The UK's Financial Conduct Authority, which regulates non-bank payment service providers under the Payment Services Regulations 2009 and Electronic Money Regulations 2011, has been working with HM Treasury to to develop rules for non-bank payment service providers to access the Bank of England's real-time gross settlement system.

The FCA will subject providers that apply for access to a supervisory assessment. The payment schemes and the Bank of England will review them first, however, before referral to the regulator. After acceptance, it will subject them to something it calls "on-going strengthened supervisory oversight."
