Voluntary use, the FCA's listing rules and the Companies Act route

UK SRS S1 is a final standard available for voluntary use — who must apply it is fixed by listing rules and legislation, not by the standard. The FCA's final rules in PS26/19 apply it on a comply or explain basis to five listing categories from 2027; a Companies Act route has no timetable yet. These guides separate the technical standard from the legal trigger.
