Gas Engineer Software: The 2026 UK Guide
What a UK gas engineer actually needs from software: the diary, Gas Safe records and certificates, VAT invoicing that gets you paid, and photo proof from the van. What to look for, and what to skip.
A UK gas engineer finishes the last boiler service of the day and still owes a service record, a landlord CP12, a quote, and two invoices, none of which is gas work and all of which keeps them at the kitchen table at nine. Gas engineer software is meant to close that gap. There are more than 120,000 Gas Safe registered engineers in the UK, most running a one-van or two-van business off a phone and a shoebox of carbon copies, and most contractor software is built for large multi-van firms with a dispatcher and priced per user accordingly.
This guide covers what a heating and gas business actually needs: a diary you run from the van, customer records with boiler history, service checklists and certificate layouts (including a landlord CP12 record) filled in on the phone, quotes and VAT invoices with a pay link and your VAT number, timestamped photo proof of the flue and the tests, and offline working for the plant room where there is no signal.
Software does not register you or replace your qualifications, it is illegal to carry out gas work unless you are on the Gas Safe Register, but it removes the paper. It also covers what to skip (dispatch boards, per-user growth tiers, setup fees) and what it should cost. KaamCam is $12 a month per user, about £9, every feature included, month to month, free trial, no card, built offline-first with native iPhone and Android apps and VAT invoicing for UK companies..
