Key Takeaways
- UK workplace law does not set one universal EICR interval for every commercial property
- The next inspection date should reflect the installation, site risk, use, environment and previous findings
- C1 codes mean "danger present" and require immediate action
- The Electricity at Work Regulations 1989 require systems to be maintained to prevent danger; BS 7671 supports inspection and testing practice
- Wire Now provides EICR inspections and remedial works across London, Hertfordshire, and Essex
How Often Does a Commercial Property Need an EICR?
There is no single statutory EICR interval that applies to every UK commercial property. The Electricity at Work Regulations 1989 require electrical systems to be maintained so far as reasonably practicable to prevent danger, while HSE guidance says the quality and frequency of maintenance should be sufficient for that purpose.
The recommended date for the next inspection should be set by a competent person. It should reflect the installation's type and condition, how the premises are used, the environment, previous findings and the dutyholder's risk assessment. Lease, insurer or client requirements may also set a review point. If the installation changes, is damaged or develops faults, an earlier assessment may be appropriate.
What Do the EICR Observation Codes Mean?
When an inspector identifies an issue, they assign an observation code that indicates the severity:
| Code | Meaning | Required Action |
|------|---------|-----------------|
| C1 | Danger present | Immediate remedial action required — the inspector may disconnect the circuit |
| C2 | Potentially dangerous | Urgent remedial action required as soon as practicable |
| C3 | Improvement recommended | Not immediately dangerous but should be improved |
| FI | Further investigation | Additional investigation required to determine the extent of the issue |
A report containing C1, C2 or FI observations is normally assessed as unsatisfactory. The dutyholder should arrange appropriate action, retain the report and keep evidence of remedial work or further investigation.
What Legal Duties Apply to a Commercial EICR?
For workplaces, the core duty is to maintain electrical systems so they do not present danger. The Electricity at Work Regulations do not create a blanket commercial EICR fine or a universal three-year testing rule. Enforcement and any penalty depend on the applicable duty, the facts and the relevant enforcing authority.
The widely quoted £40,000 civil penalty relates to specified electrical-safety duties in the private and social rented housing sectors from 1 May 2026, as set out in GOV.UK rented-sector guidance; it should not be presented as a general penalty for every commercial property.
Property teams should also check lease and insurance terms. Those documents may require inspection records or evidence of maintenance, but the effect on cover depends on the policy and circumstances.
Where an inspector finds immediate danger, affected equipment or circuits may need to be isolated until the risk is made safe. Planning shutdowns and access before testing can reduce unnecessary disruption.
What Does an EICR Inspection Involve?
An EICR is a thorough examination of the fixed electrical installation in a building. The inspection covers:
- Consumer units and distribution boards — condition, labelling, RCD protection
- Wiring — type, condition, adequacy for current load
- Earthing and bonding — continuity, adequacy
- Socket outlets and switches — condition, polarity
- Lighting circuits — condition, protective devices
- External installations — outdoor lighting, signage circuits
The inspector will carry out visual checks, electrical testing with calibrated instruments, and sampling of circuits. For a commercial property, this means testing a representative sample of circuits across the building.
How Long Does a Commercial EICR Take?
The duration depends on the board and circuit count, installation complexity, available records, access and the shutdown window. Some circuits need temporary isolation, so the testing plan should identify critical loads and operating constraints before work begins. A scope review is the safest way to estimate time for a particular site.
How Much Does a Commercial EICR Cost?
EICR costs for commercial properties vary based on several factors:
- Size of the premises — larger buildings with more circuits take longer to inspect
- Number of distribution boards — each board and its associated circuits must be tested
- Age and condition of the installation — older installations may require more extensive testing
- Access constraints — restricted access areas (ceilings, risers, plant rooms) can add time
Guide prices start from £295 + VAT for a small commercial installation and £595 + VAT for a typical office, retail, warehouse or communal-area installation. A scope review confirms the board count, circuits, access and testing window before the final price.
