England-to-Wales Phone Call in the Early 90s...

[pleasure_past]

As I said in the title, the fic is set in the early 90s. I need a character in England to call a character in Wales. Is this going to be considered long-distance/is it going to cost more than a call to someone in England would? If it is going to be more expensive, are both parties going to be charged extra, or just one of them?

Thanks in advance for any help!

(Also, I don't really have any idea how to tag this, so for now I won't? None of the tags really seem to fit.)
