I just join today after doing a Google search for Thuja Green Giant.
What a wonderful site, so glad to have joined, just sad i didnt find it
sooner.

FYI - the "site" you refer to is someone's web interface to
pre-existing global discussion groups called "usenet", which have been
around for over three decades.

Could anyone help me out a little more on this. Is Green Giant grown in
the UK, are they available to even buy here? And if so, could someone
please link me to a recommended site to buy from.
I went to my local garden nursery this morning to find nothing and i
have searched online garden nurseries and again, to no joy

Over here in the states, we know this as "Western Red Cedar" (not to
be confused with the shorter "Eastern White Cedar"). You might try
searching your local nurseries for that. It's actually a cypress.

Note that article describes three cultivars.

The nursery the article cites is in Australia, and they have several
other cultivars:

When you want a hedge, do you really want a tree that could climb to
10 metres or more? Or one which generates lots of litter? Consider
also the sort of watering it may require (yea, you're un the UK -
where there's pretty much one season "rain").

I performed a simple google for:

"western red cedar" "united kingdom" nursery

Among the first page of results found these nurseries (though
originally linked via company directory sites):
