City & Guilds 2365 Course: Complete Guide
Everything about the C&G 2365 qualification — what it covers, how the course is structured, assessments, and what comes after.
What Is the City & Guilds 2365?
The City & Guilds 2365 Diploma in Electrical Installationis the UK's most widely recognised classroom-based qualification for aspiring electricians. It is the qualification that most adults and career changers take when entering the electrical trade through the adult diploma route.
Available at Level 2 (foundation) and Level 3 (advanced), the 2365 covers everything from basic electrical science to complex circuit design and fault diagnosis. Delivered through a combination of classroom theory sessions and hands-on practical workshops, it provides the technical knowledge foundation for a career in electrical installation.
The 2365 replaced the older 2330 and 2360 qualifications (see our Level 2 vs Level 3 comparison) and is the current standard diploma for the trade. Whether you are a complete beginner or someone with related experience looking to formalise your skills, this guide gives you a complete overview — the course structure, what you will learn at each level, how Total Skills delivers it, how you are assessed, and the full pathway to becoming a qualified electrician.
Who Is the 2365 For?
The 2365 is designed for anyone who wants to become an electrician through the diploma route rather than a traditional apprenticeship. It is the primary qualification for adult learners and career changers — people who cannot or do not want to spend 3 to 4 years in an apprenticeship.
Typical 2365 learners
- ✓Career changers in their 20s, 30s, 40s, or 50s looking for a more rewarding trade
- ✓Adults who missed the apprenticeship window and want to retrain
- ✓People in related trades (plumbing, gas, carpentry) adding electrical skills
- ✓Armed forces leavers transitioning to civilian careers (ELCAS funding may apply)
- ✓Anyone seeking a profession with genuine job security and strong earning potential
There is no upper age limit for the 2365. We regularly train people of all ages. There are no formal academic entry requirements for Level 2 — you do not need GCSEs, A-levels, or a degree. A basic understanding of maths (fractions, percentages, and simple algebra) is helpful, but the course teaches the electrical calculations you need in context.

How Total Skills Delivers the 2365
At Total Skills, we deliver the 2365 through a hybrid learning model that combines online theory study with practical workshops at our training centre. This approach is designed for adult learners who need flexibility — you can study theory around your existing commitments and attend workshops on scheduled days.
Online theory
The theory component is delivered through our online learning platform. You work through structured modules covering electrical science, regulations, and installation theory at your own pace. The content includes video tutorials, reading materials, practice questions, and regular progress checks. You can study in evenings, weekends, or whenever suits your schedule.
Practical workshops
Practical skills are taught in hands-on workshops at our Nottingham training centre (Arnold, NG5 7ER). These sessions are where you learn to wire circuits, bend conduit, install containment systems, and work in realistic training bays. Workshops are scheduled on specific days so you can plan around work or other commitments. Weekend options are available.
Why hybrid works for career changers
- ✓Study theory online around your current job — no need to quit work immediately
- ✓Attend practical workshops on scheduled days, including weekend options
- ✓Progress at a pace that works for your circumstances
- ✓Access tutor support throughout your studies, not just during workshop days
- ✓Reduce travel time and costs compared to full-time, centre-based courses
Practical work cannot be done remotely
Level 2 in Detail
The Level 2 Diploma is designed for complete beginners. It starts from first principles and builds your understanding progressively across 14 to 16 weeks of study.
What you will learn
Level 2 covers the fundamentals that every electrician needs. You will learn what electricity is, how circuits work, the principles of AC and DC power, and the safety legislation that governs the industry. By the end, you will be able to install basic wiring systems, work safely on electrical circuits, and understand the theory behind what you are doing.
Typical weekly breakdown
The Level 2 is structured around a mix of online theory study and practical workshop sessions. The balance shifts towards more practical work as the course progresses and you begin applying the theory you have learned.
What the practical workshops involve
- ✓Working in dedicated training bays that simulate real installation environments
- ✓Running cables through conduit, trunking, and cable tray
- ✓Wiring ring final circuits, radial circuits, and lighting circuits
- ✓Connecting accessories: sockets, switches, light fittings, consumer units
- ✓Bending conduit and working with different containment systems
- ✓Timed practical assessments under exam conditions

Level 3 in Detail
The Level 3 Diploma takes approximately 16 to 20 weeks and assumes you already understand the fundamentals covered at Level 2. The pace is faster and the content is significantly more demanding.
Key areas of increased difficulty
- ✓Cable sizing calculations using BS 7671 tabulated data and correction factors
- ✓Voltage drop calculations for long cable runs
- ✓Fault current calculations and protective device coordination
- ✓Three-phase power systems: star and delta configurations, phase voltages
- ✓Complex distribution board design with diversity calculations
- ✓Systematic fault diagnosis using half-split and other techniques
The maths at Level 3 is considerably more challenging than Level 2. You will need to be comfortable with algebra, using formulas, and working with tables from BS 7671. If maths is not your strongest area, extra revision time will be needed. See our electrical exam tips guide for revision strategies.

