About this course

Level 3 Electrical Installation Advanced Technical Diploma in Harrow. Classes run at Harrow College, full-time during the day. Tuition fees may apply, though funding may be available depending on your circumstances. This electrical installation advanced technical diploma course runs for 34 weeks and builds the underpinning knowledge needed for work in the building services industry. It is not the final step to becoming a fully qualified electrician, but it supports employment and prepares you for the NVQ you will need to complete that route. The City and Guilds level 3 electrical installation advanced technical diploma qualification covers both theory and practical knowledge across electrical systems.

Who this course is for

For learners who want to work as an electrician in the building services industry. This qualification does not make candidates fully qual;ified electricians but provides underpinning knowlege that will contribute to employment or further training for completion of NVQ.

What you will learn

  • You'll develop knowledge of electrical installation principles and theory.
  • You'll learn how electrical circuits are designed, installed, and tested.
  • You'll study health and safety regulations relevant to electrical work.
  • You'll cover the wiring regulations that govern electrical installations in the UK.
  • You'll gain understanding of electrical science and its application in building services.
  • You'll learn how to inspect and test electrical installations.
  • You'll build knowledge of fault diagnosis in electrical systems.

How you will learn

You'll learn through classroom-based teaching at Harrow College, combining theory lessons with practical work. Assessment is through a mix of written assignments, practical tasks, and end-of-unit assessments. You'll be assessed on both your knowledge of electrical principles and your ability to apply them. The course is delivered full-time during the day over 34 weeks.

What you will need to bring

The centre will provide most materials. Harrow College will confirm anything else you need before you start.

Where next

Jobs you could do

  • Electrical installer trainee, working toward full qualification
  • Electrical labourer, supporting qualified electricians on site
  • Building services operative, assisting with electrical fit-out work
  • Apprentice electrician, combining work and further training
  • Electrical maintenance assistant, supporting maintenance teams

What you could study next

This qualification builds the knowledge base for further training. The natural next step is an NVQ Level 3 in Electrical Installation, which is required to work as a qualified electrician. You could also progress to an Electrical Installation Apprenticeship, which combines on-the-job training with the NVQ. Completing the NVQ route leads to eligibility for a JIB Gold Card, the industry standard for qualified electricians in the UK.
