Practical guidance for the 2382-22 exam — format, pass mark, question types, revision tips, and common mistakes to avoid.
The City & Guilds 2382-22 Level 3 Award in Requirements for Electrical Installations is the formal qualification based on BS 7671:2018+A2:2022 — the 18th Edition of the IET Wiring Regulations including Amendment 2. It is the standard qualification that proves you understand and can apply the current UK wiring regulations.
The exam is a closed-hall, open-book assessment. You sit in an invigilated exam room with your copy of BS 7671 and answer 60 multiple-choice questions in 2 hours. The pass mark is 60% — meaning 36 correct answers out of 60. There is no negative marking, so you should always attempt every question.
Unlike many professional qualifications, this exam does not test your ability to memorise regulation numbers. It tests whether you can navigate BS 7671 efficiently, understand what the regulations require, and apply them to realistic scenarios. The candidates who pass comfortably are those who know their way around the book, not those who try to memorise everything.
The 2382-22 exam follows a consistent format. Understanding this structure will help you plan your time and approach on the day.
Questions are drawn from across the full breadth of BS 7671. However, certain areas feature more heavily than others. Based on the qualification specification and past exam analysis, the typical weighting is:
Time Management
With 60 questions in 120 minutes, you have exactly 2 minutes per question. In practice, some questions can be answered in under a minute (if you know the regulation or can find it quickly), which gives you extra time for more complex lookup questions. Aim to complete a first pass through all 60 questions, flagging any you are unsure about, then use remaining time to revisit flagged questions.
The exam includes several distinct question styles. Recognising the type of question will help you determine whether to look up the answer or apply your knowledge directly.
These questions ask you to find a specific regulation number and identify what it states. For example: "According to Regulation 411.3.4, additional protection by an RCD with a rated residual operating current not exceeding what value is required for socket outlets not exceeding 32 A?" The answer (30 mA) can be found directly by turning to the regulation. If your book is well-tabbed, these are quick wins.
These require you to find a value in the tables of BS 7671, particularly in Appendix 4 (current-carrying capacity and voltage drop). For example, you might be given a cable type, installation method, and ambient temperature, and asked to determine the current-carrying capacity. Practise navigating these tables before the exam — they can be confusing under pressure if you are not familiar with the layout.
These questions describe a practical situation and ask you to identify the correct regulation or requirement. For example: "A new kitchen installation in a domestic property includes a socket outlet rated at 13 A. What type of RCD protection is required?" These questions test your understanding of how regulations apply in real-world contexts.
A smaller number of questions test your knowledge of technical definitions from Part 2 of BS 7671. For example, the difference between "basic protection" and "fault protection", or the definition of "skilled person (electrically)" versus "instructed person (electrically)". Tab the definitions section of your book so you can check these quickly.
Part 7 questions test the additional requirements for specific environments. Bathroom zones (Section 701) are a perennial favourite — know the zone dimensions, IP rating requirements, and which equipment can be installed in each zone. Questions on Section 722 (electric vehicle charging) and Section 716 (prosumer installations) have become increasingly common since Amendment 2.
Success in the 2382-22 exam comes down to two things: understanding the structure of BS 7671 and being able to navigate it quickly. Here is a systematic preparation approach.
Buy or borrow a copy of BS 7671:2018+A2:2022. This must be the version that includes Amendment 2. Spend time reading through the contents page, the index, and each part heading. The exam rewards familiarity with the book's layout above all else.
Tab the key sections with coloured sticky tabs. A common system is:
While the exam is open book, certain regulations come up so frequently that you should know them without needing to look them up. This saves significant time. The regulations worth committing to memory include:
The most effective preparation is practising with exam-style questions under timed conditions. Your training provider should supply practice papers. When you get a question wrong, do not just read the correct answer — find the regulation in BS 7671 and read it in context. This reinforces your ability to navigate the book.
A good 2382-22 course will walk you through each part of BS 7671, highlight the key regulations, and give you practice navigating the book. The course instructor will also share insights about common exam questions and the areas where candidates typically lose marks.

Our course includes exam preparation, practice papers, and tips for navigating BS 7671 efficiently.
Knowing what to expect reduces anxiety and helps you focus on the questions rather than the process.
Arrive early. You will need to present photographic ID (passport or driving licence). The invigilator may check your copy of BS 7671 to ensure it does not contain loose inserts. You will be seated at a desk with your exam paper, answer sheet, a pencil, and your BS 7671 book. Electronic devices must be switched off and placed in your bag.
Read each question carefully. Many candidates lose marks by misreading the question — particularly questions that ask for the answer that is not correct or the minimum requirement. If you are unsure of an answer, make your best guess and mark the question for review. Never leave a question blank.
For lookup questions, go straight to the relevant section of BS 7671. If you cannot find the answer within a minute, try the index at the back of the book — it is comprehensive and can often get you to the right regulation faster than scanning through pages.
Results are typically available within a few weeks. Your training provider will advise on the expected timeline. If you pass, you will receive a City & Guilds certificate confirming your 2382-22 qualification. This is the document you will need to show to competent person schemes, employers, and building control.
Common Mistakes to Avoid
The most common reasons candidates fail the 2382-22 exam are: (1) poor time management — spending too long on difficult questions and running out of time; (2) not tabbing BS 7671 before the exam, making lookups slow; (3) misreading questions, especially those that include "not" or "except"; and (4) relying solely on memory rather than checking the book, even for regulations they think they know.
The 18th Edition certificate is a foundational qualification, but it is rarely sufficient on its own. It is one component of the professional competence portfolio that electricians need to work independently, join a competent person scheme, or obtain an ECS card.
If you are training to become an electrician through the diploma route, the 18th Edition is typically taken after completing the Level 2 and Level 3 diplomas (2365) and before the 2391 inspection and testing qualification. The knowledge of BS 7671 gained here forms the foundation for the 2391, which tests your ability to apply the regulations during practical inspection and testing.
If you are an established electrician updating from the 17th Edition or an earlier version of the 18th Edition (pre-Amendment 2), your priority is notifying your competent person scheme that you have updated. NICEIC, NAPIT, and ELECSA all maintain records of your qualification status and will expect to see evidence of your current 2382-22 certificate.
