Minor Electrical Works Training Course for Maintenance Teams
A practical 1½-day electrical training course for maintenance teams, facilities personnel, estates staff and multi-skilled engineers who undertake defined minor electrical maintenance and like-for-like replacement work within their assessed level of competence.
Learn how to work safely on dead low-voltage circuits, carry out safe isolation, recognise electrical hazards, undertake appropriate basic inspection and testing, understand test results and correctly complete Minor Electrical Installation Works Certificates where appropriate.
Electrical Skills for Real Maintenance Teams
Move Beyond Electrical Awareness and Develop Practical Minor Works Skills
Maintenance teams are frequently asked to deal with relatively small electrical tasks as part of the normal operation of buildings, estates, factories, holiday parks, workshops and commercial facilities.
Replacing a damaged socket outlet, switch, luminaire, fused connection unit or other electrical accessory may appear straightforward, but even apparently simple electrical maintenance requires the person carrying out the work to understand the hazards involved, safely isolate the correct circuit and verify that the completed work is safe.
The SJB Electrical Training Minor Electrical Works Training Course has been developed specifically for suitably experienced maintenance personnel who need greater practical electrical capability without undertaking a full electrician training programme.
The 1½-day programme combines electrical safety, legislation, BS 7671:2018+A4:2026, safe isolation, practical maintenance exercises, inspection, basic electrical testing and completion of electrical documentation.
A key part of the course is also understanding when not to continue. Delegates learn to recognise the limits of minor electrical maintenance and when defects, unexpected results or the scope of work should be escalated to a more experienced electrical professional.
Practical Electrical Training
Learn the Process — Not Just the Theory
Minor electrical work is a practical activity, so this course contains a strong hands-on element.
Delegates work through realistic electrical maintenance scenarios, learning how to approach a job methodically from initial assessment and safe isolation through to replacement, inspection, testing and documentation.
- Assessing the task before work starts
- Identifying the correct electrical circuit
- Safe isolation and secure lock-off
- Using appropriate voltage indicators and proving devices
- Proving conductors dead before work starts
- Removing and replacing electrical accessories
- Checking conductor condition and terminations
- Basic inspection following completed work
- Using appropriate electrical test equipment
- Understanding whether results appear acceptable
- Completing appropriate electrical documentation
- Recognising when work must be escalated

Understanding the Scope
What Do We Mean by Minor Electrical Works?
The term minor electrical works should not be used to suggest that electrical work is automatically low risk or that any maintenance employee can undertake it.
For this course, the focus is on defined electrical maintenance tasks undertaken by personnel who have been appropriately trained, assessed and authorised by their employer for the work concerned.
Typical workplace examples may include appropriate replacement of existing electrical equipment such as:
Socket Outlets
Replacement of an existing accessory with an appropriate equivalent where the circuit and installation are suitable.
Switches
Safe removal and replacement of suitable existing switching accessories on an identified circuit.
Lighting Accessories
Defined replacement of appropriate luminaires and associated accessories within the delegate’s authorised scope.
Fused Connection Units
Understanding connection, protection, conductor identification and safe replacement principles.
Damaged Accessories
Recognising damage, deterioration, overheating or unsafe conditions before deciding whether work can safely continue.
Defined Maintenance Tasks
Other appropriate tasks may be included where they fall within company procedures and the individual’s assessed competence.
Electrical Safety & Compliance
Understand Why Safe Electrical Maintenance Is a Legal Responsibility
Delegates are introduced to the legal and technical framework that sits behind electrical maintenance and safe systems of work.
Electricity at Work Regulations 1989
Understand duties relating to electrical systems, maintenance, isolation, safe working and competence.
Health and Safety at Work etc. Act 1974
Understand the wider responsibility to manage workplace risks and protect employees and others affected by work activities.
BS 7671:2018+A4:2026
Understand how the current IET Wiring Regulations influence electrical alterations, replacement work, inspection, testing and certification.
Competence & Supervision
Understand why electrical competence depends on the particular task, knowledge, training, experience and appropriate supervision.
