Question 1

Does this 2391 course cover both initial verification and periodic inspection?

Accepted Answer

Yes. The combined 2391-52 course covers initial verification for new electrical installations and periodic inspection for existing installations. That means the same classroom route prepares you for EICs, EICRs, Minor Works Certificates, dead testing, live testing and BS 7671 inspection documentation.

Question 2

Can I use 2391-52 for EICR work and landlord electrical safety certificates?

Accepted Answer

City & Guilds 2391-52 is a recognised way to evidence inspection and testing competence for EICR work. Landlord electrical safety reports must be completed by a competent person, so you still need suitable experience, insurance and any employer or scheme requirements. The course covers periodic inspection, condition codes, BS 7671 inspection records and EICR documentation.

Question 3

How is the 2391-52 assessed?

Accepted Answer

The 2391-52 course includes a written theory paper, an Initial Verification practical assessment and a Periodic Inspection practical assessment. The classroom days prepare you for the theory stage, then you complete a full practical assessment day in centre for the hands-on inspection and testing element. We run mock practicals during the course so you are familiar with the test rig before the real assessment.

Question 4

Is this the main 2391 inspection and testing course?

Accepted Answer

Yes. This is the City & Guilds 2391-52 inspection and testing course, the combined route that covers both 2391-50 Initial Verification and 2391-51 Periodic Inspection. It is designed for electricians who want one classroom course for EICs, EICRs, Minor Works Certificates and BS 7671 inspection and testing competence.

Question 5

What is the difference between 2391-50, 2391-51, and 2391-52?

Accepted Answer

2391-50 (Initial Verification) covers testing new installations and issuing Electrical Installation Certificates (EICs). 2391-51 (Periodic Inspection) covers inspecting existing installations and issuing EICRs — commonly called the 'electrical safety certificate' that landlords need. 2391-52 (Combined) merges both into a single 5-day qualification — it is the most popular and recommended route because it qualifies you for both new-build and existing-installation work.

Question 6

Do I need 18th Edition first?

Accepted Answer

Yes. After booking, LTS will request a copy of your 18th Edition certificate (2382-18, 2382-22 or 2382-26). If you hold 2382-18 or 2382-22, you must also confirm that your BS 7671 knowledge is current. The evidence and initial suitability review must be approved before awarding-body or exam registration. We run regular 18th Edition courses if you do not hold an accepted certificate.

Question 7

What are condition codes C1, C2, C3 and FI?

Accepted Answer

On an EICR you classify each observation: C1 (Danger present — immediate action required), C2 (Potentially dangerous — urgent remedial action), C3 (Improvement recommended — not dangerous but recommended upgrade), and FI (Further investigation required). C1 and C2 observations make the EICR an 'unsatisfactory' result. Correct coding is the single most-disputed part of inspection work and a major focus of the course.

Question 8

How does this compare to the online 2391-52?

Accepted Answer

The classroom 2391-52 (this course) includes hands-on practical assessments on live test rigs — required for the full qualification leading to certification. The online 2391-52 is a self-paced study aid (knowledge only) for revision or to bridge to a separate practical centre. If you need to actually inspect, test, and certify installations professionally, the classroom 2391-52 is the qualification employers and competent-person schemes recognise.

Question 9

Is 2391 required for NICEIC or NAPIT scheme membership?

Accepted Answer

NICEIC, NAPIT, ELECSA, and STROMA approved contractor / certified installer schemes require demonstrable inspection & testing competence — 2391-52 is the standard route to evidence this on your scheme application. Some schemes accept equivalent qualifications (e.g. 2394/2395 legacy or in-house competency portfolios), but a current 2391 family qualification is the path of least friction.

Question 10

How much can I earn doing inspection and testing work?

Accepted Answer

Inspection & testing is one of the highest-earning electrical specialisms. As a self-employed inspector, EICRs typically charge £150–£300 for a domestic 3-bed property (around 2 hours work). Employed inspectors with a 2391 typically earn £35,000–£48,000 plus van and tools. The ESPRS landlord-EICR market and EV-charger commissioning have grown 2391-qualified workloads significantly since 2020.

Question 11

Are there practical sessions and how many learners per class?

Accepted Answer

Yes — three of the five days are heavily practical. We use real test rigs (dead and live) and full BS 7671 documentation packs. Maximum 16 learners per class with two qualified tutors so you get genuine hands-on time with multimeters, MFTs, and earth-loop testers.

Question 12

Can I take 2391-52 if I have not done 2391-50 or 2391-51 separately?

Accepted Answer

Yes — 2391-52 is the combined qualification, so you take it as a standalone course. You don't need 2391-50 or 2391-51 first; in fact most learners go straight to 2391-52 because it costs less than the two standalone qualifications combined.
