EICR, EIC and Minor Works Certificates Explained

An EICR reports the condition of an existing electrical installation, an EIC certifies new installation work, and a Minor Works certificate records qualifying additions or alterations to an existing circuit.

“Electrical safety certificate” is an informal umbrella term. The correct document depends on whether someone inspected existing electrics or completed installation work. EICR Certificates London helps customers distinguish these tasks. For notifiable domestic work in England, separate Building Regulations compliance paperwork also matters.

EICR, EIC or Minor Works: Which Document Matches Your Situation?

Choose by the purpose: checking existing wiring calls for an EICR, certifying new installation work calls for an EIC, and qualifying alterations to an existing circuit can use a Minor Works certificate.

Document	Typical trigger	Scope	Responsible signatory	Supporting records	What it does not establish
Electrical Installation Condition Report	Periodic assessment of existing wiring.	Recorded inspection extent and limitations.	Competent inspector responsible for the assessment.	Observations, inspection schedule, circuit details and test results.	Certification of original construction.
Electrical Installation Certificate	New installation, circuit, rewire or consumer unit replacement.	Described installation work.	Those responsible for design, construction and inspection/testing.	Inspection and circuit schedules, including measured results.	Automatic coverage of every retained part.
Minor Electrical Installation Works Certificate	Qualifying addition or alteration without providing a new circuit.	Identified work on an existing circuit.	Person authorised to certify the work.	Circuit particulars, relevant checks and embedded test results.	A whole-property condition assessment.

Separate notification question: Part P paperwork depends on the work and applicable route. The electrician determines the appropriate technical certificate; customers cannot substitute a shorter form for the required certification. These distinctions follow the IET’s BS 7671 model forms.

What Does an EICR Tell You About Existing Wiring?

An EICR records the condition of the fixed electrical installation within the inspection’s stated extent and limitations. Those boundaries explain what was assessed and any restrictions encountered; they do not mean every concealed cable was exposed. Read more about what an EICR covers and excludes. Fixed wiring, distribution equipment and accessories are distinct from portable appliances, which need their own appropriate checks.

An unsatisfactory outcome remains a valid record of the findings. Paying for testing does not purchase a satisfactory assessment. If you need to establish the condition of existing electrics, you can book an EICR inspection in London. Check that the complete report includes:

• The property details and inspection date.
• The overall satisfactory or unsatisfactory assessment.
• An observation schedule identifying findings and classifications.
• The inspection schedule, circuit information and schedule of test results.
• The recommended next inspection and recorded limitations.

When Should Electrical Work Produce an EIC?

An Electrical Installation Certificate records the design, construction, inspection and testing of the installation work described on it. New installations and circuits, rewires and replacement consumer units require this form of certification. Responsibility may be divided between different people: the declarations identify who takes responsibility for each role. Current work should use BS 7671:2018+A4:2026; interpret older records against their stated standard and date.

Consumer-unit example: Replacing a fuse box involves checking the connected circuits and documenting the replacement. Its EIC does not mean all existing cables were renewed. See consumer unit replacement and certification.

Rewiring example: Replacing selected circuits leaves other wiring in place. The certificate’s description should distinguish that partial scope from a whole-house installation. Discuss the extent required for full or partial rewiring.

At handover, look for:

• A clear description of completed work, including retained sections where relevant.
• Completed declarations identifying the responsible people.
• The accompanying inspection schedule and circuit test records.
• The recorded recommendation for subsequent inspection.

The certificate follows justified installation certification; it is not simply paperwork purchased separately from the work.

Is a Part P Certificate the Same as an EIC?

An EIC and a Building Regulations compliance certificate serve different purposes, so one should not be assumed to replace the other. “Part P certificate” commonly means the compliance paperwork associated with notifiable electrical work in an English home.

• EIC: technical declarations and inspection results for the installation described, based on BS 7671.
• Building Regulations document: evidence of compliance through the relevant notification route. Scheme self-certification produces compliance paperwork; a local authority building-control route produces completion documentation.

