A commercial EICR commonly remains current for up to five years, but five years is not a universal expiry period for every commercial property.
The most important date is the recommended date of the next inspection recorded on the report. An electrician may recommend a shorter interval where the installation is older, heavily used, exposed to difficult environmental conditions or has a history of defects.
UK workplace law requires electrical systems to be maintained so that they do not present danger. It does not impose one identical EICR interval on every office, shop, warehouse, restaurant or industrial property. The correct interval should reflect the installation’s condition, use and risk.

Commercial EICR Validity: Quick Answer
| Question | Answer |
|---|---|
| How long does a commercial EICR normally last? | Commonly up to five years |
| Is five years mandatory for every commercial property? | No, there is no single statutory interval for every commercial installation |
| Can an electrician recommend less than five years? | Yes, where the condition, use or environment justifies an earlier inspection |
| Which date should be followed? | The next inspection date stated on the latest EICR |
| Can an earlier inspection be needed? | Yes, after serious damage, major alteration, a significant change of use or other safety concerns |
| Does an unsatisfactory report remain valid for five years? | No. C1, C2 and FI observations require action rather than waiting until the next routine inspection |
For many ordinary business premises, a five-year inspection cycle is widely used as an initial benchmark. The electrician completing the EICR must still determine the next date from the actual installation and inspection findings.
Does a Commercial EICR Have a Fixed Expiry Date?
An EICR does not operate like a document that always expires after the same fixed period.
The report records:
- the date of the inspection
- the condition of the installation at that time
- the extent and limitations of the inspection
- electrical test results
- observations and classification codes
- whether the result is satisfactory or unsatisfactory
- the recommended date of the next inspection
The recommended interval should take account of the installation type, its use and operation, maintenance standards and the external conditions to which it is exposed. Subsequent inspection dates are set by the competent person carrying out the inspection and testing.
This means that two commercial properties inspected on the same day may receive different recommended dates.
Is a Five-Year Commercial EICR a Legal Requirement?
There is no general UK law stating that every commercial property must obtain an EICR at exactly five-year intervals.
The Electricity at Work Regulations 1989 require electrical systems used in work activities to be constructed and maintained, so far as reasonably practicable, to prevent danger. Periodic inspection and testing is one of the principal ways a business or property dutyholder can assess and document the condition of a fixed electrical installation.
A commercial EICR may also be required by:
- the terms of a commercial lease
- a premises licence
- a property-management agreement
- internal health and safety procedures
- a risk assessment
- an authority responsible for the premises
- contractual or due-diligence requirements
The legal duty is therefore broader than simply obtaining a report every five years. The responsible party must ensure that the electrical installation is maintained safely throughout the period between inspections.
For the wider legal position, read our commercial property EICR requirements guide.
Why Might a Commercial EICR Be Recommended for Less Than Five Years?
A shorter interval may be appropriate where the installation is exposed to greater use, deterioration or risk.
The electrician may consider:
- the age and condition of the installation
- the results of the current and previous EICRs
- frequent electrical alterations or tenant fit-outs
- high electrical loads
- machinery or specialist equipment
- moisture, dust, heat, vibration or corrosive conditions
- frequent public access
- inadequate maintenance records
- evidence of damage or overheating
- the consequences of an electrical failure
- restrictions or limitations during the inspection
The interval should be based on professional assessment rather than applying the same number of years to every property. The IET states that the type and use of the installation, maintenance quality and external influences must be considered when setting inspection intervals.
When Should a Commercial EICR Be Arranged Earlier?
You should not always wait until the next inspection date where something significant has changed.
An earlier inspection or specialist electrical assessment may be appropriate after:
- fire, flooding or water ingress
- electrical burning smells or signs of overheating
- repeated tripping or unexplained electrical faults
- damage to wiring, distribution boards or accessories
- substantial refurbishment
- a major change in the property’s use
- installation of high-load machinery or equipment
- extensive tenant alterations
- long periods without suitable electrical maintenance
- discovery of unsafe or undocumented electrical work
Minor properly certified electrical work does not automatically require a complete new EICR. However, substantial changes or safety concerns may mean the existing report no longer provides a sufficient picture of the installation’s current condition.
Does an Unsatisfactory Commercial EICR Last Five Years?
An unsatisfactory EICR should not be treated as acceptable until the next routine inspection date.
