I don't think they like switched fuses - I assume you can then turn off

No the switch fuse would be mine, so it goes after the meter Which is
the suppliers). If I wanted to tamper with the meter I'd consider
working live but why risk that when you can simply pull the cutout
(which is the DNO's)? If you are worried about the wire seals, eBay
is your friend.
