Supply cable up through cavity.

[epsilonGreedy]

I am planning to route my mains supply cable up through the cavity to the cavity wall embedded meter box. This cable will enter the cavity 450mm below ground and then rise vertically 1.2m up to the base of the in wall meter box.

 

A technical diagram showing how to do this mentions a 38mm conduit for the cable within the cavity. Does this conduit need to be armoured?

No - it’s 38mm PVC or fiberglass depending on the DNO

Ask your DNO for their specification.  It's normally white or black plastic with a bend formed at the bottom, and known as a "hockey stick" due to it's shape.

Probably not worth the hassle of couriering, but I've got an unused white one you can have if you happen to be passing this way...
