The daily headaches for gas engineers, solved
The exact problems that cost gas engineers time and jobs — and how TradeHub OS fixes each one.
Paper CP12s and service records that eat your evenings.
Generate CP12 Landlord Gas Safety Records, service records and commissioning certificates from your phone, with your Gas Safe number embedded.
Landlords forgetting their annual gas safety check — and the work going elsewhere.
Automatic SMS and email reminders go to landlords and agents 30 days before every CP12 expiry, so the recurring work comes back to you.
No-heat callouts ringing out while you’re on the tools.
A missed call triggers an automatic text-back within 60 seconds, so the customer knows you’re on it before they ring the next engineer.
