Gaffer for
solar thermal installers.
Solar thermal is a small install with a long tail: the glycol degrades, the pump station needs looking at, and the system quietly stops paying for itself if nobody services it. Gaffer records the solar fluid and glycol charge at commissioning, keeps the MCS certificate against the property, and books the annual service before the customer notices the cylinder has gone cold. Quote, schedule, certify, invoice and get paid — with the 12 trade documents solar thermal installers 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 solar thermal installers, your own price book and good-better-best options. Customers accept and pay a deposit from their phone.
12 trade documents ready for solar thermal installers — 8 written for this trade, 4 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.
