Platic pipes near radiators

[Frankey]

Hi guys. I'm getting the radiators installed in my property now and I'm struggling between plastic and copper pipes to radiators. I've asked 2 plumbers and they said opposite opinions. The first one said only copper pipes is allowed into radiators, and the second plumber agreed to install plastic ones. Is there a difference in terms of safety and durability? Is the first plumber being too conservative or the second one negligent?
Looking forward to your opinions, ta
Frank

Depends on how they are piped if coming up out of the floor then I would only fit copper, if in walls and concealed coming out behind rads then plastic fine. It’s safety and aesthetics as pipes get banged and caught while hoovering. That just my thoughts but if I was fitting then would be all copper.

Copper for me. I use very little plastic.
