Brussels Office Since


Firm Description

Founded in 1998, the Hanover Group celebrated its 22nd year in 2020 as a 180-strong strategic consultancy with offices in London, Brussels, Dublin and the Middle East.

The company’s mission is to improve the reputation, recognition, relationships and results of every business, institution, individual and organisation we advise. We design and deliver strategies that unlock insight, shape narratives, harness influencers, activate campaigns, navigate regulations and access markets.

Our strategic approach is underpinned by data-led research and robust measurement practices to ensure that we create outstanding returns for our clients.

We pride ourselves on hiring the best people and investing heavily in innovation to enable them to deliver outstanding client work. Hanover’s entrepreneurial, collaborative and excellence-driven culture is underpinned by six core values: “Know your stuff”, “Be trail-blazing”, “Tell it like it is”, “Give your all”, “Remember how good you are” and “Show respect”.

Key Strengths

Hanover Brussels is a leading independent communications and public affairs consultancy located in the heart of the EU quarter. Our team works closely with businesses, trade associations, NGOs and public sector bodies to bridge the gap between their business objectives and the policy environment they operate in.

We provide tailored integrated services across the spectrum of public affairs, corporate communications, and media relations to clients in healthcare, financial services, media, technology, transport, environment, FMCG, energy and international trade.

Our ability to deliver distinctive political intelligence and analysis enables us to develop bespoke EU and international advocacy, reputation and relationship building campaigns that make a difference. In healthcare we have a specialism in supporting companies to strengthen their market access strategies through shaping the external policy and regulatory environment.

The team is led by Christian Hierholzer, Claudia La Donna, and Emma Eatwell.

In addition to having been named Global Public Affairs Agency of the Year twice by The Holmes Report in recent years, in 2020 Hanover was listed among the EMEA Agencies of the Decade by PRovoke.

Thought Leadership

At Hanover, we speak often about the need for ‘uncommon sense’ in uncertain times such as these. The path towards Net Zero may seem lengthy but business planning needs to start now, with companies and governments taking an integrated approach from the very beginning to ensure that they are on track to meet targets.

Read our latest report Net Zero Unpacked: the Essential Guide on how businesses must play a key role, taking responsibility, leading the debate and driving their purpose. To ensure change, our businesses need to be that change.

As the world prepares for the forthcoming revolution brought about by the growing prevalence of AI, we asked whether companies are ready for the potential reputational and regulatory challenges that come with this in our latest report, Decoding Brand Reputation in the Age of Artificial Intelligence.
