User reviews

Excellent Software for Gas Engineers!

As a self-employed Gas Safe engineer running a small heating and plumbing business, I’m really impressed with Gas Engineer Software so far!

It’s easy to use, well organised, and has everything I need in one place — customer records, boiler history, gas safety certificates, service reports and automatic service reminders.

I particularly like being able to keep a complete history of each customer and their appliances. It makes running my business much easier and more professional.

I’m still relatively new to the app, but my first impressions are excellent. Looking forward to using it as my business grows. Highly recommended to other gas engineers!

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.

Yet another evening wasted when I should be invoicing and catching up with a busy week but can’t due to yet more maintenance with zero notice. Happy to spam us with pointless podcasts but can’t be bothered to warn us with site shut downs.

I would use this lot again. Looking at moving.

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!

Response from developer

Thank you for your review - we're happy to hear you and your team have been getting value out of Gas Engineer Software!

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.
