LEI Regulation Spotlight
Bank of England CHAPS ISO 20022 enhanced data
Understand how the Bank of England’s CHAPS payment system is undergoing a major modernisation as part of the UK move to ISO 20022 and enhanced financial crime controls, and how the LEI is at the heart of enabling a successful change.
Overview
In its policy statement published 22 September 2025, the Bank of England confirmed that from November 2027 it will expand the mandatory use of enhanced data fields in the CHAPS system (the UK’s high-value payment system) utilising the international message standard ISO 20022. This builds on CHAPS’s migration to ISO 20022 in June 2023 and follows earlier mandates for LEIs and purpose codes in certain CHAPS payments.Objectives and scope
- Drive global harmonisation of payment messaging and data standards to improve straight-through processing (STP), resilience and cost efficiency in the UK high-value payments market.
- Mandate “enhanced data” (including purpose codes and LEIs) in CHAPS payments initiated by Direct Participants (DPs) via payment channels under their control, from November 2027.
- Encourage downstream channels and third-party initiation to adopt enhanced data capabilities (though full mandatory coverage extends only to DP-controlled channels at present).
Why organisation identity matters
High-value payments, such as those processed through CHAPS, require precise, real-time identification of participating entities. Without unique legal entity identifiers, inconsistencies in naming, multiple local identifiers and cross-border counter-parties complicate screening, reconciliation and regulatory oversight. Embedding the LEI into ISO 20022 enhanced data flows ensures that payers, payees and intermediaries can reliably reference the same entity across systems, which in turn improves payment transparency, audit-trail completeness and supervisory monitoring.
- The policy states that CHAPS DPs have already been required since May 2025 to include LEIs in payments under defined criteria.
- From November 2027, the expanded requirement means that for all CHAPS payments (via DP‐controlled channels) the LEI and other enhanced data (purpose codes, structured remittance) must be provided, paving the way for richer entity-level data and enhanced analysis.
- For corporates and financial institutions initiating high-value UK payments, this means that internal systems should already capture, validate and deliver LEIs in payment messages, aligning with CHAPS requirements and facilitating interoperability with global payment flows.
Implementation insight
To align with Bank of England CHAPS ISO 20022 requirements:
Data audit
Financial institutions should audit their payment messaging capability to ensure ISO 20022 schemas support enhanced data fields (LEI, purpose codes, structured remittance) and that outbound/inbound processes capture and validate LEIs.
Schema readiness
Payment participants (both banks and corporate senders) should assess corporate entity-data management: ensure all entities involved in CHAPS payments have a valid LEI, and that any platform generating or receiving CHAPS messages includes the LEI in the designated field.
Channel alignment
Direct Participants should engage with payment initiation channels to ensure subcontractors or third-party initiators align with the November 2027 mandate (in channels under DP control) and prepare for future extension to other channels.
LEI maintenance
Corporate treasuries should treat LEI availability and renewal as core to message readiness: an expired or missing LEI may lead to payment rejections, delays or increased operational risk in the high-value payments environment.
RapidLEI support and next steps
RapidLEI delivers streamlined LEI registration, renewal and bulk LEI portfolio management, enabling institutions to meet the upcoming CHAPS enhanced-data demands with confidence.
- Register the LEIs of all legal entities involved in your CHAPS payment flows now, ensuring full timeliness and validity ahead of the 2027 deadline.
- Integrate RapidLEI’s validation API into your payment-messaging engine so LEIs are automatically verified and formatted correctly in ISO 20022 messages.
- Use RapidLEI’s renewal management to avoid lapses and reduce the risk of payment exceptions due to expired identifiers.
