Find out more about ring-fencing and how retail bank customers will be affected.

The Ring-fencing legislation requires each large UK bank to separate its retail banking activity from the rest of its business. This is to protect customers and the day-to-day banking services they rely on from unrelated risks elsewhere in the banking group and shocks affecting the wider financial system. 

It reduces the likelihood that essential banking services used by ordinary depositors, like current accounts, savings accounts and payments, are put at risk by a failure in another part of the business, such as investment banking.

Ring-fencing was one of several important reforms brought in by the government to strengthen the financial system following the financial crisis that began in 2007.

The large UK banks are required to implement ring-fencing as of 1 January 2019 (subject to applying for waivers on specific issues). 

Ring-fencing only affects the large UK banks

Ring-fencing legislation applies only to UK banks with a 3-year average of more than £25bn ‘core deposits’ (broadly from individuals and small to medium-sized businesses). 

It is these large banks that must ‘ring-fence’ or legally separate their essential banking services from the rest of their banking group.

Essential banking services are the core services that retail banks offer and include:

  • accepting deposits or other payments into an account
  • offering facilities for withdrawing money or making payments from an account
  • overdraft facilities

How retail bank customers will be affected

The changes required by the ring-fencing rules resulted in a number of the largest banks carrying out a restructuring to separate their retail banking activities.  This involved transfers of parts of the business to other parts of the group through a court process known as a ring-fencing transfer scheme.  All of the UK ring-fencing transfer scheme processes relating to ring-fencing are now complete.  There were also customers whose sort code needed to change as a result of the restructuring.  These changes are also now complete. 

As a result, at the date of this update, all UK customers should already have been contacted and all customer sort code changes will have been made.  If you receive a communication appearing to be from your bank relating to ring-fencing now you should be extremely cautious and consider the fraud protection messages below. 

If your sort code has been changed the banks expect payments sent to old account numbers and using old sort codes will be automatically redirected to their intended destination, for a significant period of time. 

Direct debits and many standing orders will be updated by the banks on the customer’s behalf.

Protect yourself from fraud 

If you are affected by changes as a result of ring-fencing, your bank should already have informed you.  All bank customers should remain alert to the possibility of banking and online account scams.

Steps you can take to protect yourself include: 

  • Treat all letters, phone calls, emails and text messages with caution. Don’t assume they are genuine if they claim to be from your bank. It is best to check with your bank using the number on your card or bank statement.
  • Do not give out your account or card details or make changes to payments unless you are certain who you are dealing with.
  • A genuine bank or organisation will not contact you out of the blue to ask for your PIN, full password or to move money to another account. Never give out your personal or financial details unless it is necessary to use a service that you have requested and given your consent to, and where you trust the provider.
  • Don’t be rushed or pressured into making a decision or acting quickly. A genuine bank or other organisation won’t mind waiting if you want time to think.

Regulation of ring-fencing

The Prudential Regulation Authority (PRA) is the lead regulator for ring-fencing. It is responsible for identifying which banks are within the scope of the ring-fencing legislation and for supervising banks’ implementation of the prudential rules. 

We are working with the PRA, the Bank of England, the Treasury and the larger UK banks to support the banks’ implementation of ring-fencing efficiently and on time. 

Further information

If you have any questions about ring-fencing or concerns about any communication you have received about it, you should contact your bank.

The Bank of England has a jargon-free explanation of ring-fencing. The Prudential Regulation Authority also has technical information about ring-fencing, which it calls ‘bank structural reform’.

HM Treasury has more on the legal background to ring-fencing.
