Going back to Freddie.. i think Wilson is from Northern Ireland . His accent is a bit meandering i must admit

Can't always trust Wikipedia, but this rings true with other information I've seen (he talks fondly about growing up in Glasgow and buying magic from the magic shop there):
R Paul Wilson (born in Akrotiri, Cyprus and raised in Singapore and Scotland) is a close-up magician, and television presenter. He lives and works between London, Los Angeles, and his home in Scotland. He lives in Glasgow with his wife and children.

So his accent is mostly Scottish but has other influences in there.
