Hello and thanks for your message. This could be the case. I have read elsewhere of websites who moved servers to other countries and it did not affect their rankings for where they wished to place. So, I am not certain that this is 100% the case, but could be a part of it. Do I need links from Co.UK sites? Might that help? Or, should I have a dedicated En-GB (English Great Britain) dedicated page? That seems redundant, but mentioned a bit here: http://support.google.com/webmasters/bin/answer.py?hl=en&answer=189077
Thanks for your help guys : )
