News Type: API Calls

Twin milestones underline the UK’s position as one of the world’s leading Open Banking ecosystems.

London, UK – The UK’s Open Banking ecosystem has reached two landmark milestones, with more than one billion Open Banking payments and 100 billion API calls now recorded across the CMA9 banks since the launch of Open Banking more than eight years ago.

A defining moment in the evolution of Open Banking in the UK, these milestones demonstrate how the initiative has become an integral part of the UK’s financial infrastructure, enabling millions of consumers and businesses to access innovative financial services, make account-to-account payments, and manage their finances more effectively.

The latest figures demonstrate that adoption continues to strengthen. During June, the ecosystem recorded 2.81 billion API calls, an increase of 4.4% month on month and the highest monthly volume recorded to date, reflecting sustained demand for Open Banking-powered services.

Open Banking payments remained resilient at 40.16 million during June. While Single Domestic Payments declined by 1.2%, continued growth of Variable Recurring Payments (VRPs) which increased by 6.7% month on month, helped maintain overall payment volumes and highlighted a growing area of innovation.

The latest performance data also demonstrated continued operational strength across the ecosystem. Average response times, the time it takes for a provider to respond to a payment request, improved to 349ms, 50ms faster than the previous reporting period, reflecting ongoing optimisation and performance improvements by ecosystem participants.

Henk Van Hulle, CEO of Open Banking Limited, said:

“These milestones reinforce the UK’s position as a global leader in Open Banking and demonstrate an ecosystem that continues to scale in both volume and capability. As adoption increases and new use cases emerge, Open Banking will play an increasingly vital role in supporting competition, innovation and growth across the UK’s financial services landscape.

“As we look ahead, our focus remains on building on these achievements. By continuing to strengthen resilience, performance and innovation, we can unlock even greater value for consumers, businesses and the wider economy, while supporting the next phase of the UK’s Open Banking and Open Finance journey.”

In this press release you’ll read:

Record-Breaking Adoption: Open banking in the UK hit 15.16 million users* in July – nearly one in three adults – marking its fastest growth yet.

Momentum backed by legislation: The Data Use and Access Act is paving the way for the next phase of open banking, open finance, and smart data innovation.

Open Banking Limited (OBL) today publishes new adoption data showing record growth in July, as the UK cements its position as a global leader in digital finance.  

July was a landmark month for open banking, with more than 15.16 million people and businesses now using services powered by the technology – equivalent to nearly one in three1 UK adults.  

The latest figures also show that in July, open banking services were used a record 2.04 billion times, up 3.5% from June. From paying taxes to ordering dinner, millions of UK consumers and businesses are embracing open banking to manage their money with greater control, speed and confidence. 

Open banking adoption has risen steadily year on year – with total users growing by 34% in the last year. This reflects the growing consumer demand for secure, convenient, and transparent financial solutions, and continues a multi-year trend that has seen open banking move from a niche innovation to a core part of modern financial services.  

Payments remain the biggest driver of adoption, with July’s data revealing that the total value of payments has reached 29.89 million – an 8.7% growth (from 27.5 million to 29.9 million). This rapid growth demonstrates the UK’s global lead in data-enabled technology supported by strong infrastructure and rising consumer demand.   

Variable Recurring Payments for Sweeping (VRPs) are emerging as a key open banking enabled innovation, giving consumers and businesses greater control and flexibility over regular payments. In July alone, VRPs accounted for over 14% of all open banking transactions – a sharp 8.6% increase, to 4.26 million.

Single Immediate Payments are also driving growth. From HMRC tax payments (£4.7 billion in January) to retail giants like Just Eat and Tesco, and travel brands such as Ryanair, growing consumer and business trust is driving momentum and uptake across different sectors. 

The latest data from OBL comes in the wake of landmark legislation – the Data Use and Access Act – which paves the way for the next phase of open banking, open finance and smart data adoption in the UK. 

Looking ahead, the next phase of open banking will be shaped by the UK’s long-term regulatory plans. These are essential to unlocking further innovation, expanding adoption, and ensuring that the benefits of smarter financial services reach even more people and businesses. 

This data shows how open banking is now part of everyday life for millions of people and businesses across the UK – from paying taxes to shopping online. It’s fast, secure, and built on trust. 

To maintain momentum and unlock its full potential, we look forward to working closely with government, regulators and the wider ecosystem, ensuring open banking delivers even greater value, innovation and impact for everyone.”
