City & Guilds 2365 Level 2 & 3 Electrician Diploma Package

Unit 201 gives you the health and safety foundation every working electrician needs on site. You will learn the roles and responsibilities set out in the Health and Safety at Work Act, the Electricity at Work Regulations, PUWER, COSHH, Working at Height, Manual Handling, PPE and Control of Asbestos at Work Regulations — the statutory framework that governs every electrical job in the UK.

The unit covers safe isolation procedures, risk assessments and method statements, permits to work, PPE selection, and the procedures for dealing with accidents including electric shock, burns and fires. You will learn to identify hazards on real installations — including asbestos in decorative finishes, fuse-carrier flash guards and distribution-board matting — and the CLP pictograms for hazardous substances, correct fire-extinguisher selection and RIDDOR reporting.

Unit 202 is the science foundation that underpins every other unit on the Level 2 Diploma. You will cover the mathematical principles used in electrical work — fractions and percentages, algebra, indices, transposition, triangles and trigonometry — and the SI units used for measuring electrical quantities including resistance, voltage, current, power, energy, impedance, inductive and capacitive reactance, and power factor.

The unit builds up from Ohm's law and series and parallel DC circuits through to mechanics (force, work, energy, power, levers), magnetism and electromagnetism, and the generation of AC supplies — including sine-wave characteristics such as RMS value, peak-to-peak, periodic time, frequency and amplitude. You will also learn about the electronic components used in modern electrical systems: capacitors, resistors, diodes, LEDs, thermistors, transistors, thyristors and invertors — and how they appear in security alarms, dimmer switches, heating controls, motor control and wireless control systems.

Unit 203 is the "how electrical installations work" knowledge unit. You will learn the statutory regulations that govern the trade (HASAWA, EAWR, ESQCR, PUWER, COSHH, CDM) and the non-statutory guidance documents — BS 7671 (the current Amendment 4 "Orange Book"), the IET On-Site Guide, the IET Guidance Notes and industry Codes of Practice — and how to use each to specify and install compliant systems.

The unit covers wiring systems for domestic, commercial, industrial, hazardous and agricultural environments: ring final and radial circuits, cable tray, ladder racking, cable conduit (steel and PVC), cable trunking, steel-wire armoured, MICC and fire-resistant cables. You will learn the UK earthing systems (TT, TN-S, TN-C-S/PME), Automatic Disconnection of Supply (ADS), circuit protective conductors (CPC), main and supplementary bonding, earth-loop impedance terms (Zs, Ze, R1, R2) and the main earthing terminal (MET). The unit also covers how electricity is generated and distributed through the national grid from 400 kV transmission down to 400/230 V distribution, plus an introduction to micro-renewable technologies including solar PV, solar thermal, heat pumps, micro-wind, micro-hydro and mCHP.

Unit 204 is the practical heart of the Level 2 qualification — the unit where you actually wire circuits under assessor observation. Under assessor supervision at our Nottingham training centre, you will install real wiring systems using thermoplastic single and multi-core cable, SWA, fire-resistant cable, cable tray, cable conduit (steel and PVC) and cable trunking.

You will select the right hand and power tools for each task and carry out the correct safety checks before use; select materials and dimensions from working drawings; mark out and fix accessories; terminate cables correctly; and bond mains services to the main earthing terminal — identifying cable sizes, terminating cables, connecting bonding clamps and testing continuity. You will use JIB safe isolation procedures throughout.

Once installed, you will inspect the dead installation to confirm it conforms to IET standards, then carry out the initial tests: continuity of the protective conductor, ring final circuit test, insulation resistance, polarity, and functionality of switches and devices — recording every test result as you would on a real job. This is where you develop the practical competence employers and the NVQ assessor will expect.

Unit 210 develops the working relationships and information-handling skills every electrician needs on site. You will learn the roles of the construction team — architect, project manager/clerk of works, structural engineer, surveyor, building services engineer, quantity surveyor, buyer, estimator, contracts manager and construction manager — and how they relate to sub-contractors, site supervisors and other trades including bricklayers, joiners, plasterers, tilers, heating and ventilation fitters, gas fitters and ground workers. You will also know the key roles of site visitors: building control inspectors, water inspectors, HSE inspectors and electrical services inspectors.

The unit then covers the paperwork and commercial side of site work — statutory legislation (data protection, equal opportunities, health and safety, employment), British Standards, codes of practice and manufacturer guidance; job specifications, plans, work programmes, delivery notes and time sheets; and the customer-facing documents electricians produce: quotations, estimates, invoices and handover information. You will also develop practical communication skills — oral and written methods including email and letters, accessible communication for learners with physical disabilities or language differences, conflict resolution between co-workers or customers, and the business impact of poor communication on an electrical contractor.

Carried forward from Level 2. Working safely on site, key regulations, protective equipment, and hazard procedures including asbestos. Per City & Guilds 2365-03 handbook v1.13: Unit 201 is one of the seven mandatory units for the Level 3 Diploma; learners who completed Unit 201 in Level 2 are exempt from re-assessment.

