Can I re-site a meter (inside property)?

[WaterTight]

Hi,
Am I allowed to move a water meter? It's in a kitchen cupboard and she wants a Surestop fitted and in order to do so I'd need to move the meter somewhere else in the cupboard.
There is an original old stopcock inconveniently placed she can't get at, then the meter. I'm thinking as long as I leave this original stopcock in situ I can also fit the Surestop after the meter if it makes it easier? As long as it's still before any tee off's?
Thanks
Ryan

Correct I would depending on the stop tap change this as well (stop tap)
