PLASTIC PIPING

[STI]

After a recent visit from a plumber (i think more odd job man) my friends have been told that all their piping , hot water, central heating needs to be changed because its plastic and therefore dangerous, Is this true are there any rules and regs where plastic piping can or cant be used in a domestic situation..
I am suspicous of this character because he also told them all their loft wiring needs to be changed because its flex not cable. The only flex up there is for the ariels

Nothing wrong with plastic piping. Many new builds now are all plastic.

It isn't flex then - it'll be coax .

And as for plastic pipe - it depends on the type of plastic and the specific purpose it is being used for.

Non-barrier on heating is a no no.

Plastic on gas a bigger no no.
