GasPass FREE TEST VERSION
Gas paperwork done on site, on your phone.
GasPass is a free app for UK gas and heating engineers. Records, jobs, quotes, invoices and calculators — everything kept on your phone, with no account and no subscription.
Built by a working gas engineer. Still being tested — see what that means.
This is a test version. Some calculations, rules or certificate wording may be wrong or out of date. You are responsible for checking every result and record against the current standards and the manufacturer's instructions before you rely on it. Read the terms.
What it does
Gas records
Landlord gas safety records, service records, warning notices, commercial and unvented cylinder records — finished as clean PDFs on site.
Jobs, quotes & invoices
Customers, properties and appliances in one place. Quotes and invoices with VAT and CIS, emailed from your phone.
Calculators
Gas rate, pipe sizing, ventilation, tightness testing and an unsafe situations guide — with results you can send straight into a record.
Renewals & reminders
Know which records are coming due, and get a reminder before each job.
Flue gas analyser EXPERIMENTAL
Read combustion results over Bluetooth. Works with the testo 330-2 LL for now; more analysers to come.

No account, no server, no tracking. Everything lives on your phone, with password-protected backups.
