Digital Forms

Fill out a gas cert in two minutes on your phone, not fifteen on paper

Every certificate, job sheet, quote and invoice you’d normally write out by hand, turned into a tap-and-select form on your phone or tablet. Less typing, no missing fields, branded PDF to the customer before you’ve left the driveway.

Most engineers still carry a clipboard, a duplicate book and a biro that’s run out. You finish the job, scribble for ten minutes in the van, then post it or scan it when you get home. Half the time it never makes it back to the office. The other half it’s filed somewhere you’ll never find it again.

Checker’s digital forms replace the lot. You tap your way through the same fields you’ve been filling in for years, the form won’t let you skip anything legally required, and the finished PDF lands in the customer’s inbox the second you hit send. It’s also saved in their file forever, so when they ring you up in three years asking for a copy, you find it in two seconds.

Why it’s faster

Tap-to-select beats typing every time

Every field that’s the same on 90% of jobs is already there as a button or a dropdown. Boiler make, flue type, working pressure, ventilation result. You tap, the form fills, you move on. No spelling mistakes, no illegible handwriting, no second trip back to the customer because you forgot to write down the model number.

Why engineers switch

Four things you’ll notice in the first week

Jobs finish on site

No more “I’ll write it up tonight”. The cert is done, signed and sent before you’ve packed your tools away. Evenings back, weekends back.

You always pass an audit

Forms won’t let you submit with a legally required field blank. If Gas Safe or OFTEC come knocking, every record is in date order, indexed and ready to print.

You look the part

Customer gets a clean, branded PDF with your logo, not a smudged carbon copy. Makes a small one-van outfit look like a proper firm.

You never lose a record again

Every form is saved against the customer’s file in the cloud. Search by name, postcode or job type and find a five-year-old CP12 in seconds.

FAQ

Frequently asked questions

Are Checker’s digital certificates legally accepted?

Yes. The forms follow Gas Safe, OFTEC and BS7671 layouts, and a digital PDF signed by an engineer is accepted by landlords, letting agents, insurers and Building Control across the UK and Ireland.

Does it work without internet?

Yes. Fill the form anywhere, even with no signal. Checker saves it on your phone and syncs to the cloud automatically the moment you’re back in range.

Can the customer sign on my phone?

Yes. Hand them your phone or tablet, they sign with a finger, and the signature is locked into the PDF before it’s sent.

What if I’ve got years of paper records?

Start fresh with Checker from today. Old paper records can stay in the filing cabinet as a backup. Most engineers find their cabinet stops growing within a couple of months.

Will it work on my old phone?

Anything running iOS 14 or Android 8 onwards will run Checker without a hitch. If your phone can open WhatsApp, it can run Checker.
