The official framework — 87 requirements.

Every Knowledge, Skill and Behaviour below is the verbatim regulatory text of the Plumbing and domestic heating technician apprenticeship standard (v1.2). On EngTree, each one becomes a node — verified knowledge entries, training modules and End-Point Assessment evidence all map back to it. This standard has options — requirements marked with an option name apply to that pathway only.
