Just a conclusion to this. I was uable to find any way to get find and select Google UK as a serach provider using the drop down menu provided in IE8. A long search revealed that this is a well known problem but finally provided this link however:
http://www.microsoft.com/windows/ie/.../runonce2.aspx
This is a Microsoft page which allows you to find and add a new search provider. I did this and once added was able to set GoogleUK as my default hence ridding myself of the dreaded Bing.
A happy end.
Thanks for the help guys.
