How Open Banking Works, and How CleanBooks AI Secures Your Data

September 22, 2026 3 min read

Quick answer: Open banking is a UK-regulated system that lets you grant read-only access to your transaction data to authorised third parties, without ever sharing your online banking password. CleanBooks AI uses this to import transactions automatically; it can see and categorise your transaction history, but it cannot move money or take any action on your account.

Connecting your bank account to any third-party software understandably gives people pause. Open banking exists specifically to make that connection safer than the alternatives, and it’s worth understanding exactly what it does and doesn’t allow.

What open banking actually is

Open banking is a regulated UK framework requiring banks to allow customers to securely share their financial data with authorised third-party providers, through a standardised, secure connection rather than by handing over login credentials directly. It’s regulated by the Financial Conduct Authority, and any provider using it must be authorised to do so.

What access it grants, and what it doesn’t

  • Read access to transaction data, so your software can see and categorise what’s already happened in your account.
  • No access to your online banking password or login details; you authenticate directly with your bank, not with the third-party software.
  • No ability to move money, make payments, or take any action on your account; it’s strictly one-way, data out, nothing in.
  • Access that you control and can revoke at any time, directly through your bank or through the third-party provider.

How this connects to your MTD reporting

For CleanBooks AI specifically, this connection is what lets Keeva categorise transactions automatically without you manually entering each one, which is also what keeps your quarterly updates accurate and current with minimal ongoing effort.

Frequently asked questions

Can CleanBooks AI move money from my account?
No, open banking connections used for bookkeeping are read-only; they allow transaction data to be imported, not payments to be made or funds to be moved.
Who regulates open banking in the UK?
It’s regulated under the Financial Conduct Authority’s open banking framework, with third-party providers required to be authorised to access account data this way.
What happens if I disconnect my bank feed?
Your software stops receiving new transaction data going forward; historical data already imported typically remains in your records unless you separately request its deletion.
Is open banking safer than giving software my banking password directly?
Yes, significantly; open banking specifically exists to remove the need to ever share your actual banking credentials with third-party software, which was a real security weakness in older bank-feed methods.
