Hi all I've pulled down a chimney flue on an external wall and rebuilt in brick with a knockout box in situ for power. I've chipped off all the plaster from the wall as it looked shocking.
**My question is do I route the cable up to the knockout box on top of the brick work and plaster over (obviously using trunking) or can i feed the cable in the cavity?**
