It's not just a cash machine though, its a free withdrawal cash machine.
This all needs to be put into a charter for a UK Banking licence along with not being able to refuse a basic account for a UK resident unless otherwise approved by the FCA or similar.
The solution is fairly easy. All the Banks need to do is join forces (like they do with EoC and CLS) and have a single owned company that deals with this for all of them. It shouldn't be difficult or indeed any more expensive than current, might even come out cheaper.
//98%+ are already within 3 miles of a cash machine.//
Yes, but going forward?
//It's strange that they can always "do something" about problems which either don't exist or are minimal in effect//
Whilst I have sympathy with the comment surely it is good they are pre-empting a future issue? And that is how it should be. We would soon all knock them further down the line if they did nothing.
