Commercial Electrical Maintenance Checklist

Before you start

This checklist is intended as a practical management tool only. It does not replace formal electrical inspection, testing, certification or remedial work by a qualified electrical contractor.

If you identify exposed wiring, signs of overheating, burning smells, repeated tripping, damaged accessories or any other safety concern, arrange for the issue to be reviewed by a competent person as soon as possible.

Commercial electrical maintenance checklist

Use the sections below to review visible maintenance issues across your premises. The checklist should be adapted to your building, environment and how the space is used.

1. Distribution boards and circuits

Distribution boards should be accessible, secure, clearly labelled and free from visible signs of damage or overheating.

Check whether:

• Distribution boards are accessible.
• Circuit labels are clear and up to date.
• There are no stored items blocking access.
• Covers and components appear undamaged.
• There are no signs of overheating, scorch marks or discolouration.
• Circuits are not tripping repeatedly
• There is no evidence of unauthorised alterations.
• Recent electrical changes or works have been recorded.

Action: If distribution boards are poorly labelled, repeatedly tripping or showing signs of damage, arrange a professional review.

2. Internal and external lighting

Lighting should be reliable, suitable for the space and appropriate for the work being carried out.

Check whether:

• Internal lighting is working correctly.
• There are no failed lamps or fittings.
• Lights are not flickering.
• There are no dark spots or poor visibility issues.
• Fittings and covers are not damaged.
• Glare is not affecting working areas.
• External lighting is working around entrances, yards, car parks and loading areas.
• Lighting still suits the current layout and use of the space.

Action: If lighting is unreliable, inefficient or no longer suitable for the premises, it may need repair, replacement or a wider lighting review.

3. Emergency lighting

Emergency lighting should remain suitable for the current layout, use and escape routes within the building.

Check whether:

• Emergency lighting is present where required.
• Test records are available.
• Fittings appear undamaged.
• Escape routes have not changed without review.
• Layout changes have been considered.
• Previous emergency lighting defects have been actioned.
• Contractor records are available

Action: If test records are missing, fittings are damaged or the building layout has changed, speak to a qualified contractor about reviewing the emergency lighting provision.

4. Sockets, switches and accessories

Sockets, switches, isolators and accessories should be checked visually for damage, wear or signs of overheating.

Check whether:

• Sockets are secure and undamaged.
• Switches and isolators are in good condition.
• There are no scorch marks or discolouration.
• Accessories are not warm to the touch.
• There are no buzzing sounds.
• There is no exposed wiring.
• Faceplates are not cracked or loose.
• Extension leads or adaptors are not overloaded.

Action: Damaged, warm, loose or discoloured accessories should be reviewed by a competent person.

5. Visible cabling and containment

Visible cabling, trunking, conduit and containment should be protected, secure and free from obvious damage.

Check whether:

• Trunking or conduit is not loose or damaged.
• No exposed conductors are visible.
• Cables are protected from impact or damage.
• Cables are not exposed to moisture or heat.
• There are no trailing cables across walkways.
• Temporary wiring has not become permanent.
• Cable management is suitable for the area.
• Cables around workstations, machinery or operational areas are safely managed.

Action: Any damaged, exposed or poorly managed cabling should be reviewed by a qualified contractor.

6. Electrical records and certificates

Clear records help show what has been checked, what defects have been found and what actions have been completed.

Check whether you have records for:

• Electrical inspections.
• EICR reports, where applicable.
• Emergency lighting tests.
• Remedial works.
• Contractor visits.
• Fault reports.
• Changes to circuits or equipment.
• Outstanding maintenance recommendations.

Action: If records are missing, unclear or out of date, create a central log and speak to your contractor about what needs reviewing.

7. Defects and remedial actions

A checklist is only useful if issues are recorded and followed up.

For each defect, record:

• Location.
• Description of the issue.
• Date identified.
• Priority level.
• Action required.
• Person or contractor responsible.
• Target completion date.
• Completion date.
• Notes once resolved.

Action: Prioritise anything that could affect safety, business continuity or compliance records. Urgent issues should be escalated straight away.

What to do after completing the checklist

Once you have reviewed the premises, group your findings into three categories:

Urgent issues

These may include exposed wiring, burning smells, signs of overheating, repeated tripping, damaged distribution boards or unsafe accessories. These should be escalated quickly and reviewed by a competent person.

Planned remedial work

These may include damaged fittings, poor labelling, missing records, lighting issues or minor defects that need scheduling. These should be logged and given a target completion date.

Maintenance planning

These may include recurring issues, ageing systems, incomplete records or areas where the current electrical setup no longer suits how the building is used. These should be discussed as part of a wider electrical maintenance plan.
