Gas Checker 4+

I've been using this app since 2012 , I do hundreds of cp12's every year and it sends reminders to customers by email. I use it for all my invoices, warning notices and CP12’s. It has been amazing as I’m useless with paperwork! Everything is stored and if any issues the technical is amazing ( I just asked for my clients invoices for last tax year and they send a spread sheet! WOW!
I had 8 years on this app and the cost of around £10 per month is too cheap. I lost my phone last year and they simply back up all my 7 years to the new phone.
Best thing ever for Gas engineers.

I’ve been using this software for a couple of years or so and it has been very useful but the last update still hasn’t addressed the problem with sending multiple pdf attachments and I’m losing time using this now.
I find the layout of the app much better than other ones that are available and filling out certificates and renewing them is straightforward and quick.
The desktop site is not very well planned and I don’t bother with it much. The page needs to reload too often, you can’t send multiple pdfs from the desktop site without downloading them individually which makes cloud storage redundant and the reminders don’t work very well and it shows outstanding jobs for jobs I’ve already done.
3 stars... I think it’s more usable on site and easier to navigate than other apps I’ve tried but will they manage to sort the multiple pdf issue before I jump ship... who knows?

Brilliant app for for gas safety’s and invoicing, been using it for 3-4 years now and never had a problem, if I have a query the team are on hand to sort it out, can’t speak highly enough of them, highly recommend going pro+, I started off lite for an extra £6-£7 you get access to every service. Keep up the good work guys and thanks for making my working day a lot easier.
