Help replacing faulty dimmer switch

[MJPD29]

There's a good chance that cable will be badly degraded be very careful when handling it

meanwhile, just to get the light working, I'd change that pattress for a deeper one, carefully attach ( using block connectors or wagos) some 1.0mm flex to the existing cables and then connect into the dimmer. does look like a rewire is needed tough.

Think I would make rewire 1st priority

I suggest you get some insulation tape and wrap it around the excess conductor that is visible. .

I think it needs more than that to be honest, that is a car crash there, tape is not enough, it is a complete mess.

I concur, that's why I went on to say....

"If this is your house, I would advise you consult a local electrician with a view to having the installation inspected. That appears to be cloth covered wiring which in an ideal world shouldn't be in service."

It saddens me but I have to agree to some extent
