Why engineers use it

Done before you leave site

Structured fields and voice input mean the CP12 is complete the moment you pack up — no typing up tonight.

Reminders sent automatically

Landlords get renewal reminders at 8 and 4 weeks out. You get one too — so nothing falls through the cracks.

A shareable link for every job

Every completed job creates a permanent property link. Landlords see their certificate and renewal status without needing an account.

Renewals fill themselves in

Return jobs pull landlord, property, and appliance data from the last visit. Step 1 is already done when you arrive.

How it works

1

Open the wizard on site

Tap new job, pick CP12 or boiler service. Client and property details prefill from the last visit if it's a returning landlord.

2

Fill in as you work

Appliance details, readings, and safety checks are structured so you can tap through on site — no freetext, no guessing what's needed.

3

Sign and issue

Engineer and landlord sign on screen. CP12 is generated as a legally valid PDF and stored permanently.

4

Landlord gets a link

A shareable property link goes to the landlord with their certificate, next inspection date, and renewal request option when it's due.

“Used to spend an hour doing paperwork after jobs. Now the CP12 is signed and sent before I'm back in the van.”
