RCD and loop impedance testing in progress on a domestic circuit

Developer compliance for electrical work splits into two streams. New installations — circuits added during build, refurb, or conversion — produce an Electrical Installation Certificate (EIC) at commissioning. Existing installations being inspected periodically produce an EICR. We work with Sheerness developers on both: EIC for new work signed off as it goes in, EICR on existing installations inherited through purchase or returned to service after refurb.

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 Sheerness

Developers come to us for EICR work in a handful of recurring patterns: pre-purchase due diligence on properties being acquired for refurb; snagging-stage inspection where an existing installation has been kept and needs final sign-off; periodic inspection on the early phases of a multi-phase development that have entered service; and change-of-use work where an existing installation needs assessment before being adapted to new use. The trigger varies; the inspection itself is consistent.

What the report contains

Reports come back as the standard EICR PDF — form, schedule of inspection, schedule of test results, all in one document. For developer projects we can supply alongside a covering memo summarising the inspection scope, what was in EICR scope vs EIC scope, and any limitations encountered. Failed findings come with remedial quotes for the developer to incorporate into the project cost. Re-test on completion to issue a clean certificate.

Why book CJA Electrical for your Sheerness EICR

What developers usually want from an EICR partner is precision and timing. Precision because the EIC vs EICR distinction matters and gets it wrong on BC sign-off. Timing because the inspection slot has to fit a wider project programme, often with multiple trades on site. City & Guilds 2391 qualified for the inspection and testing, ten years on Swale domestic projects, comfortable working alongside other trades on a live site. Same-week turnaround typical for Sheerness projects.

How the inspection runs

What it looks like on a typical Sheerness refurb: Site visit to scope the existing installation. Pre-refurb EICR if the developer wants the starting condition on file. Refurb proceeds. New circuits (where any are added) get an EIC at commissioning. Post-refurb EICR confirms the kept-and-adapted installation is still satisfactory. Final paperwork pack handed over with the project sign-off.

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

What about Building Regulations notification on new circuits?

New circuits in dwellings are notifiable work under Building Regulations in England. We issue the appropriate Electrical Installation Certificate (EIC) at commissioning and the developer’s Building Control body takes the notification through standard channels. We don’t act as a self-certification scheme but the EIC documentation is what the BC body needs to sign off the work.

Can you inspect occupied phases of a phased development?

Yes. Where earlier phases have entered service and tenants or buyers are in residence, we coordinate access through the site management team or directly with residents. The inspection itself is the standard EICR — same scope, same format. Periodic inspection on occupied phases is the most common scenario.

Do new builds in Sheerness need an EICR or an EIC?

New builds need an Electrical Installation Certificate (EIC), not an EICR. The EIC is issued by the installing electrician at the point the new installation is commissioned and forms part of the Building Control sign-off documentation. An EICR is a periodic inspection document that applies to existing installations after they’ve entered service — typically five years or more after the EIC was issued.

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.
