That would be the sneaky sort of thing the regulator would allow through. If you choose to accept an offer of a Smart Meter from your supplier it's optional, if it's part of the routine, statutory, replacement it's not.
Is that actually the case though? And how many suppliers actually do routine meter replacement? Note supplier not DNO, the meter is not the DNO's responsibilty theirs stops at the cut out.
