Quoting and invoicing for gas engineers
SoloDesks is a quoting and invoicing app for self-employed gas and heating engineers. Invoice a service or a repair from the van before you've left the drive, quote a boiler swap with the unit, the parts and the labour itemised, and see which of last year's customers are coming due again. It's built for one engineer with a van and a Gas Safe card, not a firm with an office and a service desk.
Free plan, no card needed. £12/month for unlimited when you want it.

Why gas engineers use SoloDesks
Last November's service is this November's work
A boiler you serviced a year ago wants doing again, and a landlord's gas certificate runs out on the same date every year. That's the cheapest work you'll ever win, because they already know you and already let you in the house. Mark the job as repeating and the customer comes back up four weeks before they're due, instead of you keeping a diary two years deep and remembering to read it.
Invoice the service before you leave the drive
A service is an hour's work and a small invoice, which makes it exactly the kind that gets written up on a Sunday night, or never. Raise it on your phone at the kerb and it's numbered, sent and tracked before you've started the engine.
A boiler swap, itemised so the price makes sense
A new boiler is one intimidating number until you open it up: the unit, the flue, the filter, the controls, the labour, the making good. Itemise it and the customer can see where the money goes, and you've got a line to point at when they compare you to the quote that quietly left out the system flush.
The part you fitted at 9pm, invoiced by five past
No heat in January means you're out at night fitting a diverter valve off the van. Add the part and the callout as lines while you're still at the kitchen table, and it goes out before the customer has stopped being grateful. Gratitude is the shortest-lived thing in this trade.
Six properties for one agent, none of them forgotten
A managing agent with six rentals is six jobs on six different renewal dates, and they all come round quietly. Keep each property as its own job with its own repeat interval, so next year the work comes back to you rather than to whoever the agent happened to ring first.
Questions gas engineers ask
- What is the best invoicing app for a self-employed gas engineer?
- The one you can raise an invoice on at the customer's kerb, because a service invoice written up at the weekend is a service invoice that gets paid late. SoloDesks is built for solo gas engineers: invoice from the van, quote a boiler swap itemised down to the flue, and track which customers are due again. Free for 10 quotes and 10 invoices a month, no card required.
- Can it remind me when a boiler service is due again?
- Yes. Mark the job as repeating at whatever interval it runs on and the customer shows as due four weeks ahead of the date, so there's time to ring them and get it booked. It won't invent bookings in your calendar, because a diary full of appointments nobody agreed to is a diary you stop trusting. It just tells you who's due and leaves the decision to you.
- How do I quote a boiler installation?
- Put the boiler, the flue, the filter, the controls, the labour and the making good on separate lines, and state what isn't included, like upgrading pipework you can't see yet. A customer comparing three quotes picks the one they understand, and the itemised one is almost always it.
- Does it work for landlord gas safety work?
- It handles the paperwork side: the job, the quote, the invoice and the reminder that a property is coming up for its annual visit. The certificate itself is issued through your own Gas Safe registration and record system, exactly as it is now. SoloDesks is there so the booking and the money don't slip, not to replace anything you're registered to issue.
- How much is it?
- Free to start, with 10 quotes, 10 invoices, 10 emailed PDFs and 3 one-tap accept-links a month and unlimited clients and jobs. Pro lifts the limits, takes the SoloDesks credit line off your PDFs and chases overdue invoices for you at 7, 14 and 21 days. No contract, cancel whenever.
