Open banking lets you securely share your bank data with regulated apps and services that you choose, to power budgeting tools, faster payments and smarter affordability checks. Here is how it works, how consent protects you, and how it is kept secure.
For most of banking history, your financial data lived locked inside your bank, and only your bank could use it. Open banking changed that — not by taking control away from you, but by handing it to you. It lets you decide that a budgeting app, a lender or another service can securely see your account information, on your terms.
The result is a wave of tools that can read your finances to help you, while you stay firmly in charge of who sees what.

Open banking is a system that lets you securely share your banking data, with your explicit permission, with regulated companies other than your own bank.
The principle behind it is simple but significant: your financial data is yours, and you should be able to let trusted services use it on your behalf. Instead of your information being trapped in one place, you can choose to connect it to apps that turn it into something useful — a clearer budget, a quicker payment, a fairer lending decision.
Crucially, you do this without handing over your banking password. The sharing happens through secure, behind-the-scenes connections that you authorise through your own bank.
Open banking runs on APIs — secure digital connections that let one system request specific information from another in a controlled way. If you want the full picture of how those work, our plain-English guide to APIs explains the concept.
A typical open banking connection goes like this:
The golden rule: a genuine open banking service never asks you to type your banking password into it. You always approve access through your own bank.
This design means the third party gets only the specific access you granted, and only because you actively allowed it.
What makes open banking trustworthy is consent. Nothing is shared unless you say so, and you remain in control throughout.
This is a meaningful upgrade on older, riskier workarounds where people shared their actual login details with third parties. With open banking, you grant permission, not your password — and you can revoke that permission whenever you like.
Open banking powers a growing range of genuinely useful tools:

Security is built into open banking at several levels, which is why it can be trusted with sensitive data:
That said, the usual caution applies. Stick to apps from reputable, FCA-authorised providers, read what you are consenting to, and review your active connections from time to time. Scammers may try to imitate legitimate services, so the same care you would apply to any unexpected message asking for access is worth bringing here too.
Open banking lets you securely share your bank data, with your explicit and revocable permission, with regulated providers you choose — powering budgeting tools, account aggregation, faster payments and fairer affordability checks. It works through secure APIs, never by handing over your password, and only FCA-authorised firms can take part.
The core idea is helping: your data, your choice. Used with sensible caution, open banking turns your financial information from something locked away into a tool that can work for you.
