Replacing ceiling rose

[MHowell]

Hi. Looking for some guidance please as I’m wanting to replace a ceiling rose fitting into a ceiling pendant. Done this many times but never come across a ceiling rose with so many wires. What should go where please? The rose has blue, red, black, brown and yellow/green and the new light has 1 junction box with 3 places for L, E and N wires. Thanks.

A photo of the existing connections would help.

(Edit the photo smaller so the forum server allows it to upload)

Here you go. This is the ceiling rose. Thank you.

make the three lives common with a wago then bring one of the lives that you made common down to the switch to l1 then from common of the switch give it to the live terminal of the new light, neutrals go direct to the new light might end up with a bit of cable hunting but it would be fine.
dont omit the other 2 lives those are the ones that are going of to somewhere else maybe a junction box or a next existing ceiling rose.

Disregarding the pendant drop itself, the ‘new colours’ cable looks to be an extension taking a permanently live feed to another fitting or accessory. They could also conceivably be a new feed to the entire lighting circuit but that is less likely.
Either way, it’s best thought of as a normal ceiling rose with an extra loop in/out.
Same principals as usual - identify the switch wire, set that aside, then all remaining neutrals together, all remaining lives together, fitting connected to the neutrals and one side of the switch wire, other side of switch wire to the lives.
As above you’ll need an extra wago or other connector for the permanent lives, a 5 way wago would probably be easiest for this one.

Depending on the construction of the new light, you might have to fit a new junction box into which all the existing cables terminate, with a single cable leading from there to the new light.

I'd want to find out what that bit of flex is doing before fitting a new light, it has the feel of a DIY addition to the circuit and tracing it could lead to something that needs some improvement.

Thanks. Probably best to get a sparky in then. Think this is out of my comfort zone.

It's a flex, and I doubt it has the minimum 1.0mm2 csa for fixed wiring.
