The wiring is old has 3 reds in a block 2 yellow in another separate block and 2 blue separate block with a single black this is the block the light fitting goes to any help would be greatly appreciated

To avoid death, pay someone to do it for you. It’s what I would do!

I also enjoy that there is a tag for electric and also electrics

Lol thanks for the advice, usually handy with stuff like this, but this sort of wiring is baffling

2 way switching? The colours you have said are the old 3 core cable colours (R,Y,Bl) and main cable (R,Bk)

 

[James O’s]

Yes I have a 2way dimmer which controls the 2 front room lights But now it seems only the right dimmer controls both lights and no lights anywhere else other then the new ones

Brace yourself Rodney. Brace yourself.

Is there a way I can upload a photo straight to this thread ?

you need to look up ring lighting circuits (one of the reasons I still have a couple of hefty DIY books is they come in handy for lighting circuits), but really if you're not sure then it's best to get someone in to do it, or ask a friend who is familiar with it.

Lighting is a pain in the neck as the traditional method of setting up the circuit in the UK requires 4 connector blocks in the fitting/on the ceiling and often the wiring is not easily recognisable (as depending on the install the return back to the fitting from the light switch will be the wrong colour with if you're lucky a coloured sleeve to indicated it's different).
.

Really don't touch it if you are unsure.

Yeah I’m no sparky but I can change a light or switch etc... I don’t get it though I literally disconnected the old lights from the blocks and put a new light up exactly the same and this happened.... I haven’t changed any of the wires, but when I did take the old light down a single black was loose so I assumed that went with a blue

I just saw the comment about two way fittings.
Those are an utter nightmare, I've done them a couple of times but only after taking photos and labelling every conductor individually (going back many years I did actually put one in our garage, but got a neighbour who is a sparky to look at it before finished).

Could do with an image of the wiring.

 

[James O’s]

How can I post one direct to here ?

There’s the 2 images of them

Always take pictures of the wiring before you disconnect anything, then it cant really go wrong. Often you will find the wrong colour cables, no sheathing to indicate the switched lives and so on so having a picture to look back on is ideal.

Yeah done that on the first and it was fine, but noticed on the second a single black was loose so assumed it come out when taking lights off

Do the other lights work now if you leave the wires like that?

 

[James O’s]

Nope nothing but if I put the ceiling lights back up the ceiling lights work but still nothing else
