He spoke to the supplier, who said that he can get any registered
electrician to move it.

A registered electrician has done so, but of course broken all the seals

I understood that only the supplier can move it - is that still the
case?

It has been covered a few times here and appears not to be a problem. The
'official' way appears to be to write a notification of works to the supplier
telling them what is about to be done then write to them after the works to
tell them that work has been completed and inviting them to re-seal the
meter connections at their convenience. It's really an arse covering
exercise so make the second letter recorded delivery.
