company name keywords in url not ranking

Can anyone help - I have two clients who both have important keywords
in their url i.e. their main keywords are actually their company name
also. When I use the company name as part of the Meta Title for the
home page, Google does not rank the page at all. The other search
engines seem happy having both the url and the Meta Title the same e.g.
www.durham-precision-engineering.co.uk with the Meta Title "Durham
Precision Engineering - Sub-contract..." Hope this makes sense and
someone can throw some light on why Google doesn't like it.

Go to the home page of the site and hit refresh while keeping your eye
on the blue bar where the title tag shows up. The text changes, I
think Google may be seeing a different title tag.

However, I dont think that, that would explain it all
