## What is Circuitbook?

Circuitbook lets a UK electrician fill in, sign and send electrical certificates from the phone in their pocket, before leaving site.

Your certificates are yours: stored on your phone, backed up to a file you control, and exportable any time. Move to a new phone by restoring that backup file. Stop paying and you can still open, print and export every certificate you have ever made.

CERTIFICATES
- Electrical Installation Condition Report (EICR), for landlord, house sale and periodic inspections.
- Minor Electrical Installation Works Certificate, for additions and alterations that do not add a circuit.
- Electrical Installation Certificate (EIC), for new work and alterations.
- Built for BS 7671:2018+A4:2026 from day one. The declaration reads BS 7671 2026.

BUILT TO BE FAST ON SITE
- One screen per circuit, and swipe to the next.
- Copy the previous circuit in one tap. Copy a whole board for identical flats. Copy a whole certificate to a new address.
- Inspection schedule items default to a tick, so you only change the exceptions.
- Observations with C1, C2, C3 and FI codes, wording, location and up to four photos each.
- The overall outcome is worked out from your observation codes. You cannot contradict it without writing an override note.
- Missing fields are listed with a jump link before you sign.

AMENDMENT 4 RULES BUILT IN
- Protective neutral bonding (PNB) as an earthing arrangement.
- Minor works end-to-end readings recorded as r1-r1, rn-rn and r2-r2.
- The edition is stored on every certificate, so old certificates always print as they were issued.

TEST DETAILS
Continuity, insulation resistance, polarity, Zs, RCD operating times, and RCD and AFDD test buttons. Record your instruments and get a warning when calibration is out of date.

SIGN, PREVIEW AND SEND
Draw your signature on screen, preview the PDF, then send it by email, WhatsApp, Files or any share sheet app. Issued certificates are frozen. A correction creates a new certificate that refers to the old one.

CLIENTS AND PROPERTIES
Every certificate for a property sits in one place with the next inspection date. Find an old one by address or client in two taps.

YOUR CERTIFICATES ARE YOURS
- Works fully offline. Entry, signatures, photos and PDFs need no signal.
- Everything is stored on your phone. There is no account to create and nothing is sent to us.
- A backup file you control, and a free "export everything" that gives you the PDFs by property and a spreadsheet of certificates. Keep the backup in iCloud Drive or anywhere you choose, and restore it on a new phone.
- A lapsed subscription never locks the past. You can still open, print, share, back up and export everything you have made.
