Open finance regulation: FCA sets 2027 framework deadline as SME credit and mortgage access take priority

The UK's Financial Conduct Authority has published a formal open finance roadmap, targeting a complete regulatory framework by end-2027 and committing to practical use-case development in 2026, with SME lending and mortgage access named as the first two priority areas.

The announcement marks the regulator's most concrete step yet toward extending the data-sharing model of open banking, which now counts approximately 17 million users, or nearly one in three UK adults, across a far wider range of financial products including investments, savings, pensions, and insurance.

What does the FCA's open finance roadmap actually commit to?

The FCA's vision stops short of mandating open finance immediately. Instead, the regulator will work with HM Treasury on framework options through 2027, while simultaneously using its Smart Data Accelerator sandbox and the newly established PRISM (Prioritisation and Real-world Insights Selection Matrix) Taskforce to identify and test priority use cases from this year.

Firms already able to access relevant data and appropriate customer permissions will be supported to launch open finance products ahead of the formal framework. This dual-track approach, permitting early movers while building long-term rules, mirrors the phased rollout that characterised open banking's own evolution under the Competition and Markets Authority after 2017.

David Geale, executive director for payments and digital finance at the FCA, framed the initiative in terms of consumer outcomes: giving people and businesses "more control over their own financial data" to access credit, secure better deals, and receive more customised support.

Why are SME lending and mortgages the opening priorities?

The FCA's selection of SME credit access and mortgage management as the first use cases reflects persistent structural gaps in both markets. UK small businesses have historically faced slower loan approval timelines and higher rejection rates compared to larger corporates, in part because lenders lack a holistic view of a company's financial health across multiple providers.

Open finance could allow SMEs to consent to the sharing of accounting data, tax records, and multi-bank cash flow information in a single credentialled handshake, compressing application and underwriting timelines significantly. In the mortgage market, a similar mechanism could allow advisers and lenders to assess affordability across savings, investments, and income streams without requiring manual document submission.

"Just as open banking has sparked the growth of many UK fintechs, so open finance can power a new wave of innovation. By unlocking high-quality data in a way that secures consumer trust, open finance can be a foundation for widespread adoption of agentic AI."

Adam Jackson, Chief Strategy Officer, Innovate Finance

How large is the economic opportunity?

Research by Open Banking Limited and EY puts the combined economic impact of open banking and open finance at up to £7.4 billion per year within five years, a figure that dwarfs the estimated direct value currently generated by open banking alone. That projection assumes successful execution of high-value use cases including SME lending, investment aggregation, and insurance underwriting, all of which require the broader data permissions that only open finance can unlock.

What is the connection to agentic AI?

Innovate Finance's Jackson explicitly linked open finance to "widespread adoption of agentic AI", a framing that positions the data infrastructure not merely as a fintech utility but as a precondition for the next generation of autonomous financial planning tools. Agentic AI systems that can act on behalf of users, rebalancing portfolios, switching providers, optimising savings rates, require the kind of permissioned, real-time, multi-product data access that open finance is designed to provide. The FCA's roadmap does not address AI governance directly, but the regulatory architecture it is building will determine the data substrate on which those systems operate.

What should financial institutions do now?

Firms with existing data access agreements and customer consent frameworks are explicitly encouraged by the FCA to begin product development now, without waiting for the 2027 framework. For institutions that have invested in open banking infrastructure, the near-term opportunity is to audit existing data permissions and assess which open finance products could be layered on top of current capabilities.

The FCA's engagement programme through 2026, covering industry, consumer groups, and fellow regulators, will also be a critical venue for shaping which use cases receive regulatory priority. Firms with a commercial interest in specific verticals, such as SME credit or pension aggregation, will want representation in those consultations.

Why this matters to FinanceX readers

Open finance is not a distant regulatory aspiration, the FCA's 2026 engagement calendar and explicit support for early movers means commercial activity will begin well before any framework is finalised. For investors, the announcement strengthens the long-term thesis for UK-based wealthtech, lendtech, and data infrastructure players. For financial institutions, the SME credit and mortgage priorities signal where the first competitive disruption will occur. The £7.4 billion annual economic opportunity figure, while headline-level, reflects a genuine structural shift in how credit is assessed, products are priced, and financial advice is delivered in the UK.
