This bulletin contains a high-level summary of the FCA’s position, and a snapshot comparing the UK and EU regimes.
New UK regime for ESG ratings providers
The FCA’s consultation paper on ESG ratings providers (CP 25/34) has been a long time coming.
- On March 30, 2023, HM Treasury launched a consultation proposing to bring ESG ratings providers within the scope of FCA regulation—this received support from industry. Over two years later, in October 2025, the government published legislation to this end. In December 2025, the legislation was issued in final form.
- The Financial Services and Markets Act 2000 (Regulated Activities) (ESG Ratings) Order 2025 amends the Financial Services and Markets Act 2000 (Regulated Activities) Order 2001 (RAO) to make the provision of ESG ratings a regulated activity for the purposes of UK law, subject to exceptions.
- The new regulated activity is set out in Article 63U of the RAO.
- The order comes into full force on June 29, 2028, but certain provisions apply before then to enable the new regulatory regime for ESG ratings providers to be put into place.
The FCA’s consultation paper was published for that purpose on December 1, 2025:
- It includes draft new rules for ESG ratings providers—these are to be introduced by inserting a new Chapter 6 into the FCA’s ESG Sourcebook. Chapter 6 is titled “Conduct rules for ESG ratings providers”.
- Draft guidance is to be added to the FCA’s Perimeter Guidance manual (PERG) on when activities are likely to amount to the new regulated activity of providing an ESG rating.
- As regards the “baseline” FCA rules that apply to most types of regulated firms, the consultation paper explains how the FCA proposes for these to apply to ESG ratings providers (e.g., PRIN, GEN, SUP, SYSC, TC, etc). The upshot is that much of the “baseline” regime will apply to ESG ratings providers, subject to specific exceptions—e.g., there is no need for an MLRO, a bespoke conflicts regime applies under the ESG sourcebook instead of the one in SYSC, the FCA’s consumer duty is disapplied, etc.
NB: On the subject of prudential requirements, interestingly, the following view has been taken: “We do not propose to introduce bespoke prudential requirements for rating providers. Our view is that existing requirements—Threshold Condition 2D (Appropriate resources), COND 2.4 and Principle 4 (a firm must maintain adequate financial resources)—provide a proportionate baseline.” Firms must therefore assess and maintain adequate financial resources and also have robust arrangements for an orderly wind-down. The FCA also makes clear the question of prudential requirements will remain under review
- Finally, the FCA uses the consultation paper to set out its approach to authorisation applications and to explain how it proposes to supervise ESG ratings providers going forward.
The FCA is to be commended for the overall approach taken to the consultation—it has engaged with industry extensively on the subject of ESG ratings providers, and signalled its desire to take an open, practical and collaborative approach. Since the consultation was issued, it has continued these efforts, with further extensive stakeholder engagement, which has been very well received.
Key points from the FCA’s draft rules
The new Chapter 6 to be inserted into the FCA’s ESG sourcebook for ESG ratings providers includes provisions on the following topics:
- Governance, systems and controls—including the methodology for formulating ESG ratings, and quality control, record keeping and outsourcing requirements, as well as the need to rely on up-to-date information when formulating ratings. One interesting point to note is that the FCA prohibits a firm from outsourcing “operational responsibility for the ESG ratings process”.
- Engagement—including the obligation to make certain notifications when the firm first decides to produce a particular ESG rating. Such a notification must include (among other things) the nature of the rating, the methodology, a summary of key data inputs, and an explanation of any rights to request data and how to notify the firm of errors. The FCA rules require information rights to be given to “notifiable persons”1 (e.g., so they can obtain certain data). The rules also impose various obligations—e.g., the firm must establish a procedure for receiving and processing feedback from stakeholders, and comply with certain requirements when requesting data.
- Complaints handling—the new regime will enable complaints by a ratings user, a “notifiable person” and “any other person with an interest in the ESG rating”.
- Transparency—this includes rules and guidance on disclosures designed to enhance the transparency and comparability of ESG ratings. It includes: (1) minimum public facing disclosures (including on conflicts and complaints handling); (2) disclosures and notifications to ESG ratings users and other “notifiable persons”. Further requirements apply where the firm wishes to make a change to a methodology.
The requirements on transparency contain an exception where information would qualify as a trade secret—the rules then prescribe what disclosures must be made instead.
- Conflicts—there is a bespoke and fairly extensive regime in ESG 6 on conflicts. Among other things, this includes rules on information barriers, and a conflicts of interest report to be regularly provided to senior management. The FCA rules also require ESG ratings to be free from political or economic interference.
Recommendations for firms
- Firms that will fall within the scope of the new regime will presumably be getting up to speed on the draft new rules proposed by the FCA and considering how to approach implementation and an authorisation application process.
- Firms that are frequent users of ESG ratings, and entities or firms that are (or have products that are) the subject of ESG ratings, may wish to review the FCA’s consultation paper so as to provide a response.
They may also wish to get involved in the work being done by relevant industry bodies on the subject of ESG ratings generally.
Broader landscape
Three other points worth mentioning from the consultation paper:
- The FCA notes that the UK government has identified sustainable finance as a growth-driving sector of the UK economy in “The UK’s Modern Industrial Strategy”.2
- The FCA notes that total global spending on ESG data is estimated to reach around USD2.2 billion in 2025, with further growth expected beyond that.
- The FCA refers to the evolving international landscape and the fact that several jurisdictions (including the EU) are introducing regulatory frameworks for ESG ratings providers. “Our proposals are designed to be consistent with international standards, particularly the IOSCO recommendations, to support cross-border coherence and reduce the risk of regulatory fragmentation.”
It is not clear, however, how much comfort this last statement by the FCA will provide in practice. For international groups, or firms doing business globally, having to face slightly different regulatory requirements across a number of different jurisdictions is far from ideal.
EU position
Turning then to the EU position, this is working to a timeline slightly ahead of the UK.
- The EU has introduced Regulation (EU) 2024/3005 of the European Parliament and of the Council of 27 November 2024 on the transparency and integrity of Environmental, Social and Governance (ESG) rating activities.
- This will begin to apply in the main from July 2, 2026. The UK regime, in the main, will begin to apply from June 29, 2028.
- ESMA has been working on regulatory technical standards (RTS) to support the new regime, and on October 15, 2025, published a final report on three draft RTS:
- One on authorisation and recognition—this deals with the information to be provided in applications to ESMA for authorisation and recognition.
- One on the separation of business (i.e., to address conflicts risks)—this deals with safeguards to be put in place to mitigate conflicts risks within firms that conduct more than just ESG ratings activities.
- One on disclosures to be made by ESG ratings providers to the public, users of ratings, rated entities, and (where relevant) the providers or issuers of rated items.
ESMA also confirmed as follows: “ESMA has submitted the draft technical standards to the European Commission for adoption by means of a Commission Delegated Regulation (for RTS). The technical standards will also be subject to non-objection by the European Parliament and Council.”
