New, rewired and similar installations

This section incorporates questions relating to:

  • New or rewired domestic and similar installations
  • Alterations and additions in domestic and similar premises

You may notice that some numbers are missing from the Q&A. This is deliberate. The regulations are constantly updated and as questions become out of date, we remove them but do not renumber, as we are aware that visitors to the site will note specific numbers for future reference.

If you have any queries, please contact with "Wiring Regulations" as the subject line of your message.
