Can you see what the green cable is connected to. Sounds like it
probably runs to an earthing rod.

I've had a bit of a dig about and it just goes deep into the earth.
Will it be ok exposed them if thats what it is? Won't the elements
damage it?

It's fine exposed it's standard practice. As long as it meets the
relevant regulations - there various specifications for the size of the
cable depending on whether it is insulated (to protect against
corrosion, or run exposed or in conduit).

I can't remember it off hand, nor to I have my copy of the On-site Guide
to check the details.

You should however be able to find the end of the earth rod it connects
to so you could check it. If that connections was to break or become
poor then you would have a potentially dangerous installation.
