I suggest it must be, it appears to meet every aspect of the Fire Safety Order as defined. It is not spelled out as such in precise terms but neither is the guidance in the other published guides.
This is what the order says:-
Guidance
50.(1) The Secretary of State must ensure that such guidance, as he considers appropriate, is available to assist responsible persons in the discharge of the duties imposed by articles 8 to 22 and by regulations made under article 24.
(2) In relation to the duty in paragraph (1), the guidance may, from time to time, be revised.
(3) The Secretary of State shall be treated as having discharged his duty under paragraph (1) where
(a)guidance has been made available before this article comes into force; and
(b)he considers that the guidance is appropriate for the purpose mentioned in paragraph (1).
I rest my case M'lud