Unit 301 is the Level 3 introduction to micro-renewable energy and water-conservation technologies — 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 solar photovoltaic (PV), solar thermal, ground-source and air-source heat pumps, biomass, micro-wind, micro-hydro and micro-combined heat and power (mCHP), plus rainwater harvesting and greywater re-use.

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.

Unit 302 takes the science from Level 2 into the territory a working electrician actually needs: three-phase systems, complex AC circuits, and the machines and components found on commercial and industrial sites. You will understand electrical supply systems from generation through transmission and distribution, the relationship between single-phase and three-phase supplies, and the characteristics of star (wye) and delta connections.

The unit covers how different electrical properties — resistance, impedance, inductance, capacitance, frequency — affect real circuits, systems and equipment. You will learn the operation of DC machines and AC motors (induction, synchronous, single-phase and three-phase), power factor correction, and the electronic components used in motor control, lighting and heating systems.

Topics also include the principles of lighting and heating — lumen method calculations, luminaire selection, LED driver electronics, direct and indirect heating systems — giving you the theoretical grounding for the circuit design work you will meet in Unit 305. Assessed by written exam and a small practical exam.

Unit 303 is one of the most practical Level 3 units — fault diagnosis on live electrical installations. You will learn the specific health and safety requirements that apply when diagnosing faults: safe isolation to BS 7671, live working dispensation under EAWR, hazards specific to testing live circuits, and the PPE and test-instrument requirements for fault-finding work.

The unit covers the common fault types encountered on domestic, commercial and industrial installations — open circuits, short circuits, high-resistance joints, insulation breakdown, earth faults, overload faults, transient and intermittent faults — and the diagnostic procedures to isolate each one: logical fault-finding, test-instrument selection (multifunction testers, clamp meters, thermal imaging), circuit diagrams and manufacturer data.

You will also cover the importance of clear reporting and customer communication — what to tell the customer, what goes on the remedial certificate, and when to escalate. The unit is assessed by both a practical exam (under observation) and a written online exam, so you will spend significant time at our Nottingham centre practising real fault-finding before sitting the assessment.

Unit 304 is the inspection, testing and commissioning unit — the Level 3 companion to the City & Guilds 2391 and the knowledge base you will rely on for every job you sign off. You will understand the statutory requirements for safe isolation of electrical circuits, the steps in initial verification of a new installation, and the sequence of inspection before an installation is placed into service.

The unit covers the full set of pre-energisation dead tests (continuity of protective conductors, ring final continuity, insulation resistance, polarity, earth-electrode resistance where applicable) and energised tests (earth-fault loop impedance, prospective fault current, RCD/RCBO operation and auto-disconnection times, phase rotation on three-phase). You will learn how to complete Electrical Installation Certificates (EICs), minor works certificates and Electrical Installation Condition Reports (EICRs) using the C1/C2/C3/FI coding system, and the commissioning steps for new circuits, consumer units and distribution boards.

Assessment is by practical exam and written paper plus an online multiple-choice test — so the unit combines significant practical time at our Nottingham centre with structured knowledge assessment.

Unit 305 is the electrical design unit — where you move from installing circuits someone else specified to designing your own. You will learn how to prepare for the installation of wiring systems, select the right wiring system for each application, and follow the correct work practices and procedures from site survey through to handover.

The unit covers supply systems and consumer equipment: single-phase and three-phase supplies, consumer unit selection, switchgear, distribution boards and busbar systems. You will learn the full earthing and protection landscape — earthing arrangements (TT, TN-S, TN-C-S), main and supplementary bonding, automatic disconnection of supply (ADS), and the selection of overcurrent protective devices (fuses to BS 88 and BS 3036, circuit breakers to BS EN 60898, RCDs to BS EN 61008 and RCBOs to BS EN 61009).

The design work itself covers circuit design calculations — cable current-carrying capacity using the BS 7671 tables, correction factors (Ca, Cc, Cg, Ci), voltage drop, earth-loop impedance (Zs) and prospective fault current — so you can specify compliant final circuits, distribution circuits and the full installation for a real building. Assessed by practical exam, written paper and online exam.

Unit 308 closes the Level 3 Diploma with an overview of the qualified-electrician pathway and the career options that open up once you hold the 2365 Level 3. You will understand how to plan for a career in building services engineering: the role of the NVQ Level 3 (2357) in formalising on-site competence, the AM2 practical end-assessment, and the route to the JIB Gold Card and ECS registration that employers and site managers look for.

The unit also covers the wider industry picture — the different trade routes you can specialise in after qualification (inspection and testing, EV charging, solar PV and battery storage, commercial and industrial installation, maintenance, design), the Competent Person Schemes (NICEIC, NAPIT, ELECSA) and what registering with one of them enables, and the self-employment versus employed trade-off in earnings and responsibility. By the end of the unit you will know exactly where the 2365 Level 3 fits in the bigger qualification landscape and what the next steps look like.
