Two way lighting not working

[peter m]

Are you saying one of the wires that was originally taped up lights up your voltage sensor ,and no other wires do ?
You would be better off buying a multimeter ,those volt sticks are not gonna be much use to you for fault finding.
Yes ,it's possible that pulling on wires could cause a disconnection. So could many other things ,hence me asking the questions below.

That remain unanswered.

No issues with ceiling rose all connections secure

No issues with ceiling rose all connections secure

Is that the ceiling rose connected to the switches in question?
If so ,is the permanent live to the switches fed from that rose ?

 

[peter m]

No idea but it must be if those switches operate the light , I'm not a spark so guessing

Pictures of the wiring connections at the rose may be useful.
If the permanent live to the switch originates there,that would be a starting point,followed by tracking the cable in the loft. Hopefully it's not boarded over up there and you can access the cables !

I got a loft conversion

Oh sheeite !!
The switch cable appears to come from the rose, fairly standard loop In wiring.

Very helpful NOT

If that’s an example of the standard of the electrics in your house I would recommend you get it tested and inspected thoroughly.

Would you rather people didn’t suggest recommendations?
