Paper vs app: an honest look at going digital for CP12s

A digital gas safety certificate is just as legally valid as a paper one: Gas Safe Register accepts electronic records, and what makes a CP12 valid is the check and the engineer's registration, not the medium. So going digital isn't about compliance; it's about whether it saves you enough time to be worth the change.

The validity question, settled

The worry that stops a lot of engineers is whether a record typed on a phone counts. It does. The Landlord Gas Safety Record can be produced, stored and sent electronically, and a PDF emailed to a landlord is as valid as a carbon-copy pad. Keep it for the required two years, get the tenant their copy, and the format is your choice.

What going digital actually changes

• You write the record once, on site, instead of scribbling on a pad and typing it up at home that evening.
• Delivery is instant: the landlord and tenant get their copy by secure link or PDF before you've left the drive, so the 28-day duty is handled on the spot.
• Last year's job is there when you walk back in: appliances, photos and the previous record, instead of hunting through a filing cabinet.
• Renewals can chase themselves, because the next-due date is recorded rather than remembered.

What it doesn't change

It doesn't change the check. You still do the same work to the same standard; the app just handles the writing-up and the filing. And it doesn't make you compliant on its own: no software can issue a valid record without a Gas Safe registered engineer doing an in-person check. Anyone selling automatic certificates is selling something you shouldn't buy.

Is it worth it?

If you do a handful of records a year, a pad is fine. The case for going digital grows with volume: the evening paperwork, the resend-that-certificate calls, and the renewals you didn't know were due are what a system removes. The honest answer is that it's worth it when the admin has started to cost you real time or real work, and not before.
