Electrical Installation City & Guilds Level 3 Diploma

Building on the skills you have learned at Level 1 and 2, this course can help you to further develop the competencies and knowledge you need to work in the electrical installation industry. You will study advanced techniques and delve deeper into the theory behind them. Whilst this qualification alone will not make you a qualified Electrician, many students go on to complete an apprenticeship or NVQ alongside employment.

About the Course

The Level 3 Diploma in Electrical Installation will help you to further develop the skills and knowledge learned at Levels 1 and 2, as well as providing you with an advanced knowledge of the electro-technical industry. 

Approximately 70% of the course is theory based, and 30% is practical. Theory and contextual work will be completed in a classroom setting, which allows you to take notes, which can aid you in your learning and practical execution. Your practical work will take place in a custom-built workshop, to enable to you master the skills required for Level 3. 

There is an expectation that students will work independently outside of college time on a project relative to the course. 

You will also be required to study Functional Skills/GCSE English and Maths if you do not already hold a grade C at GCSE/equivalent, as many universities and employers will require at least a grade C in both English and Maths. These skills will also be essential for your professional career as an electrician, particularly if you wish to set up your own business. 

It is important to note that whilst this course leads to the basic qualification required to be an electrician, this course alone does not qualify you to work as an electrician. In order to do this you will need to gain practical work experience through a recognised apprenticeship programme.
