UK Rewire using old conduits

[Welsh_sparky_21]

Rewiring a house in a few weeks, the lighting circuit is wired in old conduits. Interested to know if you would re use the conduits or just do new chases for the cables

Also you are running insulated and sheathed cable in the tube so 'double insulated' for want of a better phrase

If you were pulling singles through the old tube then I would want to see it bonded

If it's a conduit drop to the switch then it will be in a prescribed zone.

And the cables are insulated and sheathed (twin and earth), not singles.

As mentioned previously, there will be a fitting on the conduit at the top of the switch drop (a tee or an elbow) that you can remove with a screwdriver. There used to be rubber bushes available to go over the end of the slip tube, but not sure if these are still being sold.

I'd wire it using a central junction box either under the hallway floor with maintenance free connections or somewhere accessible.

When we did rewires using the old tube we used to put a big JB in the airing cupboard / loft / broom cupboard

1 cable at the switch , 1 cable at the light was quite nice when it came to 2nd fix
