HOW GES COMPARES
Full job management, built specifically for heating & plumbing businesses
A certificate app helps you handle your digital records, but then falls short. Enterprise field service management software is feature-rich, but not made for the heating trade. GES offers the best of both worlds.
Basic certificate apps
Cheap, digital records & certificates- Gas certificates
- Basic quotes & invoices
- Partly automated reminder emails
- No payments on site
- No fully streamlined job management
- Weaker team scheduling, built around engineers
Works well as a cert pad if you're doing a few jobs a month, but falls short for managing a busy business.
The platform that runs the whole business - Built for gas, heating, and plumbing businesses
- Every UK gas industry certificate
- Full job management, from quote → final payment
- Reminders that fill your schedule & chase payments
- Team scheduling & permissions
- Customer, property & appliance history
- Helps admin staff & engineers
- Live in minutes — no complex setup and free 1-1 onboarding
Around half the price of enterprise software and built only for your trade.
General field-service software
Powerful, but not made for heating jobs.- Feature-rich, excels for multi-trade businesses
- Forms often add-on or custom
- Complex setup that can take months and require paid training
- Built around office teams
- Significantly more expensive, as you're funding features for other trades too
- Support not focused on UK heating trade
Gas-configured, not gas-native. Roughly double the cost for a typical heating business.
REPEAT WORK, ON AUTOPILOT

Stop chasing work. Gas Engineer Software keeps next year's jobs booking themselves while you're out on the tools.
