Early Adoption Advantage
Voluntary reporting under UK SRS enables companies to begin sustainability disclosure ahead of the proposed mandatory start date of 1 January 2027,
which remains a proposal: the FCA Policy Statement that would confirm it had not been published as at 27 July 2026.
Early adopters build internal capabilities and stakeholder relationships in the meantime. UK SRS S1 and S2 are publicly available, enabling immediate voluntary implementation for companies seeking early adoption.
