ECA
ECA welcomes the announcement that the IET and the BSI are finalising Amendment 4 to BS 7671:2018, which will be known as the ‘orange book’.
A dedicated Amendment 4 webpage will be published in April, which will include guidance from ECA plus other support materials.
Mike Smith, Director of Technical and Safety, Health & Environment at ECA, said:
“The latest update to the UK’s national electrical safety regulations brings several important changes designed to improve safety, reliability and clarity for everyone who uses or manages electrical systems.
“These changes reflect the industry’s commitment to continual improvement and keeping pace with new technologies.”
Darren Crannis, Technical Manager at ECA, added:
“New guidance and updated Standards improve electrical safety across multiple areas: battery storage systems must meet strict installation requirements; IT and communications equipment now benefit from better protection and reliability; clear advice is provided for safely using Power over Ethernet (PoE); and medical settings have enhanced rules, including recording of important safety tests, to ensure the highest levels of protection.
“The ECA technical team are looking forward to helping Members understand the importance and impact of the changes and will be actively engaging with Members.”

EAL
EAL plans to launch a replacement Level 3 Award in the Requirements for Electrical Installations BS 7671:2018 qualification to Amendment 4 in April 2026. The current qualification will close for registration on 31 July 2026 and close for certifications on 31 December 2026. The onscreen exam will be available until 15 October 2026.
EAL will shortly be communicating further on how this update affects its qualifications.
Kevin Sparrow, Senior Industry Manager for Building Services Engineering (BSE) at EAL, commented:
“Amendment 4 is an important step, particularly in embracing new technology. Contractors are encouraged to undertake CPD to stay up to date to support continued competence in their role”.
SELECT
SELECT has welcomed the latest amendment to the IET Wiring Regulations – and encouraged Members to familiarise themselves with the updates to ensure the ongoing safety of contractors and customers.
Bob Cairney, Director of Technical Services, said:
“The association welcomes this latest amendment which is an essential update to continue to provide safe electrical installations across the UK.
“SELECT has participated with the IET and other industry bodies in the development of BS 7671 for many years through our contributions to the National Wiring Regulations JPEL/64 committee and we recognise the IET as the authority for electrical installations in the UK.
“JPEL/64 carefully considers all necessary updates to the regulations to ensure they continue to meet the needs of the industry and Amendment 4 continues the thread of embracing new technologies. The inclusion of a new section on stationary secondary batteries is an exciting step into the future of renewable sources of energy and their integration into our lives.”
Robert McGoogan, SELECT’S Director of Technical Services Designate, added:
“BS 7671 underpins safe, modern electrical infrastructure and is essential for delivering the electrification needed to meet net zero ambitions.
”Amendment 4 is an essential update to these regulations and will form the UK national standard for all-new low voltage electrical installations, additions and alterations to existing installations and periodic inspection and testing of existing installations.
“As the electrification of society continues, it is therefore essential for contractors to keep abreast of the latest updates and we would encourage all Members to familiarise themselves with Amendment 4 and its implications when it becomes available in April.”
SELECT will be discussing Amendment 4 and its implications for contractors at its upcoming Toolbox Talks, sponsored by Aico, which will visit 13 venues across Scotland in May, June and July. The association is also reviewing its wide range of training courses to ensure they are updated in line with BS 7671:2018 +A4:2026.
