18th Edition Wiring Regulations – FAQs

What will happen to the 2382-18?

The existing 2382-18 qualification (including Amendment 1) will continue to be available until 28/9/22 as a 2 hour, open book (blue), online multiple choice exam.

When will the 2382-22 be introduced?

The ‘new’ 2382-22 qualification (including Amendment 2) is now available (as of 28/3/22) and also involves a 2 hour, open book (brown), online multiple choice exam.

Will there be a shorter update 2382 exam?

An agreement between all awarding organisations and the JIB concluded that all those sitting an exam on BS7671 should be able to understand all parts, not just the changes.  However, centres may choose to offer update courses to those with the 2382-18 on the changes only but the examination will be the same.

How will this effect other short courses such as the 2393, 2392, 2391 (or equivalent 2625) or 2919?

All questions will be BS7671 neutral, meaning that any exam taken between 28th March 2022 and 28th September 2022 will be in line with both the 18th Edition (blue book) and 18th Edition (brown book) until 28th September 2022.  From 28th September 2022 only the 18th Edition (brown book) is permitted.  This also applies to the Guidance Note 3 book and On-Site Guide book.

The 2377 PAT Testing and 2919 Electric Vehicle Charging will not be changed for the time being.
