Domestic Installer - a scheme that covers general electrical installation work in UK domestic properties only

Domestic Installer - a scheme that covers general electrical installation work in UK domestic properties only. But what if the dwelling has 3 phase due to size of house or for Solar PV or EV (Electric Vehicle or HP (Heat Pump)?

Eg

Single phase safe isolation 3 point test at 230v AC nominal

3 phase 10 point test but at some point phase 1 to phase two at potentially 400v AC

As always please be polite and respectful in this purely academic debate.

In some parts of the country the policy seems to be to install 3-phase for domestics by default now - to cater for future EVs, Heat Pumps etc.

Some network faults (lost Ns) can potentially put 400V or so across single phase supplies - so that's something that the equipment and procedures should handle anyway.

The CPS's say Domestic Installer is only 230v in dwelling like house/flat thus if 3PH gets fitted this will leave people having stern conversations.

where does it say that? (seems odd, since part P will certainly cover many 3-phase (even some 460V split phase) installations).
