Time saved is money earned.
Designed around the Gas Safe caravan inspection record format, built for the realities of field work.
Fill in digital caravan gas safety inspection records on your phone or tablet. Generate a print-ready PDF in one tap. No printer, no paperwork, no faff.
No signal on site? No problem. Certii works fully offline as an installable PWA and syncs automatically when you're back online.
Certificates save straight to your Google Drive, not our servers. Your data stays in your account, completely private, completely yours.
Save your regular caravan parks and sites for quick selection. Park details auto-fill so you spend less time typing and more time working.
Save your most common appliances. Make, model, flue type and analyser readings auto-fill when you type a name. Synced to Google Drive.
Add multiple engineers with individual Gas Safe licence numbers and digital signatures. Switch between engineers per certificate with a single tap.
No training required. If you can fill in a paper certificate, you can use Certii.
Enter your Gas Safe registration, company details, and engineer information. Pre-fills every certificate automatically from then on.
Open the app, select your park, and complete the inspection form. Appliances, alarms, tests, and faults. All on one screen.
