RCD and loop impedance testing in progress on a domestic circuit

Developer EICR work is more nuanced than landlord or homeowner work because the obvious question — “do I need an EICR on my new build?” — has a precise answer that’s often “no, you need an EIC”. CJA Electrical works with developers across Canterbury and the wider Canterbury area on the situations where an EICR is actually the right document: refurbishments of existing installations, change-of-use conversions where the wiring is being adapted rather than replaced, and periodic inspection of completed phases that have entered service.

What an EICR involves for Developer

Developer EICR scope is most often one of three things. Refurbishment of an existing installation: where the existing wiring is being kept and adapted rather than ripped out, an EICR confirms its current condition before the refurb goes live. Change-of-use conversion: a building being converted from commercial or single-dwelling to multiple dwellings, with the existing wiring carried forward in part. Phased completion handover: a development delivered in stages, where earlier phases have entered service and need periodic inspection. All three follow BS 7671:2018+A2:2022. C1, C2, C3, FI codes apply per the standard. New circuits added as part of the works get an EIC separately at the point they’re commissioned.

When you need this in Canterbury

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 Canterbury 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 Canterbury 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

Pricing depends on the project shape. A single-dwelling refurb EICR is priced like any domestic EICR. Multi-plot phased developments are priced per plot, with bulk rates available across plots inspected on the same visit. EIC for new circuits is a separate line, priced by circuit count. Quote responses are usually same-day on receipt of the project scope.

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 Canterbury?

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. Canterbury sites are reached from our Rochester base in around 45 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.
