Electrical Maintenance Checklist: 10 Essential Checks

A commercial electrical maintenance checklist turns a vague legal duty into a routine your team can follow: quick weekly checks by staff, monthly and annual tests, and a full inspection of the fixed wiring at the interval your electrician recommends. This guide gives you a ten-point checklist, explains who should do each item and shows how to keep records that stand up.

The law behind it is short. The Electricity at Work Regulations 1989, regulation 4(2) says systems must be maintained, as necessary, to prevent danger so far as is reasonably practicable. It does not list tasks or intervals. A checklist is how you show you have thought about both.

Why You Need a Commercial Electrical Maintenance Checklist

Without a written plan, maintenance tends to happen only after something breaks. That costs more, and it leaves gaps nobody notices until an insurer, landlord or fire officer asks for evidence.

A commercial electrical maintenance checklist fixes three problems at once. It spreads tasks over the year, it makes clear who does what, and it creates a record every time a check is done.

The 10-Point Commercial Electrical Maintenance Checklist

Group the items on your commercial electrical maintenance checklist by how often they happen. Adjust the intervals to suit your premises and your risk assessment.

Weekly: quick visual checks by staff

1. Leads and plugs: look for cut or crushed cables, cracked plugs and taped repairs. Take damaged items out of use.
2. Sockets and switches: check for scorch marks, cracks, loose fronts or warmth.
3. Extension leads: remove daisy-chained leads and look for overloaded adaptors.
4. Distribution boards: covers closed, access clear, no stock stored in front, no burning smell.

HSE says that for most portable equipment in a low-risk workplace, low-cost user checks and visual inspections are a good way to maintain it.

Monthly: functional tests

5. Emergency lighting: a short functional test of each fitting, recorded in the log. The government guide for offices and shops recommends monthly tests and an annual test by a competent person.
6. Lighting and signage: replace failed lamps promptly, especially on stairs, exits and car parks.

Every six to twelve months: deeper checks

7. RCD test buttons: press the test button on each RCD at the interval shown on the notice at your board, and record the result.
8. Portable equipment review: decide which items need formal inspection and testing and how often, based on how they are used.

Annually and longer term: competent person checks

9. Annual emergency lighting test: a full-duration test by a competent person.
10. Fixed installation inspection (EICR): NICEIC strongly recommends business owners get an EICR at least every five years. Higher-risk sites may need it more often.

Who Should Do Each Item?

Split your commercial electrical maintenance checklist into two columns: what trained staff can do and what needs an electrician.

• Trained staff: visual checks, removing damaged items, monthly emergency lighting tests, pressing RCD test buttons and keeping the log.
• Qualified electrician: EICRs, annual emergency lighting tests, repairs, new circuits, board work and anything that involves removing covers.

Staff should never open boards, fit new sockets or repeatedly reset tripping breakers. If a breaker trips again after one reset, leave it off and report it.

Common Gaps in DIY Checklists

When we review a business’s own commercial electrical maintenance checklist, the same gaps appear again and again:

• No owner: the list exists, but nobody is named as responsible.
• No records: checks happen, but nothing is written down.
• Old EICR: the last report is out of date, or its C1 and C2 items were never fixed.
• Faults left open: problems are noted but not closed off.
• No review after changes: new equipment, layouts or tenants are added without updating the plan.

Each of these is easy to fix. Name one person, keep one log and review the list whenever the building changes.

Keeping Records

Your records are your evidence. For every item on the commercial electrical maintenance checklist, note the date, who did it, the result and any action taken.

Keep EICRs, installation certificates, emergency lighting logs and portable equipment records together. A simple spreadsheet or binder is fine, as long as it is up to date and easy to find.

Event-Based Checks to Add

Some checks are triggered by events, not dates. Add these to your commercial electrical maintenance checklist so they are not forgotten:

• After a leak or flood, keep affected equipment off until an electrician has checked it.
• After a refit or new partition walls, check emergency lighting coverage and socket provision.
• Before adding heavy loads, such as EV chargers or new machinery, confirm the supply and board can take them.
• After a change of tenant, ask for the current EICR and maintenance records.

Log these in the same way as the routine items, so the whole commercial electrical maintenance checklist lives in one place.

Rented and Multi-Tenant Premises

In shared buildings, check your lease to see who maintains what. Often the landlord covers the incoming supply and common areas, and each tenant covers their own unit.

Agree this in writing and share records. A joint commercial electrical maintenance checklist avoids items being missed because each side thought the other was responsible.

Turning the Checklist Into a Plan

A checklist works best as part of planned maintenance, where visits are booked in advance rather than after a failure. Our guide to planned vs reactive maintenance explains the difference.

Put each item in a calendar with a named owner. Then book your electrician’s visits, such as the annual emergency lighting test and the EICR, so they never slip.
