Best Advertising Agencies in Brussels (2026)

Introduction

Brussels is home to the Belgian offices of most international advertising networks, and the seven agencies below are the ones we could verify with an active Brussels office and current work in 2026. They range from Omnicom and WPP network offices to a partner-led European group and two independents.

The market’s client base is unusually mixed. National brands in telecoms, banking, retail and mobility sit alongside EU institutions, NGOs and trade associations, and campaigns often run in French and Dutch, with English added for European work. The network map has also shifted. Omnicom completed its acquisition of IPG at the end of 2025 and retired the DDB, FCB and MullenLowe brands, which affects former DDB and FCB clients in Belgium. WPP’s Brussels offices for VML and Ogilvy now share one building in Saint-Josse-ten-Noode.

Each agency here has a Brussels office in 2026, confirmed from its own site or a recent trade profile. The list is unranked, as the right agency depends on your brief, your languages and how you like to work.

The best advertising agencies in Brussels

1. BBDO Belgium

Omnicom · Zaventem · bbdo.be

BBDO Belgium is Omnicom’s BBDO network in the country, with its Brussels office on Excelsiorlaan in Zaventem, just outside the city, and a second office in Antwerp. BBDO is one of the three creative networks Omnicom kept after folding IPG’s agencies into its own in 2025 and 2026.

Recent work on its site includes Christmas gifting for the department store INNO, campaigns for the telecoms brand Hey!, news-led work for the newspaper Gazet van Antwerpen, and a remix campaign for the bakery chain Panos. The client mix leans towards Belgian retail and consumer brands.

2. TBWA\Belgium

Omnicom · Brussels · tbwagroup.be

TBWA\Belgium is Omnicom’s TBWA network in Belgium and a member of Creative Belgium. It sits within a wider TBWA group in Brussels that also includes Pride\TBWA, a PR and influencer agency in Ixelles. Under Omnicom’s consolidation, TBWA is the default home for DDB, FCB and MullenLowe agencies in markets without a separate plan.

Brussels Airlines and McDonald’s Belgium are its most visible clients in 2026. For Brussels Airlines it ran a January campaign turning planes overhead into prompts for a getaway and, in June, a giant message to the national team ahead of the World Cup. For McDonald’s it launched “Chick-A-Boom” in April. Earlier work includes Telenet, and a 2025 Lipton Ice Tea campaign with the rapper Ice-T.

3. VML Belgium

WPP · Saint-Josse-ten-Noode · vml.com/belgium

VML Belgium is WPP’s merged creative, digital and commerce agency in the country, with offices in Brussels (Square Victoria Régina in Saint-Josse-ten-Noode) and Antwerp. The agency says it was the first in Belgium to be named Creative Agency, Digital Agency and Ad Agency of the Year in the same year.

Its case studies include retail work for Telenet, “Update Yourself” for the travel group FTI, and a long run of campaigns for Child Focus, among them “The Emergency Exit” and “Miles for the Missing”. Q8 and the city of Sint-Truiden also appear. Its site also carries VML’s Future 100: 2026 trends report.

4. Ogilvy Belgium

WPP · Saint-Josse-ten-Noode · ogilvy.com/be

Ogilvy Belgium works from the same WPP building on Square Victoria Régina as VML, and runs a social practice under the Ogilvy Social.Lab name. Its Belgian client list is one of the broadest in the city, covering consumer brands, public bodies and EU work.

Projects include “Safeonweb@work” for the Centre for Cybersecurity Belgium, “We See Africa” for the European Commission’s Directorate-General for International Partnerships, a TikTok playbook for visit.brussels, and work for KBR, the Royal Library of Belgium. Commercial clients include Dove, IKEA Belgium, Ford of Belgium and Luxembourg, Nespresso and L’Oréal Groupe. Clients that want EU and federal-government experience alongside retail work will find both here.

5. Serviceplan Belgium

Serviceplan Group (independent, partner-led) · Brussels · serviceplan.be

Serviceplan Belgium is the Brussels office of the Munich-based Serviceplan Group, which describes itself as Europe’s largest independent and partner-led creative agency. It sits within the group’s House of Communication structure alongside media and digital sister agencies.

BMW is a major client, with work including “The Symphony of Unity” for BMW at Tomorrowland and an awareness campaign for its electric range. It also handles ALDI’s price and quality advertising, and in October 2026 launched “Next Level” for MediaMarkt with Serviceplan Group Benelux.

6. Happiness

Formerly an FCB alliance · Brussels · happiness-anywhere.com

Happiness is based in Brussels and also works from Saigon and Amsterdam. For many years it traded as “an FCB alliance”; the FCB brand was retired in Omnicom’s 2025 to 2026 consolidation, and the agency now presents itself under its own name. At Eurobest 2025 it won a Grand Prix, a Gold, two Silvers and two Bronzes for Burger King, and was named Best Belgian Agency at the festival.