Installing new circuits and replacing consumer units are examples requiring notification. Other alterations need their own assessment of which electrical work is notifiable under Part P. Non-notifiable work still requires appropriate inspection, testing and certification.

Ask the installer which route applies and who will provide each record. Documents may come from different parties, so retain them together. GOV.UK Approved Document P explains these separate responsibilities. An ordinary EICR does not retrospectively supply missing notification.

What Can a Minor Works Certificate Cover?

A Minor Electrical Installation Works Certificate can record qualifying additions or alterations to an existing circuit where no new circuit is provided. It identifies the circuit, describes the change and records relevant checks. These may concern a ring final circuit or a radial circuit, including its circuit protective conductor and applicable test results.

Situation	Is Minor Works suitable?
Adding a socket to an existing circuit.	Potentially, where the actual alteration meets the form’s requirements.
Creating a circuit or replacing the consumer unit.	No. Installation certification requires an EIC.
Assessing the condition of the property’s fixed electrics.	No. That is an EICR task.

Which Documents Should You Keep After EICR Remedial Work?

Keep the original EICR, the certification appropriate to the remedial work, and written confirmation explaining which findings have been resolved.

1. Original report: retain the observation references, overall assessment and supporting schedules.
2. Investigation or repair records: connect each action to its finding, including the outcome of any FI investigation.
3. Appropriate certification: obtain an EIC for work such as a replacement board, or Minor Works documentation for a qualifying circuit alteration.
4. Written remedial confirmation: record the resulting position, including unresolved findings and any further action required.

Outstanding observations may require additional remedial work following an EICR. Investigation alone does not automatically produce an installation certificate. Equally, repairing one item does not close every issue recorded elsewhere.

Whether further inspection or a fresh report is needed depends on the completed work, available evidence and applicable requirements. For covered rented properties, GOV.UK landlord guidance requires the original report and written confirmation to be supplied to the tenant and local council. Keep the documents together so their relationship is clear.

Does an Electrical Installation Certificate Expire?

An EIC remains a record of the work certified on its date; it is not a promise that the installation will remain safe indefinitely. Keep it as installation history, while considering subsequent alterations, deterioration and the recommendation for later inspection.

A recent board-change certificate cannot automatically stand as a current assessment of all wiring. Periodic inspection duties are separate from the age of a certificate covering particular work. See EICR renewal periods and legal requirements for the applicable intervals and rental duties.

• Date: when was the certified work completed?
• Scope: which circuits or equipment did it cover, and what has changed since?
• Next inspection: what recommendation and property-specific requirements apply?

How to Identify and Check the Document You Have

Read the full document title, property details, date and scope before deciding what your certificate or report proves.

1. Type: identify whether you hold an EICR, EIC, Minor Works form or compliance record.
2. Address: confirm the correct property, including the individual flat or premises.
3. Date: distinguish the inspection date from the completion of installation work.
4. Extent: read what was included, retained or excluded.
5. Responsibility: check the declarations, names and signatures for the relevant roles.
6. Supporting pages: locate schedules or embedded measurements; for an EICR, also read the limitations, observations and outcome.
7. Notification: find separate Building Regulations evidence where the work required it.

An invoice or registration logo alone does not establish technical scope or prove authenticity. “IEE certificate” may refer to older Wiring Regulations paperwork: the IET’s history explains the earlier IEE terminology. Identify the actual title and date rather than treating this as a fourth current document category.

What Determines the Cost of an EIC or Minor Works Certificate?

The cost depends on the installation work, testing and certification required, so compare the scope of the electrical work rather than a price for paperwork alone. Consumer-unit replacements and rewires are quoted against their respective scopes. Assessing existing electrics is a different task from installing and certifying new work; requesting a duplicate is different again.

• What installation work does the quotation include?
• Which inspection and testing activities are covered?
• Will the appropriate certificate and supporting results be supplied?
• Does the quoted scope include any required notification arrangements?

Ask about the applicable route for Part P paperwork and any associated quoted charges.
