Electrician interview scorecard

Evaluate Electrician candidates across four weighted areas: hands-on competence, safety discipline, fault finding, and reliability and conduct. Hands-on competence leads at 35%, so check what they wire day to day: three-phase distribution boards, SWA terminations, containment runs, EV charge points, emergency lighting. Ask which qualification they hold (2391, 18th Edition, ECS card). Use the rubric to compare role-specific evidence consistently.

TL;DR
For hands-on competence, look for evidence the candidate names specific installs with cable sizes and board types, holds current 18th Edition plus inspection and testing qualification, references BS 7671 naturally. For safety discipline, look for evidence the candidate recites safe isolation sequence without prompting, refuses live working, describes stopping a job over an unsafe consumer unit or missing earthing. Apply the written 1–5 anchors to every answer, record the evidence behind each rating, and use the factor weights to reach a consistent overall assessment.

What to assess and how to score it

Review the evidence signals before interviewing. Then use the anchored descriptions—not instinct alone—to choose the score that best matches each answer.

01
Evaluation factor

Hands-on competence

35% weight

Check what they wire day to day: three-phase distribution boards, SWA terminations, containment runs, EV charge points, emergency lighting. Ask which qualification they hold (2391, 18th Edition, ECS card).

Evidence to listen for

  • Names the equipment, materials, and tolerances they work to
  • Can describe a job start to finish without hand-waving the hard parts
  • Holds the tickets, licences, or certifications the work requires, and they are current
  • Knows what they are not qualified to touch

Five-point scoring guide

1
Poor

Cannot describe the work concretely; lacks required tickets or licences.

2
Needs Improvement

Basic familiarity; needs supervision on routine tasks.

3
Satisfactory

Competent on standard work; slower or unsure on unfamiliar jobs.

4
Very Good

Skilled and independent across the normal range of the role.

5
Excellent

Names specific installs with cable sizes and board types, holds current 18th Edition plus inspection and testing qualification, references BS 7671 naturally.

02
Evaluation factor

Safety discipline

30% weight

Probe safe isolation step by step: proving unit, lock-off kit, GS38 test leads, permits. Ask about work near live parts and how they handle asbestos or unsafe existing wiring.

Evidence to listen for

  • Treats procedure as protection rather than paperwork
  • Can describe a time they stopped work and why
  • Knows the specific hazards of this trade and the controls for each
  • Reports near misses instead of hiding them

Five-point scoring guide

1
Poor

Casual about safety; describes shortcuts with pride.

2
Needs Improvement

Follows procedure when watched; cannot name the hazards that matter.

3
Satisfactory

Sound safety habits; less certain on unfamiliar hazards.

4
Very Good

Safety is instinctive; can describe stopping work over a real concern.

5
Excellent

Recites safe isolation sequence without prompting, refuses live working, describes stopping a job over an unsafe consumer unit or missing earthing.

03
Evaluation factor

Fault finding

20% weight

Test diagnosis of intermittent faults: nuisance RCD tripping, high Zs readings, borrowed neutrals. Ask which instruments they use (MFT, clamp meter, insulation resistance tester) and how they narrow it down.

Evidence to listen for

  • Has a method for narrowing a fault rather than swapping parts
  • Reads schematics, manuals, or error codes and acts on them
  • Knows when to escalate rather than guess
  • Can describe a fault that took real work to find

Five-point scoring guide

1
Poor

Parts-swapper; no diagnostic method.

2
Needs Improvement

Fixes symptoms; cannot explain how they found the cause.

3
Satisfactory

Solid on familiar faults; less structured on new ones.

4
Very Good

Clear systematic method with a real hard-fault story.

5
Excellent

Walks a real fault to root cause using measured values, explains split-load or circuit-splitting logic, quotes test results rather than guesswork.

04
Evaluation factor

Reliability and conduct

15% weight

Look for evidence of finished paperwork: EICs, minor works certificates, EICRs with correct C1 to C3 coding, plus punctuality on site and conduct in occupied homes.

Evidence to listen for

  • Turns up, on time, prepared
  • Handles shift work, callouts, or travel as the role requires
  • Documents work so the next person can pick it up
  • Deals with customers or site staff professionally

Five-point scoring guide

1
Poor

Unreliable attendance; unprofessional on site.

2
Needs Improvement

Inconsistent; documentation is an afterthought.

3
Satisfactory

Dependable; paperwork is adequate.

4
Very Good

Consistently reliable, documents well, professional with customers.

5
Excellent

Produces complete certification without chasing, arrives ready with own tools and calibrated instruments, leaves clean sites and cites repeat client work.
