Thanks plumbob.
In the meantime, I've been talking to an aquaintance earlier today who, unbeknowns to me, used to be a plumber; he pointed out to me that the pipe between the company valve and my internal stopcock is actually my responsibility, so if I had a problem in it, it would be up to me get it sorted; so it makes perfect sense for me have legitimate access to it.
For ages I've been under the impression that my internal stopcock was the customer / company interface, but clearly not.
Their responsibility and ownership stops at your boundary. Any pipework or installation after that is yours to look after. The only exception is if a water meter is fitted. That and it's immediate fittings associated with it (but not the supply to it) remains their responsibility simply because you will have no access to it because of tamper-proof seals.
