GASpilot puts certificates, invoicing, the diary, reminders and an AI fault-diagnosis assistant in one simple app, built for Gas Safe registered engineers and priced for one-van businesses.

The form-filling that eats your evenings happens on site instead, with most of it filled in before you start typing.
Landlord Gas Safety Records (CP12), LPG, T&P, Non-Domestic and Commercial Catering certificates. Customer details, appliances and last year's readings pre-populate automatically. You check, update and sign.
Premium. Found something unsafe? Issue a Danger Do Not Use warning notice on the spot: Immediately Dangerous or At Risk per appliance, what you isolated, what must be fixed, and the customer's acknowledgement signed on screen. Printed to the Gas Industry Unsafe Situations Procedure layout and emailed as a PDF.
Capture the customer's signature on your phone, and apply your own saved signature to new certificates automatically. The PDF lands in their inbox before you're back in the van.
Switching apps doesn't mean starting over. Export a CSV from your current app, import it in a couple of taps, and every customer comes across: names, addresses, phones, emails.
No signal in the plant room? GASpilot is offline-first. Everything works without a connection and syncs to the cloud when you're back in coverage.
Unpaid invoices are where a good month goes bad. GASpilot makes paying you the easy option.
Build invoices and quotes from your own price list, send instantly by email or text, and convert a certificate into its invoice with one tap.
Every invoice carries a secure "Pay this invoice online" button: card, Apple Pay or Google Pay. The payment appears on your dashboard automatically.
The dashboard marks every invoice red, amber or green: overdue, awaiting, paid. You see who owes you the moment you open the app, and chase with one-tap reminders.
See what you actually earn by job type and by customer, spot the work that pays best, and export everything to CSV for your accountant.
The cheapest customer to win is the one you already have. GASpilot keeps them coming back automatically.
Any job straight into the diary in seconds: services, installs, plumbing, drainage. A service job sets its own reminder for next year; a new boiler install plans five years of services automatically.
Customers get reminded by email or text before their annual inspection is due, and you approve every message before it goes. Landlords stay compliant; you stay booked.
Customers book straight into the gaps you choose in your diary: no phone tennis, no double-booking.
Every certificate, invoice, appliance and visit against the customer. Next year's CP12 starts from this year's data.
Give it the make, model and fault code. Get the most likely causes ranked, the checks in the fastest order, and the parts you'll probably need, while you're stood in front of the boiler.
Not a forum thread. A ranked list for that model and that fault code, drawing on known pattern failures.
Resistances, pressures and voltages to test against, in the order that rules causes out fastest.
Report your readings and it narrows the diagnosis. No safety lectures: it knows you're the professional.
