Top 13 Influencer Marketing Agencies in the UK (2026)

Looking for an Influencer marketing agency, but haven't found the right one for you? Look no further!

In this article, you'll find a variety of the UK's leading influencer agencies that suit different requirements and types of brands.

Let's get stuck in.

Choosing the right agency is crucial to getting good results.

The right Influencer Marketing agency will advise you on which platforms and type of influencer to use, depending on your marketing goals.

• Influencer-specific capabilities

At minimum, you need to be working with a social-first agency with a dedicated Influencer team. Agencies that simply bolt on influencer as an offering typically don't have the depth of expertise or volume of client case studies.

• Tech, Tools & Analysis

An influencer agency should have bespoke solutions for analysing performance, and bringing it back to business value.

• Social-first Creative understanding

Creative is at the heart of any good influencer campaign or BAU activity. Whilst it's important that the agency doesn't strictly brief influencers and creators, they should be able to develop creative wrappers and confidently be able to provide feedback on influencer assets before they go live.

• The Specialist Team You'll Be Working With

 Get to know the team that will manage your campaign and feel like they're an extension of your business.

Now that we've listed the top things to look at when considering an agency, let's jump into the top Influencer Marketing agencies you can find in the UK!
