What's Included
Course Overview
Last updated April 2026The Next Step on Your Electrician Journey
The City & Guilds 2365 Level 3 Diploma in Electrical Installations builds on your Level 2 foundation, taking you into advanced electrical theory and hands-on practical skills. This is the second essential qualification on the pathway to becoming a fully qualified electrician with your JIB Gold Card.
Who Is This Course For?
Level 2 graduates — If you've completed the 2365 Level 2 Diploma (or equivalent such as 2330 Level 2 or 2360 Part 1), this is your natural next step.
Career changers progressing through the pathway — Many of our learners started with no electrical experience at Level 2 and move straight into Level 3 to maintain momentum.
Industry workers formalising their qualifications — If you're already working in electrical but need Level 3 to progress towards your NVQ and Gold Card.
Employers upskilling their workforce — We work with companies across the UK who book this course for their employees. In-centre practical days can be scheduled flexibly around your business needs, on weekdays or weekends.
How the Course Works
This is a hybrid course combining flexible online theory with intensive hands-on practical training at our Nottingham centre. Study the theory units at your own pace through our online learning platform — available 24/7 on desktop, or via our mobile app for iOS and Android, with no live sessions to attend. When you're ready, book your in-centre practical days at times that suit you.
In-Centre Training & Assessments
You'll need approximately 8 to 9 days at our training centre, depending on your existing practical skills. Level 3 practical work is more intensive than Level 2, covering fault diagnosis and rectification, inspection and testing procedures, and electrical systems design. We offer unlimited training days, so you can attend as many sessions as you need until you feel fully confident, at no additional cost.
In-centre days are available on both weekdays and weekends, giving you complete flexibility to fit training around work or other commitments. For employers booking multiple employees, we can arrange group sessions on dates that work for your team.
The course includes multiple-choice exams which are normally taken at the centre. If you prefer, these can also be sat remotely with online invigilation for a small additional fee.
What You'll Learn
The course covers advanced topics including three-phase electrical systems, power factor correction, and harmonics. You'll develop expertise in fault diagnosis and rectification, learn inspection and testing procedures to BS 7671 standards, and understand how to design electrical installations for domestic, commercial, and industrial environments. You'll also learn to complete and interpret electrical installation certificates, condition reports, and minor works certificates.
Inspection & Testing Skills
A key component of Level 3 is comprehensive training in initial verification and periodic inspection procedures. You'll use industry-standard test equipment including multifunction testers and insulation resistance testers, gaining the practical competence that employers and industry bodies require.
Your Career Pathway
After completing Level 3, you're ready for the City & Guilds 2357 NVQ Level 3 — the workplace-based qualification that, combined with the AM2 assessment, leads to your JIB Installation Electrician Gold Card. This is the standard route for career changers and new entrants to become fully qualified electricians.

Frequently Asked Questions
What are the entry requirements for the Level 3 Diploma?
You must hold the City & Guilds 2365 Level 2 Diploma in Electrical Installations (or equivalent such as 2330 Level 2 or 2360 Part 1). A good standard of English and basic maths is also required. You must be 18 or over to enrol. If you are close to completing Level 2, contact us to discuss early enrolment options.
How many days will I need to attend the training centre?
Most learners need between 8 and 9 days at our Nottingham centre, depending on their existing skill level. Level 3 practical work is more intensive than Level 2, covering fault diagnosis, inspection and testing, and systems design. We offer unlimited training days — you can attend as many sessions as needed until you feel fully confident, at no extra cost. Sessions are available on both weekdays and weekends.
How long does the Level 3 course take to complete?
Most learners complete the course in 4 to 8 months, with the average being around 5 to 6 months. The online theory is entirely self-paced, so you can study around work or family commitments. Your in-centre practical days are booked when you're ready.
Will I be a fully qualified electrician after Level 3?
The Level 3 Diploma is the second essential qualification on your pathway. After completing both Level 2 and Level 3, you need the City & Guilds 2357 NVQ Level 3 — a workplace-based qualification requiring evidence of on-site experience. Once you hold all three qualifications, you can take the AM2 assessment and apply for your JIB Installation Electrician Gold Card.
How does the hybrid online learning work?
You complete all theory content through our online learning platform at your own pace — available 24/7 on desktop or via our mobile app for iOS and Android, with no live sessions to attend. Our expert tutors provide one-to-one support via phone, email, and video call. When you're ready for practical training, you book in-centre days at times that suit you.
What payment options are available?
We offer interest-free payment plans with no credit checks. Pay a deposit to secure your place and spread the rest over monthly instalments. We also offer a discount for paying in full upfront. Employer-funded and company invoicing available on request.
Can my employer book this course for me or my team?
Absolutely. We work with companies across the UK who fund training for their employees. We can arrange group sessions on dates that work for your team, including weekends. Contact us to discuss employer bookings and group pricing.
Is this course eligible for ELCAS funding?
Yes. This course is eligible for ELCAS (Enhanced Learning Credits) funding for serving and former Armed Forces personnel. Total Skills is an approved ELCAS provider (Provider Number: 12999), offering up to 80% financial support. You must have completed at least 4 years of service to be eligible. Contact us for help with your application.
What practical training is included?
The course includes intensive hands-on practical training at our fully equipped Nottingham centre. You'll cover fault diagnosis and rectification, inspection and testing procedures using industry-standard equipment, and electrical systems design. Your practical assessments are also completed at the centre. We offer unlimited training days so you can practise until you're confident.
What happens after I complete Level 3?
You receive your City & Guilds Level 3 Diploma certificate and can progress to the NVQ Level 3 (2357) — the workplace-based qualification that leads to your JIB Gold Card. Many learners are already working on-site with their ECS card while completing Level 3, so they can begin gathering NVQ evidence straight away.
When can I start?
Straight away! As soon as your enrolment is confirmed and payment or deposit is received, you get instant access to the online learning platform. There's no waiting for a term or cohort to begin — you can log in and start studying the same day. Many of our learners begin in the evening after enrolling that morning.
Is the Level 3 Diploma worth the investment?
The Level 3 is required for the NVQ, AM2, and Gold Card — without it you cannot become a fully qualified electrician or register with NICEIC/NAPIT. At £2,650, the cost is recoverable within the first few months of qualified work at £35,000–£45,000 per year.
