If you set up a reverse proxy properly, the search engines will treat the content in www.website.co.uk/blog/ as normal content on that main site.

It's not trivial to set up, but it's designed for specifically this kind of scenario (e.g.  a subdirectory displaying content using a technology that can't be installed on the main-site server.) You'll also want to make certain things like cookie persistence, Analytics etc have been accounted for.

Hope that helps?
