Open finance could let mortgage applicants reuse verified financial information instead of repeatedly collecting statements and evidence—but the UK does not yet have a final mortgage data-sharing scheme. A new Financial Conduct Authority report explains what would have to work before the idea becomes useful in practice.
What does open finance mean for a mortgage?
Open finance extends the data-sharing idea behind open banking to a wider range of financial products. With meaningful consent, a customer could allow a lender or broker to access relevant, current information held by other providers. That might include evidence used to assess affordability, mortgage readiness or later remortgaging.
The FCA chose mortgages as a test case because applications draw on information held across several organisations and over long periods. Its mortgages policy-sprint report, published on 3 September 2026, reflects work with around 80 stakeholders and experts.
What could become easier?
Participants thought reusable evidence could help at several stages: preparing to apply, completing an application, managing a mortgage, remortgaging and making later-life decisions. Better data could be particularly useful for people whose income or circumstances do not fit neatly into conventional assessment models.
The benefit is not simply speed. A more complete and current record could reduce avoidable requests and help consumers understand what information affects an outcome. It could also make it easier to challenge a decision if the underlying evidence is wrong.
What safeguards would be needed?
The report highlights four recurring conditions: interoperable systems, meaningful consumer control, clear accountability and workable redress. Data would need to be accurate, current and accepted as trusted evidence. Consumers would also need to know who can see it, for what purpose, for how long and how permission can be withdrawn.
A slick interface cannot answer responsibility questions on its own. If data is incomplete, an automated result is unfair or several firms participate in one journey, consumers need a clear route to correction and complaint.
Is open finance mortgage policy final?
No. The FCA explicitly says the sprint does not establish a final ecosystem design or confirmed policy. Its findings will feed into a future discussion paper about key enablers. Commercial incentives and broad participation remain unresolved: a data-sharing network is less useful if important providers do not take part.
When could consumers see changes?
The FCA’s wider open-finance roadmap places evidence gathering and use-case testing in 2026, framework design in 2027, and scaling work across 2028 to 2030. That is a direction of travel, not a promised launch date.
For now, applicants still need to follow each lender’s evidence requirements. The practical takeaway is that mortgage data-sharing is moving from broad ambition toward testable design questions, while consent, accuracy and redress remain central.
