OWG is quite right about brand protection.

You should also consider the benefits of localised search engines, such as Google.co.uk, ask.co.uk, etc. It can pay dividends to have strong rankings on those, and a national domain name is the safest way to do that. Plus it allows you to benefit from UK listings on UK search, but host it in the much cheaper US hosting market. :)
