The Ultimate Software Guide for Gas Engineers in 2026
Introduction. Whether you’re self-employed or run a team, the pressure on gas engineers to work faster, stay compliant, and look professional has never been greater. Paperwork slows you down, puts you at risk of errors, and makes running your business harder than it should be.
That’s where Checker comes in. In this guide, we’ll show how UK gas engineers are saving hours each week with all-in-one digital tools for certs, invoicing, scheduling and more.
Gas work is fast-paced, and compliance is non-negotiable. But paper-based systems make it hard to:
Digital job management tools like Checker solve these problems by putting everything in one place, accessible from your phone or tablet.

Here’s what today’s top engineers are using:
Checker combines all of these into one streamlined system, so you can focus on the job, not the admin.
Checker is built with UK gas engineers in mind, including integration with key certification requirements. You can use Checker alongside your Gas Safe Register obligations, just faster and smarter.
Optional: include a helpful link to https://www.gassaferegister.co.uk/ for engineers who want the regulator’s own guidance close at hand, alongside the certificates they log in Checker. You can jump straight through via the Gas Safe Register website.

Thousands of gas engineers across the UK are upgrading how they work with Checker.
The must-have list above hasn’t changed much since 2025, but the pricing and the automation on offer has moved on. Checker now runs close to 19,600 UK tradespeople and has produced 6.88 million gas compliance reports, and the platform has grown from a certificates-and-invoicing tool into something that also chases the admin for you after the job is done: an appointment reminder 24 hours before the visit, a quote chaser that follows up an unanswered quote up to three times, an invoice chaser that keeps nudging until the customer pays and then stops automatically, and an annual service reminder roughly eleven months after a customer record is created, so a finished job quietly becomes next year’s booking.
Pricing is per sub-user and published openly rather than hidden behind a sales call, split across three plans: Lite, Pro and Pro Plus, with Lite starting from £10.99 a month plus VAT. All plans are rolling, so there’s no year-long contract to sign just to get certificates and invoicing into one place. Invoices and payments also sync two-way with Xero, QuickBooks and Sage, so the books reconcile without double entry.
| Plan | Starting price | Best suited for |
|---|---|---|
| Lite | From £10.99/month + VAT per sub-user | Sole traders wanting certificates, invoicing and scheduling in one place |
| Pro | £19.99/month + VAT per sub-user | Small teams wanting the automated chasers and reminders switched on |
| Pro Plus | £25.99/month + VAT per sub-user | Growing firms wanting the full CRM and repeat-business automation |

Gas work is fast-paced, and compliance is non-negotiable. Paper-based systems make it hard to keep track of certificates and renewals, chase payments quickly, schedule jobs without double bookings, and maintain a full customer history. Digital job management tools like Checker solve these problems by putting everything in one place, accessible from a phone or tablet.
Today’s top engineers are using digital gas safety certificates, invoices and quotes sent from the job site, job scheduling with instant updates, automated service reminders via SMS or email, and a customer CRM with full history and records. Checker combines all of these into one streamlined system.
No. Checker is built with UK gas engineers in mind and works alongside Gas Safe Register obligations, making certificate and record-keeping faster and smarter rather than replacing the regulator relationship itself.
Getting started needs no tech background: start a free trial, create a first digital gas certificate, add a customer and send a test invoice, then schedule a job and set up automated reminders. Anyone on another system can get help migrating their data across.
Engineers report finishing jobs faster, fewer mistakes on paperwork, better cashflow with quicker invoicing, stronger client relationships thanks to a built-in CRM, and full compliance without a paper trail.
