FCA finalises rules to bring ESG rating providers into UK regulatory perimeter

By The Financial Edition · 4 November 2026 · 06:33 GMT · Insurance Business UK · 1 min read

Authorisation timeline and core requirements

The Financial Conduct Authority has published policy statement PS26/22, establishing that firms providing environmental, social and governance ratings in the UK must secure authorisation and the appropriate regulatory permissions from 29 June 2028. Eligible providers can submit applications beginning 24 June 2027, with the regulator urging firms to apply early within their designated windows. The framework introduces mandatory standards covering transparency in methodology production and communication, governance structures, internal systems and controls, and the management of conflicts of interest. It also requires providers to engage formally with both rated entities and rating users, though the rules do not dictate specific sustainability methodologies.

Implications for insurers and corporate clients

Because ESG ratings directly influence underwriting decisions, investment strategies, and corporate risk reporting, the regime aims to improve the reliability of data used across financial markets. For commercial insurance brokers and their clients, the mandated engagement obligation provides a regulated mechanism for businesses to discuss and formally challenge ratings used in insurer risk models ahead of policy renewals.

Why it matters

While authorisation is not required until mid-2028, the rules establish a formal right for rated businesses to engage with and challenge ESG data providers, changing how corporate clients manage their risk profiles ahead of insurance renewals.

Jargon, explained

underwriting: Assessing a risk and deciding whether to provide insurance, at what price and on which terms.
