XF 1.2 English (UK) Language

I've just got my forums up and running the way they should be after a lot of hard work but I've just noticed that there's only one language pre-installed which as you know is English (US).
My site is purely UK based (Kayak Fishing UK) and we need to be using our own language and not a *******ized version of it so is our language available as an import at all? I've searched as much as I possibly can without success?

WOW amazing stuff and thanks for the lightening quick reply Brogan. After poking around I've discovered my Firefox had defaulted to US English maybe via last upgrade so it was that causing the issue and not the FX board but I will edit it anyway.

thanks for your help (again)

edit: hmm, just noticed the 51 pages! ooer!
