The migration to using the ISO 20022 messaging standard for UK payments is underway. We expect the first phase to happen in 2022. Start to get your organisation ready now.

The CHAPS ISO 20022 like-for-like and enhanced message schemas (version 1.0.0), Technical Guidance and Change Log are now available on the SWIFT MyStandards portal. MyStandards is a global repository for standards operated by SWIFT. Users must first register for a free account with SWIFT and then request to join the Bank of England’s ISO 20022 community. MyStandards can be found on the SWIFT website.
The Bank will also publish the schemas on Pay.UK’s Standards Source in due course.
Alongside these, the Bank has published the: CHAPS & RTGS ISO 20022 migration: revised approach and final schemas. This provides a new baseline for all ISO 20022 related documentation and should help guide CHAPS Direct Participants, Reserves and Settlements Account Holders, and related stakeholders with their migration to ISO 20022.
The document provides further detail regarding the Bank’s ISO 20022 migration approach and timelines, together with supporting information about the ISO 20022 messages, including the Bank’s initial Change Management Framework for the schemas.
On 14 September 2021 a Memorandum of Understanding was agreed with CHAPS Direct Participants for the handling of Enhanced Data during an Interim Period between November 2022 to February 2023. This has been facilitated by the Bank and developed by Direct Participants.
The global transition to the ISO 20022 messaging standard in payments will entail a short period of time during which GBP-denominated customer payment messages containing enhanced data may be subject to data truncation when transmitted via CHAPS. This is because there is a period that the SWIFT correspondent banking network will enable enhanced and additional data before the CHAPS system is able to carry this data.
More information is available in the Memorandum of Understanding, White Label Communications and Technical Guidance.
The Bank has published its migration approach of non-payment messages to the ISO 20022 messaging standard for CHAPS Direct Participants.
The document linked below provides further detail and supporting information about the approach of non-payment messages to the ISO 20022 messaging standard.
As part of the global transition to the ISO 20022 messaging standard, the Bank of England as operator of CHAPS, and Pay.UK as developer of the New Payments Architecture, are working together to align the UK’s transition approach to the new standard.
Payment users will be able to include a Purpose Code as part of the CHAPS messages they send following the implementation of enhanced ISO 20022 payment messages in February 2023. To help facilitate their introduction, both organisations are collaborating to develop a single joint list of Purpose Codes recommended for use across CHAPS and New Payment Architecture (NPA) payment systems. This consultation response summarises industry feedback to the consultation, provides the final recommended UK Purpose Code list, and expands on the Bank’s approach to implementing the list in CHAPS.
For more information on introducing Purpose Codes and transition to ISO 20022 messaging more generally, see our Policy Statement and ISO 20022 webpage, and Pay.UK's consultation and consultation response and next steps.
The Bank detailed its approach to developing Market Guidance for specific use cases in its December Policy Statement.
On 14 April 2021, the Bank published the first in a series of Market Guides: Implementing ISO 20022 messaging in CHAPS covering property payments. This guidance document have been commissioned independently on-behalf of the Bank, based on conversations with industry over previous recent months. The Bank will continue working with industry stakeholders to define market best practice guidance for implementing the ISO messaging standard in order to realise the benefits of the enhanced data.
We have launched the SWIFT MyStandards Readiness Portal to help you to start testing your CHAPS payment messages against the published schemas.
We encourage all CHAPS direct participants to use the portal to prepare for the CHAPS ISO 20022 migration.
We will monitor usage to keep informed of how ready the industry is for migration.
The portal will validate CHAPS ISO 20022 messages to ensure they comply with the schemas and the format meets mandatory requirements for a payment message to settle in RTGS.
It will also enable you to validate examples of the cash management and administration messages that CHAPS direct participants will receive from RTGS. This will enable them to prepare their systems to process them.
It links with the SWIFT MyStandards documents, not the Standards Source documentation.
To get access, you:
We are developing a set of use cases to support testing and we will shared these with direct participants via the RTGS Renewal Testing Working Group.
You can use portal in any way that supports your development of your CHAPS ISO 20022 messages.
The portal will be available throughout the RTGS Renewal Programme.
We will update it later in 2020 with the schemas for the enhanced CHAPS ISO 20022 messages.
