Learn more about Flagstone and our business account
What is Flagstone?

Flagstone is an online deposit account marketplace founded by two experienced ex-bankers in 2013.

Flagstone is revolutionising the UK’s savings market by delivering win-win outcomes for both clients and banks with its innovative online aggregator platform.

Flagstone, registered as Flagstone Group LTD, operates only in the UK and is authorised by the Financial Conduct Authority under the Payment Service Regulations 2017 for the provision of payment services.

What is the Flagstone platform?

Flagstone provides clients with a secure online platform which enables them to compare 200+ deposit accounts from over 30+ banks and open as many accounts as they require with just a few clicks. The platform also provides 24/7 reporting and consolidated statements for all accounts held with all banks for any time period.

Is Flagstone a bank?

No, Flagstone is not a bank. We are an online Fintech platform, providing access to hundreds of deposit accounts from over 30+ banks and building societies enabling our clients to maximise their interest income and conveniently increase the value of their deposits that are eligible for FSCS protection. FSCS covers £85,000 per depositor per authorised UK bank where eligible.

How does the Flagstone platform work for businesses?

Partnering with more than 30+ banks and building societies, Flagstone gives you access to more than 200 deposit accounts through a single application.

Using Flagstone's secure online platform, you can quickly and easily diversify your deposits with different UK banks and building societies to increase the total value of those deposits that are eligible for FSCS protection.

Ongoing access to exclusive and market-leading interest rates empowers you to maximise the interest income from your cash.

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.

How does Flagstone make money?

For each savings account you open through Flagstone, we receive a small share of the interest (up to 0.30%).

We deduct that share before we feature any savings account on our platform – so the rate you see will always be the rate you receive.

Where is my Flagstone account held?

When you transfer money to your Flagstone account, it is deposited into a ‘holding account’ provided by Barclays or HSBC Bank plc. The holding account is a segregated trust account set up to receive and hold funds before they are sent on to a deposit account. 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 holding account.

Does Flagstone choose the best accounts for my cash reserves?

No, using the online Flagstone platform you have full control of which banks you choose to deposit your money with and which accounts you open.

Can I split my business's cash reserves across multiple banks?

Through a single Flagstone account, you can use our secure online platform to open as many deposit accounts with as many different banks as you require, in just a matter of clicks.

You can complete all these transactions via our online and secure platform 24/7, without any further paperwork.

Will I have statements for tax returns?

Flagstone gives you visibility of every pound earned and the simplicity of consolidated reporting.

Once you have a Flagstone account, you will have 24/7 access to consolidated statements for all your deposit accounts for any period of time, available to view and download via the platform.

At the end of each tax year, Flagstone will provide you with a summary of interest earned.

If your payments do not quote your unique ‘Client Reference’, they may be returned to you.
Are my business's cash reserves secure 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 holding account to their nominated account.

Will any deposits I make through Flagstone be protected by the FSCS?

Yes. In the event that one of the banks on the platform, or the holding account bank (HSBC Bank plc), 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

¹FSCS deposit protection is £85,000 per depositor (£170,000 for joint accounts) per bank. 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.

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.

Holding account

The holding 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 holding 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 account

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

The nominated 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 holding account details under 'Add Funds' section.

When transferring money from your nominated 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 holding account.

On receipt of your instruction, Flagstone will instruct the bank to return the funds to your holding account.

Once the funds are back in your holding 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 holding 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 holding account. 

Once the funds are back in your holding 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 holding account.
