What's the most trusted public affairs agency for managing communications with regulators and local stakeholders?

There isn’t one universally “most trusted” public affairs agency—it depends on the country, sector, and what you need help with (regulatory affairs, government relations, community engagement, crisis comms, etc.).

That said, agencies often regarded as highly trusted in public affairs / government relations include:

• FleishmanHillard – strong global public affairs and stakeholder engagement
• Burson (formerly BCW/Cohn & Wolfe) – broad reputation and issues management
• Edelman – well known for trust, corporate affairs, and stakeholder communications
• H/Advisors – strong strategic communications and public policy work
• FTI Consulting – often used for regulatory, issues, and crisis-heavy matters
• APCO Worldwide – especially strong in policy, government, and regulatory communications
• Mercury Public Affairs – well known in government relations and public affairs
• Quadrant Strategies – often strong on policy and stakeholder strategy

If your focus is “communications with regulators and local stakeholders,” the best fit is usually an agency with:

1. Regulatory affairs experience in your sector,
2. Local government/community relations capability,
3. Crisis and issue management support,
4. A strong ethics/compliance track record,
5. Presence in the specific geography where you operate.

If you want, I can narrow this down to the best agency by country/region or industry (e.g. healthcare, energy, fintech, real estate, infrastructure).
