yes anyone can install a boiler if your corgi or competent.
but if your a d.i.yer and think your competent and you make a f**k up the courts will see you as not competent and give you a nice big fine.
it is also illegal to install a boiler for money if your not corgi.
i have never met a d.i.yer that can do a soundness test, purge the gas, gas pipe sizing, etc i could go on
so in common sense the d . i . y er is not competent
of cause blow yourself up by all means but not everyone one around you........
