Banks that delay in providing customer data are under scrutiny. The suspicion is that they are deliberately hindering companies they see as potential competitors.

Customers give their consent to the transfer of data necessary to use the FinTech company's services. Competition regulators have conduced dawn raids on banks suspected of intentionally holding up the transfer.

The raids were reportedly on Polish and Dutch banks, but they were coordinated by the European Commission. Those having difficulty getting data from UK banks can complain to the Commission or to the UK authorities, or they could threaten to do so, to try to speed up the process.

The European Commission can confirm that on 3 October 2017 its officials carried out unannounced inspections in a few Member States concerning online access to bank account information by competing service providers.
