Gaffer for
gas engineers.
Gas work is a compliance business with a boiler attached. Landlord CP12s expire every twelve months without fail, and the engineer who reminds the landlord first keeps the contract. Gaffer issues the certificate on the phone, files it against the property, and puts next year’s renewal in the diary the moment this year’s is signed. Quote, schedule, certify, invoice and get paid — with the 24 trade documents gas engineers actually use already in the account.
Where two names look alike they are different documents — a notification is not the certificate that follows it, and two schemes covering the same work each want their own form. If you think one is missing, or that one of these is redundant, say so and we will change the pack.


Priced quote templates for gas engineers, your own price book and good-better-best options. Customers accept and pay a deposit from their phone.
24 trade documents ready for gas engineers — 18 written for this trade, 6 shared with others — filled in on the phone, signed on site and emailed as a PDF before you leave.
One tap raises the invoice from the accepted quote, nets off the deposit and sends a Pay Now link. Reminders chase for you.
Certificates and services with an expiry date become next year’s work. Gaffer texts the customer a booking link before it lapses.
A landlord gas safety check, end to end

24 trade documents, ready for gas engineers.
18 of them are written for this trade and 6 are shared with others — an EICR is an EICR whoever issues it. Every one is a real digital form, not a blank template.
Each one is a proper digital form: the fields that document actually needs, signature capture, photo attachments, a PDF the customer can keep, and — where it has one — an expiry date Gaffer tracks. Completed on the phone, offline if it has to be.