An EICR is normally considered unsatisfactory where it includes:
These observations require immediate or urgent attention. A C3 observation means improvement is recommended and does not, by itself, make the report unsatisfactory.
After remedial work, retain the original EICR together with the appropriate electrical certificates or written records showing what has been corrected. A complete repeat EICR is not automatically necessary after every individual repair, although one may be appropriate where the original inspection was heavily limited or the work was extensive.
Read our guide to EICR codes C1, C2, C3 and FI for a full explanation.
How to Check Whether a Commercial EICR Is Still Current
1. Find the Inspection Date
Check when the inspection and testing were completed. Do not rely only on the date the PDF was emailed or downloaded.
2. Find the Recommended Next Inspection Date
The report should state when the installation should next be inspected. This date is more reliable than assuming that every commercial report lasts five years.
3. Check the Overall Outcome
Confirm whether the report is marked satisfactory or unsatisfactory. An unsatisfactory report requires remedial action or further investigation.
4. Review the Limitations
Check whether areas, circuits or equipment were excluded because of access restrictions, operational requirements or an inability to isolate the electricity.
Significant limitations can reduce how much assurance the report provides.
5. Check the Remedial Records
Where previous defects were identified, confirm that suitable completion certificates or written remedial records are available.
6. Consider Changes Since the Inspection
Check whether the property has since undergone refurbishment, new circuit installation, machinery upgrades, tenant fit-outs, water damage or another material change.
An EICR records the installation’s condition at the time of inspection. It does not certify future alterations that were completed afterwards.
Does a Commercial EICR Transfer to a New Owner or Tenant?
A change of owner, landlord or commercial tenant does not automatically erase the findings of an existing report.
The EICR relates to the electrical installation at the address and records its condition on the inspection date. A purchaser or incoming tenant may therefore review an existing report as part of property due diligence.
However, the incoming party should confirm:
- that the next inspection date has not passed
- that remedial work was completed
- whether alterations were made after the inspection
- whether the report contained substantial limitations
- who is responsible for future electrical maintenance
- whether the lease requires a more recent report
Responsibility for electrical safety in a commercial property can depend on control of the installation and the wording of the lease. Commercial tenants have some legal responsibilities, but many property duties are determined by the lease agreement.
Who Is Responsible for Renewing a Commercial EICR?
Responsibility may rest with the:
- freeholder
- commercial landlord
- tenant
- managing agent
- facilities-management company
- employer or business occupying the premises
- party controlling a particular part of the installation
For multi-let buildings, one party may control the communal electrical installation while individual tenants control the installations within their units.
The lease, maintenance agreement and actual level of control should be reviewed before arranging the inspection. The party responsible for workplace safety should not assume that someone else has completed the required inspection without obtaining evidence.
How to Prepare for the Next Commercial EICR
Before the electrician attends:
- locate the previous EICR and remedial records
- provide circuit charts and installation certificates where available
- clear access to distribution boards and electrical cupboards
- arrange keys, access permissions and escorts
- identify critical equipment that cannot be switched off
- agree suitable shutdown periods
- notify tenants, employees and contractors
- provide details of known faults or recent alterations
Commercial testing may require temporary circuit isolation. Planning access and shutdowns in advance can reduce limitations and avoid an unnecessary return visit.
Frequently Asked Questions
How long does a commercial EICR normally last?
For many commercial properties, an interval of up to five years is commonly recommended. The actual date to follow is the next inspection date written on the report.
How often should a commercial EICR be carried out?
The interval should be based on the type, use, condition and environment of the installation. It may be five years or a shorter period recommended by the inspector.
Is a five-year electrical test legally required for commercial premises?
There is no single five-year statutory rule covering every commercial property. The law requires workplace electrical systems to be maintained to prevent danger.
Can a commercial EICR last only three years?
Yes. An inspector may recommend three years or another shorter interval where the property’s condition, environment, usage or risk justifies more frequent inspection.
Does changing commercial tenants require a new EICR?
Not automatically. The existing report, lease requirements, alterations, remedial records and current condition should be reviewed before deciding whether another inspection is needed.
What happens when the commercial EICR date has passed?
The responsible party should arrange a new inspection promptly. An overdue report may leave the business unable to demonstrate that the fixed installation has been appropriately inspected and maintained.
