New amendment to BS 7671 (IET Wiring Regulations)

05 September 2019

The amendment - which will soon be out for consultation - follows advances in technology, enabling a more practical solution for electric vehicle charging installations 

The IET has announced a new amendment to BS 7671:2018 (IET Wiring Regulations 18th Edition).  The national Wiring Regulations committee, JPEL/64, today agreed the publication of Amendment 1, which will (after a round of consultation) consist of a stand-alone update to Section 722: Electric Vehicle Charging Installations.

The amendment, which is due to publish in early 2020, will be free to view on the IET website, and only form part of a consolidated new Regulations following the next major amendment to BS 7671, expected in 2022.

The amendment follows advances in technology that were not available when BS 7671:2018 published, enabling a more practical solution for the installation of charging points.  Functionality built directly into charging equipment uses existing technology, but employed in a new way, allowing charging points to be deployed more widely than ever before.

The updated Section 722 should make installing charging points quicker and easier, and will reduce the cost of installations for both installers and consumers.

The UK government is investing £400 million to accelerate the roll-out of charging infrastructure to help meet its target of at least 50% of new car sales to be ultra-low emission by 2030*. 

“This update to the IET Wiring Regulations puts the electrical industry at the forefront of driving technological innovation to ensure the installation of practical, safe charging points that are accessible to all.

IET says that, “Producing Amendment 1 to BS 7671:2018 as a stand-alone, free-to-view document, this updated Section 722 will reach industry much quicker than a full, consolidated amendment would allow, enabling installers to take advantage of BS 7671:2018+A1:2020 as soon as possible.”

Proposed timeline for the latest changes:

  • October 2019: The Draft for Public Comment for Amendment 1 will be available for 60 days to allow industry to respond to the proposed changes (see theiet.org/updates for details)
  • January 2020: Amendment 1 will publish as a free-to-view document on the IET website and come immediately into effect, eschewing the usual 6-month adjustment period to ensure industry can immediately take advantage of the changes
  • February 2020: The IET will publish the 4th Edition of the Code of Practice for Electric Vehicle Charging Equipment Installation, incorporating new guidance based on Amendment 1 to BS 7671:2018
