doesnt say if there is any paperwork relating to the installment of the lpg system also i thought there had to be some sort of certificate to go with it
all the other paperwork is mentioned/photographed
i may 100% wrong on this but was the case a few years ago on after market installs
There is a a whole lot of bs and hoarse crap around all that.
Approved installers have to supply an LPGA certificate. LPGA being the driving force behind a jobs for the boys approach from the industry generally. Its a bit of a stitch up, claiming that diy installs are dangerous and should be legislated out of existence on safety grounds. Which all very conveniently works in the LPGA,'s favor. More work for them.
But the laugh of it is most LPGA approved installs we see on here could have been done more professionally down the local zoo, and when diy installs are presented for safety certs(insurance requirement only) take a hard line overly fussy view on order to appear superior. Now we all make mistakes.

but I've yet to see too many of these overly fussy faults make a blind bit of difference in practical terms.
Yes there should be some regulation, but these guys need to look in the mirror before looking under a bonnet in most cases.
Although to be fair, on diy installs, it is Gas, which is not to be messed with and these guys sign their name to our work, it's their lively hood, and our blood on their hands if it goes wrong. It has to be right, and if there's an issue I want to know about it.
