What Should a Commercial Electrical Safety Checklist Include?
Last Updated: 28 October 2026
Quick Summary
A commercial electrical safety compliance checklist should cover fixed wiring and distribution boards, earthing, bonding and RCD protection, portable appliance testing, and the records that prove each check took place. It should also capture EICR defect codes and recommended next inspection dates, so you can show your systems are maintained to prevent danger.
Distribution boards should be labelled clearly with every circuit identified and circuit schedules matching what is installed.
RCDs must trip within their rated time when tested with a proper instrument, with dates and readings recorded.
Defect codes are C1 for danger present, C2 potentially dangerous, C3 improvement recommended and FI further investigation.
PAT frequency should be risk-based, from annual for power tools to several years for low-risk office equipment.
An inspection report template should capture six fields, including test readings, defect code and remedial action.

What a Commercial Electrical Safety Compliance Checklist Must Cover
A commercial electrical safety compliance checklist is a documented set of inspections, tests and records that shows a business has taken reasonable steps to keep its electrical systems safe. It covers fixed wiring, distribution boards, earthing, RCD protection, portable appliances and the paper trail that proves each check happened.
Below, we break down what belongs on a commercial electrical safety compliance checklist, section by section.
Fixed wiring and distribution boards
Fixed wiring is the cabling inside your walls, floors and ceilings, plus the distribution boards that feed every circuit. It's the part of the system nobody looks at until something fails.
Your checklist should confirm:
Distribution boards are labelled clearly, with every circuit identified
No signs of overheating, scorch marks or discoloured accessories
Covers and enclosures are intact, with no gaps or missing screws
Spare ways are blanked off properly
Cable insulation shows no cracking, damage or rodent activity
Circuit schedules match what's actually installed
Earthing, bonding and RCD protection
Earthing and bonding give fault current somewhere safe to go. Residual current devices (RCDs) cut the power when current leaks to earth. Both are life-safety systems, and both belong on every commercial electrical safety compliance checklist.
Check that:
Main earthing and bonding conductors are present, secure and correctly sized
Earth bars and connections are clean and tight
RCDs trip within their rated time when tested with a proper instrument
RCD test results are recorded with dates and readings
Socket outlets likely to feed outdoor or portable equipment are RCD protected
Building Your Commercial Electrical Inspection Checklist
Start with the physical walk-round, then layer testing and documentation on top. A commercial electrical inspection checklist that only covers one of those three will leave gaps.
A practical sequence looks like this:
Walk the building. Note damaged sockets, cracked accessories, trailing leads and overloaded extension boards.
Open the boards. Look for heat damage, loose terminations and correct labelling.
Test. Use a multifunction tester for insulation resistance, earth continuity, polarity and RCD trip times.
Record. Log every reading against the circuit it belongs to.
Act. Flag defects by severity and set a date for each fix.
Commercial EICR Requirements Every Business Should Know
An Electrical Installation Condition Report (EICR) is the formal inspection and testing document for fixed wiring. It records the condition of the installation, lists any defects, and gives a date by which the next inspection is due.

