Tradify is a good job manager. It has proper team tools, with timesheets and job costing on every plan and purchase orders on Plus, and it syncs with Xero, QuickBooks and Sage. Heating and plumbing firms outgrow it in a few specific places: it’s built for every trade, so gas forms start on the Pro plan, service reminders are Plus-only, there are no F-Gas or heat pump records, and every user costs £34 to £44 a month.
We make one of the alternatives below, so read our section with that in mind. Each section, ours included, says where that product falls short. Every price comes from the provider’s own website, checked in late October 2026, and excludes VAT unless the provider doesn’t say.
The quick answer
For a heating, plumbing or HVAC firm, Mucka (free to start, then £29 a month solo or £39 per user for a team) has gas, oil and F-Gas certificates and service reminders on every paid plan, an AI that chases quotes and flags slipping jobs for one-tap approval, and an importer built for Tradify.
Fergus (£39 to £45 per user) is the closest match if job costing is why you chose Tradify. Gas Engineer Software (from £18 per user, billed annually) is the certificate specialist, Powered Now covers gas and electrical certificates, ServiceM8 has a free plan and prices by job volume, and Surefire links to Wolseley and Plumb Center pricing.
Why heating firms leave Tradify, and when to stay
The usual reasons are the gas side and the bill. A firm doing landlord checks needs the CP12 and the reminder that brings next year’s visit back, and on Tradify those mean Pro for the forms and Plus for the reminders. An HVAC engineer will find no F-Gas records at all. And at £34 to £44 a head, the bill climbs with every engineer you add.
Stay on Tradify if you run a multi-trade team that lives on timesheets and purchase orders. It’s more mature there than most of this list, ours included.

1. Mucka: best for heating, plumbing and HVAC firms
This one is ours. Mucka is job management for heating, plumbing and HVAC firms, built around an AI engine that watches your jobs, engineers, diary and money and drafts whatever needs doing for you to approve with one tap. When a quote goes quiet or a job is about to slip, it puts the fix in front of you, where Tradify waits for someone to notice.
The certificates cover the CP12, warning notice, service and breakdown records, LPG and non-domestic records, all five OFTEC oil forms, five F-Gas records, heat pump records and Legionella, and they work with no signal. Each certificate’s next-check date goes into your service reminders, on every paid plan. Your engineers can update jobs from WhatsApp, and an AI phone receptionist answers in your business name and pencils jobs in for you to approve. Accounts sync covers Xero, QuickBooks, Sage and FreeAgent.
The Tradify importer brings the whole customer book and every site each customer owns, so a landlord with eleven flats arrives as a landlord with eleven flats, plus invoices with their lines and what’s still owed. Tradify’s own export leaves out certificates, service reminders and job notes, so ask Tradify for those before you cancel.
Where it falls short: Mucka’s timesheets are newer than Tradify’s and it has no purchase orders. Certificates aren’t on the free plan.
Price: free plan for quotes and invoices; £29 a month for a solo owner, £39 per user for a team, apprentices £19, subcontractors free. 14-day free trial of everything, no card, no contract.
2. Fergus: best for job costing
Fergus is built around job costing. Its financial dashboard shows live cost against quote and where your margin is going, and it has timesheets and purchase orders, so a Tradify team won’t lose its tools. Fergus AI answers questions about jobs and numbers and drafts messages, quotes and invoices when you ask.
It’s New Zealand software with certificate templates rather than a UK gas record set, and it connects to Xero, QuickBooks and MYOB, with no Sage or FreeAgent.
Price: Essentials £39, Professional £45 per user a month. In October 2026 it was running a 90% off offer until December. 14-day trial.
3. Powered Now: best for gas and electrical certificates together
Powered Now is UK-built, with more than 80 forms and certificates covering gas and electrical (EICRs included), plus quotes, invoices, MTD and VAT returns. The app works offline, and customers are reminded a month before a certificate expires. Its PN Receptionist answers calls as an add-on from £29 a month.
Certificates and Xero or QuickBooks sync start on Professional. There’s no Sage or FreeAgent sync.
Price: Business £280 a year for one user (no certificates), Professional £320 per user a year, Premium £400 per user a year, plus VAT. 14-day trial, no card.
4. ServiceM8: best free plan for a general trades app
ServiceM8 has a polished app, online booking, a big add-on marketplace and a free plan. It prices by job volume with unlimited users on paid plans, which suits a big field team. Its Office Agent flags outstanding quotes and overdue invoices and prepares actions for your approval.
It’s Australian software with generic forms rather than UK gas records, and a busy sole trader soon hits the job caps. For a heating firm it solves Tradify’s per-user cost but not its gas gaps.
Price: Free (one user, 30 jobs a month), Starter £25, Growing £59, Premium £119, Premium Plus £269 a month.
5. Gas Engineer Software: best for certificate-heavy gas and oil work
Gas Engineer Software has 20 record types covering domestic and non-domestic gas, LPG, catering, the OFTEC oil forms, a heat pump service record, Legionella and unvented cylinders, Bluetooth readings from Kane, Anton and TPI analysers, more than 2,300 boiler manuals and full offline working.
It’s a certificate app first, so a Tradify team will find less on the job management side. Invoicing and service reminders start on Core, the AI features and accounts sync are Pro-only, and there are no F-Gas records.
Price: £18 to £30 per user a month billed annually. 14-day trial, no card, no contract.
6. Surefire: best for firms that buy through Wolseley or Plumb Center
Surefire was built by people who ran a domestic heating firm. It has live price checking with a Wolseley account, a Plumb Center plug-in and Parts Arena diagrams, plus CP12s and service reminders, with Xero and QuickBooks sync.
Its site makes no mention of AI, voice or a phone receptionist. There’s a two-user minimum and the free trial starts with a phone call to its office.
Price: £35, £45 or £60 per user a month, minimum two users, no contract period.
