Electrical installation certificate template
A site record for new electrical work that needs an Electrical Installation Certificate (EIC). Record the type and extent of the work, the supply, earthing and bonding, then each circuit with its protective device, cables, R1 + R2, insulation resistance, polarity, Zs and RCD time. The form flags failing readings, counts the circuits that pass and fail, and records the inspection, comments on the existing installation, any departures and who signed for design, construction and testing. Every question is listed below, and you can fill the live form in on this page.

When do you need an electrical installation certificate?
The notes on the IET model form say an Electrical Installation Certificate (EIC) is used for a new installation, for an addition or alteration that introduces one or more new circuits, and for replacing a consumer unit or distribution board. It records who was responsible for design, construction and inspection and testing, and is only valid with its schedule of inspections and schedules of circuit details and test results. An addition or alteration with no new circuit may go on a minor works certificate instead.

Every question in the electrical installation certificate template
A site record for new electrical work that needs an Electrical Installation Certificate: scope, supply and earthing, bonding, each new circuit with its tests, inspection items, departures and the three sign-offs. 5 sections and 65 questions. Follow-up questions and guidance appear only when an answer calls for them, so the person on site never sees the ones that do not apply.
Make it your own: every question is editable
This is a starting point, not a fixed form. Once it is in your SiteSurvey account you can reword any question, add or remove questions, sections and answer options, and add your own logo, so it fits the way your team works and the jobs you do.

- GuidanceThe checks compare readings with limits you can look up: insulation resistance with BS 7671 Table 64, Zs with the maximum you enter for each device, and RCD times with 300 ms. They help spot a reading that needs a second look. They do not replace the inspector's judgement or the certificate.

Electrical installation certificate FAQs
Who signs an EIC?
The IET model form has signatures for the design, the construction and the inspection and testing, and a person responsible for more than one signs in each place. A single-signature version is used where one person did all three. The form asks which applies and shows the right signature boxes.
Is this the certificate itself?
No. It is a site record of the work and the readings, with photos of the board. Issue the formal certificate and its schedules from your registration scheme's or your certification software.
Does the work need notifying?
In a dwelling in England, Approved Document P makes a new circuit, a consumer unit replacement, or an addition or alteration to circuits in a special location (such as around a bath or shower) notifiable. It must be certified by a registered competent person, a registered third-party certifier or building control. The form shows this when you say the work is in a dwelling.
What readings are recorded?
The supply: earthing arrangement, Ze, prospective fault current and main switch. Then for each circuit: device and rating, RCD type, conductor sizes, R1 + R2, insulation resistance with the test voltage, polarity, measured and maximum Zs and RCD operating time, with a pass or fail.
What does it warn about?
It flags an insulation resistance reading below 1 MΩ at a 500 V test, a measured Zs above the maximum you enter for the device, and an RCD time over 300 ms. A failed circuit asks what failed and what was done.
Who uses this?
Electricians and electrical contractors on rewires, consumer unit changes, extensions and new installations.
