If you own or manage a commercial building, you're responsible for keeping its electrics safe. Commercial EICR testing is how you prove that. It's a formal inspection of your fixed wiring, carried out by a qualified electrician, and it gives you the paperwork regulators, insurers and tenants expect to see.
This guide explains what gets checked, what your report and certificate actually mean, and how often you need testing. For the full picture on compliance checks across your building, see our inspection and testing services.
What is commercial EICR testing?
EICR stands for Electrical Installation Condition Report. It's a detailed assessment of the fixed electrical installation in your property: the wiring, consumer units, sockets, switches and circuits built into the building.
The inspection looks for damage, wear, overloading and anything that could cause a fire or shock. Once done, you get a report setting out the condition of the installation and any faults found.
Think of it as an MOT for your building's electrics. It tells you what's safe, what needs attention, and whether the installation meets current standards.
Why commercial EICR testing matters
Faulty wiring is a real risk. It causes fires, injuries and costly downtime. A failed inspection, or no inspection at all, can also invalidate your insurance and leave you exposed legally.
Here's what regular testing gives you:
- Proof your installation is safe for staff, customers and tenants
- Documentation for insurers, auditors and landlords
- Early warning of faults before they become dangerous
- Confidence you're meeting your legal duties
Under the Electricity at Work Regulations 1989, you must keep electrical systems in a safe condition. An EICR is the recognised way to show you're doing that. It sits alongside other compliance checks, like Legionella and water safety testing, as part of keeping your building safe and signed off.
What's checked during the inspection
Your electrician works through the installation methodically. The inspection covers both visual checks and electrical testing with specialist equipment.
A typical commercial EICR looks at:
- Consumer units and distribution boards
- Wiring condition and cable type
- Earthing and bonding arrangements
- Signs of overheating, damage or overloading
- Circuit protection and fuse ratings
- Socket outlets, switches and accessories
Some circuits need to be switched off during testing, so the work is usually planned around your opening hours to keep disruption low.
Understanding your EICR report
Once testing is finished, you receive your commercial electrical inspection report. It records every observation and gives each one a classification code.
These codes tell you how serious each issue is:
- C1 (danger present): A risk of injury exists. Immediate action is required.
- C2 (potentially dangerous): The fault could become dangerous and needs urgent repair.
- C3 (improvement recommended): Not dangerous now, but worth putting right.
- FI (further investigation): The issue needs a closer look.
An installation with any C1 or C2 codes is marked 'unsatisfactory'. You'll need remedial work before it passes. A report with no C1 or C2 issues is 'satisfactory'.
Report versus certificate
People often mix these up. The EICR report for your commercial property describes the condition of an existing installation. A commercial electrical inspection certificate, such as an Electrical Installation Certificate, is issued when new work is installed.
Put simply: the report checks what's already there, the certificate signs off new work.
How often do you need an EICR?
There's no single answer for every building. The right interval depends on the type of property and how it's used.
As a general guide:
- Commercial premises: every five years, or at change of tenancy
- Industrial sites: every three years
- Rented properties: typically every five years
Your electrician will recommend a next inspection date on the report itself. High-use or higher-risk environments often need testing more frequently.
What happens if you fail
A failed EICR isn't a disaster, but you shouldn't ignore it. C1 and C2 issues must be put right by a qualified electrician.
Once the remedial work is done, your installation is retested. You then receive an updated, satisfactory report to keep on file.
The sooner faults are fixed, the sooner your building is safe and compliant again. If the work points to wider problems, our electrical inspection and testing team can handle the repairs too. Electrics rarely sit in isolation, so it's worth keeping your gas services and boiler servicing in check at the same time.
