i like the design nice and clean and to the point, from a design point of view though it might be something to consider that your header of the page (the roof image and the accreditation links and images) are the same on each page, which is fine but people tend to be hooked by what they can see on their page without scrolling down, unless they are looking for something specific a bit like the first couple of paragraphs of a novel etc.
would it be worth seeing if you could scale some of it down and fitting slightly more information which is relative to the company the design is for on the intial screen size so that people are offered some information aswell as the company identity?

sorry if my comments are out of place, they are in no way meant to offend
