.  

Instant Access Account

With an Instant Access account, the funds remain in  the account indefinitely until you provide Flagstone with notice that you want to return the funds to your Hub Account.

On receipt of your instruction, Flagstone will instruct the bank to return the funds to your Hub Account.

Once the funds are back in your Hub Account, Flagstone will send you a confirmation by email.

Notice Account

With a Notice Account, the funds remain in the account indefinitely until you provide Flagstone with notice that you want to return the funds to your Hub Account. 

On receipt of your instruction, Flagstone will give notice to the bank and the notice period will start (e.g. 120 days for a 120 day notice account).

When the notice period expires, funds will automatically be returned to your Hub Account. 

Once the funds are back in your Hub Account, Flagstone will send you a confirmation by email.

Term Account

A Term Account has a specific term (e.g. 3 months, 12 months etc.)

Once a Term Account is opened and funded, it cannot be broken until the end of the term.

This means that your cash is locked up in the account for the full length of the term, after which it automatically returns to your Hub Account.
