Amendment 4 (2026) to BS 7671:2018 IET Wiring Regulations.

I assume it’s now less than a year until the 4th Amendment is published, here on the IET website it says:

Amendment 4 is expected to be published in 2026, until that time electrical installers need to have a copy of Amendment 2 (2022) - the ‘brown book’ and Amendment 3 (2024) (free PDF bolt-on) to be up to date.

So, it is time to start planning ahead.

My first question is it a new book? There seems to be a lot of additional information and possibly changes as well.

My second question is, will there be an update qualification requiring a day on more in a training centre with an exam to be taken?

I have a couple of IET book markers somewhere with some information about this printed on them, but I’m not sure where they are at this moment.

There is a third question, which is when the 19th Edition is being published, which presumably will require new books and an exam, but I assume that won’t be published for at least two years?

  • Does it matter? Save that as I recall, the exams are for new editions rather than amendments.

    Point of contention (first time this came to light for "not having a recent amendment" of an Ed), is that if you had '16th Ed' prior to a certain date, before taking '17th Ed' you had to do a longer course.

    This has, of course, nothing to do with the contents of BS 7671, but views in industry as to which version of which qualification makes one "competent" [as   pointed out in an earlier post, even if the qualification in question is targetted at "how do I look things up in the standard?"]. Of course, this applies "universally" ... including those who are involved in developing the standard !

  • views in industry as to which version of which qualification makes one "competent"

    Driven, no doubt, by the registered competent persons' schemes.

    I qualified on 17th Edn. When 18th came along, as I recall, the "strong advice" was to do a 1 day course, which finished with the C&G exam. However, for less money, time, and effort, it was possible just to turn up for the exam

    That was Stroma for you. If registration is conditional on having the C&G qualification for the current exam, and only the schemes run the exams at the end of a course, it begins to look like a monopoly, or at least a duopoly.
