1.1 About the City & Guilds 2365 Level 2 Qualification

About the City & Guilds 2365 Level 2 Qualification

The City & Guilds Level 2 Diploma in Electrical Installations (Buildings and Structures) (2365-02) is a college- and training-centre-based qualification for people who want to work as electricians in the building services engineering sector. It is regulated by Ofqual under accreditation number 600/5498/0 and is approved for learners aged 16 and over. City & Guilds sets no formal entry requirements, but centres must make sure each candidate has the potential and opportunity to achieve it.

The current qualification handbook is Version 1.12 (April 2026), which City & Guilds updated throughout for BS 7671 Amendment 4. Treat that handbook as your blueprint: the learning outcomes, assessment criteria and test specifications used in this guide come from it.

Structure: Five Mandatory Units, 49 Credits

To achieve the diploma you must gain 49 credits from five mandatory units. Total Qualification Time (TQT) is 490 hours, of which 454 are guided learning hours (GLH).

Unit 204 carries the most credits and guided hours because it is the hands-on workshop unit. The other four units are knowledge units tested on City & Guilds' online e-volve platform, which your centre books for you.

The Four Online Tests (Handbook Section 4.1)

City & Guilds publishes each grade boundary only as an approximate pass mark ("pass is approximately 60%", or approximately 50% for Unit 202). The handbook does not publish merit or distinction bands for these tests, so treat each one as pass/fail and aim comfortably above the boundary. Unit 203 is the only open-book test: Appendix 3 of the handbook lists the IET On-Site Guide as its normative reference.

Where the marks are: questions per learning outcome

The test specifications state how many questions come from each learning outcome (LO). Use them to plan your revision time.

What Each Unit Covers

Unit 201: Health and safety in building services engineering

Roles and responsibilities under health and safety and environmental legislation (HASAWA, the Electricity at Work Regulations, the Management Regulations, the Workplace Regulations, COSHH, Work at Height, PPE, Manual Handling, PUWER and the Control of Asbestos Regulations, plus the Environmental Protection Act, Hazardous Waste and WEEE Regulations and others); accident, first-aid and emergency procedures; RIDDOR; risk assessments, method statements and permits to work; PPE; safe use of access equipment, tools and materials; safe isolation; CLP hazard pictograms; fire extinguisher selection; and asbestos. The practical assignment (211) assesses practical skills such as safe isolation.

Unit 202: Principles of electrical science

Maths for electricians (fractions, percentages, algebra, indices, transposition, triangles, trigonometry and statistics), SI units and measuring instruments, mechanics (mass and weight, levers, gears and pulleys, work, energy, power and efficiency), electron theory, conductors and insulators, resistance and resistivity, series and parallel d.c. circuits, power, voltage drop, the chemical and thermal effects of current, magnetism and electromagnetism, a.c. generation and sine-wave values, and electronic components such as diodes, thyristors and triacs.

Unit 203: Electrical installations technology

Statutory and non-statutory regulations, technical information (specifications, drawing types, symbols and scale), circuit types and wiring systems for different environments, minimum current-carrying capacity ($I_b$, $I_n$, $I_z$, $I_t$ and rating factors), protective devices, specialised installation tools, conduit and trunking capacity, earthing systems (TT, TN-S, TN-C-S PME and PNB), automatic disconnection of supply and the earth fault loop path, generation, transmission and distribution, and micro-renewable energy technologies.

Unit 204: Installation of wiring systems and enclosures

The practical unit: hand and power tools and their safety checks; preparing the work area (hazards, PPE and access equipment); installing and terminating wiring systems and enclosures from drawings (thermoplastic, fire-resistant, data and armoured cables; steel and PVC conduit; trunking and tray); using the JIB safe isolation procedure; bonding services to the main earthing terminal; inspecting a dead installation; and dead testing (continuity of protective conductors, ring final circuit continuity, insulation resistance, polarity and functionality), then recording the results.

Unit 210: Understand how to communicate with others within building services engineering

The roles of the site management team, the trades and site visitors; statutory legislation and guidance information; workplace documents (job specifications, drawings, work programmes, delivery notes, time sheets and policies); customer information (quotations, estimates, invoices, statutory cancellation rights and handover information); company policies and limits of authority; and effective communication, including with people with disabilities or language differences and when resolving conflict.

Progression After the Level 2 Diploma

The handbook lists progression into employment (not as a fully qualified electrician) or onto further City & Guilds qualifications, including the Level 3 Diploma in Electrical Installations (Buildings and Structures), the Level 3 Diploma in Electrotechnology, and Level 3 awards in initial verification and in periodic inspection and testing. Most learners then complete workplace (NVQ) evidence and an industry end test such as the AM2 or AM2S, and hold a current BS 7671 wiring regulations qualification (City & Guilds 2382).

Confirm the exact route with your centre or employer, because apprenticeship standards and card schemes change more often than the 2365 handbook does.
