Just in the dying weeks of our extension build and the plumber is
fitting his electrical bits. He's about to bury the 5 core *flex*
(not solid core cable) for the thermostat in the wall plaster, but
I've got in mind that this is a no-no. However, having thought that
thought I can't find any reference to it being prohibited in the 16th
edition on site guide.
Anyone with any references as to why that is not acceptable?
