Weekday or Weekend City & Guilds Level 3 Award in Initial Verification 2391-50

City & Guilds Level 3 Award in Initial Verification 2391-50 Course at The Builder Training Centre is a qualification that has been re-introduced and replaces the City & Guilds 2394 qualification.

City & Guild’s 2391-50 Course at The Builder Training Centre is designed for anyone who is required to conduct Initial Verification of electrical Installations. You will need to have previous experience and fundamental knowledge of inspecting and testing of single and ideally 3 phase electrical installations. You will need to have obtained previous electrical qualifications, able to work with minimal supervision, work safely, able to identify faults and ensure all your work meets the required standards. This course will enable you to update your knowledge of techniques and legislation and gain the relevant qualification to reflect your abilities.

This qualification is particularly relevant to those wishing to verify new installations and perhaps not required to carry out periodic inspection and testing, such as Domestic Installers.

This qualification is the equivalent of the EAL 4337 qualification.   It is JIB recognised.


Ideally candidates will have the City & Guilds 2392-10 qualification prior to attending this course.

This qualification is similar to the City & Guilds 2392-10 qualification, except that the 2391-50 is a Level 3 qualification and includes 3 phase.
