Best Job Management App for HVAC Contractors UK 2026: PPM Scheduling, F-Gas Records and Simpro vs Tradify

Written by Tom Ellis · Senior Trades Editor

Last updated: July 2026

Quick Answer

Sleepless Tradesman's free tier covers HVAC job management with AI-generated job cards, PPM scheduling and CIS deductions at zero monthly cost. Tradify at £29/user/month suits HVAC businesses with multiple engineers, with recurring contract scheduling and purchase orders. Simpro is the enterprise choice for commercial HVAC contractors needing full F-Gas records, complex PPM schedules and multi-site asset management.

Running an HVAC contracting business in the UK means juggling a lot more than just fitting boilers and servicing air conditioning units. You are managing HVAC work orders across multiple sites, tracking F-Gas certificate numbers, scheduling annual boiler service reminders, handling PPM (planned preventative maintenance) contracts, and chasing invoices — often all from the back of a van. Generic small-business software was not built for any of that. It does not understand service contracts, it cannot log refrigerant handling for F-Gas compliance, and it has no concept of a heating engineer CRM that ties a customer's full service history to a single property record.

The right job management app for an HVAC contractor makes the difference between spending an hour on admin every evening and closing the laptop by five. In 2026 the market has matured significantly, but most tools still fall short for UK-specific requirements: Making Tax Digital VAT submissions, CIS deductions for subcontractors, and the kind of maintenance scheduling depth that commercial heating engineers need. We have tested the five most-discussed platforms among UK HVAC contractors and laid out exactly what each one does well — and where it falls short.

Whether you are a sole-trader gas engineer working domestic boiler services or a team of five covering commercial air conditioning maintenance contracts, there is a clear best choice for your situation. Here is the full comparison.

What HVAC Contractors Need in Job Management App Software

Most job management apps are built for general trades or, worse, for US-market contractors where VAT, CIS, and F-Gas obligations simply do not exist. Before comparing platforms, it is worth being clear on what HVAC-specific requirements actually matter:

  • ✓HVAC work orders with equipment records. Each job should be linkable to a specific asset — boiler make/model, refrigerant type, system capacity — so engineers arrive with context rather than starting from scratch every visit.
  • ✓Service contracts and recurring maintenance scheduling. PPM scheduling for commercial clients needs to auto-generate jobs at the right intervals (quarterly, biannual, annual) without manual intervention. A boiler service tracker that sends automatic reminders to domestic customers is equally valuable.
  • ✓F-Gas log and compliance tracking. UK F-Gas regulations require records of refrigerant additions, removals, and leak checks for any system containing more than 5 tonnes CO2 equivalent. A job management app that cannot capture this means maintaining a separate spreadsheet — which is exactly the kind of double-handling that costs time.
  • ✓Heating engineer CRM with full property history. A good heating engineer CRM links every job, every certificate, and every part used to both the customer and the property. When a customer calls about a fault on a boiler you serviced two years ago, you need that history in seconds.
  • ✓UK VAT and CIS compliance. Making Tax Digital VAT submissions, CIS deduction tracking for subcontractors, and VAT-inclusive/exclusive quoting are non-negotiable for most UK HVAC businesses. Platforms built for the US market handle none of this natively.
  • ✓Mobile-first job cards with offline capability. HVAC engineers are rarely at a desk. The app needs to work reliably on-site, capture photos of equipment and completed work, collect customer signatures, and sync when connectivity returns — without losing data.

1. Sleepless Tradesman — Best Free Option for UK HVAC Contractors

Sleepless Tradesman was built from the ground up for UK tradespeople, which means it actually understands what an HVAC contractor's working day looks like. The AI-powered job creation lets you describe a job in plain English — "annual boiler service at 14 Maple Road, customer wants a reminder next October" — and the app structures it correctly, assigns the right job type, and sets a follow-up date automatically. That alone saves meaningful time across a week of bookings.

Ratings methodology: Based on hands-on testing against real UK tradesperson workflows, reviewed August 2026. Disclosure: Sleepless Tradesman is our own product — treat that row with appropriate scepticism; competitor ratings reflect direct platform testing.

The free tier has no time limit and no job cap for sole traders, covering AI job management, invoice sending, customer records, and job tracking. UK VAT handling and CIS deduction support are built in natively. For HVAC contractors, the customer and property history view functions as a practical heating engineer CRM — every job, note, and invoice for a given address is visible in one place, making return visits and service contract renewals much faster to handle.

Pros for HVAC contractors: Free tier with no expiry, UK VAT and CIS built in, AI-powered job creation, property-level history, no per-user pricing on entry tier, designed specifically for UK tradespeople.

Cons: F-Gas log capture and PPM scheduling automation are more limited compared to enterprise field-service platforms. Less suited for large teams needing complex multi-engineer dispatch boards.

2. Tradify — Best Paid Option for UK Tradespeople

Tradify is the most popular dedicated trade app among UK contractors and for good reason. At £29 per user per month it sits at a reasonable price point for a team, and the feature set is genuinely well-suited to HVAC businesses: job scheduling, quoting, purchase orders, timesheets, and invoicing are all present and well-executed. The job management interface is clean and works well on mobile, which matters when your engineers are updating job status from customer premises.

For HVAC contractors running service contracts, Tradify's recurring job functionality lets you set up maintenance schedules that auto-generate work orders at defined intervals — useful for PPM scheduling on commercial accounts. Integration with Xero and QuickBooks means the invoicing side connects cleanly to your accounting setup.

