Lighting circuit without earth...can I move ceiling roses without rewiring the whole circuit?

I'm sure you understood what I meant..

TBH, I wasn't sure what you meant!

TBH, I wasn't sure what you meant!

I made (as it turned out) a wrong assumption about the age of the entire installation, which if it was done in the early 1960 would be ripe for a rewire, rather than an ECR.

Ah, got you.

I'm thinking about likely EICR results, which do matter to me.

411.3.1.1 Protective earthing
Exposed-conductive-parts shall be connected to a protective conductor under the specific conditions for each type
of system earthing as specified in Regulations 411.4 to 411.6.
Simultaneously accessible exposed-conductive-parts shall be connected to the same earthing system individually, in
groups or collectively.
Conductors for protective earthing shall comply with Chapter 54.
A circuit protective conductor shall be run to and terminated at each point in wiring and at each accessory except a
lampholder having no exposed-conductive-parts and suspended from such a point.

As @flameport said this has been since 1966, now as far as an EICR goes, there should be just 3 codes of interest i.e. fail, Code FI and Code C1 not really interested with, it is Code C2 = Potentially Dangerous, without a label likely would get C2 the label may mean it passes, the electrical safety council best practice guide states

Absence of a circuit protective conductor for a lighting circuit supplying items of Class I equipment, or connected to switches having metallic face plates

as Code 2 which seems to imply if Class II equipment it is not Code 2.

It states under "Non-compliances with the current edition of BS 7671 that do not give rise to danger and do not require reporting" "Protective conductor of a lighting circuit not (or incorrectly) terminated at the final circuit connection point to a Class II (or insulated) item of equipment, such as at a switch mounting box or luminaire." so it does seem you may get away with it.

regs are not statutory

However read this forum and you will see many don't follow what the Electrical Safety Council says, so if you want a pass with an EICR then

There are two ways to do electrical work - properly or not at all.

If you need an EICR then we must assume it will be rented, and really you have no option, follow what @flameport has said, either don't touch it, or do it proper.

Once you write out a label or a minor works certificate you are telling everyone you know it is not right, but you are doing it anyway.

Then it is inaccurate.
A "non-compliance" is a "non-conformity" (with the regulations) that may give rise to danger.

and do not require reporting" "Protective conductor of a lighting circuit not (or incorrectly) terminated at the final circuit connection point to a Class II (or insulated) item of equipment, such as at a switch mounting box or luminaire." so it does seem you may get away with it.

You mean it is allowed - not "may get away with it".

However read this forum and you will see many don't follow what the Electrical Safety Council says, so if you want a pass with an EICR then

The Electrical Safety Council is a part of NICEIC and just something that someone there has written with no authority.

If you need an EICR then we must assume it will be rented,

Why? Apart from the fact that Gareth has said it is not at the moment, you frequently say in posts that installations have inspections every ten years even though most people never bother.

and really you have no option, follow what Flameport has said, either don't touch it, or do it proper.

It is impossible to earth plastic items so what difference is an unconnected CPC(earth wire) going to make?

Once you write out a label or a minor works certificate you are telling everyone you know it is not right, but you are doing it anyway.
