I think it looks quite good. The overall feel is quite regal and smart and everything seems to work. You're using the SEO WP plugin so you should be covered there if you put some time into your descriptions etc.
I don't like the logo, well, the UK bit tagged on to the end. It doesn't look very good with the thick typeface, which doesnt appear to be aligned.
There is a full stop on the testimonial page all on its own.
I'm not convinced by the orange. Maybe you were going for gold, but it doesnt come across like that. Personal preference rather than serious flaw though.
