Looking for a ServiceM8 alternative?

ServiceM8 is built for every trade. I’m built for heating.

I'm Mucka: an AI that runs your heating and plumbing firm. ServiceM8 has a lovely app and, fair play, its new Office Agent flags work and prepares actions for your approval much as I do. I’m built for UK heating, plumbing and HVAC, though, with the certificates, WhatsApp and phone answering that work runs on.

The short version

Being straight about ServiceM8

The quick answer. ServiceM8 suits field teams in any trade that want a polished app, online booking and a big add-on marketplace, priced by job volume with unlimited users, from free (one user, 30 jobs) to £269 a month. Its Office Agent flags work and prepares actions for approval. Mucka suits UK heating, plumbing and HVAC firms that want the same approve-it-in-one-tap AI built around gas, oil and F-Gas certificates and service reminders, plus WhatsApp and a live AI phone receptionist, with no job caps: free to start, then £29 solo or £39 per user, ex VAT.

ServiceM8 is a clean, capable job manager with a genuine free plan, online booking, GPS and a big add-on marketplace. It charges by job volume with unlimited users, which suits bigger field teams. Its Office Agent is a real step: it flags outstanding quotes and overdue invoices and prepares actions for your approval, with scheduled checks on the Pro add-on. But it’s Australian and light on UK compliance, and busy sole traders hit its job caps fast.

We both have a free plan and both prepare work for your approval. I’m UK-built for gas, oil and F-Gas certificates, MTD, CIS and VAT reverse charge, you can talk to me on the phone or on WhatsApp, my receptionist is answering calls today, and there are no job caps.

Why firms come to me

Three reasons they make the switch

My engine knows your certificates

ServiceM8’s Office Agent and I both line up work for your approval. Mine starts from what a heating firm owes: the landlord check falling due, the new boiler that needs registering inside 30 days, the job still missing its certificate. ServiceM8’s certificates are generic forms, so none of that is built in.

Built for the UK

I have Gas Safety Certificates, MTD, CIS and VAT reverse charge built in, and no cap on how many jobs you run. ServiceM8 is Australian software with generic forms.

Talk to me, or use WhatsApp

You can talk to me in the app or on the phone, and your crew can reply on WhatsApp, so there’s no new app for your engineers to learn. ServiceM8 has no WhatsApp, and its phone agent is still rolling out from a waitlist.

So, which one

Be honest with yourself

Choose ServiceM8 if…

  • You want a big third-party add-on marketplace
  • You run a large field team and prefer unlimited-user, job-volume pricing
  • UK-specific compliance and certificates aren’t central to your work

Come to me if…

  • You want an AI that knows gas, oil and F-Gas paperwork as well as quotes and invoices
  • You want UK compliance built in: gas certs, MTD, CIS, VAT reverse charge
  • You want to talk to me or reply on WhatsApp, with no job caps
  • You want a free plan and free subbie seats
