Course Overview

The Level 3 Advanced Technical Diploma in Plumbing is designed for learners who have already achieved a Level 2 plumbing qualification (such as City & Guilds 6035-02) and who want to deepen their technical understanding of plumbing systems and design. It develops theoretical knowledge, system planning skills and technical understanding relevant to modern plumbing and building services engineering. These skills support progression toward further industry qualifications, apprenticeships or technical roles in plumbing and heating.

For this course you will need steel toe-capped safety footwear – required for workshop sessions, protective workwear such as overalls or durable work trousers, safety glasses and gloves (as specified by the training centre), tools & stationery, tape measure (e.g., 5 m builder’s tape), notebook or notepad for lectures and portfolio planning, pens, pencils, and scale ruler, folder or ring binder to organise coursework, assignment work and notes.
