18th Edition Wiring Regulations – FAQs

What will happen to the 2382-15?

The 2382-15 exam (yellow book) was available until 31/12/18 as a 2 hour, open book, online multiple choice exam.


When will the 2382-18 be introduced?

The ‘new’ 2382-18 qualification became available from 1/7/18 and also involves a 2 hour, open book (blue), 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 2382-15 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 were BS7671 neutral, meaning that any exam taken between July 2018 and January 2019 was in line with both the 17th Edition (yellow) and 18th Edition (blue) until 1/1/19.  From 1/1/19 only the 18th Edition (blue book) is permitted.  This also applies to the Guidance Note 3 book and On-Site Guide book.

The 2377 PAT Testing will not be changed for the time being and will remain aligned to the current IET Code of Practice for In-Service Inspection and Testing.
