Best Job Management Software for Heating & Plumbing Firms [2026]

If you run a heating or plumbing firm, the actual work is the easy bit. Everything around it eats your time: quoting, invoicing, scheduling, chasing payments, keeping customers updated, and the certificates on top of all of it.

Job management software is meant to take that off you. The right tool saves hours of admin a week, gets you paid faster and stops jobs slipping through the cracks. The wrong one becomes another thing to wrestle with at the end of a packed day.

Most of the options were built for office-based project managers, or for every trade at once. A tool that has never heard of a CP12 is not going to save you the evening.

Here’s what the best job management software for heating, plumbing and HVAC firms looks like in 2026, what each one does well, and which suits the way you work.

What to look for in job management software

Ease of use

If learning the software takes longer than it saves you, it isn’t worth it. The best app is the one you’ll actually open, rather than the one sitting unused because it’s too complicated.

Mobile-first (or better, voice-first)

You’re in a van, in a plant room, or on your back under a boiler. Whatever you pick has to work properly on a phone, ideally without needing both hands.

Certificates that work with no signal

This is what separates software built for this trade from software built for all of them. CP12s and Landlord Gas Safety Records get filled in where the boiler is, which is usually a cellar or a plant room with no bars. A certificate that needs a connection will fail you in the exact place you need it.

Quoting and invoicing

Non-negotiable. If you can’t build a quote on the spot and turn it into an invoice when the job’s done, the tool isn’t earning its keep.

Job scheduling and diary

Double-booking is embarrassing and expensive. Decent software keeps the diary straight, handles recurring jobs and makes it obvious when you’re free.

Price

Some of these charge £30 to £50+ per user per month, which adds up fast for a sole trader. Work out what you need before committing.

UK-focused

VAT handling, Making Tax Digital compatibility, Gas Safe paperwork and pricing in pounds sound boring right up until they’re missing. Software built for the US or Australian market often misses on all four.

The best job management software for heating and plumbing firms in 2026

1. Mucka

The voice-first job management app built only for heating, plumbing and HVAC

Mucka replaces dashboards, forms and dropdowns with a conversation. Send a voice note or a message the way you’d message a mate, and it creates the quote, sends the invoice, updates the diary and keeps the customer in the loop.

It’s also the only one on this list built for this industry rather than every trade at once. Gas and oil certificates come as standard and work fully offline, so a CP12 gets filled in, signed and stored in a cellar with no signal and uploads itself when you resurface. Sign one off and the next check date is set from it, so next year’s service books itself back in.

Mucka is designed around how engineers work: hands busy, phone in pocket, no time to faff with apps. It runs through WhatsApp, so there’s nothing new to learn.

The pricing starts differently to the rest. There’s a Free Forever plan, where your jobs, clients and diary stay live, you keep manual quoting and invoicing, and you get 30 typed AI replies a month. Issuing new certificates waits until you upgrade. You start on a 14-day trial with no card, and if you decide not to subscribe you drop back to Free Forever rather than losing the account. Paid plans are £29 a month for Solo and £39 per user for Team, and subcontractor seats don’t count towards the bill. Most of the tools below have no free tier once the trial ends.

Key features:

• Voice-first quoting: describe the job, get a professional quote back
• Instant invoicing by voice or message
• Job diary management
• Customer ETA updates
• Works through WhatsApp, no separate app to learn
• AI-powered: learns how you work over time
• Gas, oil and HVAC certificates (CP12, warning notices, the OFTEC forms, F-Gas leak checks) that work with no signal
• Service reminders that rebook the annual round
• Built for UK heating and plumbing firms (VAT, GBP, Gas Safe paperwork, British English)

Pricing: Free Forever plan, then £29/month Solo or £39 per user/month Team. Subbies free.

Best for: Heating, plumbing and HVAC firms, from a single van up to a full team of engineers. If you hate typing and like the idea of running the business by voice, this is the one.

Worth knowing: Mucka does not do MCS paperwork, and TM44 inspection reports need an accredited energy assessor, so it does not produce those either. If either is core to your week, that gap matters.

There’s a full breakdown on the job management software page, including what quoting and invoicing by voice looks like day to day.

2. Tradify

The established Kiwi platform popular with UK trades

Tradify has been around a while and built a solid reputation, particularly with plumbers, electricians and HVAC engineers. It came out of New Zealand and gained a strong UK following on the back of a clean interface and a decent mobile app.

It covers the core well: job tracking, quoting, invoicing, timesheets and purchase orders. Scheduling is the strongest part, with drag-and-drop calendars that hold up when you’re managing a team across several sites.

It isn’t cheap, and the interface, cleaner than some, still involves plenty of tapping and typing. Sole traders end up paying for team management features they never open.

Key features:

• Job tracking and scheduling
• Quoting and invoicing
• Timesheets and labour tracking
• Purchase orders
• Xero and QuickBooks integration
• Photo and note attachments

Pricing: From around £34/month per user (14-day free trial)

Best for: Small to medium trade businesses (2 to 10 people) who want a proven all-rounder with strong scheduling.

3. Fergus

Built by a plumber, designed for trades

Another New Zealand company, Fergus was built by a plumber fed up with the existing options, and it shows in the language, the workflow and the features. It reads like it was designed by someone who has done the work rather than watched it.

It handles quoting, job management, invoicing and scheduling, and it’s particularly good at job costing and profitability tracking. If you want to know your exact profit on each job, Fergus tells you.

The mobile app is decent rather than perfect, sometimes sluggish, and the learning curve is steeper than simpler tools. Pricing has crept up over the years, which has pushed some sole traders elsewhere.

