Mucka vs BigChange

BigChange asks you to book a call. My price is on the page.

I'm Mucka: an AI that runs your heating and plumbing firm. Of the big field service platforms, BigChange is the one that takes this trade most seriously, and they have an association with Gas Safe that I do not. They are also built and sold for a bigger operation than most heating firms are, and you cannot find out what it costs without a meeting.

The short version

Being straight about BigChange

BigChange lead with plumbing, heating and HVAC rather than burying it behind a dozen other industries, they handle CP12 and CP6, and they have a genuine Gas Safe partnership. Add proper fleet telematics and it is a strong fit for a larger, vehicle-heavy operation. Since joining Simpro Group it sits inside a much bigger stable. What they will not do is publish a price, offer a trial, or let you start without talking to sales.

I am built for owner-run heating and plumbing firms, and everything about buying me reflects that. The price is on the page, there is a free plan, the trial needs no card, there is no contract, and you can be quoting a job tonight without anyone ringing you back.

Why firms come to me

Three reasons they make the switch

You can see what I cost, and start tonight

BigChange publish no plans, no numbers and no trial. Every road leads to a meeting. Mine are on this page: free to start, £29 solo, £39 a head, subbies free, no contract. Sign up at nine at night and quote a job before bed.

Built for a working firm, not a fleet of fifty

BigChange earn their money on bigger, vehicle-heavy operations, and the telematics are genuinely good. If you are not running a fleet, most of that is weight you pay for and never touch. I keep the parts a heating firm actually uses every day and leave the rest out.

The AI is the product, not a platform claim

I watch the week and hand you the fix: the job that cannot happen tomorrow, the quote nobody chased, the invoice that has gone quiet, the customer who needs telling you are running late. One tap and it is done, and nothing ever goes out without you seeing it first.

So, which one

Be honest with yourself

Choose BigChange if…

  • You run a larger, vehicle-heavy operation and want proper fleet telematics
  • You want the reassurance of their Gas Safe association
  • You are comfortable buying through a sales process and a quoted price

Come to me if…

  • You want to know the price without booking a meeting
  • You run a handful of vans rather than a fleet
  • You want to start the same day, on a free plan if you like
  • You want your engineers updating jobs from WhatsApp
