Looks fine in firefox.
One thing I will point out, that is a general comment.
I am an average person of the 21st century. I can not tell you where the yellow pages is located in my flat. I do not think I need it, I have a PC and I have google.
Now not comming from darn south, I have no idea where the home counties are (though I just checked on wiki) and my bet is google does not either.
Still confused? Well I use google but google is fairly dumb. It needs the website to contain the sort of things I would be likely to search for. It is not magic, it reads your site and then remembers it, then if I say to it window cleaner in surrey it has a little look through its memory and voila. A page of links relavent.
I might be wrong, but I do not think yours would be one of them (unless you specifically paid for it) as I can see no mention of the word Surrey on your site.
So, you should make a page called "Areas" linked to off each page where you list the areas you cover. What you are basically doing is trying to teach google that your page is relavent to window cleaner in surrey.
Yes I know I might be teaching my grandma to suck eggs, but sometimes we can get that mixed up the fine detail we miss the real thing we are trying to do (advertise).
Great site on my firefox though.
