Joining cables in wall

[essex123456]

i have a bathroom fan and the isolator switch was placed next to the light switch. Which looks awful. I want to put the isolator above the door instead. But the cables are to short. How can I join the cables to extend them? I have read they can be crimped and sleeved, but I do not have the tool for that. Can they be joined in a connector box? Such as

Thanks

Yes, that will be alright if you can get at it afterward - not buried in the wall.

Thanks, what do you do if you do want it buried in the wall? Can I solder and heat shrink?

Yes but the soldered joint should be a good one. Also bear in mind safe zones or mark it in some way such as a blanking plate on the surface.

Heat shrink etc omitted to show the soldered joint clearly.

It's not really an 'or'. One should adhere to 'safe zones', and it's possible that one could create a safe zone by using a blanking plate - but there is debate as to whether a blanking plate (as opposed to some accessory to which cables are connected) actually does create a 'safe zone' (essentially because it easily be removed). A blanking plate is certainly 'better than nothing', but I'm personally not at all sure that its actually a regs-compliant way of creating a 'safe zone'

I can't help thinking the cables would run down the wall, and could be re-routed without joining them.

No they come through the wall at the level of the switches, I don't want the isolator next to the light switch as it looks crap. Hence I want to move the isolator above the door. But to do that I need to extend the cables.

From where?

 

[sparkwright]

Can you join the cables within the light switch box??

 

[essex123456]

From where?

They run down the safe zone on the other side, and then go through the wall the wall is tiled in the bathroom. There is also a false ceiling, but I can't get to the wires from inside the room. I could leave the isolator where it is but it looks rubbish.

They run down the safe zone on the other side,...

What is creating the safe zone on the other side?

It could be the the switch on this side.

We haven't asked how this isolator is wired.

I, at least, have assumed it is a three-pole isolator but does it isolate the light as well.
How is the fan controlled? By this switch or by the light?

Why not do away with the "isolation" part and just swap it for an ordinary switch that controls the fan - in one way or another?

 

[JohnW2]

It could be the the switch on this side.

It could, but we oibviously don't know.

The concern in the back of my mind was that it could be possible that the cable on the other side was allegedly 'borrowing' a safe zone created by something entirely different - which is, of course, not allowed (because the 'something entirely different' could be removed in the future).
