BS7671 or Wiring Regulations?

UKPN
There is a guy on here asking "what is the point of the wiring regulations?" He hasnt explained his question, so I would like to expand a little.

If you pass the City and Guilds exam, you are awarded a certificate titled "BS7671 Requirements for Electrical Installations" The term "Wiring Regulations" is not on the sheet.

However, I note that most job requirements ask for 2391/2396/18th Wiring Regulations. Virtually no one talks in the context of " BS7671"

I am wondering if members can give me an idea how the two terms are related, who makes the decisions on "regulations" and who is accountable for those decisions. I have noted errors/confusion on various posts these last few days caused by ambiguity in those regulations and it seems the person who should be protected by these regulations (the customer) is the last to be considered.

Ever the cynic, is the term "wiring regulations" retained  for sentimental reasons or just to sell the book?

Thanks in advance.

    yet that very standard actually contains a requirement that implies that cabling installed to an earlier version is OK if there's a label stating two colours are used.

    Not quite in my mind - you couldn't install red & black today, claiming it complied with say BS 7671:1992(*) and then say the installation complies with BS 7671:2018 - the "is OK" bit is only referring to exiting installations (which as only new work has to comply with current regulations) isn't covered by updated versions of the regs - I think it's overstepping the mark to say that red/black complies with BS 7671:2018.


    That was only one example anyway, there are tons of differences between BS 7671:2018 and earlier versions that wouldn't comply with BS 7671:2018 yet wouldn't result in an unsatisfactory EICR when conducted to BS 7671:2018 - not just colour codes, but RCDs for internal sockets or concealed cables, or lack of SPDs.


    * And before anyone says that you can't install to an earlier version today, 'cos the regs themselves say that the later version should apply after a certain date, consider that the law now demands compliance with earlier version(s). It's all just a complete mess.
