maybe, but thing is... a lot of plumbers are like this now, everything's plastic pipe with the bulky quick fittings.
I cringe every time I see it used, in some instances in the past where possible ive even ripped it out and replaced it with copper just to make a decent job. Its not even like they cant do copper work as most do gas work and you have to use copper for the gas pipes... just laziness, certainly not cost as the fittings are a heck of a lot more expensive than end feed solder copper fittings.
One reason why I am not completely for how society has become whereby you need to be qualified to do anything, it does not really improve things.
in the case of plumbers, there was time served plumbers who actually took pride in their work and did some real great work, but now they aren't allowed to touch electrics because they "aren't qualified" or "not registered with a governing body" but ive seen some qualified plumbers and look at their work and wonder how they even got qualified, they don't even follow the regulations themselves.
seen same with windows and doors, Fensa registered installers leaving installations with gaping gaps and drafts... yet the guy who does it properly, seals it with not a single draft is the one who is in breach of building regulations unless they notify it and pay a hefty fee.
qualifications just don't necessarily improve things.
