Putting UK in the search will really limit the results as it will be biased to pages with UK in them (WikiWirral doesn't have UK on most of the pages).
Google are trying to force people to log into google, there used to be three methods of biasing to uk without logging in but they have gradually removed them.
I got the link wrong above, it should have been https://news.google.com/news/local
to give it a more open search. Mine still comes up as Formby but sets the language and edition to US.
The other thing that might bias google AGAINST uk is if the home page on Chrome isn't set to a uk page, google uses your History
to guess what you want to see, eg if your home page is donaldtrump.com then it might assume you are an American.
Google reckon google.co.uk and google.com are the same these days but I've noticed a difference by using google.co.uk even though it usually redirects you to google.co.uk anyway.
