Your Facebook page has the UK identifier in its URL, Sherrardk. It's en-gb.facebook.com/ followed by your name, which is what I'd expect for a UK-based FB member's page. However you can still give out your address to others without the en-gb bit in it, as facebook.com/ (followed by your name) automatically redirects to the true address.

Unless your FB name is 'Home' (which I very much doubt!) you've not given anything away!

My post, above, refers to what I see (as someone who's not logged into FB) when looking at your page. What you see, once you've logged in, might be different.
