How UK budgeting apps use Open Banking, how to check a provider is FCA-authorised or registered, what access you are granting, how to revoke it, and how to choose an app that suits you.
Budgeting apps can pull in transactions from all your accounts, categorise spending and show where your money goes. Most do this through Open Banking, which is regulated and designed to be secure, but you are still giving a company access to sensitive data. A few checks first are worthwhile.
How Open Banking works?
With Open Banking, you give an app permission to read your account data through your bank's secure system. You log in on your bank's own app or website, not in the budgeting app, and you never hand over your banking password. Providers offering this account information service must be authorised or registered by the Financial Conduct Authority (FCA).
Most budgeting apps only have read-only access. Some services also offer payment initiation, which lets them make payments with your approval; check what you are agreeing to.
Checks before you connect
- Check the FCA register. Search the app's company name on the Financial Services Register. Some apps use a regulated partner for the Open Banking connection; the app should say who.
- Never share your banking password or one-time codes with an app. A legitimate Open Banking app redirects you to your bank to approve access.
- Read what data is accessed: balances, transactions, account details. Check how long access lasts.
- Read the privacy policy. Does the company share or sell data, for example for marketing or credit offers? How long does it keep data after you leave?
- Check the business model. If the app is free, how does it make money? Commission on products it recommends can affect what it suggests.
- Download only from official app stores and check the developer name matches the company.
How do you revoke access?
- Remove the connection in the budgeting app's settings, and
- check your bank app. Many banks show a list of connected third-party providers you can remove.
- If you delete your account, ask the company to delete your data. Under UK GDPR you can request erasure in many cases.
Choosing an app
- Your bank's own tools: many UK banking apps now include spending categories, budgets and savings pots, with no extra data sharing.
- Aggregator apps: useful if you have accounts with several banks and credit cards.
- Zero-based budgeting apps: give every pound a job; good for people who want close control, often paid.
- Spreadsheets: free and private, with no bank connection needed; more manual.
Features worth having
- automatic categorisation you can correct;
- alerts for bills and low balances;
- a clear view of subscriptions and regular payments;
- export of your data, so you can leave without losing history.
Making a budget stick
- Start with three months of actual spending, not guesses.
- Separate essentials, regular bills and flexible spending.
- Set a few realistic limits rather than many.
- Check in weekly for ten minutes.
- Automate savings on payday.
Couples and shared finances
If you budget with a partner, decide which accounts each of you connects, and whether you want a joint view. Some apps support shared budgets; others work better with a joint account for shared bills and separate accounts for personal spending.
Scams to watch for
Fraudsters impersonate finance apps, banks and the FCA. Be wary of unsolicited messages asking you to "verify" an app connection or move money. Report suspected fraud to your bank immediately, and to Report Fraud.
Frequently asked questions
Is Open Banking safe?
It is regulated and you never share your bank login. As with any service, check the provider and only share what you need.
Will a budgeting app affect my credit score?
Reading your account data doesn't affect your credit score. Credit checks only happen if you apply for credit.
