An 18th Edition certificate is a phrase people often use when talking about electrical testing, BS 7671 wiring regulations, EICR reports or electrical installation certificates.

Strictly speaking, the 18th Edition refers to BS 7671, the UK wiring regulations used for electrical installations. It is not one single certificate for every electrical job. Instead, electrical work and inspection may result in different certificates or reports depending on what has been carried out.

Common documents include:

  • Electrical Installation Certificate
  • Minor Electrical Installation Works Certificate
  • Electrical Installation Condition Report
  • EICR report
  • test result schedules
  • circuit details
  • Building Regulations compliance notification where required

If you are a landlord, homeowner, buyer, property manager or business, the certificate you need depends on whether the work is a new installation, minor electrical work, inspection and testing, or a landlord electrical safety check.

Key Takeaways

  • The 18th Edition Certificate validates compliance with BS 7671:2018 standards for electrical installations in the UK.
  • Mandatory for electricians and electrical engineers to ensure safety and legal compliance in their work.
  • Obtained through the City & Guilds 2382-22 course, involving training and a passing score on the final exam.
  • The certification requires renewal to keep up with amendments, like the A2:2022 update for addressing new technologies.
  • Course fees range from £100 to £350, not including additional costs for materials and exams.

An 18th Edition certificate usually means an electrical certificate or report completed in line with BS 7671 Wiring Regulations.

It may refer to:

Certificate / ReportWhen It Is Used
Electrical Installation CertificateFor new electrical installations or major alteration work
Minor Electrical Installation Works CertificateFor small additions or alterations to an existing circuit
Electrical Installation Condition ReportFor inspection and testing of an existing installation
EICRCommon name for an Electrical Installation Condition Report
Building Regulations notificationFor notifiable domestic electrical work where required

The correct document depends on the type of electrical work or inspection.

18th Edition Certificate

No. An EICR is an Electrical Installation Condition Report. It is used to assess the condition of an existing electrical installation.

The 18th Edition is the wiring regulation standard used by electricians when assessing, installing, inspecting or testing electrical installations.

In simple terms:

  • 18th Edition = wiring regulations standard
  • EICR = report on the condition of an existing installation
  • Electrical Installation Certificate = certificate for new installation work
  • Minor Works Certificate = certificate for smaller electrical works

18th Edition test certificates usually refer to electrical certificates or reports completed in line with BS 7671 Wiring Regulations, commonly known as the 18th Edition. These documents are used to record the inspection, testing, condition, and safety of an electrical installation.

They may include details such as the property address, client or owner information, electrician or company details, circuit information, inspection findings, test results, protective device details, earthing and bonding arrangements, observations or defects, the final declaration or assessment outcome, and any recommendation for the next inspection where required.

The IET provides BS 7671 model forms for certificates and reports, including Electrical Installation Certificates, Electrical Installation Condition Reports, and Minor Electrical Installation Works Certificates.


TheThe right certificate depends on the situation.

SituationLikely Document Needed
Landlord electrical safety checkEICR
Buying or selling a propertyEICR may be requested
New consumer unit installedElectrical Installation Certificate plus notification where required
New circuit installedElectrical Installation Certificate
Small alteration to existing circuitMinor Electrical Installation Works Certificate
Existing installation inspectionEICR
Remedial work after failed EICRCertificate or minor works document depending on work

Do not ask only for an “18th Edition certificate” without explaining what work has been done. The electrician needs to know whether you need inspection, testing, installation certification or remedial documentation.

18th Edition Certificate

For landlords, the most common electrical document is an EICR.

Government guidance says landlords must have electrical installations checked at least every 5 years by a properly qualified person and provide the required report where applicable.

A landlord may need an EICR for:

  • rental properties
  • tenancy compliance
  • managing agent records
  • HMO compliance
  • remedial work follow-up
  • property safety evidence

If the EICR finds defects, remedial work may be needed before the installation can be treated as satisfactory.


If a new consumer unit or fuse box is installed, this is not the same as an EICR.

A consumer unit replacement normally needs proper installation testing and certification. Planning Portal confirms that installing a new consumer unit or fuse box is notifiable electrical work under Building Regulations in England and Wales.

After this type of work, the customer may receive:

  • Electrical Installation Certificate
  • circuit schedule
  • test results
  • Building Regulations compliance notification where required

This is different from an EICR, which reports on the condition of an existing installation.

18th Edition Certificate

ObtaiElectrical certificates and reports should be completed by a competent electrician or electrical contractor with the right knowledge, testing equipment and experience.

A suitable electrician should understand:

  • BS 7671 Wiring Regulations
  • inspection and testing procedures
  • EICR coding
  • electrical safety defects
  • circuit testing
  • consumer unit requirements
  • earthing and bonding
  • landlord electrical safety duties
  • certification and reporting requirements

For landlords and businesses, using a competent electrical contractor helps reduce compliance and safety risks.


There are two different meanings people mix together.

TermMeaning
18th Edition qualificationA qualification showing an electrician understands BS 7671 Wiring Regulations
18th Edition certificateInformal phrase sometimes used for electrical test certificates
EICR certificateCommon phrase for Electrical Installation Condition Report
Electrical Installation CertificateCertificate for new installation work
Minor Works CertificateCertificate for minor electrical work

A homeowner or landlord usually does not need a City & Guilds 18th Edition course certificate. They usually need an EICR, Electrical Installation Certificate or Minor Works Certificate depending on the job.
