The 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.
ELCAS Funding
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.
Flexible Payment Options
We offer interest-free payment plans with no credit checks required. Pay a deposit to secure your place, then spread the remaining cost over manageable monthly instalments. We also offer a discount for paying in full upfront.
The City & Guilds 2365-03 Level 3 Diploma in Electrical Installations (Buildings and Structures) is a Regulated Qualifications Framework (RQF) Level 3 qualification regulated by Ofqual (number 600/5499/2). It builds on the Level 2 foundation and covers three-phase systems, fault diagnosis, and installation design — the technical knowledge required for professional electrician status and ECS Gold Card eligibility. The Level 3 is taught to the current BS 7671:2018+A4:2026 (the "Orange Book", Amendment 4) — the live UK wiring regulations standard from April 2026.
Who Is This Course For?
The Level 3 is for anyone who has completed the Level 2 Diploma (or equivalent) and wants to progress towards full electrician status. Most students take the Level 3 immediately after Level 2, either as individual courses or as part of the Level 2 and 3 Diploma Package. The Level 3 is also taken by experienced electrical workers who hold older qualifications and need to update to the current standard — and if you have 5+ years of practising experience with a Level 2, the Experienced Worker Assessment (EWA) is an alternative route that skips the 2365-03 Diploma. You must have a solid understanding of Level 2 content — electrical science, circuit types, and safe working practices — before starting.
Home Study + Online E-Learning
The theory of our Level 3 2365 Diploma is delivered 100% online as a home study e-learning course. You complete the seven mandatory units — Unit 201 (Health & Safety in Building Services Engineering, carried forward from Level 2), 301 (Environmental Technology), 302 (Principles of Electrical Science), 303 (Fault Diagnosis & Rectification), 304 (Inspection, Testing and Commissioning), 305 (Electrical Systems Design), and 308 (Career Awareness) — from anywhere in the UK, at your own pace. The online learning platform runs in any browser and has iOS and Android apps. Expect to put in around 8 hours of self-study per week. Tutor support is available by email and phone whenever you get stuck.
This home study route suits adult learners balancing full-time work, career progressors moving from Level 2 to Level 3 without stopping their current job, and learners outside Nottingham who can travel in for the practical and exam days but don’t want to commute weekly. Part of our home study electrician course range.
Fast-Track Level 3 for Experienced Workers
If you already hold a Level 2 and have been working in the trade — or if you have progressed straight from Level 2 — the fast-track Level 3 route lets you complete the full qualification in 4 to 6 months with flexible attendance. That compares to 1 to 2 years at a local college running evening classes. The difference is the online e-learning platform: you work through the units at your own pace and book practical days and written exams when you are ready, rather than following a rigid term timetable.
Important: Level 3 written exams and practical assessments are sat in person at our Nottingham centre — unlike the Level 2 online tests (which can be taken remotely with online invigilation), the 2365-03 requires in-person attendance per City & Guilds requirements. Most learners combine exam days with practical training days to minimise travel.
What This Qualification Unlocks
The Level 3 Diploma is where you move from understanding how electrical installations work to designing and diagnosing them. The course covers three-phase power systems, complex circuit design, fault diagnosis and rectification, and the principles behind inspection and testing. After completing Level 2 and Level 3, you progress to the 18th Edition Wiring Regulations (2382), 2391 Inspection and Testing, and then the NVQ Level 3 with AM2 assessment — the final steps to your Installation Electrician Gold Card. To register with a competent person scheme (NICEIC or NAPIT) for Part P self-certification, and to issue Electrical Installation Certificates, Minor Works Certificates or EICRs in your own name, you need the NVQ Level 3 plus Gold Card — the diplomas alone are not sufficient for certification authority.
Career and Earning Potential
Holding both the Level 2 and Level 3 Diplomas places you firmly on the Gold Card pathway and qualifies you for higher-paid employed roles while you complete your NVQ. The diploma is a prerequisite for Inspection and Testing (2391), while specialist courses in EV charging (2921) and solar PV now require the NVQ Level 3 as a minimum. Self-employed electricians with the full pathway completed (including NVQ and Gold Card) regularly earn £50,000 and above, with specialists in green technologies charging £300 to £500 per day. The Level 3 course is ELCAS eligible — Armed Forces personnel can access up to 80% funding towards the course fee.
