The Best Commusoft Alternatives for UK Heating and Plumbing Firms [2026]

Commusoft is a capable platform. It has been going since 2006, and a firm running planned maintenance, SLAs and van stock across commercial contracts will use most of what it does. Firms that leave tend to leave over the deal: there’s no published price, every office user and engineer needs a licence, the standard plans run on a 12-month contract, and Commusoft says it is designed for businesses with six or more staff.

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

If you’re a larger firm on commercial contracts and want something like Commusoft with a different deal, Joblogic (from £49 per user a month, billed annually) and BigChange (quote only, now part of Simpro Group) are the closest like-for-like platforms.

If you’re an owner-run heating, plumbing or HVAC firm, Mucka (free to start, then £29 a month solo or £39 per user for a team) puts the price on the page, has no contract, includes its AI and an AI phone receptionist on every paid plan, and has a purpose-built importer for coming off Commusoft.

If certificates are most of your day, Gas Engineer Software (from £18 per user a month, billed annually) has the deepest gas and oil record set. Powered Now suits gas and electrical work, Tradify a multi-trade team, and Surefire a firm that buys through Wolseley or Plumb Center.

Why firms leave Commusoft, and when to stay

Four reasons stand out:

1. You can’t see the price without a sales conversation, and it’s per licence for office staff as well as engineers.
2. The standard plans run for twelve months, so a bad fit costs you a year.
3. Commusoft’s own demo form turns firms under six staff away, so a growing sole trader or a small team often can’t get in at all.
4. AI:den, which covers call summaries, email replies, job reports, data plate scanning and AI quoting, is sold as an add-on.

Stay on Commusoft if van stock, storeroom control, merchant invoice reconciliation and PPM contracts with SLA tracking are what your office runs on. Few of the alternatives below cover all of that.

1. Mucka: best for owner-run firms that want the price on the page

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. Nothing goes to a customer until you say so.

It covers the day a Commusoft firm is used to: scheduling, quotes with options and e-signature, invoices, gas, oil and F-Gas certificates that work with no signal, service reminders booked off each certificate’s next-check date, multi-site customers with landlords and tenants on each property, and Xero, QuickBooks, Sage and FreeAgent sync. On top of that sit an AI phone receptionist that answers in your business name and pencils jobs in for you to approve, and WhatsApp for your engineers.

Coming off Commusoft, the importer brings across customers and their properties, the appliances at each address, years of job history with notes and photos, gas certificates with the original signed PDFs, quotes, invoice history, service reminders and every photo and document. Commusoft keeps photos and documents on its own servers rather than in the backup file, and they start disappearing once the subscription lapses, so start before your renewal date.

Where it falls short: Mucka has a parts list on each job and a simple van stock count, but no storeroom control, purchase orders or merchant invoice reconciliation, and no PPM contracts with SLA tracking. 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. Joblogic: best like-for-like platform for commercial contractors

Joblogic is the closest thing to Commusoft on this list: a UK field service platform for contractors running SLAs, planned maintenance and compliance across a big customer base. It covers gas safety records, warning notices and CP12s, has F-Gas refrigerant tracking and PartsArena parts data, and sends service reminders by text and email from its desktop version. Its newer AOS AI is aimed at contract operators and bought through its sales team.

Standard is from £49 per user a month billed annually and has a free trial. Premium and Enterprise are quote only, and Joblogic says most customers sign for 24 or 36 months, so leaving Commusoft for Joblogic can mean a longer commitment than the one you left.

Price: from £49 per user a month, billed annually. VAT not stated.

3. BigChange: best for vehicle-heavy operations

BigChange leads with plumbing, heating and HVAC, handles CP12 and CP6, and has a partnership with Gas Safe. It has full fleet telematics alongside the job management. Since joining Simpro Group it sits inside a much bigger stable. Its AI agents need the paid Lightning upgrade, and it connects to Xero and Sage.

Like Commusoft, it publishes no prices and offers no self-serve trial, so the buying process will feel familiar.

Price: not published. Pricing through a demo.

4. Gas Engineer Software: best for certificate-heavy gas and oil work

Gas Engineer Software, usually called GES, is a certificate specialist, not a full field service platform. It 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 won’t replace Commusoft’s commercial tools. Invoicing and service reminders start on Core, and the AI features and Xero, QuickBooks and Sage sync are Pro-only, with the AI still in beta. There are no F-Gas records.

Price: £18 to £30 per user a month billed annually. 14-day trial, no card, no contract.

5. Powered Now: best for firms doing gas and electrical work

Powered Now is UK-built trades software with more than 80 forms and certificates, covering gas and electrical (EICRs included), plus quotes, invoices, MTD and VAT returns. The app works offline. Its PN Receptionist answers calls as an add-on from £29 a month.

It’s lighter than Commusoft on the office side, and certificates and Xero or QuickBooks sync start on the Professional plan.

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.

6. Tradify: best general job manager for a multi-trade team

Tradify is a mature job manager with timesheets, job costing and Xero, QuickBooks and Sage sync, plus purchase orders on its Plus plan. From its Pro plan it has UK gas forms: landlord and homeowner gas safety records, warning notices, boiler records and the OFTEC oil forms.

It’s built for every trade, and its gas side is thinner than Commusoft’s. There are no F-Gas or heat pump records, and service reminders and the AI tools are on the top Plus plan only.

Price: Lite £34, Pro £37, Plus £44 per user a month. VAT not stated. 14-day trial.

7. Surefire: best for firms that buy through Wolseley or Plumb Center

Surefire was built by people who ran a domestic heating firm, and it shows in the merchant link: live price checking with a Wolseley account, a Plumb Center plug-in and Parts Arena diagrams. It does CP12s and service reminders and syncs with Xero and QuickBooks.

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.

Which one should you choose?

• A larger firm on commercial contracts that wants another full platform: Joblogic, or BigChange if you run a big fleet.
• An owner-run heating, plumbing or HVAC firm that wants to see the price, skip the contract and have the AI do the chasing: Mucka.
• A firm whose day is certificates end to end: Gas Engineer Software.
• Gas and electrical work under one roof: Powered Now.
• A multi-trade team that lives on timesheets and purchase orders: Tradify.
• A firm that orders most parts through Wolseley or Plumb Center: Surefire.
