EICR stands for Electrical Installation Condition Report.
An EICR is a formal report produced following an inspection and test of a property’s fixed electrical installation. It assesses the installation’s condition, identifies electrical safety concerns and records defects requiring attention.
The report helps property owners and dutyholders understand whether the electrical installation is in a satisfactory condition for continued use.
A commercial EICR may include inspection of:
The completed Electrical Installation Condition Report (EICR) records inspection findings, electrical test results, observations, any agreed limitations and the recommended date for the next inspection.
An EICR certificate is the commonly used name for the Electrical Installation Condition Report issued after electrical inspection and testing.
People also refer to this document as:
These terms are often used interchangeably, although the formal document for an existing installation is an Electrical Installation Condition Report. An EICR is different from an Electrical Installation Certificate, which is associated with qualifying new installation work or alterations.
For commercial properties, the purpose of an EICR is to identify electrical safety defects and help responsible persons make informed decisions about maintenance and corrective work.
It can support:
An EICR does not guarantee that an installation will remain fault-free indefinitely. It documents the condition of the installation at the time of inspection, subject to the stated scope and limitations.
Fixed wire testing is the inspection and testing of the permanent electrical installation within a building. A commercial fixed wire test examines wiring and associated equipment to identify damage, deterioration, potentially unsafe conditions and defects affecting electrical protection. Fixed wire testing is commonly undertaken as part of an EICR.
Fixed wire testing involves appropriate visual checks and electrical measurements of a building’s permanent electrical installation.
Depending on the installation, testing may include:
A fixed wire testing certificate is a common search term for the EICR report produced following the inspection.
Fixed wire testing assesses the permanent electrical installation, while Portable Appliance Testing (PAT) concerns portable and transportable electrical equipment.
Fixed Wire Testing | PAT Testing |
Fixed electrical cables | Portable electrical appliances |
Distribution boards | Portable electrical tools |
Socket and lighting circuits | Office appliances |
Earthing and bonding | Portable equipment inspection |
Electrical protective devices | Appliance-specific electrical checks |
EICR report | PAT inspection and test records |
An EICR does not automatically include PAT testing.
Fixed appliance testing is another related term, but fixed or stationary electrical equipment may require additional equipment-specific inspection and maintenance outside the scope of an installation EICR. Safety Spectrum London can discuss separate PAT testing and fixed electrical installation inspection services.
Safety Spectrum London provides single-phase and three-phase EICR testing for commercial electrical installations throughout London. Both supply arrangements can be inspected and reported through an EICR, although the electrical systems and testing requirements may differ.
A single-phase EICR involves inspection and testing of an installation using a single-phase electrical supply.
A typical UK single-phase supply includes:
Single-phase supplies are frequently used in houses, flats, small offices, shops and other relatively low-demand premises.
A three-phase EICR assesses an electrical installation supplied by three live phase conductors, commonly identified as L1, L2 and L3. Three-phase supplies are often used in larger commercial buildings, warehouses, industrial units and properties with significant electrical demand.
A typical UK low-voltage three-phase system uses:
Feature | Typical Specification |
Live Conductors | L1, L2 and L3 |
Neutral | Normally present in a four-wire system |
Protective Earth | Appropriate earthing arrangement |
Phase-to-Neutral Voltage | Approximately 230V |
Phase-to-Phase Voltage | Approximately 400V |
Frequency | 50 Hz |
The current rating of a three-phase supply depends on the incoming supply arrangements and distribution equipment.
Three-phase systems are commonly found in:
No. A three-phase electrical installation is inspected and reported using an Electrical Installation Condition Report. Three-phase describes the electrical supply, not a different certification category. Both single-phase and three-phase inspections result in an EICR.
Depending on the installation, a three-phase EICR may include:
Feature | Single-Phase EICR | Three-Phase EICR |
Phase Conductors | One | Three |
Typical Voltage | 230V | 230V/400V |
Common Properties | Homes, Small Shops | Larger Commercial Buildings |
Electrical Demand | Often Lower | Often Higher |
Distribution Equipment | Usually Simpler | May Be More Complex |
Report Issued | EICR | EICR |
Testing Cost | Installation-Dependent | Installation-Dependent |
Three-phase testing may require more time when multiple distribution boards, extensive circuits or specialised electrical equipment are present.
