If it is even possible can someone tell me the best web designing companies in UK (top 10 or something like that). I need it to look at their design and everything. Thanks in advance

Define "best"? Everyone will have a different opinion on that one (I'm #1 btw... j/k ).

 

Or there's "highest turnover", "highest profit", "most customers", "best reputation", "best SEO".... It's very hard to quantify.

Not necessarily the "best" but these guys seem to be high profile...
