CHAPS Access Requirements for Payment Firms

CHAPS — the Clearing House Automated Payment System — is the UK's high-value, same-day GBP payment scheme. Unlike Faster Payments, which operates as a 24/7 near-real-time system for retail and business payments up to £1,000,000, CHAPS is a real-time gross settlement (RTGS) system operated by the Bank of England, processing payments of any value (there is no upper limit) with irrevocable same-day finality. CHAPS is the essential payment mechanism for property transactions, large corporate settlements, financial market transactions, and any GBP payment where finality on the value date is non-negotiable. For payment firms with high-value payment needs, understanding the access requirements — and the realistic options — is fundamental to building a robust GBP payment capability.

CHAPS and the Bank of England

CHAPS moved from industry ownership to direct Bank of England operation in November 2017, following the Bank's designation as operator under the Banking Act 2009. The Bank operates CHAPS as part of its broader RTGS infrastructure, which also supports the settlement of other UK payment schemes, securities transactions, and central bank money transfers. The RTGS system processes final settlement in central bank money — the highest quality settlement asset — eliminating settlement risk between direct participants.

The Bank of England's role as CHAPS operator gives it a dual function: it is both the scheme operator setting access criteria and rules, and the settlement agent holding the settlement accounts used by direct participants. This dual role means that CHAPS access questions involve the Bank at multiple levels — regulatory eligibility, technical connectivity, and settlement account provision all flow through the Bank's infrastructure and oversight teams.

Direct CHAPS Access

Direct CHAPS participation requires holding a Sterling Monetary Framework (SMF) reserves account at the Bank of England and meeting the Bank's eligibility criteria for settlement account holders. The eligibility criteria focus on systemic risk: the Bank assesses whether an applicant's access to RTGS settlement would pose systemic risk, whether the applicant has sufficient financial resources and governance to meet its settlement obligations, and whether the applicant's operational capability meets the resilience standards required for a participant in critical national financial infrastructure.

Historically, direct RTGS access was limited to banks, building societies, and a small number of other systemically important financial institutions. The Bank of England's access review programme — driven partly by PSR policy objectives of widening access to payment infrastructure — has progressively extended eligibility to a broader range of entities, including some payment institutions and EMIs. However, the governance, financial strength, and operational resilience requirements remain demanding, and the application process is rigorous.

Technical requirements for direct CHAPS access include: connectivity to the RTGS system via the Bank's SWIFT-based messaging infrastructure (migrating to ISO 20022 MX messages as part of the RTGS Renewal Programme); compliance with CHAPS scheme rules, including processing obligations, intraday liquidity management requirements, and operational resilience standards; and the ability to send and receive CHAPS payments and manage the associated settlement account through a Bank-approved interface. The RTGS Renewal Programme — a multi-year infrastructure replacement project — is moving CHAPS to a new core settlement engine with enhanced ISO 20022 data capabilities, scheduled for progressive rollout through the mid-2020s.

Indirect CHAPS Access

Most payment institutions and EMIs access CHAPS indirectly through a direct participant — typically a clearing bank that holds a settlement account and processes CHAPS payments on behalf of sponsored clients. The indirect model for CHAPS operates similarly to FPS indirect access: the sponsored firm submits payment instructions to the direct participant, which initiates the CHAPS payment under its own RTGS membership and settles on behalf of the client.

CHAPS indirect access through a sponsoring bank carries concentration risk — the sponsored firm's CHAPS capability is contingent on the sponsor's own operational status and their continued willingness to maintain the arrangement. For payment firms handling high-value property transactions or financial market settlements, sponsor failure or termination of the arrangement creates acute operational risk: there is no alternative same-day mechanism for high-value GBP finality. Maintaining a secondary sponsor arrangement or an alternative high-value payment pathway is prudent risk management for firms with material CHAPS dependency.

CHAPS Fees and Economics

The Bank of England publishes a CHAPS fee schedule for direct participants. Fees are structured as a per-transaction charge (in the range of £0.15 to £0.25 per payment for direct participants processing at scale, subject to periodic review) plus an annual membership fee. For indirect participants, the effective cost per transaction is determined by the sponsor's commercial terms, which reflect the sponsor's own CHAPS costs plus a margin for the service. CHAPS per-transaction costs are low relative to the payment values involved — a £5 million property transaction attracting a £0.25 direct participant fee represents a negligible proportion of the transaction value.

The primary cost of CHAPS for direct participants is not the transaction fee but the liquidity cost of the intraday settlement account. Participants must maintain sufficient liquidity in their RTGS account to fund outgoing payments, and the Bank provides intraday repo facilities to help manage intraday liquidity peaks. The cost of maintaining these liquidity buffers — in terms of the capital tied up in the settlement account — is a more material consideration than the per-transaction fee for direct participants with significant CHAPS volumes.

CHAPS Use Cases for Payment Firms

For payment firms serving corporate clients, the key CHAPS use cases are: residential and commercial property transactions where the conveyancer requires same-day GBP finality; large B2B settlements where value-date certainty is contractually required; FX settlement for large spot transactions where the GBP leg must arrive in a specified account on a specific date; and treasury movements within corporate group structures. Payment firms that can offer CHAPS capability — through either direct access or a reliable indirect arrangement — provide a materially more comprehensive GBP payment service than those limited to Faster Payments for high-value flows.
