Brussels Office Since

Firm Description

H/Advisors has been present in Brussels since 2008, serving as the central hub for Public Affairs. Wherever decisions are made across Europe, from EU institutions to national capitals, H/Advisors is there.

Our pan-European network combines deep local intelligence with a single, integrated strategic voice, delivering tailored counsel to organisations navigating pivotal moments across every major EU market. Behind every office is a team that knows the players, the politics, and the pressure points, not just mapping the landscape — but operating within it.

We provide public affairs, regulatory strategy, intelligence, senior advisory and strategic communications that shape public opinion, influence policy outcomes, and drive action at the intersection of business, society, and government. Our hub and spoke model ensures high-impact advocacy rooted in local insight, political nuance and targeted engagement.

We operate across the full architecture of EU influence: the Commission, Parliament, Council, national governments, industry coalitions, and global stakeholders shaping Europe’s agenda.

Ownership Structure

H/Advisors is part of Havas, one of the world’s largest global communications groups, with more than 23,000 people across 100 markets.

International Network

Founded in 2001, H/Advisors employs over 1,500 multi-disciplinary experts across more than 40 offices spanning Europe, the Americas, APAC and the Middle East.

Our teams combine deep industry expertise with a problem-solving ethos, partnering with leaders to deliver outcomes, not just advice.

Key Strengths

• EU institutional lobbying: Shaping EU law, regulation, and policy across sectors with direct access to key decision-makers and measurable commercial impact.
• Pan-European communications campaigns: Influencing EU institutions, governments, regulators, industry coalitions, and tier-one media through targeted, audience-specific narratives.
• Reputation & image management: Strengthening and protecting organisational positioning across Brussels, Member States, and the wider public sphere — where reputation is leverage.
• EU relationship capital: Two decades of trusted relationships across the Parliament, Commission, Council, and national delegations — enabling access that goes beyond traditional lobbying.
• Breakfast with a View: H/Advisors rooftop event series that brings together political leaders, senior executives, and policy experts for focused discussions on key European issues. Each session combines a networking breakfast with an intimate, high‑level conversation led by a single guest speaker and a small group of participants.
