Electrical Certificates After a Rewire

After a house rewire, the electrical certificate and the Building Regulations record are two different documents. For a complete domestic rewire, expect an Electrical Installation Certificate with its schedules of inspections and test results. Because rewiring is notifiable work in England, there should also be a Building Regulations compliance record from the agreed approval route.

Keep both with the quotation, invoice and any useful route drawings or photographs. The documents answer different questions: what electrical work was designed, installed, inspected and tested, and how the notifiable work was recorded for Building Regulations. JI Electrical's full and partial rewiring service in Cirencester covers the electrical scope. Ask which certification and notification route will apply before work begins.

The rewire paperwork at a glance

A tidy handover file is easier to check when each item has a defined purpose. The certificate title matters. An invoice can describe what you paid for, but it is not an electrical certificate. An Electrical Installation Condition Report records the condition of an installation at the time of inspection, but it is not the installation certificate for a newly completed rewire.

The IET's current model forms show an Electrical Installation Certificate, a Minor Electrical Installation Works Certificate and an Electrical Installation Condition Report as separate forms. For a complete rewire, the relevant handover document is the Electrical Installation Certificate, not a Minor Works Certificate.

What the Electrical Installation Certificate should tell you

The Electrical Installation Certificate is often shortened to EIC. Its first job is to identify exactly what the certificate covers. A complete rewire can be recorded as a new installation, while an addition or alteration may cover only defined parts. Read the description and extent rather than relying on the word “certificate” at the top.

The IET model form separates responsibility for design, construction, and inspection and testing. It also records supply characteristics, earthing arrangements, protective devices and the recommended interval before the next inspection. The attached schedules are part of the record, not optional background paperwork. The model certificate states that it is valid only when the relevant schedules of inspections and test results are attached.

Check these six points before filing the EIC:

1. 1
   Address and client details

   The installation address should be the property that was rewired, without a wrong flat number or copied address.

2. 2
   Description and extent

   The scope should make clear whether the certificate covers the whole installation or only stated circuits, rooms or alterations.

3. 3
   Responsible people

   Names, dates and signatures should be present for the design, construction, and inspection and testing responsibilities that apply.

4. 4
   Inspection schedule

   Confirm that the schedule is attached and that any limitation or departure is stated rather than left ambiguous.

5. 5
   Test results

   The circuit schedule and measured results should be complete and legible, with circuits described so they can be identified later.

6. 6
   Next inspection

   Note the recommended interval and keep the certificate where a future owner or electrician can find it.

The certificate is evidence about the work covered at the time it was completed. It is not a promise that no fault can ever develop and it does not describe work outside its stated extent. If your project was partial rather than a complete replacement, use the full or partial rewire guide to check that the boundary between replaced and retained circuits is clearly recorded.

Why there is a separate Building Regulations record

Part P applies to electrical installation work in dwellings in England. The current Approved Document P page on GOV.UK explains the design, installation, inspection, testing and information requirements, and when work needs notification. The Registered Competent Person Electrical guidance lists both full and partial rewires as notifiable work in England.

The approval route should be settled before work starts. If the installer is registered for the relevant work with an authorised competent person scheme, the installer can self-certify and notify the local authority through the scheme. GOV.UK's competent person scheme guidance says the installer tells the authority where needed and supplies a certificate that can be used as evidence of compliance.

If that scheme route is not being used, the owner normally needs to arrange the appropriate building control route before the work starts. GOV.UK explains the available routes on its building regulations application page. A building control body may issue its own completion record when the requirements for that route are met. It does not issue the electrician's BS 7671 installation certificate in place of the person responsible for the work.

This article does not claim that JI Electrical belongs to any scheme. Ask Jack which route is proposed for your job, then verify any registration claim on the Registered Competent Person Electrical register. The seven checks before booking an electrician give a neutral checklist for registration, written scope and records.

An EIC is not an EICR

The similar initials cause avoidable confusion. An EIC certifies new installation work, an addition or an alteration. An EICR reports on the condition of an existing installation after periodic inspection and testing. The Registered Competent Person Electrical certificate table places a new circuit and a consumer unit replacement with an Electrical Installation Certificate, while a check for deterioration or damage produces an EICR.

A later EICR can be useful, but it does not recreate the design and construction declarations for a rewire completed by somebody else. It also may have agreed limitations because parts of an occupied or finished property cannot be inspected. If a contractor offers only an EICR after a complete rewire, ask in writing where the Electrical Installation Certificate and the Building Regulations record are.

JI Electrical also provides EICRs in Cirencester and the Cotswolds. That service has a different purpose from certification of new work. Landlords with an existing installation can use the landlord EICR guide for inspection cycles, report codes and remedial deadlines.

What to do if a certificate is missing or wrong

Start with the person or business that carried out the work. Send a short written list of what is missing: the EIC, inspection schedule, test schedule, Building Regulations record, or a correction to the property details or scope. Keep the request factual and attach the quotation or invoice so the job can be identified.

If a competent person scheme was used and the compliance record has not arrived, check the business and scheme operator on the official register, then contact that scheme operator. The register's homeowner benefits page explains that a registered electrician supplies the BS 7671 certificate and, for notifiable work, arranges the Building Regulations compliance certificate through the scheme operator.

If building control was the agreed route, contact the building control body named in the application. Do not assume that a new electrician can simply sign the original installer's declaration after the event. A different electrician can inspect the installation and report on its condition, but that is a different service and record. GOV.UK describes regularisation as a retrospective building control route for qualifying work already carried out without approval, and says alterations may be required before a local authority can agree compliance.

Missing records can affect a sale, insurance discussion or later electrical project. If you are buying a property with uncertain paperwork, ask the conveyancer what records have been produced and consider an independent condition assessment. The consumer unit upgrade guide explains why existing circuits and prior records matter before a board is replaced.

Keep a useful property electrical file

Store the certificate and schedules together, in paper form and as a backed-up digital copy. Add the final quotation, written variations, invoice, equipment instructions, photographs of concealed routes and any Building Regulations correspondence. Label the file with the property address and completion date.

Good records reduce guesswork when a kitchen, extension, EV charger or heating change is planned. They do not remove the need to inspect the installation, but they show what circuits existed, how they were tested and where the earlier certificate stopped. For later socket, lighting or power changes, see JI Electrical's lighting and power alterations service.

In a period property, keep the electrical file with any consent, conservation and concealed-route records. The older-home rewiring guide explains how the electrical plan, cable routes and protected building fabric fit together.

Before the rewire starts, put the handover requirements into the quotation. Name the Electrical Installation Certificate, its inspection and test schedules, the Building Regulations route and any drawings or photographs promised. That is clearer than asking generally for “all certificates” after the walls are closed and the project team has moved on.

For a rewiring enquiry in Cirencester or the Cotswolds, use the JI Electrical contact page and share the property type, occupancy, planned layout and any existing EICR or electrical certificate. You can also view recent JI Electrical project photographs. Jack can confirm whether the electrical work is within scope and what records the proposed job should produce.