Pros for HVAC contractors: Strong UK market focus, recurring job scheduling for PPM contracts, clean mobile interface, good quoting tools, Xero integration, active UK customer support.

Cons: No free tier beyond the 14-day trial — costs add up quickly per user for larger teams. F-Gas compliance logging requires workarounds using custom fields. Not ideal for sole traders who want a no-cost solution.

3. ServiceM8 — Best for Field Service Dispatch

ServiceM8 is the platform of choice for HVAC businesses that operate a fleet of vans and need a real-time dispatch board. The map-based scheduling interface lets office staff see every engineer's location and drag-and-drop jobs to the nearest available technician — a genuinely useful capability for reactive breakdown cover or commercial HVAC maintenance rosters. The iOS app is polished and engineers can complete job cards, capture photos, and collect signatures fully offline.

The free plan covers up to 20 jobs per month, which is sufficient for testing but not for a live business. ServiceM8 was built primarily for the Australian market and some UK-specific requirements — particularly CIS deductions — are not natively supported. VAT handling works but requires configuration. For UK HVAC contractors the platform is functional but not optimised.

Pros for HVAC contractors: Excellent GPS-based dispatch board, strong iOS mobile app, offline job cards with photos and signatures, asset management for equipment records, email/SMS automation.

Cons: Australian-first platform — CIS not supported natively, some UK tax configuration needed. Pricing scales with job volume rather than users, which can become expensive for high-volume businesses. Less suited to sole traders.

4. Jobber — Best for Client Communication

Jobber's strongest selling point is its client-facing experience. The customer portal, automated job reminders, follow-up review requests, and two-way SMS communication are all genuinely polished — if your HVAC business competes partly on professionalism and customer experience, Jobber makes it easy to deliver that consistently. Automated appointment reminders alone reduce no-shows meaningfully for domestic heating engineers.

The limitation for UK HVAC contractors is that Jobber is a US-first product. VAT is supported but CIS is not, and the pricing — starting at around £49/month — puts it at the expensive end for what is effectively a job management and CRM tool rather than a full trade management platform. The boiler service tracker and maintenance scheduling features work but lack the HVAC-specific depth that trade-focused UK platforms offer.

Pros for HVAC contractors: Best-in-class client portal and communication tools, automated review requests, polished quoting and invoicing, strong mobile app, good reporting.

Cons: No CIS support, US-first product, starts at £49/month which is expensive relative to UK alternatives, no meaningful free tier. Less suited to contractors who need F-Gas logging or complex PPM scheduling.

5. Simpro — Best for Commercial HVAC & PPM Contractors

Simpro is the enterprise-grade choice for commercial HVAC contractors running complex PPM contracts across multiple sites. It is the only platform on this list with a dedicated F-Gas log module, allowing engineers to record refrigerant type, quantity added or removed, and leak check dates against specific assets — meeting UK F-Gas Regulation requirements without a separate spreadsheet. PPM scheduling auto-generates work orders at the correct intervals and links each visit to the relevant contract and asset record.

Simpro handles UK CIS deductions natively and supports domestic reverse charge VAT for construction-related HVAC work. The asset management module is particularly strong — every piece of equipment on a client site has its own record, service history, and compliance status. For a commercial HVAC business managing air handling units, chillers, and VRF systems across dozens of commercial properties, this level of asset and contract management depth is essential.

Pros for HVAC contractors: Dedicated F-Gas log module, full PPM contract management, multi-site asset records, native CIS and domestic reverse charge support, enterprise-grade reporting for commercial accounts.

Cons: No free plan — pricing is enterprise-level and requires a demo for a quote. Significant setup and onboarding time. Overkill for sole-trader gas engineers or small residential HVAC businesses. Best suited to contractors with five or more engineers and multiple commercial PPM contracts.

Which App Is Right for Your HVAC Contractors Business?

Solo HVAC contractor or sole-trader gas engineer: Sleepless Tradesman is the clear choice. The free tier covers everything a one-person HVAC business needs — job creation, invoicing, customer history, and UK VAT handling — with no monthly subscription eating into your margin. The AI-powered job management is particularly useful when you are taking bookings while on-site and need to capture job details quickly without typing everything out manually.

Team of 2–5 HVAC engineers with service contracts:Tradify is the best paid option for this scenario. The recurring job functionality handles PPM scheduling well, the per-user pricing is predictable, and the UK-focused design means VAT and CIS work without workarounds. If your team is growing and you need schedulable maintenance contracts as a core workflow, Tradify's feature set justifies the subscription cost.

Accounting is your priority: If you are already on QuickBooks and your main pain point is tax compliance rather than job scheduling, stay on QuickBooks and add Sleepless Tradesman or Tradify for the operational side. The QuickBooks + Tradify combination is used by a significant number of UK heating and cooling businesses for exactly this reason — accounting accuracy without sacrificing field management capability.

Commercial HVAC business with multiple vans and reactive callouts:ServiceM8's GPS dispatch board becomes genuinely valuable at this scale. If you have four or more engineers responding to commercial breakdown calls and need real-time location visibility to assign the nearest available technician, ServiceM8's map-based scheduling is the best in class. Budget for some setup time to configure UK VAT correctly and accept that CIS will need a separate accounting tool.

Commercial HVAC contractor with F-Gas obligations and complex PPM contracts:Simpro is the only platform built for this level of HVAC operational complexity. If you are managing dozens of commercial sites, need a compliant F-Gas log integrated into your job management, and run structured PPM schedules with multi-asset records, Simpro's enterprise feature set justifies the investment. It is not suitable for smaller businesses, but for commercial HVAC contractors it is the clear specialist choice.