Work Dead — Work Safely
Safe Isolation Is at the Heart of the Course
The SJB Minor Electrical Works course is based around safe working on correctly isolated dead circuits.
Delegates learn why switching something off is not the same as proving that it is safe to work on and why electrical isolation must be planned, secured and verified.
Identify
Correctly identify the equipment, circuit and potential sources of electrical energy before isolation begins.
Isolate & Secure
Understand correct isolation, lock-off, warning arrangements and control of the isolation point.
Prove Dead
Understand appropriate voltage-detection equipment, proving devices and verification that the circuit is dead at the point of work.

Inspection & Basic Testing
Understand What You Are Testing — and Why
Electrical testing should never become a process of simply connecting a multifunction tester and copying numbers onto a certificate.
Delegates are introduced to the purpose behind appropriate tests and checks so that they can understand what the result is intended to demonstrate.
Protective Conductors
Understand why continuity of the protective conductor matters and its role in electrical safety.
Polarity
Understand why correct polarity needs to be confirmed following electrical work.
Insulation
Understand the purpose of insulation resistance testing and why inappropriate testing can damage connected equipment.
Loop Impedance
Introduce the relationship between fault-loop impedance, protective devices and automatic disconnection.
RCD Protection
Understand the purpose of residual current protection and the significance of appropriate verification.
Interpret Results
Develop the confidence to recognise when a result looks wrong and work should stop rather than simply recording the number.
Electrical Certification
Learn How to Complete a Minor Electrical Installation Works Certificate
A Minor Electrical Installation Works Certificate is more than paperwork completed after a job.
The person signing it is recording information about the work, the circuit, the existing installation, inspection, testing and the safety of the completed work.
Delegates work through the current certificate structure and learn how the information connects to the physical work they have undertaken.
Description of the Work
Clearly identify what was changed or replaced, where the work took place and the existing circuit affected.
Existing Installation
Understand why defects, earthing arrangements and the condition of the existing installation cannot simply be ignored.
Circuit Information
Identify the circuit, protective device, conductor information and relevant protective arrangements.
Test Results
Understand where appropriate inspection and test results are recorded and why they need to make sense.
The Declaration
Understand what the person signing the certificate is declaring about the work, inspection, testing and safety of the installation.
Records
Understand why certificates should be retained and made available for future maintenance, alterations and inspection.
Competence Includes Knowing When to Stop
Recognise When Minor Works Become More Than Minor
One of the most important learning outcomes is recognising when an apparently straightforward maintenance job has identified a problem outside the individual’s authorised scope or level of competence.
Unexpected Test Results
If measured values are unexpected, inconsistent or cannot be properly interpreted, work should be escalated rather than guessed.
Existing Defects
Damage, overheating, unsuitable protective devices, earthing problems or deteriorated wiring may require further investigation.
Scope Has Changed
If the task develops into circuit alteration, new circuit work, distribution equipment changes or other more complex work, additional competence may be required.
Unable to Isolate Safely
If the correct source cannot be positively identified, isolated, secured and proved dead, the work does not proceed.
Installation Condition
Existing installation conditions may make a simple replacement unsuitable without further assessment or remedial work.
Beyond Authorisation
Delegates learn that company authorisation and individual competence define what work they are permitted to undertake.
Clear Limits of Competence
This Course Develops Maintenance Skills — It Does Not Create an Electrician in 1½ Days
The programme has deliberately been designed around the work that appropriate maintenance personnel may realistically be expected to undertake within controlled workplace procedures.
It is not a substitute for an electrical apprenticeship or broader electrical installation qualification and does not automatically authorise a delegate to undertake every type of electrical work.
Following training, employers should consider the individual’s previous knowledge, experience, demonstrated practical ability, the work they are expected to undertake and the systems on which they will work before defining their authorised responsibilities.
Benefits for Employers
Develop Safer, More Capable In-House Maintenance Teams
Improve Safety
Give maintenance personnel a structured method for approaching electrical work rather than relying on informal workplace habits.
Reduce Unnecessary Call-Outs
Appropriate in-house capability can allow simple, defined maintenance tasks to be managed without automatically outsourcing every electrical accessory replacement.
