New app designed by registered gas engineers for registered gas engineers

Gas App UK is essentially a one-stop shop for every information resource related to the day-to-day work of gas engineering.

The app is different from existing apps for gas engineers because it is created by experienced, registered gas engineers.

It includes just some of the following:

• Manuals for boilers, gas fires and warm air units
• Documents such as warning notices, gas safety records and job sheets
• Useful tools such as a Pipe Sizing Calculator, Combustion Ratio Guidelines and Purge Calculators
• Servicing checklists
• ACS refresher sections
• Horror show picture galleries
• Newsroom with live up to the minute industry gossip and news
• Engineer timeline / discussion areas

Quality app

I use this app often, for the manuals and fault finding section, unlike other sources you get helpful advice not put down for needing to ask.
As for the price it’s more than fair for the information available and the time and energy put into the app by the developers, I personally can spend more money on a takeaway on a Saturday night with less regret and more enjoyment.

Fantastic community

Been using the GasApp for over 12 month, the community is fantastic, everyone is always on hand to help, no need to spend hour speaking to manufactures, Ant Provan is a great guy and the guys from sterling, the app is evolving with the times. Great access to manufactures manuals, competitions, tools, office for quotes and invoices and access to the finance scheme, I’d be lost with out the GasApp 🙂😍. The time I save on the jobs is worth the yearly fee for the App 🤗🤗

Essential piece of kit!

I’m fairly new to the app but can already see this going to to be an essential app on my phone!
Going through the app I can see the developers have put a lot of time and effort in and actually care about the user! Unlike other apps that just take the money and run.
