Top 10 Influencer Marketing Agencies UK 2026

The ten influencer marketing agencies in the UK most worth shortlisting in 2026 are Pulse Advertising, WPP, Socially Powerful, Billion Dollar Boy, Whalar, Disrupt Marketing, We Are Social, Manifest Group, Influencer Marketing Factory and Augmentum Media. The UK is the largest English-language agency market outside the United States, and its creator agencies range from global networks owned by holding groups to independent specialists in a single vertical. This guide compares all ten on the same seven criteria, services, technology, client portfolio, industry experience, innovation, reputation and local market expertise, and says plainly what each is known for and who it suits. It is a shortlist, not a ranking: the right agency depends on the brief.

HOW WE COMPARED THESE AGENCIES

1. Reputation and expertise. Industry recognition, awards from named bodies, and the agency’s stated specialism.
2. Services offered. What the agency does end to end, and where it hands off.
3. Tools and platforms. Proprietary technology for discovery, measurement or rights, and whether it is the agency’s own.
4. Industry experience. Years operating and the breadth of sectors served.
5. Client portfolio. Clients the agency itself names publicly.
6. Innovation and technology. Use of data, AI and measurement to prove outcomes.
7. Local market expertise. UK presence, and the ability to run UK work alongside other markets.

Two structural questions sit above the criteria, and we note them where they apply: whether the agency also manages creator talent, which bears on how creator selection is made, and whether it is independent or part of a holding group.

TOP 10 INFLUENCER MARKETING AGENCIES IN THE UK, 2026

01. Pulse Advertising

Known for

Pulse Advertising is an independent global influencer marketing and social media agency with 10 offices worldwide, including New York, and a London office serving UK brands. Founded in 2014 and not owned by a holding group, it runs multi-country campaigns from one central strategy team with local execution in each market, which is the reason it leads this list on the local-plus-global criterion: a UK brief at Pulse is usually one market of several run on the same brief and measured on the same system.

Location

London, with the agency headquartered in Hamburg and further offices across Europe, North America, the Middle East and Asia.

Key services

• Influencer marketing: strategy, creator selection, briefing, production oversight and usage rights across markets.
• Social media management: always-on channel strategy, content and community for brands running the UK alongside other markets.
• Paid social: amplification of creator content as partnership ads, planned with the organic work rather than after it.
• Measurement: campaign and always-on reporting through PI Metrics, the agency’s own platform.

Unique selling proposition

• Independence: no holding-group ownership, which the agency positions as freedom to select creators and media on the brief alone.
• One team, many markets: according to Pulse’s published case studies, it aligned more than 62 countries on a single global social media strategy for Nespresso.
• Proof in market: the agency designed and ran Cloetta’s 2026 US launch of Ahlgrens bilar, one of the five campaigns in our best influencer marketing campaigns of 2026.

Tech enablement

PI Metrics, Pulse’s proprietary AI measurement platform, used for monthly social ROI tracking across markets; Pulse’s case studies cite Ray-Ban as a client using it that way.

Notable clients

Nespresso, Ray-Ban and Cloetta, per Pulse’s published case studies.

Industry focus

Consumer brands: food and drink, beauty, fashion, eyewear and lifestyle.

Best fit: UK brands that also run, or plan to run, campaigns in Germany, France, Italy, the US or the Middle East and want one partner and one measurement system. Consider: Pulse is a full-service partner rather than a self-serve tool.

02. WPP

Known for

WPP is the London-headquartered holding group whose agencies offer influencer marketing as part of integrated creative, media and production services. In the UK its creator work runs through Ogilvy, VML and WPP Media (formerly GroupM), with production through Hogarth, all connected by WPP Open, the group’s AI-based operating platform. WPP also owns Goat, a dedicated influencer agency, which gives the group a specialist option alongside the full-service agencies. It is the choice for brands that want creators handled inside an existing holding-group relationship rather than by a standalone partner.

Location

London headquarters, with UK offices across its agencies and a global network in more than 100 countries, according to the group.

Key services

• Integrated creator programmes planned with brand creative and media on one account.
• Influencer strategy and execution through Ogilvy’s influence practice and VML.

Industry focus

Every category; the group’s agencies serve FMCG, automotive, technology, finance, retail, luxury and pharmaceutical brands.

Best fit: enterprise brands that already buy creative or media from a WPP agency and want creator work integrated with it. Consider: holding-group ownership is a factor for brands that want an independent partner, and a brief may be served by several WPP agencies at once, so ask who leads.
