What’s changing with CHAPS payments?
CHAPS (Clearing House Automated Payment System), the UK’s high-value payment infrastructure, is migrating to the ISO 20022 messaging standard. This shift introduces richer datasets, improved transparency, and greater global interoperability.
While the benefits are clear, the migration can be complex – requiring significant operational and technical change. Partnering with an expert like AccessPay ensures:
- Data transformation and enrichment support
- Minimal disruption to business operations
- Full ISO 20022 compliance across payment processes
What changes do I need to make?
1
Phase 1: Initial implementation (Up to April 2025)
ISO 20022 has been live in CHAPS since June 2023. During this phase, banks are gradually rolling out capabilities to their customers.
Global adoption is progressing, with European cross-border payments already utilising the new standard.
2
Phase 2: Monitored compliance until May 2025
Starting May 2025, non-compliance with the new standard will be monitored and followed up. Banks and organisations will be encouraged to transition to the new standard, but payments will not be rejected for non-compliance at this stage.
The Bank of England will closely monitor CHAPS participants’ usage of new data fields.
3
Phase 3: Mandatory transition period begins May 2025 – October 2026
This period overlaps with Phase 2, allowing banks and payment system users time to adapt their systems.
Compliance expectations will gradually increase, supported by ongoing communication and guidance from regulatory bodies and support from third parties like AccessPay.
4
Phase 4: Mandatory transition period begins May 2025 – October 2026
Beginning November 2026, non-compliant payments will be rejected. This applies specifically to unstructured addresses in wholesale payments.
Payments without properly structured data will not pass validation and must be resubmitted with correct formatting.
