main switch question

There is no requirement for RCD protection of socket circuits, unless the installation is considered a special location.
Just wondering whether the meter is single or 3 phase?

Good luck with that.

Thanks for that, as you can see from what you have quoted, there is no requirement for the circuit to be provided with RCD protection.

Socket-outlets are required to be provided with RCD protection, not the circuits supplying them, except in some instances where the installation is considered to be a special location, such as Horticultural or Agricultural.
In fact providing RCD protection for such circuits could be a non-compliance in some circumstances.

if the cable is not more than 50mm in wall or has mechanical protection then it needs an rcd

Exceptions still exist with a risk assessment

Who mentioned a dwelling ?

Still no requirement for socket circuits to be provided with RCD protection.
Yes there are circumstances where it may be advisable, or the simplest solution to provide RCD protection for such a circuit.
However it still remains that there is no requirement in BS7671 for such circuits to be provided with RCD protection, except in some circumstances where the installation is considered to be a special location.
Doesn't matter whether there is a dwelling involved or not.

Yes socket-outlets, not the circuits supplying them.

The difference is the regulations say socket outlet and not circuit. For example you could have the circuit installed surface so doesn't require RCD protection but you would install a RCD socket outlet to comply.
