Thanks for the feedback and discussion everyone. We’re always considering new providers to support and community input has definitely been one of the key drivers when prioritising new integrations, so I’d like to shed some light on how this works internally 
If an integration doesn’t exist it’s probably because one of the following:
- Doesn’t have a significant customer base (we measure this both from observing transfers to/from that sort code from our users and community feedback)
- Their PSD2 API isn’t Open Banking (although we made an exception with Amex due to huge demand)
- We made the integration but ran into technical difficulties that the provider hasn’t been able to resolve yet, so we may be forced to hold on launching all or some part of the integration. This doesn’t tend to be a problem, but if there’s an obvious candidate you don’t see on the list and the points above don’t apply, this is probably why.
Adding a new provider that has a good Open Banking API is actually relatively straight forward, so if you think we’re missing someone, do let us know!
