This qualification is intended for learners who have previously gained qualifications in Initial Verification, perhaps through a recognised apprenticeship, and  wish to expand their skills to include reporting on the condition of existing electrical installations.


It allows candidates to progress to the Level 4 Award in Design and Verification of Electrical Installations (2396).


Candidates must have basic knowledge and understanding of electrical science and principles, and experience of electrical installation work, either within the electrical contracting industry or an allied trade.


A relevant qualification, such as City & Guilds 2360, 2330, 2357 or a level 3 2365 would be sufficient evidence of this. Candidates should also preferably hold a current 18th Edition qualification.

Candidates would normally hold the City & Guilds 2391-50, or the 2394 or equivalent.

Candidates must be aged 18+ .
