Best Job Management Software for Gas Engineers [2026]

Gas engineers face admin challenges that general contractors don't. You're managing Gas Safe compliance records, CP12 certificate expiry dates for landlord portfolios, annual service schedules, and the legal obligation to ensure customers have up-to-date safety documentation. A generic project management tool wasn't designed for this.

The right software should handle:

• Gas Safety Record (CP12) creation and storage
• Certificate expiry tracking and automated reminders
• Boiler service history by customer and appliance
• Mobile invoicing with on-site payment collection
• Scheduling and dispatch (for businesses with multiple engineers)
• Integration with Gas Safe Register for certificate submission

Without dedicated tools, engineers typically cobble together spreadsheets, paper job sheets, and a generic invoicing app — a system that breaks down at scale and creates compliance risk.

Commusoft is one of the most widely used platforms among UK gas and plumbing engineers. It was built specifically for field service businesses including gas engineers, and has strong Gas Safe compliance features.

Key features: Digital gas certificates (CP12, commissioning certificates), appliance service history, certificate expiry reminders, customer portal, automated follow-up for annual services, invoicing, and a mobile app for engineers in the field.

Pricing: Plans start at around £79/month for a solo engineer, scaling up for teams. A free trial is available.

Best for: Gas engineers with a significant landlord or service contract portfolio who need robust compliance tracking. Commusoft's certificate management is among the best available in the UK market.

Limitations: Some users find the interface can feel complex to set up initially. Customer support quality has varied in reviews.

Jobber is a popular choice for small field service businesses globally, with a clean interface and strong mobile app. It covers quoting, scheduling, invoicing, and customer communications but lacks some gas-specific compliance features.

Key features: Online booking, automated follow-up reminders, GPS tracking for engineers, invoice automation, and a client hub for customer self-service. Integrates well with QuickBooks and Xero.

Pricing: Core plans from £35/month (solo) to £139/month (growing team). Pricing in USD — around £35–£120/month at current rates.

Best for: Gas engineers who want a polished, easy-to-use system and are willing to use a separate tool for gas certificates (such as Gas Engineer Software or Corgi HomePlan portal).

Limitations: No built-in UK gas certificate generation. Certificate management requires a separate tool or manual process.

Gas Engineer Software (GES) is a UK-focused tool built specifically for Gas Safe registered engineers. Unlike broader field service platforms, it prioritises compliance documentation and Gas Safe record-keeping.

Key features: Digital CP12 certificates, commissioning certificates, gas tightness test records, service reminder system, and a landlord portal to share certificates directly with letting agents and landlords. Works offline for use on-site.

Pricing: Starts at around £15–£25/month for a sole engineer. Very affordable for what it offers.

Best for: Sole trader gas engineers who primarily need a digital certificate solution and don't need full job management. Excellent value if certificates are your main pain point.

Limitations: Less capable as a full business management tool — weaker on quoting, scheduling, and invoicing compared to broader platforms like Commusoft or Jobber.

Tradejoy is an AI-first back-office platform for trade businesses. Unlike traditional job management tools, Tradejoy includes an AI agent that handles customer intake, sends quotes, follows up on enquiries, and manages scheduling automatically — reducing the admin burden without adding headcount.

Key features: AI-powered customer intake (text, WhatsApp, email), automated quoting and follow-up, job scheduling, invoicing with on-site payment collection, and a mobile app for engineers. Built for trade businesses including gas engineers.

Best for: Gas engineering businesses that want to reduce time spent on customer communications and admin, or that are scaling and need to handle more enquiries without more admin staff.

Limitations: No built-in gas-specific compliance features (such as CP12 certificate generation) in 2026 — best used alongside a dedicated certificate tool like Gas Engineer Software or Commusoft's compliance features.

There's no single best tool for all gas engineers — the right choice depends on your business size and primary pain points:

• Sole trader, mainly certificates and services: Gas Engineer Software at £15–£25/month is hard to beat for the core compliance use case
• Small business with a growing customer base: Commusoft gives you comprehensive compliance features plus job management as you scale
• Business prioritising customer experience and automation: Tradejoy's AI layer handles the customer communication overhead that grows as the business does
• Engineer who needs clean invoicing and wants to add gas cert software separately: Jobber plus Gas Engineer Software is a well-regarded combination among UK engineers

Before committing, take advantage of free trials. Most platforms offer 14–30 days free. Test the mobile app (you'll use it on-site daily), the invoice generation speed, and the certificate workflow before deciding.
