18th Edition Mock Exam (BS 7671:2018+A4:2026)
Free 18th Edition mock exam covering BS 7671:2018 Amendment 4 (2026) — a timed practice exam with a worked answer on every question. 30 questions pulled from a 300-question bank: Chapter 41 protection against electric shock, RCD selection (Type AC restriction post-A4), AFDD recommendations under Reg 421.1.7, Section 722 EV charging, supplementary bonding, Section 701 special locations, inspection and testing. Retake it as often as you like — every attempt draws a fresh mock test from the bank, so it works as an exam simulator for the real open-book paper.

Common questions
Is the 18th Edition mock exam free?
Yes — 100% free, no sign-up needed. Questions are pulled at random from a substantial bank, with a worked explanation on every question after you submit.
Can I retake the mock exam?
Yes. Every attempt picks a different random selection and reshuffles the options, so each retake gives you genuinely new questions. No limit on retakes.
Does this count towards the real qualification?
No — this is independent practice material. To gain the actual qualification you need to sit the official assessment through an approved provider.
Is this mock exam like the real C&G 2382 18th Edition exam?
The real 2382 exam is 60 multiple-choice questions in 2 hours, open book (you can take a tabbed copy of BS 7671 and the On-Site Guide in), with a 60% pass mark and no negative marking. This mock uses the same multiple-choice format and regulation coverage in a shorter 30-question, 60-minute sitting — the per-question time pressure is deliberately similar, so treat it as timed practice for the paper.
Does this mock exam cover Amendment 4 (A4:2026)?
Yes. The question bank is written against BS 7671:2018+A4:2026, including the changes Amendment 4 made: AFDD recommendations under Regulation 421.1.7, the Type AC RCD restriction, and Section 722 EV charging requirements.
Can I practise specific 18th Edition topics instead of a full paper?
Yes — below the exam there are topic-by-topic practice pages drawn from the same bank, so you can drill just Chapter 41, special locations, or inspection and testing before sitting a full timed mock.
Should I use the book during this mock exam?
Practise the way you will sit the paper: the real 2382 is open book, and finding a regulation quickly matters as much as knowing it. Using a tabbed copy of BS 7671 under the timer is exactly the skill the exam tests — if a lookup takes you more than two minutes, tab that chapter.
