Can't speak for the UK, but at least in Austria a company bank account is no different from a personal bank account, at least as far as technology is concerned.

That said, I know at least a couple of (admittedly rather large/corporate) companies that explicitly opted out of instant transfers for some reason.

I can't comment on technologies, but the user interface for a business user might be different from that for a home user.

As for fees, they tend to lure individuals with free this, free that, while taking kidneys and other organs from businesses.
