The UK payment schemes
Information on the UK’s payment schemes can be found in An Introduction to the UK Interbank Payment
Schemes.
In summary, non-bank PSPs may want to use one or more of the following schemes:
CHAPS – the UK’s same day payment system used for wholesale and time-sensitive retail payments.
Faster Payments (FPS) – provides real time payments 24/7 and is used for standing orders, single
immediate payments, forward dated payments, return payments, such as for internet and
telephone banking payments as well as mobile payments (e.g. through Paym).
Bacs – the ‘automated clearing house’, which processes Direct Debits and Bacs Direct Credits across
a three working day cycle.
Image Clearing System – Cheque imaging is the process that enables images of cheques to be
exchanged between banks and building societies, through the Image Clearing System, for clearing
and payment.
CHAPS is operated by the Bank, while FPS, Bacs and the Image Clearing System are operated by Pay.UK.
Payment schemes require a settlement service provider (SSP) to provide final settlement of the various
payment flows between the direct participants of a payment scheme. For these payment schemes, the
Bank is the SSP, providing settlement via a transfer of funds between settlement accounts held by
participants in the Bank’s Real Time Gross Settlement (RTGS) system. The Bank offers settlement
services in order to promote both monetary and financial stability, as settlement at a central bank
mitigates credit and disruption risk for the participants as well as end-users of the payment schemes.
CHAPS settles each transaction individually, in gross and in real-time across settlement accounts. In the
Deferred Net Settlement (DNS) payment schemes (Bacs, FPS, and the Image Clearing System), end-users
make payments during a ‘clearing cycle’ and payment settlement occurs at the end of this cycle. The
payment scheme calculates the amount each participant owes/is owed as a result of transactions made
during each cycle. This is sent to the Bank, which then simultaneously debits or credits each settlement
account this amount.
Note: The Bank also provides net settlement services to the LINK ATM Scheme and Visa Europe. While
LINK is covered in An Introduction to the UK Interbank Payment Schemes, neither it nor Visa are further
covered in this guide for non-bank PSPs. The required supporting regulatory and legal arrangements are
not currently in place to support settlement in these systems.
How have non-bank payment service providers accessed the payment
schemes previously?
In the past, non-bank PSPs were only able to participate in these payment schemes as a directly
connected non-settling participant or as an indirect participant. This type of indirect participation is still
available to non-bank PSPs as a participation option.
Directly connected non-settling participants have a direct connection to the payment scheme’s central
infrastructure where they can submit and receive payment messages, scheme messages and transaction
reports. However, they use a sponsor bank (an existing direct settling participant) to settle on their
behalf, using the sponsor’s settlement account at the Bank. Directly connected non-settling participation
is not available in CHAPS.
