The only option we have really is to sink more money into the site to try and fix what might have gone wrong.

Reread my post above..IMO the "might(s)" are fairly clear..and bear in mind that the algo(s) which assess sites at Google..assess UK and USA as "English language"..thus it is critical that a site which targets the UK makes it very clear ( not just via a dotcodotuk ) in it's content, images etc, precisely which English language market it is aimed at..

It should be possible ( without looking at the domain name or the address bar ) for any visitor ( and search engine algo(s) ) to be able to say ..this place is for Brits..or this pace is for Australians etc..

Spelling "colour" and "grey" correctly ;) is not enough ..the site should have a strong visual and vocal Brit accent..

Even more so if there is another site treating the same subject that has been established, longer in another English speaking market..especially if that market is the USA and they are the dotcom..

Google will accept both a dotcom and adotcodotuk, as worthy of ranking highly, but it must be able to distinguish between them so as to say ..two sites,one subject, two markets, and WMT is not the way to tell them..the site and it's "accent is ..:)

Bear this in mind for your other sites..before you take them live..and don't decide if they look "Brit enough" yourselves..get people outside your team to assess that ..and listen to them..don't influence or "correct" them...
