Smaller domestic consumer unit with each circuit clearly labelled

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 Istead Rise 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

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 Istead Rise

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

The deliverable is a standard three-part EICR PDF — form, schedule of inspection, schedule of test results — plus, where relevant, a project cover note explaining how the EICR relates to the wider build documentation. On a refurbishment with both retained and new wiring, the EICR covers the retained sections and an EIC (or set of EICs) covers the new circuits. Findings are coded C1/C2/C3/FI. Unsatisfactory results need remedying within 28 days under BS 7671 best practice; on developer work we typically coordinate the remedials with the wider project programme.

Why book CJA Electrical for your Istead Rise 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 Gravesham projects. Reports back within 48 hours of testing; remedial quotes attached where needed.

How the inspection runs

The developer flow: Initial conversation about the project — what’s existing, what’s new, where on the programme the inspection sits. Quote and appointment options out the same day. Inspection coordinated with the site lead. Report PDF inside 48 hours. EIC for new circuits issued separately as work is commissioned. Remedial work, if needed, scoped and quoted to fit the wider build cost.

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. Get in touch with the project scope and we’ll come back with a fixed quote.

FAQs

Do new builds in Istead Rise 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.

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 Istead Rise?

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. Istead Rise sites are reached from our Rochester base in around 28 minutes.
