Grew with my heating and plumbing business

Started using Gas Engineer Software when it was just me, I needed something simple for certs and invoices without the evening paperwork. Did the job perfectly.

Now I've got three engineers and the app's handled the growth without missing a beat. Scheduling, customer history, job tracking across the team, all in one place. Didn't need to switch to anything else.

Reliable day to day, support team are quick when you need them. If you're a sole trader worried you'll outgrow it, you won't!

Not useful

Not a straight forward setup. They should ask heating engineers before setting up such an app. The writing is so small that will send you to the opticians. The address is in red with underlines???? Why, let’s make it even harder to read. All round poor app.

Expensive

Been using this software for many years.

Not seen any real improvement in it. The price keeps going up and up.

Greed springs to mine.

Best app for heating and plumbing

Great app to create and sent all certificates, schedule jobs and manage jobs and engineers. I’ve been using it for almost a year and love it!

Does everything we need.

Been using it since I set my business up over 3 years ago. Everything works well although we don’t use everything the software is capable of. The team are constantly improving the software.
