Must some electric clips be metal?

http://wiki.diyfaq.org.uk/index.php/...l_Installation

Looks like from Jan 2019.

This new requirement (which comes into effect from 1 January 2019) will
make it compulsory to use metal cable fixings within the whole
installation and not only on fire resistant cables. This does not mean
that every cable clip must be non-metallic but the cable must be fully
supported in the event of a fire.

This is in part due to the death of a fireman who, after entering a
building became trapped by burning cablss which fell of the wall and
blocked the only escape route.
