EU Stop-the-Clock Directive: Updated CSRD and CSDDD Timelines Every UK Company Should Know
Key Takeaways
- The EU “Stop-the-Clock” Directive (April 2025) delays CSRD Wave 2 by two years — from 2025 reporting to 2027 — giving large EU companies additional preparation time
- CSRD Wave 3 (listed SMEs) has been delayed from 2026 to 2028 and will subsequently be fully exempted under the Omnibus proposals
- CSDDD (Corporate Sustainability Due Diligence Directive) transposition deadline pushed from July 2026 to July 2028
- UK subsidiaries of EU parent companies gain breathing room, but Wave 1 companies (largest EU-listed) are already reporting and their data demands cascade down
- The risk of complacency is real — companies that use the delay to defer preparation rather than extend it will face compressed timelines when requirements take effect
What the Stop-the-Clock Directive Changes
In April 2025, the European Union adopted the “Stop-the-Clock” Directive as part of the broader Omnibus simplification package proposed by the European Commission in February 2025. The directive amends the application timelines for two major pieces of sustainability legislation:
CSRD (Corporate Sustainability Reporting Directive):
- Wave 1 (largest EU public-interest entities, 500+ employees): Unchanged — reporting for financial years beginning on or after 1 January 2024. These companies are already reporting
- Wave 2 (large companies meeting 2 of 3 criteria: 250+ employees, EUR 50m+ turnover, EUR 25m+ total assets): Delayed two years — from financial years beginning 1 January 2025 to 1 January 2027
- Wave 3 (listed SMEs): Delayed two years — from 2026 to 2028. Under the fuller Omnibus proposals, listed SMEs will subsequently be exempted entirely from CSRD
- Non-EU companies (EUR 150m+ EU net turnover): Delayed two years — from 2028 to 2030
CSDDD (Corporate Sustainability Due Diligence Directive):
- Member State transposition deadline: Delayed one year — from 26 July 2026 to 26 July 2027
- First companies in scope: Delayed to 26 July 2028 (from July 2027)
- Under the Omnibus proposals, CSDDD scope will also be significantly narrowed, with the turnover threshold raised from EUR 450m to EUR 1 billion
Implications for UK Companies
The Stop-the-Clock Directive has several direct implications for UK businesses:
UK subsidiaries of EU groups. If your UK company is a subsidiary of an EU parent company that falls into Wave 2, you now have until 2027 (reporting in 2028) before your parent is required to include your data in its consolidated CSRD report. This provides additional time to implement data collection systems, but the direction of travel is unchanged — the requirement is delayed, not removed.
UK companies with EU operations. If your UK company has qualifying EU operations (subsidiaries, branches) and meets the Wave 2 thresholds, your CSRD reporting obligation is delayed to 2027. This is significant breathing room, particularly for companies that had been racing to implement ESRS-aligned reporting processes.
UK companies in the EU supply chain. Even though Wave 2 is delayed, Wave 1 companies are already reporting. These largest EU companies are already requesting sustainability data from their supply chains — including UK suppliers. The delay for Wave 2 does not reduce the data demands flowing from Wave 1 companies to their UK supply chain partners.
Non-EU company scope delayed to 2030. UK companies that would have been caught by the CSRD’s non-EU company provisions (EUR 150m+ EU net turnover, with an EU subsidiary exceeding certain thresholds) now have until 2030. However, this provision may be further amended under the Omnibus proposals.
The Risk of Complacency
The most significant risk from the Stop-the-Clock delay is that companies treat it as a signal that sustainability reporting requirements are being softened or withdrawn. They are not. The delay is administrative — driven by the EU’s recognition that implementation capacity (particularly among assurance providers and standard-setters) was insufficient for the original timeline.
Companies that defer preparation entirely will face several problems:
- Compressed timelines: When 2027 arrives, these companies will need to implement ESRS-aligned reporting from scratch in 12 months, rather than having had the original 24-month runway
- Assurance provider scarcity: The delay concentrates demand for CSRD assurance services into a shorter period. Companies that engage assurance providers early will secure capacity; latecomers may struggle
- Data system gaps: ESRS requires granular data across environmental, social, and governance topics — including value chain data that requires supplier engagement. This data collection infrastructure cannot be built overnight
- UK SRS convergence: UK companies also face mandatory UK SRS reporting from January 2027. Companies with dual UK-EU reporting obligations should use the CSRD delay to build integrated systems that serve both frameworks
CSDDD: What the Delay Means in Practice
The CSDDD imposes human rights and environmental due diligence obligations across corporate value chains. The one-year transposition delay (to July 2027) and the subsequent application delay (to July 2028) provide relief, but the broader Omnibus simplification proposals may reshape the directive more fundamentally:
- The revenue threshold for scope may increase from EUR 450m to EUR 1 billion, significantly reducing the number of companies in scope
- Value chain due diligence may be limited to Tier 1 suppliers (direct contractual relationships) rather than the full value chain
- Civil liability provisions may be softened
For UK companies, the CSDDD is relevant primarily if they have EU subsidiaries or branches that bring them into scope. The UK has no equivalent legislation, though the Modern Slavery Act and upcoming provisions under the Environment Act create partial overlaps.
What You Should Do Now
- Update your compliance timeline to reflect the new dates: CSRD Wave 2 at 2027, CSDDD at 2028
- Do not stop preparation. Use the additional time to build better systems, not to defer action. Companies that arrive at 2027 with mature data systems will have a significant competitive advantage
- Respond to Wave 1 data requests. Your EU customers and investors in Wave 1 scope are reporting now and need your data. These requests will intensify, not diminish
- Integrate UK SRS preparation. UK-listed companies face mandatory UK SRS from January 2027 — the same year as the delayed CSRD Wave 2. Build one system that serves both
- Monitor the Omnibus proposals. The Stop-the-Clock is an interim measure. The full Omnibus package will make more substantive changes to scope, content, and assurance requirements. Final adoption is expected in late 2025 or early 2026
