For developers active in Longfield, the distinction between an EIC and an EICR matters. New circuits — whether on a greenfield site or in a refurbishment — get an Electrical Installation Certificate at the point they’re commissioned. An EICR comes in later, on existing installations, as periodic inspection evidence. Knowing which document applies at which stage of a development is half the compliance work; CJA Electrical handles both sides.

What an EICR involves for Developer

A developer EICR follows the same regulatory standard as any domestic EICR (BS 7671:2018+A2:2022) but is most often commissioned in one of three contexts: ahead of a refurbishment to document the starting condition; after refurbishment of a pre-existing installation, where the existing wiring has been adapted but not replaced; or as periodic inspection on a phased development whose earlier phases are already occupied. New circuits don’t get an EICR — they get an EIC at commissioning. We do both, with the right document for the right job.

When you need this in Longfield

The triggers for a developer EICR aren’t the same as for a landlord EICR. Most often: an acquisition where the existing electrics need due-diligence inspection before completion; a refurbishment where the existing wiring is being kept in part and the developer needs evidence of its condition; or a phased development where some plots are already lived in and periodic inspection is due on the older phases. None of these scenarios fit the standard “rented property, every five years” template — they’re project-specific.

What the report contains

Standard three-part EICR deliverable: form, schedule of inspection, schedule of test results. For phased developments, we’ll commonly supply a plot-by-plot summary alongside the individual reports so the developer’s project tracker has a single overview document. Where new circuits sit alongside retained wiring, we’ll issue the appropriate EIC for the new work in addition to the EICR for the retained installation. Two documents, two purposes.

Why book CJA Electrical for your Longfield EICR

For developer work, the value is in getting the documentation right. EIC where it should be an EIC, EICR where it should be an EICR, all formatted correctly for Building Control sign-off and for the eventual buyer’s solicitor. CJA Electrical works to BS 7671:2018+A2:2022 with a City & Guilds 2391 qualified inspector, fully insured, ten years on Dartford projects. Reports back within 48 hours of testing; remedial quotes attached where needed.

How the inspection runs

  1. Project scope conversation — what’s being inspected, where it sits in the project programme, what other trades are on site 2. Quote with appointment options that fit the project programme 3. On-site inspection — coordinated with the site manager or principal contractor as needed 4. Written report (PDF) supplied within 48 hours 5. Where new circuits are involved, EIC issued separately at commissioning 6. Remedial work quoted alongside any unsatisfactory findings; re-test on completion

What affects the price

Developer EICR work is priced per inspection scope. Refurbishment baseline EICR on a single dwelling is priced like a domestic EICR. Phased-development work is priced per plot or per block depending on what’s being inspected. EIC work for new circuits is priced separately by circuit count.

FAQs

When during a refurb do I need an EICR vs an EIC?

Existing wiring being kept and adapted as part of a refurbishment is the EICR domain — the report documents the condition of what’s being retained. New circuits added during the refurbishment get their own EIC at the point they’re commissioned. A typical refurb often produces both documents — EICR for the retained installation, EIC for the new circuits.

What’s the difference between a Minor Works Certificate and an EICR?

A Minor Works Certificate (MWC) is issued for small additions to an existing installation that don’t constitute a new circuit — for example, adding an extra socket on an existing ring main. The MWC documents the modification and confirms it doesn’t compromise the installation’s safety. An EICR is a full periodic inspection of every accessible part of the installation; the two cover very different scopes.

Do you handle EIC issuance alongside EICR work on a project?

Yes. Most developer projects mix retained and new installation work. We’ll issue the EICR for the retained sections and EICs for the new circuits, with both documents formatted for Building Control sign-off and for the eventual buyer’s conveyancing. Single point of contact for both, single project invoice.

Can you work alongside other trades on a live site in Longfield?

Yes. Most of our developer work happens on live sites with other trades present. We coordinate with the site manager or principal contractor to fit the inspection slot into the wider programme, and we work to the site’s H&S and access protocols. Longfield sites are reached from our Rochester base in around 30 minutes.

Do you supply documentation in a format Building Control accepts?

Yes. EICs and EICRs follow the standard BS 7671 formats that Building Control bodies accept across England. Standard three-part EICR PDF — form, schedule of inspection, schedule of test results — and standard EIC for new circuits with the matching schedule of test results.

How quickly can you turn EICR work round on a developer project?

Same-week appointments are typical for Longfield projects, with the report PDF in the project inbox within 48 hours of the visit. For phased developments where multiple plots need inspecting, we batch the visits to keep the cost down and the turnaround tight. Tighter timelines are possible where the project programme demands it.
