In Britain the accent changes hugely if you travel even twenty miles (sometimes less). I don't know much about it, but when I was researching it for something else the British Library website has a map of britain where you can (if you have windows) listen to various dialects.
If you google British Library Regional Dialects, then it should come up. Yep, it does.
I hope that's helpful/ someone else on here might give you more detailed information.



It's so overused in EVERYTHING. I'm English and bad at explaining things, so I'll give a brief summary of accents I'm good at doing within my own country. I'll leave the Scottish, Welsh, Irish and more specific English dialects to better people.
I know many comedians with accents but I can' remember their names. I'll edit back later.
