What is ISO 20022?

The payments landscape is transforming around the world. ISO 20022 is the newly established global standard for payments messaging for the UK, European and other international cross-border payments.

This is a significant change and will eventually mean that there will be a common standard for payments messaging in every country. The new standard means more data of a better quality can be included in payments messages. The benefits of adopting a global standard for payments messaging will result in future innovation and development to deliver a better payment experience for customers.

Identifying property related CHAPS payments

We now require you to select a purpose for any CHAPS payment that relates to property - for example, sending rent, or paying a deposit. We’ll provide further guidance across our payment channels. See below for more information about why we need these.

Key benefits of ISO 20022

  • Flexibility – ISO 20022 is a global standard that allows for faster troubleshooting and maintenance and can be adapted to be responsive to changes in the economy and new technologies.
  • Harmonisation – A worldwide, standard language across payment systems. 
  • Enriched data – More data will be able to be held in the new payment message format, which contains richer information, providing better business intelligence and reconciliation opportunities.
  • Competition – Increased flexibility and modernisation will stimulate innovation in the financial sector, allowing for the development of new products and services.
  • Better processing –  There will be fewer issues with incomplete or unstructured data, resulting in fewer failed payments and improved customer service.

Some of your questions answered

What does this mean for my business?

You will need to make sure your payment systems can send and receive payments in the UK and internationally using the new ISO 20022 format. This could mean that you need to make changes to your systems. With this in mind it is advisable to prepare early to avoid any disruption to your business. 

What changes will I need to make?

You may want to start investigating changes that may need to be made to your initiation or collection of CHAPS, Euro and SWIFT payments which will all be affected as the new standard is adopted. Bear in mind that if you use third-party suppliers to support your payment operations and systems, they may also be affected.

As the migration to ISO 20022 progresses and details of any changes that impact our payments service to you become clear, more information will be made available here on our website or will be shared with you through your account manager.

Who will be impacted?

Any business, commercial and corporate customers that make and receive UK, Euro and cross border payments will be impacted along with financial institutions e.g. other banks.

What is the timeline for migration to ISO 20022?

SWIFT and Euro payment systems transitioned first to align with the new payments format, in March 2023 with full migration of payment messages across global payment infrastructures expected to be late 2025. Changes to CHAPS payments were made in June 2023 replacing previous payment messages with the new enhanced ISO format.

The timelines for the migration are determined by the different payment schemes and regulators and so are subject to change and adjustment. 

What is meant by enhanced data?

The ISO20022 message format now allows additional information to be carried in a payment message – this is known as enhanced, rich or structured data. Purpose of Payment Codes are one of the new enhanced data elements which can now be included.

The inclusion of rich and structured data will make payments safer, more secure and more certain to reach the beneficiary without breaks in the journey. 

What is a Purpose of Payment Code?

These are new codes which can be included in payment messages which use the ISO 20022 format. They tell participants in the payment chain the reason that payment is being made.

As the ISO20022 format migrates globally, they will become internationally recognised and accepted.

Going forward, purpose of payment codes for property related CHAPS payments are being strongly encouraged by the Bank of England. These will become mandatory from 1 May 2025.
