Course Overview
Last updated April 2026The Complete Electrical Installation Diploma — Level 2 and Level 3 Combined
The Level 2 & 3 Diploma Package combines both City & Guilds 2365 electrical installation qualifications into a single enrolment. You get the Level 2 Diploma (2365-02), the Level 3 Diploma (2365-03), and a 2-day Wiring Regulations classroom course — everything you need to build a solid foundation for your electrician career, with the convenience of one enrolment and one payment plan.
Who Is This Package For?
Career changers — No prior electrical experience required. This is the most popular route for adults retraining as electricians. Many of our learners come from completely different industries and successfully qualify.
Those committed to the full pathway — If you already know you want to progress through Level 2 and Level 3, enrolling on the combined package means no gap between qualifications. You move straight from Level 2 into Level 3 while the knowledge is fresh.
Industry workers without formal qualifications — If you're already working in electrical or construction but lack recognised credentials, this package takes you from entry-level through to advanced theory in one continuous programme.
Employers upskilling their workforce — We work with companies across the UK who book this package for their employees. In-centre practical days can be scheduled flexibly around your business needs, on weekdays or weekends.
What's Included
The package includes three qualifications:
City & Guilds 2365-02 Level 2 Diploma in Electrical Installations — The UK's most recognised entry-level electrical qualification. Covers electrical science fundamentals, health and safety, wiring systems, cable installation, and the BS 7671 Wiring Regulations.
City & Guilds 2365-03 Level 3 Diploma in Electrical Installations — Advanced electrical theory including three-phase systems, fault diagnosis and rectification, inspection and testing procedures, and electrical systems design.
2-day Wiring Regulations classroom course — An intensive classroom session at our Nottingham training centre covering the requirements of BS 7671, preparing you for the electrical industry's most essential regulation.
How the Course Works
This is a hybrid course combining flexible online theory with 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 13 to 16 days at our training centre across both levels, depending on your existing practical skills. Level 2 sessions cover hands-on wiring, testing, and fault finding. Level 3 builds on this with fault diagnosis and rectification, inspection and testing procedures, and electrical systems design.
We offer unlimited training days — 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.
Exams are normally taken at the centre. If you prefer, these can also be sat remotely with online invigilation for a small additional fee.
Your Career Pathway After the Package
After completing both diplomas, the remaining steps to your JIB Gold Card are:
18th Edition Wiring Regulations (2382) — The industry-standard exam on BS 7671
Inspection & Testing (2391) — Certify and sign off electrical installations
NVQ Level 3 (2357) — Workplace-based assessment of your practical competence
AM2 Assessment — The final practical test for your Gold Card
Qualified electricians in the UK earn £35,000–£50,000+ per year, making the training investment one of the fastest-returning career decisions available.
JIB ECS Card Support
As a recognised JIB training provider, we help you apply for your JIB Trainee Electrician ECS Card from the point of enrolment — essential for working on construction sites and demonstrating your credentials to employers.
ELCAS Funding
This package 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 up to 18 monthly instalments. Pay in full and save £300 — bringing the total to £4,650.
The package awards two separate City & Guilds certificates: the 2365-02 (Level 2) and the 2365-03 (Level 3). Together they cover everything from electrical fundamentals through to advanced three-phase systems and installation design. A 2-day Wiring Regulations classroom session is also included.
Who Is This Course For?
The package is the most popular route for adult career changers who want to become electricians without an apprenticeship. Rather than booking Level 2 and Level 3 separately, the package runs both qualifications back-to-back with no gap between them — keeping your momentum going and reducing the total training time. It suits anyone starting from scratch with no prior electrical knowledge, as well as experienced workers who need both qualifications to progress to the NVQ and Gold Card. The included Wiring Regulations session gives you a head start on BS 7671 before you take the full 18th Edition course. The package uses our hybrid delivery model — online theory at your own pace combined with practical workshops at our Nottingham training centre. This gives you the flexibility to study around other commitments while still getting genuine hands-on experience in fully equipped training bays.
What This Qualification Unlocks
Completing the package gives you both Level 2 and Level 3 Diplomas — the knowledge qualifications needed to begin the NVQ Level 3 (2357), which is assessed entirely on site through your real work. From there, you complete the 18th Edition (2382), Inspection and Testing (2391), and the AM2 practical assessment to earn your Installation Electrician Gold Card. The package is the fastest classroom route to Gold Card eligibility for someone starting with no qualifications. You are eligible for a Trainee Electrician ECS card from day one of your training, allowing you to work on site under supervision while you complete the rest of the pathway.
Career and Earning Potential
The package is more cost-effective than booking Level 2 and Level 3 individually, and the continuous schedule means you can be ready for employed work sooner. Qualified electricians who complete the full pathway typically earn £33,000 to £43,000 employed or £50,000 and above self-employed. Many of our package students start earning as trainees within months of beginning the course, at around £16 per hour, while they build the on-site experience needed for the NVQ. The package gives you the strongest possible foundation for whichever direction you take your career — domestic, commercial, industrial, or specialist areas like EV charging and solar PV.

Unit 301:Understand the Fundamental Principles and Requirements of Environmental Technology Systems
<p>Unit 301 is the Level 3 introduction to <strong>micro-renewable energy and water-conservation technologies</strong> — an increasingly central part of modern electrical work as domestic solar, battery storage, heat pumps and EV charging become mainstream. You will learn the fundamental working principles of <strong>solar photovoltaic (PV), solar thermal, ground-source and air-source heat pumps, biomass, micro-wind, micro-hydro and micro-combined heat and power (mCHP)</strong>, plus rainwater harvesting and greywater re-use.</p><p>The unit covers the building-location and building-feature requirements that determine whether each technology can be installed on a given site — roof orientation and pitch for solar, wind resource for micro-wind, available head for micro-hydro, heat-loss calculations for heat pumps — and the regulatory framework that applies, including Part L of the Building Regulations, the Smart Export Guarantee and MCS scheme requirements. You will also know the typical advantages and disadvantages of each technology so you can advise clients honestly about what will and will not work for their property.</p>
