I have seen many older CUs provided with an external RCD. Perhsps there is one. We cannot guess.
What has 6amp to do with anything? It doesn’t matter if the new circuit only provides power for one tiny lamp at the top of a Christmas tree, if the wiring is concealed, or has a socket then an RCD will be required.

You are talking regs now. The reality is that the single cable will supply double insulated data equipment in a cupboard. The socket will be plastic. The equipment will be on 24/7. It is not a power ring with high current metal kettles & heaters open to people touching the metal surfaces and the likes. That is where people's safety is then paramount. It will be fine for a few years until update. Risk of electrocution on this circuit is very, very low. A new 32A ring would need the RCD for sure.

data equipment in a cupboard.

the sort of thing that would often run off a 13A spur, you mean.

may need another circuit.

Why?

Yes of course I’m talking Regs. We don’t choose which ones we don’t like. Or is that the way you go about things?
It doesn’t matter what’s on the end.
A 6A circuit will kill you just as much as a 32A one.

. It will be fine for a few years until update

Even temporary installations must comply with BS7671.

Probably, but with a 6A fuse, or as it is a single purpose circuit an unfused switch and just a 6A mcb. Could put in one of those RCD sockets. But overkill for light, double insulated, data equipment in a cupboard.

Why?

It may, I am assuming it will.

We choose to use common sense as well. I explained what the circuit will be and what it will be powering. A very low risk. The installation has been there for over 30 years without any incident or failure.

A new circuit on an exiting CU and installation needs RCD?

Yes, and it is notifiable so anyone doing it legally will fit an RCD - end of.

The new circuit will only be 6A supplying double insulated data equipement.

Still possible to drill through the cable; still 240V.

Yes, and it is notifiable

Notifiable? Anyone can fit electrical equipment, there is not the likes of GasSafe for electricity.

 

[EFLImpudence]

New circuits are notifiable to the Local Authority before commencement of the work if a registered electrician is not doing it.

The Local Authority might deem you not competent enough.

Competence is the result and safety when performing the job. Qualifications (a bit of paper) does not come into it. Similar with gas.

 

[EFLImpudence]

Where did I mention qualifications?

My link is the actual law; yours is written by someone unnecessarily.

 

[Taylortwocities]

I can see why you have chosen that forum name.

 

[EFLImpudence]

Actually, after a quick look, your link, although far longer than the actual law, seems quite reasonable.

It states:
"2.7 Regulation 12(6A) sets out electrical installation work that is notifiable."

You may notice these two numbers, 12 and 6A at the beginning of the page in my link.
