As one of the guys who helped to implement Faster Payments in the UK. I do find the Currency Cloud solution a little hit & miss. So, first up there is only one mass instant payment scheme in the UK and that is "Faster Payments", the maximum amounts you can send is limited to £1m but banks can set their own lower limits. Usually, the limit is lower for personal customers and higher for business customers. For amounts over this a separate system called "CHAPS" is used "Clearing House Automated Payments System" According to Currency cloud website, Faster Payments for inbound receipts is live and is the primary method for crediting GBP wallets. Given these are neo banks as opposed to what we call in the UK 'Clearing Banks' there are likely a number of hops involved. There is also a question about whether Bunq make a hold and fund wallets in a delayed manner to manage margin settlement. That is the balance between what is sent / received each day. Though, again according to Currency Cloud margin for gbp can be sent via "Faster Payments" too. I would be interested to hear more about peoples experience......
