Need to increase your granularity a bit. I live in Wexford Town, Ireland, and the other day I was chatting to a person that told me their old schoolmates from Castlebridge are making fun of their accent changing since moving from their hometown.

Castlebridge is 10 minutes away by car. Madness!

Yeah, totally agree. Here's a useful link for non-Brits, that goes into a bit more detail:

Also, we have yet to define precisely define what is meant by 'British'. This probably needs a "20 falsehoods people believe about..."-type article.
