Sustainability & ESG

Clear, disciplined and assurance-ready sustainability support, grounded in recognised international standards.

Let’s talk

Where sustainability reporting actually stands

The position moved considerably in the first half of 2026, and a good deal of what companies are preparing for no longer applies to them. This is the current position.

  1. In force now

    TCFD-based requirements continue

    The Companies (Strategic Report) (Climate-related Financial Disclosure) Regulations 2022, the FCA listing rules and SECR all remain unchanged. If you reported last year, you report this year on the same basis.

  2. Feb 2026

    UK SRS S1 and S2 published

    The UK’s endorsement of ISSB IFRS S1 and S2 was published on 25 February 2026. Available for voluntary use by any entity. No legislation yet mandates them.

  3. Feb 2026

    EU Omnibus narrows CSRD

    Third-country thresholds rose to €450m EU turnover with a €200m EU subsidiary or branch, from €150m and €40m. Most UK groups previously in scope are now out of it. Re-run your assessment before spending more on readiness.

  4. Mar 2026

    FCA CP26/5 closed

    The consultation on aligning listed issuers’ disclosures with UK SRS closed on 20 March 2026. A policy statement is expected in autumn 2026.

  5. From 2027

    Mandatory for listed issuers

    Rules are proposed to take effect from 1 January 2027, applying to accounting periods beginning on or after that date. Core climate disclosures mandatory, wider disclosures on a comply-or-explain basis.

  6. Then

    Assurance follows

    Whatever the timetable, the disclosures will eventually need to withstand assurance. Data that cannot be traced to a source, a control and an owner will not survive that. Building the plumbing is the actual work.
