An update to the IET's Wiring Regulations will be released early next year

Essential wiring regulations update to be launched in 2015

The IET will launch an update to its Wiring Regulations in January next year, the Institution has announced today.

The amended IET Wiring Regulations, which sets out the national standard for which all new and amended electrical installations are to comply, will feature a number of important changes and will be available from the IET from 5 January 2015.

This latest amendment, the third following Amendment  No.1 which was published back in 2011 and Amendment No.2 in 2013, will be  published as a new consolidated book. The amended regulations will include changes to the electrical condition report section, new requirements for mobile and transportable electrical units and changes for the installation of luminaires and light fittings – bringing them in line with the latest international and European standards.

The amended IET Wiring Regulations will also include the new Regulation 421.1.200. This regulation requires that within domestic (household) premises, consumer units and similar switchgear assemblies shall comply with BS EN 61439-3 and shall have their enclosure manufactured from non-combustible material, or enclosed in a cabinet or enclosure constructed of non-combustible material and complying with Regulation 132.12. This has been developed to safeguard against the risk of fire that can be produced from the overheating of connections in consumer units.  

Geoff Cronshaw, chief electrical engineer at the IET said: “The amended IET Wiring Regulations BS 7671:2008 incorporating Amendment No. 3:2015 will set the electrical standards for those professionals working in the electrical, construction and built environment industries. It is paramount that, as an organisation, the IET continues to ensure that electrical standards are up-to-date and relevant to the ever evolving requirements of the UK’s electrical industry.

“What’s more, it is essential that all electrical industry professionals familiarise themselves with the amended IET Wiring Regulations when they are published in January 2015, to ensure that the work they do is compliant and, most importantly, is carried out in a safe and appropriate manner.”

The IET will be making the amended Wiring Regulations available from 5 January 2015, both in print and via a digital subscription; more information and pre-orders are available now at
