18th Edition & 2391
Mock Exam Practice

🟠 18th Edition Amendment 4 (Orange Book) — 2382-26

The 2382-26 is the current 18th Edition exam, covering BS 7671:2018+A4:2026 — commonly known as the Orange Book. This latest amendment introduced significant changes that many older mock exams still don't cover:

• Chapter 57 — Battery Energy Storage Systems (new)
• Section 716 — Power over Ethernet (PoE) installations
• Section 545 — ICT earthing arrangements
• Section 722 — Updated EV charging point requirements
• Section 710 — Revised medical location requirements
• Updated energy efficiency provisions

Our 18th Edition mock exam bank is fully updated for Amendment 4. Practising on outdated 2382-22 (Brown Book) or 2382-18 (Blue Book) questions is a waste of time — you need the current Orange Book content.

🔬 2391 Inspection & Testing Explained

The City & Guilds 2391 series covers Initial Verification and Periodic Inspection & Testing of electrical installations. There are three variations, and choosing the right one matters:

• 2391-50 — Initial Verification only (testing new installations before energising)
• 2391-51 — Periodic Inspection only (EICR reports on existing installations)
• 2391-52 — Full/Combined qualification covering both Initial and Periodic (most electricians choose this)

All 2391 exams are open-book and you can bring both BS 7671 and IET Guidance Note 3. Roughly 50% of questions test practical applied judgement (interpreting test results, classification codes) rather than pure regulation lookup — our question bank reflects this split.

🎓 2365 Level 2 & Level 3 Diploma

The 2365 Diploma is the main academic route into the electrical trade, taken by apprentices at UK colleges. It has multiple units at Level 2 (foundational) and Level 3 (advanced), each with its own exam. We have full question banks for all major units:

Level 2 (2365):

• Unit 201 — H&S in Building Services Engineering
• Unit 202 — Principles of Electrical Science (closed-book, calculation-heavy)
• Unit 203 — Electrical Installations Technology
• Unit 210 — Communicate within Building Services Engineering

Level 3 (2365):

• Unit 301 — Environmental Technology Systems
• Unit 303 — Fault Diagnosis and Rectification
• Unit 304 — Inspection, Testing and Commissioning
• Unit 305 — Electrical Systems Design (open-book with BS 7671 & On-Site Guide)

Each unit's mock questions match the actual exam style — closed-book units test calculation and theory recall; open-book units test lookup speed and applied design judgement.