Level 2 vs Level 3: What Is the Difference?
This is one of the most common questions we get asked. The short answer: Level 2 teaches you how to install electrical systems. Level 3 teaches you how to design, diagnose, and manage them. You need both to become a qualified electrician.
Scope
Level 2 focuses on the practical skills of installation — wiring circuits, running cables, connecting accessories, and understanding basic electrical science. Level 3 moves into design principles, fault diagnosis, three-phase systems, and the more complex calculations needed for commercial and industrial work.
Difficulty
Level 2 is achievable for anyone willing to study consistently, even with no prior electrical knowledge. National pass rates sit at approximately 80 to 90 percent. Level 3 is a significant step up. The maths is harder, the concepts are more abstract, and the practical assessments are more complex. Pass rates are around 70 to 85 percent.
Duration
Level 2 takes approximately 14 to 16 weeks. Level 3 takes 16 to 20 weeks. If you enrol on the combined Level 2 and 3 package, you can complete both back-to-back in approximately 30 to 36 weeks.
Career value
Level 2 alone qualifies you to work as an electrical mate or trainee installer. To become a fully qualified electrician and progress towards your ECS Gold Card, you must complete Level 3. Most employers require both Level 2 and Level 3 for installation roles.

Tips for Success on the 2365
The 2365 is demanding but achievable with the right approach. Here are practical tips from learners who have completed it successfully:
- ✓Attend every session — the course moves fast and gaps in attendance create gaps in knowledge
- ✓Practise calculations daily — Ohm's law, power formulas, and cable sizing become second nature with repetition
- ✓Use the workshop time well — wiring speed and accuracy improve dramatically with practice
- ✓Form a study group — discussing concepts with classmates helps everyone understand better
- ✓Ask questions in class — if something is unclear, ask immediately rather than falling behind
- ✓Start a formula sheet — write down every formula as you encounter it and revise it regularly
- ✓Do past papers — practice with previous exam questions if your provider makes them available
- ✓Do not cram — consistent daily study of 1 to 2 hours is far more effective than marathon sessions before exams

Common Questions from Career Changers
If you are considering the 2365 as a career change, you are not alone. The majority of our learners are adults retraining from other careers. Here are the questions they ask most often.
Is there an age limit?
No. There is no upper age limit for the 2365 or for working as an electrician. We train people from their early 20s to their late 50s. The adult diploma route exists specifically for people who are past the traditional apprenticeship age. Your maturity and life experience are genuinely valued by employers.
What maths do I actually need?
You need to be comfortable with basic arithmetic, fractions, percentages, and simple algebra. At Level 2, the maths is straightforward — Ohm's law (V = I x R) and basic power calculations. At Level 3, it gets harder with cable sizing, voltage drop, and fault current calculations, but the course teaches you these formulas in context. You do not need A-level maths. If you can calculate a percentage and rearrange a simple formula, you will manage.
Do I need to be physically fit?
Reasonably fit, yes. Electrical work involves standing for extended periods, lifting tools and materials, working in roof spaces and under floors, and sometimes working at height or in confined spaces. It is less physically demanding than trades like bricklaying or roofing, but you need to be mobile and able to do manual work.
Can I keep my current job while studying?
Yes, and many career changers do exactly this. With hybrid delivery, you study theory online around your existing schedule and attend practical workshops on specific days. Some learners reduce to part-time work during training, while others manage the course entirely around full-time employment. It requires commitment, but it is designed to be achievable.
Will employers take me seriously without an apprenticeship?
Yes. The diploma route produces the same City & Guilds qualifications and the same ECS card as an apprenticeship. Employers and the JIB recognise both routes equally. In fact, many employers prefer hiring career changers because of the transferable skills they bring — reliability, communication, problem-solving, and professionalism.
For a complete guide to making the switch, see our career change to electrician guide.
What Comes After the 2365?
The 2365 Level 2 and Level 3 diplomas give you the technical knowledge, but they are not the end of the journey. To become a fully qualified electrician and obtain your ECS Gold Card, you need additional qualifications. Here is the full pathway with realistic timelines.
Step 1: 18th Edition Wiring Regulations (2 days)
The 18th Edition (C&G 2382-22) is mandatory knowledge of BS 7671, the wiring regulations that govern all electrical work in the UK. Many learners take this during or immediately after their Level 3 Diploma, while the knowledge is fresh.

Step 3: ECS Blue Card (Registered Electrician)
Once you hold the Level 2 and 3 Diplomas, 18th Edition, and 2391, you can apply for the Registered Electrician (Blue) ECS card. At this point you are recognised as a qualified electrician and can work on most sites and projects.
Step 4: NVQ Level 3 and Gold Card (6 to 12 months)
The NVQ Level 3 (C&G 2357) is an on-site competence assessment completed while you are working. An assessor visits you on site, reviews your evidence portfolio, and conducts professional discussions. After completing the NVQ, pass the AM2 assessment and apply for your ECS Gold Card. This is the highest level of qualification for an installation electrician.

Realistic timeline
From starting Level 2 to holding your Gold Card, expect approximately 18 months to 3 years depending on your pace and circumstances. You can start earning as an electrical worker after completing Level 2 (within 4 months of starting). You do not need to wait until you are fully qualified to begin working in the trade. For the full pathway overview, see our electrician qualifications explained guide.
Specialisations After Qualifying
Once you hold your core qualifications, you can add specialist skills that increase your earning potential and open up new market sectors. The 2365 is the foundation that makes all of these accessible.
- ✓EV charger installation (C&G 2921) — the fastest-growing specialism in the trade
- ✓Solar PV and battery storage — renewable energy installations
- ✓Fire alarm systems — commercial and domestic fire safety
