2 Switches 2 Lights need making independent

[Hounds]

Can anyone please help me.
I currently have 2 lights both controlled by 2 switches which come on / off when either switch is pressed.

It will now be 2 rooms so I require them to both be independent. 1 of the rooms (room 1) will have 2 switches.

I'm used to the (normal) live Neutral method however no neutrals have been used in the current setup.

Both luminares only have T+E power on a ring, no other cables. (I was expecting to see a cable leading to the switch)

I attach images of the light switches but the cables are as follows;

SWITCH / ROOM 2 (3 core+earth)
COM - Grey (hot)
L1 - Brown
L2 - Black (hot)

SWITCH / ROOM 1: (1x 3 core+earth and 3x T+E)
COM - Grey (hot)
L1 - Black + 1 Brown
L2 - 3 brown (1 shows as 230v on voltage tester)

Room/Switch 2: As this is 1 way I am going to run a new twin+earth cable from the luminar to a new switch, doing the wiring normal live neutral way. This should work?

Room/Switch 1: This room I need to remove room2s wires from this switch as currently that comes on (any idea which ones they are?) and ensure that the current room 2 switch still works in controlling this room, (keeping it 2 way for this room).

I hope that makes sense, bit in a nutshell;

Room 1 will use the existing 2 switches.

Room 2 I will run new cabling from the luminar to a new switch (changing wiring to live neutral method).

Thanks

You will need to run an additional cable from the switch in the second picture to where both lights are connected together.

Do you mean room one will still have the existing two switches?

Edit - sorry I didn't see all the text.

In that case you will need a new cable from the new switch position to the light where the supply is at present - or

to the second light position and also supply it with power.

Thanks for the info.
It's a 10 year old property, why did they wire it this way? I was taught the live neutral in the luminare way. That (to me) is logical.

I took apart a 1 way socket in a bedroom and saw they didn't use the live neutral in that either. It was 2 browns, (1 in COM, 1in L1) from 2x t+e.

Why? It just seems they have put an awful lot of cables into the light switches as opposed to the luminare.

Is this method (in my property) called something, so I can investigate further.

Either way is acceptable but it is done that way nowadays because light fittings tend not to have room for many wires.

You mean switch.
The rest is also confusing. The Neutral(s) will be used but of course not connected to the switch (which would cause a bang and release of smoke).

As above. There is room in the switch; might not be in modern luminaires.

Just "loop at switch" or "loop at light".

I was going to start the work today, can I run a T+E cable from 1 of the lights to a new 1 way socket (using the live neutral with the luminaries live) and use that in the light switch as L1, and the live in COM?
No other lights in the house use the neutral, so I'm obviously hesitant.

Switch, switch - no sockets involved.

You need to run a T&E from the light concerned to the new switch - PLUS a cable to supply power for that light; either to the light or to the switch.

(using the live neutral with the luminaries live) and use that in the light switch as L1, and the live in COM?

I do not understand your terminology.

You might be right but the words are wrong.

No other lights in the house use the neutral, so I'm obviously hesitant.

ALL lights in the house use the Neutral.

I don't think you really understand what you are doing.

Not my best diagrams but is this any clearer?

As shown in diagrams, the wires go switch to switch not light to switch, so you will need new cable from one light to a new switch, or use wireless options.

The question has to be how easy is it to run new cables? In my current house, we would need to remove the ceiling for access, but last house we had floor boards, so easier to access.

Looking for the easiest method, it would involve moving one wire in one ceiling rose, and using a smart bulb. And the best is new cable. So you need to decide if you're fitting new cable or not.

@ericmark Thanks for your tips, especially to @EFLImpudence your diagram worked wonders
