this is just what a few of our customers had to say...

"I've been using this software for a few months now and absolutely love it. So easy to use and understand. Couldn't be without it. Kicking myself for not getting it sooner."

Phil Mason

"Like many users ran the trial version first. signed up for the full version and have not looked back since, the software is improving all the time and the assistance online or phone is second to none. Because of its flexibility between tablets and PC I would highly recommend this App to any gas registered engineer/company."

Steve G

"Although I don't use this to its full potential I find this App a great time saver and as I add on my customers and it keeps the appliance records it will save even more time next year. I use it in conjunction with a I pad with a SIM card and my customers receive there certificates via e mail on completion of the job. a great time saver professional and the customers like it saves buying pads and you have the information to hand. Small price to pay for a professional tool."

Malcolm Codling

"This app has made life so much easier. Easy to fill out and sent immediately to customer & landlords. It takes out the pain of paperwork and sends a copy to your own email so no lost certificates and easy to file. We had looked at setting up something similar but when you find an app that suits thats already out there why bother. Highly recommend!"

Jomets H

"Software is excellent, thrown the old paper invoice books in the bin already!I'm one happy customer."

James Taylor

J.Taylor Plumbing & Heating
"We have been using the app for about 18 months now and I have to say I don't know how we managed without it. Simple to use, minimal paperwork and organising the engineers is a breeze."

Alan Hardman

Alfs Gas Appliance Services
"Transformed our business Having a CRM, quotes, invoices, gas certs & service records all in one place has saved so much more time & has therefore helped our business grow a lot quicker. Support is also 5* as they know what we are referring to & act on problems/requests immediately to get them resolved. Have been a user now for 6 months & very pleased, thanx GES ?"

Scott Priddey

"Great app! Have been using for a few months now and it's a nice simple to use app. Does exactly what it's supposed to, and if there is a problem with it, the support is really fast and efficient. Keep it up!"

Stuart Moffat

"Where would we be without this invaluable tool which helps so much to keep us efficient. It presents us as professional to our clients & keeps us highly organised which saves the cost of purchase many times over."

Alan Humphrey

Registered Gas
"Brilliant app, I've searched for gas engineer friendly app for very long time and since I've found this, no longer search for any other, I've used it for over a year now, very helpful, great feature such as gas rate calculator, stores all details which I can later access from my laptop or tablet. Fantastic app, highly recommend to every Gas Safe Engineer out there."
