In my house the lighting circuit is made up of
One live and earth in same sheathing. Then 2 separate neutrals.
I haven’t seen this arrangement before and I’m wondering what this is.

goes back to 50's and early 60's. lights wired in singles. red/cpc for L's and blacks with no cpc for N's. this was so as to take L's to switch/es then to light/s without it being tied in to the N, which went direct to light/s. the next light would then have L from 1st switch C to C of 2nd switch etc.

At the light there’s one live and 2 neutrals so this is where I was encountering the problem. Obviously the neutral carries on to the next light but where’s the live the live that goes to the next light?! Don’t know if I’m over thinking it as I can’t work it out

the L goes to the 1st switch, then is looped from switch to switch, each switch supplying a S/L to it's light. sometimes there may be junction boxes hidden away.

So the lights aren’t in a series (daisy chain)? Sorry I’m really struggling to find a diagram online.
 
Yes seen this once before on a house built in the 1950s

Single red (imperial) with bare earth in grey sheath with a separate black at the lights

Very odd configuration and only ever seen one house wired like this

Nothing unusual about that cable.
It was in use untill at least 1988 when my house was wired from new with it.
My first house in 1972 had it as well.

if its single red (or black) with bare cpc in grey sheath, I know the number for it is 6241Y... like T&E is 6242Y

Im sure it was called "Single and Earth"... like twin and earth or 3 core and earth

it's simple.red with cpc goes into C on sw#1, the to sw#2 then sw#3 etc, each switch then feeds switched L and cpc to it's light. the N's are looped through at the lights.no need for them to go to switches, and no need for cpc on the N singles.

My house is the same, ie. Red+earth and then separate neutral. There's also a traditional round junction box in the loft which I am going replace with either DIN terminals or wagos. Mind you I've been going to sort it out for about fifteen years now.

Some areas of the UK used this method of wiring quite a lot, there is a local 'care home' wired in such a way. I used the same single and earth cable in my house to wire the switched live to all the switches that are overridden by the smoke alarms.
