Gaffer for
ventilation engineers.
Ventilation is commissioning figures and cleaning schedules. Building control wants a Part F commissioning sheet with real air balance readings on it; the insurer wants a TR19 ductwork hygiene report and a fire damper certificate that has not run out. Gaffer keeps all of them against the building, tracks the dates, and gets you back in before the damper certificate lapses. Quote, schedule, certify, invoice and get paid — with the 18 trade documents ventilation 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 ventilation engineers, your own price book and good-better-best options. Customers accept and pay a deposit from their phone.
18 trade documents ready for ventilation engineers — 11 written for this trade, 7 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.

18 trade documents, ready for ventilation engineers.
11 of them are written for this trade and 7 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.
