The City & Guilds 2391-52 Level 3 Award combines initial verification and periodic inspection and testing of electrical installations, covering both new work (Electrical Installation Certificates) and existing installations (Electrical Installation Condition Reports). It is assessed by two components that must both be passed: the 2391-052 online multiple-choice test (60 questions, 120 minutes, open book, pass mark approximately 75%) and the 2391-502 practical assignment, which includes a short-answer written paper. Testing dominates the paper — learning outcome 4 carries 33 of the 60 questions. Candidates must master the sequence of tests, continuity, insulation resistance, polarity, earth fault loop impedance (Ze/Zs and the 0.8 rule), prospective fault current, RCD verification at IΔn, phase sequence, functional testing, voltage drop and EICR observation coding (C1, C2, C3, FI). This free prep includes 100 research-based practice questions with explanations and an AI tutor.

Our practice resources: topics covered
We aim to reflect publicly available exam outlines and topic information in our study resources. Coverage, format, and difficulty may differ from the actual exam, and we cannot guarantee that every detail is accurate or current. Confirm exam requirements, fees, and policies with the official exam sponsor.
LO1 Requirements for inspection and testing
Purpose of initial verification and periodic inspection, reasons for inspection and testing, comparing the two processes, the documents issued (EIC, MEIWC, EICR and their schedules), statutory and non-statutory documents, the information needed to agree extent, limitations and sampling, signatory responsibilities, and recording and retention (13 of the 60 questions)
LO2 Safety management procedures
Health and safety requirements when inspecting and testing, the relevant requirements of the Electricity at Work Regulations 1989, the safe isolation procedure to HSE guidance, why safe isolation is carried out and the implications of omitting it (3 of the 60 questions)
LO3 Requirements for the inspection of electrical installations
Items to be inspected against the BS 7671 schedule of inspections, how each item is verified or classified, the human senses used in inspection, dealing with an item found unsatisfactory at initial verification versus periodic inspection, and the IP classification system (11 of the 60 questions)
LO4 Requirements for testing electrical installations
Instrument maintenance, calibration and GS38 leads; why a test sequence exists for initial verification but not for periodic inspection; the purpose, method, influencing factors and interpretation of every test — continuity of protective conductors and ring final circuits, insulation resistance including electrically separated circuits, polarity, earth electrode, earth fault loop impedance, RCD tests, prospective fault current, phase sequence, functional testing and voltage drop (33 of the 60 questions)
LO5 Perform inspection and testing of electrical installations
Establishing a safe system of work, carrying out safe isolation, inspecting and testing to BS 7671 and IET Guidance Note 3, verifying results for compliance or classification, and completing the certification — assessed entirely by the 2391-502 practical assignment, so it carries none of the 60 multiple-choice questions

Frequently Asked Questions
How many questions are on the City & Guilds 2391-52 multiple-choice exam and how long is it?
The 2391-052 online e-volve test has 60 questions and lasts 120 minutes. It is open book and invigilated, and the pass mark is set at approximately 75%. The 60 questions are split across the official learning outcomes: 13 on requirements, 3 on safety management, 11 on inspection and 33 on testing.
What score do I need to pass the 2391-52 exam?
The City & Guilds qualification handbook states the pass mark for the 2391-052 multiple-choice test is set at approximately 75%, and that it may be adjusted to ensure consistency across cohorts. The 2391-502 practical assignment is graded pass/fail and is assessed separately; both must be passed to achieve the award.
How many assessments does the 2391-52 have?
Two. The qualification handbook requires candidates to successfully complete one practical assignment (2391-502) and one online multiple-choice test (2391-052). The short-answer written paper is a task within the practical assignment, not a separate third exam.
What is the difference between 2391-50, 2391-51 and 2391-52?
The 2391-50 covers initial verification of new work, the 2391-51 covers periodic inspection and testing of existing installations, and the 2391-52 combines both into a single Level 3 Award covering Electrical Installation Certificates and Electrical Installation Condition Reports.
Is the 2391-52 exam open book?
Yes. The qualification handbook records the assessment conditions for the 2391-052 test as open book and invigilated, so you may refer to BS 7671:2018+A4:2026 and normally IET Guidance Note 3 and the On-Site Guide. Confirm the permitted titles with your centre, because City & Guilds does not publish a national list.
What are the EICR codes C1, C2, C3 and FI?
C1 means danger present with immediate action required, C2 means potentially dangerous with urgent action required, C3 means improvement recommended, and FI means further investigation is advised. Under BS 7671:2018+A4:2026 only C1 or C2 make a report unsatisfactory; C3 and FI have been decoupled from the outcome and do not by themselves make it unsatisfactory.
Do I need the 18th Edition before taking the 2391-52?
City & Guilds expects candidates to have achieved a Level 3 Electrotechnical qualification or similar, and states the award must not be taken by anyone new to the industry. Most training providers additionally require a current 18th Edition award — now the 2382-26, updated for Amendment 4:2026 — because the exam is open book against BS 7671.
Is this free 2391-52 practice as good as paid prep?
Our 100 practice questions cover the full 2391-52 theory syllabus with a teaching explanation for every answer, real BS 7671:2018+A4:2026 and Guidance Note 3 values, plus free daily AI tutor interactions. All content is free forever and updated for 2026.