All tests performed comply with written RAMS (Risk Assessment & Method Statement) for total HSE compliance.
Our qualified electricians conduct all commercial EICRs with little disruption.

If issues arise, we quote and complete works promptly to issue a Satisfactory EICR Certificate.
An EICR report provides a structured record of an electrical installation inspection.
A completed report generally includes:
An EICR contains a summary of the installation’s condition and supporting technical information. Customers should pay particular attention to the overall assessment, observation codes, recommendations and any inspection limitations.
An EICR is normally issued using an appropriate inspection and testing report format containing the required schedules and declarations. It is not simply a generic electrical safety certificate template that can be completed without inspecting the installation. The findings must be based on work carried out by a competent person.
EICR classification codes explain the nature and urgency of electrical safety observations.
Code | Meaning | Required Response |
C1 | Danger Present | Immediate action |
C2 | Potentially Dangerous | Urgent remedial action |
C3 | Improvement Recommended | Improvement advised |
FI | Further Investigation Required | Investigate without delay |
If your commercial EICR identifies defects, Safety Spectrum London can provide electrical repairs and remedial services.
Our EICR remedial works may include:
After electrical remedial work, appropriate verification and testing must be carried out. Depending on the work completed, supporting documentation may include an Electrical Installation Certificate, Minor Electrical Installation Works Certificate or other relevant confirmation. A new satisfactory EICR is not automatically required or issued after every repair. The documentation depends on the original report, the defects and the work completed.
Commercial property owners and dutyholders must keep electrical installations safe. An EICR helps assess their condition, although commercial properties do not have a universal legal five-year EICR requirement.
These regulations require electrical systems to be maintained so as to prevent danger, so far as reasonably practicable. Inspection and testing can form part of a suitable electrical maintenance programme.
BS 7671 is the recognised UK standard covering requirements for electrical installations. The current published 18th Edition amendment is BS 7671:2018+A4:2026. A commercial EICR uses the applicable inspection and testing requirements to assess the installation’s safety. Older installations are not automatically unsafe simply because they were installed under an earlier edition.
Employers have general legal duties to manage risks affecting employees and others. Electrical maintenance and inspection can support these responsibilities.
Insurers, landlords and commercial leases may require evidence of electrical inspection and testing. The requirements depend on the individual insurance policy, lease and property circumstances.
The recommended interval between EICR inspections depends on the type of property, its electrical installation, usage and condition.
Many lower-risk commercial premises use a five-year inspection cycle, while industrial and specialist installations may require more frequent assessment.
Property Type | Typical Interval |
Commercial Offices | Often 5 Years |
Retail Shops | Often 5 Years |
Restaurants and Hotels | Often 5 Years |
Industrial Properties | Risk-Based |
Warehouses | Risk-Based |
Medical Locations | Specialist Requirements |
Swimming Pool Installations | Often Annually |
Owner-Occupied Homes | Often 10 Years Recommended |
Covered Rented Homes in England | Maximum 5 Years or Sooner if Required |
These intervals are not universal expiry periods. The recommended inspection date should be determined according to the electrical installation and relevant legal or technical requirements.
An EICR does not have one fixed validity period that applies to every property. The report records a recommended date for the next inspection. Changes in use, installation damage, serious faults or other circumstances may require earlier inspection.
For rented residential properties covered by England’s electrical safety regulations, inspection and testing are required at least every five years, or sooner if the report specifies. Commercial landlord responsibilities differ and depend on the relevant electrical safety duties, installation circumstances and lease arrangements.
A commercial EICR and a landlord residential EICR both assess the safety and condition of fixed electrical installations.
However, their property types and regulatory requirements may differ.
Commercial EICR | Residential Landlord EICR |
Offices, Shops, Warehouses | Rented Houses and Flats |
Single or Three-Phase Systems | Usually Single Phase |
Workplace Electrical Safety | Residential Electrical Safety |
Risk-Based Inspection Frequency | Statutory Maximum Usually 5 Years for Covered Tenancies |
Commercial Installation Report | Residential Installation Report |
A landlord electrical safety certificate commonly refers to the EICR obtained for a rented residential property. An electrical safety certificate for landlords helps demonstrate that the property’s fixed electrical installation has been inspected and tested. also provides residential EICR testing and landlord electrical safety inspection services.