Key features:

• Job quoting and tracking
• Real-time profitability tracking per job
• Scheduling with team calendar
• Invoicing with Xero/QuickBooks integration
• Compliance and health & safety documentation
• Material and supplier management

Pricing: From around £39/month for one user (free trial available)

Best for: Firms that want detailed job costing, especially while growing from sole trader to small team.

4. Powered Now

UK-built field service management for trades

Powered Now is one of the few field service apps built in the UK for UK firms from the start, so VAT, domestic gas certificates, electrical certificates and other UK requirements are handled natively.

It’s a solid all-rounder across quoting, invoicing, scheduling and CRM, and the forms and certificates are the standout. Part P certificates, gas safety records and similar documentation are all covered.

It can feel overwhelming at first, with a lot crammed into the mobile app and an interface that isn’t always obvious. Once you’re up and running it’s capable kit.

Key features:

• Quoting and invoicing
• Digital forms and certificates (gas, electrical, EPC)
• Job scheduling and tracking
• CRM and customer management
• GPS tracking for teams
• Works offline (syncs when you’re back online)

Pricing: From around £28/month per user (free trial available)

Best for: Gas engineers, electricians and other trades that need built-in certificate and compliance features.

5. ServiceM8

The Australian import with a clean mobile experience

ServiceM8 comes from Australia and has built a decent UK following on the strength of a genuinely good mobile app and a straightforward approach. It’s one of the cleaner-looking heating engineer apps, with a gentler learning curve than the feature-heavy platforms.

Quoting, invoicing, scheduling and customer communication are all handled well. Job dispatch is the standout for anyone managing a team, since you can see where everyone is and assign jobs as the day changes.

UK users grumble that some features feel Americanised or Australianised, and UK-specific work like Making Tax Digital arrived late. Pricing is tiered, so unlocking one feature can push you up a plan.

Key features:

• Job management and dispatch
• Quoting and invoicing
• Online booking for customers
• Automated follow-up emails and texts
• GPS tracking and route planning
• Photo and document attachments

Pricing: Free plan available, then from £25/month (Starter)

Best for: Small trade businesses wanting a clean mobile app with good dispatch, from 2 to 15 people.

6. Workever

UK-built field service management at a fair price

Workever is a newer entrant, built in the UK with field service businesses in mind and positioned as a more affordable alternative to the big names. For most heating and plumbing firms it delivers on that.

It covers job management, quoting, invoicing, scheduling and asset tracking. The interface is modern, the mobile app is designed for on-site use, and it integrates with Sage and Xero.

Being newer, it lacks the depth of an established player like Simpro, which for most small firms means everything you need without the complexity you don’t.

Key features:

• Job management and scheduling
• Quoting and invoicing
• Asset and equipment tracking
• Customer portal
• Xero and Sage integration
• Real-time team tracking

Pricing: From £29/month per user (free trial available)

Best for: Small to medium UK trade businesses wanting solid field service management without an enterprise price tag.

---

7. Onsite7

Simple, affordable job management for sole traders

Onsite7 is built for small trade businesses and sole traders who want job management without the complexity. It sticks to jobs, quotes, invoices and a diary, and does them reasonably well.

The interface is straightforward and the pricing is competitive. It won’t win design awards, and it gets the job done.

Advanced features are where it runs out. Detailed reporting, team management and accounting integrations are limited. As a step up from spreadsheets for a one-person operation, it’s a decent one.

Key features:

• Job tracking and management
• Quoting and invoicing
• Job diary and calendar
• Customer database
• Basic reporting
• Photo attachments

Pricing: From £120 per month, for up to 10 users.

Best for: Businesses wanting simple, no-frills job management at a budget-friendly price.

8. Simpro

The enterprise-grade option for bigger trade businesses

Simpro is the heavyweight of field service management. Multiple teams and complex project workflows are what it’s for, and it covers quoting, job tracking, inventory, asset tracking, fleet management and detailed financial reporting.

The price of that power is complexity. You won’t set it up in an afternoon. Most businesses need onboarding and training, and full configuration takes weeks. The pricing matches the enterprise positioning.

For sole traders and small teams it’s overkill. For an established firm running complex operations it’s a serious piece of software.

Key features:

• Full project management and job costing
• Quoting, invoicing, and purchase orders
• Inventory and asset management
• Fleet management and GPS tracking
• Advanced reporting and business intelligence
• Integrations with Xero, QuickBooks, MYOB, and more

Pricing: Hidden pricing (contact for quote)

Best for: Larger trade businesses with complex workflows needing enterprise-grade field service management.

Which one should you choose?

The right software depends on how you work and what you actually need.

Sole traders and small teams who want simple admin with no learning curve should look at Mucka. It’s the only voice-first option here, the only one with a permanent free tier, and it’s built for heating, plumbing and HVAC rather than every trade at once. The whole thing is laid out on our job management software page.

If certificates and compliance forms are the centre of your week, gas, electrical and EPC, Powered Now is the strongest on UK-specific documentation.

If you’re managing a growing team and need proper scheduling, dispatch and job tracking, Tradify and ServiceM8 both give you that at a reasonable price.

If you want to know your exact profit on every job, Fergus has the best job costing of the group.

If you’re running a larger operation with complex projects, Simpro is the only one here with genuine enterprise depth.

If you want the basics done cheaply, Onsite7 keeps it simple.

The most common mistake is buying something too complicated and then never opening it. A simple tool you use daily beats a powerful one gathering dust on your phone.

Whatever you pick, the aim is the same: less time on admin, faster payment, and your evenings back.
