Frequently Asked Questions

What types of financial data does Bud provide to lenders and fintechs?

Bud aggregates and enriches transaction data from UK bank accounts via Open Banking, providing normalized transactions, income verification, and affordability assessments. It can also be used for ongoing account monitoring and personal finance management.

Does Bud connect to all UK banks?

Bud uses Open Banking APIs to reach most UK banks and building societies. It also supports accounts that may not be accessible via direct Open Banking connections through additional authentication methods, though coverage may vary.

Is Bud PSD2-compliant?

Bud supports regulated Open Banking and PSD2 requirements, but how it is delivered depends on the license you operate under. You will need to ensure your own AISP/PISP permissions cover the use case, or work with Bud's regulatory status if applicable.

Is the API free with no hidden charges?

The core API can be free for sandbox and limited testing. For production usage, you may need a paid plan or may be required to pay for additional support, SLAs, and access to full transaction data — review the current pricing details.

How is Bud different from traditional credit bureaus like Experian?

Bud focuses specifically on transactional Open Banking data, not traditional credit bureau files. It provides raw financial behavior insights and affordability calculations based on bank feeds, rather than credit scores.

Can Bud help with mortgage affordability or consumer lending under FCA rules?

Yes, Bud provides income and expenditure insights that support responsible lending decisions. Its affordability and income verification features are designed to help lenders comply with FCA affordability requirements.
