The City & Guilds 2377-77 Certificate, formally titled the **Level 3 Award in the In-service Inspection and Testing of Electrical Equipment**, represents the gold standard for professionals engaged in the maintenance and safety verification of electrical appliances. Often still referred to by its traditional name, PAT Testing (Portable Appliance Testing), this contemporary qualification has evolved significantly to reflect the latest industry practices and legislative requirements .
An Evolving Qualification
The 2377-77 is the successor to the previous 2377-22 and 2377-32 qualifications and is aligned with the 5th Edition of the IET Code of Practice for In-service Inspection and Testing of Electrical Equipment . A key distinction of this updated course is its shift in focus from merely “portable” appliances to a broader scope encompassing all electrical equipment. Furthermore, it emphasises a risk-based approach to inspection, teaching candidates how to structure, implement, and document an electrical risk assessment rather than adhering to a rigid, one-size-fits-all testing schedule .

Who Should Undertake This Certification?
This certification is designed for individuals who possess a prior understanding of electrical systems. While City & Guilds does not mandate strict entry requirements, training centres strongly recommend that candidates are “electrically skilled.” This typically includes practicing electricians, those with an NVQ Level 3 in a related discipline, or holders of ECS or JIB electrician grade cards . Familiarity with the 18th Edition Wiring Regulations (BS7671) is also highly advantageous .
