Metering a small supply
Avoid the cheap little ones though. As the meter will be used to calculate how much is owed it needs to be an MID approved meter.- freddo

Meter tails no rcd in stud wall
The tails to my flushed in consumer unit are in a stud wall for a short section, so to avoid the need for an RCD I put 32mm galv conduit into the stud wall for the tails, bushed into the side of the consumer unit.- freddo