For commercial premises, the legal framework sits with the Electricity at Work Regulations 1989, which require electrical systems to be maintained so as to prevent danger. There's no single statutory interval for every business, but the EICR itself recommends one based on the installation's condition and use.
What the report covers:
Condition of the fixed installation, circuit by circuit
Defect codes: C1 (danger present), C2 (potentially dangerous), C3 (improvement recommended), FI (further investigation)
The overall assessment, either satisfactory or unsatisfactory
A recommended date for the next inspection
If you're wondering how long the inspection itself takes, our guide on how long an EICR takes walks through the timescales by property size and circuit count.
Portable Appliance Testing Checklist for Workplace Equipment
Portable appliance testing (PAT) covers anything with a plug that isn't part of the fixed installation: kettles, monitors, chargers, power tools, extension leads. A portable appliance testing checklist should confirm the following for each item:
Plug and cable are free from damage, fraying or exposed conductors
The fuse is the correct rating for the appliance
The casing is intact with no cracks
Earth continuity passes on Class I equipment
Insulation resistance passes
Test date and result are recorded on a label or register
The Health and Safety Executive guidance on electrical safety is clear that the frequency of testing should be risk-based. A desktop monitor in an office rarely needs the same attention as a power tool used daily on a site.
What most guides miss is the register. A sticker on the plug fades, falls off or gets swapped between items. The written register is what proves the test happened.
Using an Electrical Inspection Report Template to Record Findings
An electrical inspection report template is a structured form that captures what was checked, what was found, and what needs fixing. The template matters because it forces consistency: every board, every circuit and every defect gets recorded the same way, whoever carries out the inspection.
A workable template should hold:
Field | What it records | Why it matters |
Location and board reference | Where the check took place | Proves coverage across the whole site |
Circuit details | Rating, type and purpose | Matches findings to the right circuit |
Test readings | Insulation, continuity, RCD times | Evidence the test was actually done |
Defect code | C1, C2, C3 or FI | Sets repair priority |
Remedial action | What was done and when | Closes the loop |
Inspector and date | Who signed it off | Accountability |
If you use contractor software or a downloaded template, check it captures all six fields. A template that skips test readings gives you a tick-box exercise, not a compliance record.
How Often Should Commercial Electrical Safety Checks Happen?
There's no fixed legal interval for commercial electrical safety checks. The right frequency depends on the installation's age, condition, use and environment, and the EICR should recommend the next inspection date based on what it finds.
Fixed wiring EICR: based on the recommendation in the last report, often shorter for older or heavily loaded installations
PAT: risk-based, from annual for power tools to several years for low-risk office equipment
User checks: visual inspection of plugs and leads by staff, ongoing
Formal visual inspection: more frequent than full testing, especially in harsh environments

Frequently Asked Questions
What should a commercial electrical safety checklist include?
A working checklist should cover fixed wiring and distribution boards, earthing and bonding, RCD and circuit protection, socket outlets, emergency lighting, portable appliance testing and a record of previous inspection dates. It should also note who carried out each check and when the next one is due. A commercial electrical safety checklist is only useful if it produces a dated record you can show an insurer, landlord or enforcing authority.
How often should commercial electrical installations be inspected?
The interval depends on the premises. Offices, shops and other low-risk commercial sites are commonly inspected every five years, while industrial units, workshops and sites with heavy equipment or harsh conditions often need checks every three years or sooner. The previous EICR will state a recommended next inspection date. If no report exists, treat the installation as overdue and arrange one.
Who is responsible for electrical safety in commercial premises?
The duty holder is whoever controls the premises or the electrical system, which is usually the business owner, landlord or facilities manager. Under the Electricity at Work Regulations 1989, that person must keep electrical systems maintained so they do not cause danger. In practice this means arranging inspections, acting on faults and keeping records. Responsibility is not transferred by hiring a contractor; it is only supported by one.
What should you do if an electrical inspection identifies a fault?
The EICR grades findings as C1, C2 or C3. A C1 is immediate danger and needs urgent isolation and repair. A C2 is potentially dangerous and must be fixed, usually before the report can be classed as satisfactory. A C3 is an improvement recommendation. Get written confirmation of what will be repaired, by whom and when, and keep the updated certificate with your inspection records.
Are portable appliances included in commercial electrical safety checks?
They can be, but they are usually handled as a separate portable appliance testing checklist rather than part of the fixed wiring EICR. PAT covers kettles, chargers, extension leads, power tools and similar equipment. The required frequency depends on the appliance and how it is used, with construction and heavy-use equipment tested far more often than office IT. Record every test, including pass, fail and disposal.
Most businesses don't discover the gaps in their electrical compliance until an inspection, an insurer or an incident forces the issue. Bright Sparx Electrical closes those gaps with certified in-house work, a free full inspection and clear pricing from the outset.
