The Financial Conduct Authority (FCA) has invited ESG rating providers to participate in a voluntary reporting pilot, a move designed to refine the UK’s upcoming regulatory framework for the sector. The regulator is seeking to develop a “proportionate” regime that avoids unnecessary administrative burdens while ensuring robust market oversight.
The pilot follows the publication of Consultation Paper CP25/34, which outlines the FCA’s proposed approach to regulating ESG ratings. By engaging with firms now, the regulator aims to test whether proposed reporting metrics are clear, feasible, and useful for supervisory purposes across various business models.
ESG rating providers who expect to fall within the scope of UK regulation have until 13 May 2026 to register their interest. Participants will have a direct influence on the final design of the reporting framework and the specific metrics that firms will eventually be required to disclose.
“Our aim is to avoid unnecessary reporting burden for firms over time,” the FCA stated, noting that feedback from the pilot may lead to revisions of the metrics before the formal regime goes live.
The pilot will specifically explore the accessibility of data, including non-public datasets, to ensure the new standards are grounded in practical market realities. The FCA clarified that the data provided during this pilot is for framework development only and will not be used to inform individual authorisation assessments. Firms currently applying for authorisation are reminded that any relevant information must still be included in their formal applications.
Depending on the volume of interest, the FCA may select a representative sample of firms to ensure a diversity of business models is represented in the findings.
The initiative marks a significant step in the UK’s efforts to bring transparency and standardisation to the ESG ratings market, which has become a critical component of global capital allocation and corporate sustainability strategy.