Current clients include Lotto, with a Friday the 13th campaign built around its black cat, the pasta brand Soubry, SPA, 2dehands, Verisure and Amplifon. In 2025 its World Animal Protection campaign hijacked YouTube’s 20th anniversary to give elephants a voice.

7. Air

Independent, exclusive partner of McCann · Watermael-Boitsfort · air.be

Air calls itself Belgium’s first independent agency and is the exclusive Belgian partner of McCann, which Omnicom kept as one of its three global creative networks. It works from Chaussée de La Hulpe in Watermael-Boitsfort and says its own operations are carbon neutral.

Recent work includes several campaigns for the health insurer Partenamut, one of them on mental health, campaigns for Bancontact Pay, work for CBC Assurances, and a Sony Music film that retells Little Red Riding Hood to talk about street harassment. It also made a Brussels campaign asking for respect towards emergency services. Most of its press releases are written in French.

What to look for in a Brussels advertising agency

Start with language. Most Belgian campaigns need French and Dutch versions, and EU or international work adds English. Some agencies write natively in both national languages; others lead in one and adapt into the other. Ask who writes each version and whether Dutch and French copy are created in parallel or translated afterwards, as it shows in the finished work.

Check how the network changes affect your account. The Omnicom and IPG merger retired the DDB and FCB brands, and WPP merged several of its agencies into VML. If your agency was part of one of those moves, confirm which team, office and media partner will handle your business in 2026.

Think about the client mix you want next to you. Brussels agencies split between those built around national consumer brands and those with deep public-sector and EU experience, where procurement runs through framework contracts and approvals involve several stakeholders. Both types are well represented above, and it helps to ask for examples close to your own sector.

Finally, look at how the agency runs reviews. A single TV spot can travel through two language versions, several cut-downs and a round of legal checks, and feedback from different teams arrives in different places. Agencies with one place for the latest files and a clear record of who approved what save a lot of time on multilingual campaigns.

How Fabric helps advertising agency teams

Fabric gives an agency one workspace for its files, client feedback and team knowledge, with AI search across all of it. The agency setup suits the way Brussels shops work: one space per client, holding briefs, scripts, French and Dutch versions, decks and call notes together.

Campaign films and print masters sit in Fabric’s cloud drive, which streams files on demand so they take no local disk space and heavy video opens without a full download. Search works by meaning across documents, images and recordings, and audio and video transcription makes every spot and voice-over searchable, with results that jump to the timestamp.

Review runs through sharing. An agency shares a file or folder with the client as a commenter, and the client can open it through the link without signing up. With annotations, they leave timestamped comments on video and audio, draw on a video frame or an image and attach a comment to the drawing, or highlight copy in a script or PDF. The team marks each comment completed as it is handled, so a round of feedback works as a checklist across both language versions. There is more on this in review and approval.

For final delivery, any file or folder can be published as a web page for viewing and, if allowed, download, with password protection and link analytics that show when each named recipient opened it. On Team plans, self-writing docs keep a page for each client, covering decisions, deliverables and open items, drawn from meetings, Slack and the workspace.

Password protection and link analytics are included on Pro and Team plans, and self-writing docs on Team plans. See plans for teams.

Frequently asked questions

What is the best advertising agency in Brussels?

There is no single answer, since the right agency depends on the brief. On recent recognition, Happiness was named Best Belgian Agency at Eurobest 2025, and VML Belgium says it was the first agency in the country to win Creative, Digital and Ad Agency of the Year in a single year.

What happened to DDB Brussels?

Omnicom retired the DDB brand after completing its acquisition of IPG at the end of 2025. Campaign reported that DDB agencies in markets without a separate plan merge into TBWA, and Belgium was not named among the exceptions. Former DDB Brussels clients should confirm with Omnicom which team now holds their account.

Is Happiness still part of FCB?

Happiness worked for many years as an FCB alliance. FCB was one of the brands Omnicom retired in its 2025 to 2026 consolidation, and Happiness now presents itself under its own name, with offices in Brussels, Saigon and Amsterdam.

Do Brussels advertising agencies work in both French and Dutch?

Most do, as national campaigns need both languages. Ask whether each version is written by a native copywriter or translated, and check examples in both. For EU and international briefs, English is common as well.

What is the difference between an advertising agency and a creative agency in Brussels?

The terms overlap. This list focuses on network offices and agencies whose main output is advertising campaigns. For independent idea shops and integrated studios, see our list of creative agencies in Brussels.
