Open banking

Definition

Open banking lets a company grant a lender secure, read-only access to its bank-account data through a regulated connection. Instead of static statements, the lender sees live transaction data, giving a truer picture of the cash a business actually generates.

Why it matters

It speeds up and sharpens affordability assessment, and helps younger companies prove cash flow without years of accounts. See affordability for young companies and how lenders assess affordability.

In practice

Say a UK limited company is applying for finance and its accounts are thin or slightly out of date. Instead of relying solely on filed statements, the director connects their business bank account through open banking so the lender can view actual transaction history directly from the bank. There is nothing to compile, scan or forward manually — the data comes straight from an authorised, regulated channel, and only in read-only form.

For the director, the practical effect is a faster, less paperwork-heavy application: no chasing PDF statements from a business banking portal, no redacting sensitive lines by hand. For the lender, it means underwriting against what the company's account genuinely shows week to week and month to month, rather than a snapshot that may already be dated by the time it is reviewed.

Common pitfalls

A common misstep is connecting the wrong account, or only a secondary one, so the lender sees a partial picture of trading activity rather than the account the business actually operates through day to day. Where a company holds several accounts across different purposes, it is worth being deliberate about which one is linked.

Another pitfall is treating the connection as a one-off box to tick rather than something to keep live if a lender's process needs ongoing visibility during the relationship — for example if affordability is reassessed later on. Directors sometimes assume consent, once given, persists indefinitely; in practice it is worth checking how long access remains valid and renewing it if the lender's process requires continued visibility.
