An updated 4th edition of this document was published in 2008. The standards set out in these rules should be applied for all new installations under construction and all extensions. The testing requirements for installations are also set out and should be applied when carrying out inspection and testing in accordance with the 2007 General Application Regulations.

Among the areas updated in the new wiring Regulations are sections on agriculture, temporary structures (such as marquees and fairgrounds) bathrooms and several others. In addition, the regulations set out a revised structure for certification and testing of installations, which should be adhered to. If you are commissioning an electrical works in your premises, then you should check and specify that the installation is being carried out in accordance with the up to date Wiring Regulations.
