Diploma in Plumbing and Domestic Heating Environmental Technologies | Level 3 Apprenticeship

The Diploma in Plumbing and Domestic Heating Environmental Technologies Level 3 Apprenticeship is designed for learners who are working as apprentices and want to develop the skills and knowledge needed for a career in plumbing and heating. It suits those who are employed in the industry and want to gain a recognised qualification while developing practical experience in the workplace.

Delivered as a day‑release programme, apprentices attend college one day per week to complete both theoretical and hands‑on training. Throughout the course, learners build a strong understanding of plumbing and heating systems, including health and safety practices and the scientific principles that underpin modern installations. Learning is closely linked to real work activities, helping apprentices apply new skills directly to their job role. 

The apprenticeship also covers environmental and renewable technologies, reflecting the changing demands of the industry. Apprentices develop skills in areas such as air source heat pump systems and solar thermal hot water systems, alongside more traditional plumbing and heating technologies. This helps learners understand how sustainable solutions are installed and maintained within domestic settings. 

By the end of the apprenticeship, learners will have developed the skills, knowledge and behaviours needed to work effectively as a plumber. The qualification supports progression within the plumbing and heating industry, providing a strong foundation for long‑term employment and career development in both traditional and environmentally focused roles.
