What Qualifications Do You Really Need to Become an Electrician?

There is a lot of misleading information about what you need to become a qualified electrician. Some training providers suggest that a short course and a couple of certificates will get you working independently. Others imply that the 18th Edition alone is enough to call yourself an electrician. None of this is true.

This guide sets out the actual requirements defined by the Electrotechnical Assessment Specification (EAS), managed by TESP. Be sure to also read our guide to spotting rogue training providers before choosing where to study. The EAS is the single standard followed by every competent person scheme (NICEIC, NAPIT, ELECSA, Stroma) and is the basis for the ECS gold card. If your qualifications do not meet the EAS, you cannot join a scheme, self-certify Part P work, or hold a gold card — regardless of what any training provider tells you.

The EAS defines five categories of qualification that are required for full electrician status. All five are mandatory. Missing any one of them means you do not meet the standard.

1. Level 2 Diploma in Electrical Installations (City & Guilds 2365)

The Level 2 Diploma is the foundation. It covers electrical science, health and safety, wiring systems, installation methods, and the principles of electrical installation. This qualification proves your understanding of the fundamentals.

Duration: typically 14 to 16 weeks full-time. Assessed through written exams, online tests, and practical workshop assessments.

2. Level 3 Diploma in Electrical Installations (City & Guilds 2365)

The Level 3 Diploma builds on Level 2 with advanced electrical theory, electrical design, fault diagnosis, three-phase systems, and inspection principles. It is a prerequisite for the Level 3 Diploma that Level 2 is completed first.

Duration: typically 14 to 16 weeks full-time. Assessed through written exams and practical assessments.

3. 18th Edition Wiring Regulations (City & Guilds 2382)

The 18th Edition qualification proves your knowledge of BS 7671, the UK standard for electrical installation. Every practising electrician must hold a current edition of this qualification. When the regulations are updated, you must update your certificate.

Duration: typically 1 week (full-time classroom) or online self-study options. Assessed by a 2-hour online exam.

18th Edition (2382)

The 18th Edition is mandatory for all practising electricians and scheme membership.

4. Inspection and Testing (City & Guilds 2391)

The 2391 qualification proves you can inspect and test electrical installations to the standard required for issuing Electrical Installation Certificates (EICs) and Electrical Installation Condition Reports (EICRs). This is essential for self-employment and scheme membership.

Duration: typically 2 to 3 weeks full-time. Assessed through a written exam and a practical assessment on a live installation.

5. NVQ Level 3 with AM2 (City & Guilds 2357)

The NVQ Level 3 is the on-site competence qualification. Unlike the diplomas (which are classroom-based), the NVQ is assessed through observation and evidence of your real electrical work on actual installations. An assessor visits you on site and evaluates your practical skills, working methods, and safety practices.

The AM2 is a standalone practical assessment taken at a dedicated assessment centre. It tests your ability to install, test, and commission a small electrical installation under timed, exam conditions. The AM2 is the final practical gate.

NVQ Level 3 (2357)

The NVQ with AM2 proves you can do the work on real sites — the final step to your gold card.

Before September 2021, some competent person schemes accepted alternative qualifications such as certificates of competence or condensed short courses. This led to complaints about the quality of work being self-certified, and in 2021 the EAS was updated to close these loopholes.

What Changed in September 2021

• ✓Certificates of competence are no longer accepted by any competent person scheme
• ✓Short courses that do not include the full diploma content are not accepted
• ✓All schemes now follow the same EAS specification — no scheme accepts lower qualifications
• ✓The full diploma route (Level 2 + Level 3) is the minimum classroom qualification
• ✓The NVQ with AM2 is required to prove on-site competence

This means that if you completed a short course or certificate of competence before 2021 and were able to join a scheme, that route is no longer available to new entrants. The industry has standardised on the full qualification pathway.

Myth: The 18th Edition makes you a qualified electrician

The 18th Edition is one of five required qualifications. It proves your knowledge of the wiring regulations but does not demonstrate practical installation skills or on-site competence. You cannot join a scheme or get a gold card with the 18th Edition alone.

Myth: You can become qualified in a few weeks

No legitimate qualification pathway can be completed in a few weeks. The Level 2 Diploma alone takes 14 to 16 weeks. The full pathway — Level 2, Level 3, 18th Edition, 2391, and NVQ with AM2 — takes 12 to 24 months at an accelerated pace. Any provider claiming you can qualify faster is either not delivering the full qualification set or is misrepresenting what their course achieves.

Myth: Experience can replace qualifications

The Experienced Worker Assessment (EWA) route exists for experienced electricians, but it still requires the 18th Edition, 2391, and AM2E assessment, plus a minimum of 3 to 5 years documented experience. Experience alone, without any qualifications, is not sufficient for competent person scheme membership.

Myth: Some schemes accept fewer qualifications

All government-approved competent person schemes follow the same EAS specification. NICEIC, NAPIT, ELECSA, and Stroma all require the same qualifications. No scheme offers a lower entry requirement. If a training provider claims their course is “accepted by” a particular scheme, verify this directly with the scheme.

Myth: You do not need the NVQ if you have the diplomas

The diplomas (Level 2 and Level 3) prove theoretical and workshop competence. The NVQ Level 3 proves on-site competence through assessment of real work. Both are required. The NVQ cannot be done in a classroom — it requires evidence from actual electrical installations on real sites.

Each of the five required qualifications tests a different aspect of competence. This is why all five are needed — no single qualification covers everything.

• ✓Level 2 Diploma: foundational theory, basic installation principles, health and safety
• ✓Level 3 Diploma: advanced theory, electrical design, fault diagnosis, three-phase systems
• ✓18th Edition (2382): knowledge of the current wiring regulations (BS 7671)
• ✓2391 Inspection and Testing: ability to inspect, test, and certify installations
• ✓NVQ Level 3 with AM2: on-site practical competence assessed on real installations

Together, these five qualifications demonstrate that you have the theoretical knowledge, regulatory understanding, testing ability, and practical skills to work safely and competently as an electrician. This is why the EAS requires all of them — removing any one would leave a gap in the competence evidence.

While there is some flexibility in when you take each qualification, the recommended and most logical order is:

• ✓Step 1: Level 2 Diploma (2365) — the foundation that everything else builds on
• ✓Step 2: Level 3 Diploma (2365) — requires Level 2 as a prerequisite
• ✓Step 3: 18th Edition (2382) — can be taken alongside or after the diplomas
• ✓Step 4: 2391 Inspection and Testing — benefits from having the diploma knowledge first
• ✓Step 5: NVQ Level 3 (2357) with AM2 — requires you to be working on real installations

Some providers offer package courses that combine the Level 2 and Level 3 Diplomas for a more efficient schedule. The 18th Edition and 2391 can often be slotted in between or after the diploma courses. The NVQ is typically completed last because it requires you to be working on real sites.

Once you hold all five qualifications, you can:

• ✓Apply for your ECS gold card — the industry-standard proof of full competence
• ✓Join a competent person scheme (NICEIC, NAPIT, ELECSA) to self-certify Part P work
• ✓Work as a fully qualified electrician on domestic and commercial installations
• ✓Issue your own Electrical Installation Certificates (EICs) and EICRs
• ✓Set up your own electrical business with full professional credibility
• ✓Work on any construction site that requires a valid ECS card

Without all five qualifications, none of these things are available to you. For a full breakdown of what electrician qualifications you need, see our overview guide. This is why it is essential to choose a training provider that delivers the genuine qualifications and is honest about the full pathway from day one.
