The plug won't be fixed to anything, but the SWA, junction box and socket at the other end will be.
Using an extension lead for the entire length would not be fixed, but using an extension lead as a permanent installation won't comply with P1.
(neither would SWA, a junction box and a socket left laying around and not fixed).
