KPMG, PwC, Deloitte, and EY implementation studies converge on this range for a mid-cap listed company to build the data infrastructure, materiality assessment, quantitative scenario analysis, and disclosure drafting needed.

How long UK SRS S2 implementation actually takes

Companies waiting for the FCA Policy Statement to begin preparation are already late. Practitioner consensus puts end-to-end implementation at twelve to eighteen months — driven by Scope 3 data, which can't be compressed.

Critical path
18 months

From kickoff to first UK SRS S2 report. Driven by Scope 3 supplier engagement and quantitative scenario modelling — neither compressible.

Scope 3 dominance
14 months

Of Scope 3 data work — from supplier engagement onset through validation. Of the 15 GHG Protocol categories, Category 1 and Category 11 typically account for >70% of total Scope 3 emissions.

Earliest sensible start
3 months

Foundation phase before data work meaningfully begins. Materiality assessment and gap analysis are pre-requisites — running data collection without these creates wasted effort.
