Apprenticeship Level 6 - Building Services Mechanical - Cardiff (6050)

Our Level 6 Degree Apprenticeships

Our apprenticeships allow you to study for industry‑recognised qualifications while earning a competitive salary. As an apprentice, you will study with a training provider, such as a university, and combine this experience with real responsibilities in the workplace. Your study pattern could be day or block release, or via distance learning, depending on the course you enrol in. A dedicated mentor will guide you through your personal and professional development. Level 6 Degree Apprenticeships typically last 3–6 years, during which you will attain both a professional and academic qualification to further your career. Our apprentices are employed on a permanent basis, so you’ll continue to progress with Arup once you’ve completed your course.
