Top 13 Social Media Agencies In The UK (2026)

Finding the right Social Media Agency in the UK is not easy.

A few years ago, there were few and far between, but now the market is littered with agencies saying they can do Social... but do they really have the expertise and proven track record required?

So, we want to save you from getting burnt with this list of the UK's top 13 social media agencies.

The agencies support across strategy, organic, paid, influencer, content production, TikTok Shop and more - for all sizes and shapes of brands.

Ready to find the right agency for you?

So you may be thinking, why have we included these agencies in our list?

We could have gone purely based on agency review sites or agencies that rank on the first page when you Google search, but these can often be manipulated.

That just wouldn't cut it, and we want to give you the best possible list we could create.

All of the Social Media Agencies we've put together are known to us through our personal network, or we've seen the high-quality work they do or the content they've produced for themselves.

So what should you be checking for when hiring a Social Media agency?

Industry-leading Social Case Studies

A proven track record has been clearly outlined by these agencies, and it's something you need to check into when first speaking to any agency.

If they can't share each case study with its challenge, strategy and outcome, with impressive results, it's time to move on.

True Social-first Understanding and Capabilities

In 2026, every agency says they do Social as a service, but that doesn't mean they truly understand it as a channel.

You still see agencies work, and all they can show is polished campaigns - that isn't Social.

Find agencies that are in the trenches of community-led social, can produce genuine social-first content and can elevate and extend through paid social and creators.

Deep Social Platform Relationships

The agencies listed can demonstrate they have relationships with platforms.

For example, at The Social Shepherd, they have quarterly in-person training sessions with Meta, TikTok, Pinterest, Reddit and others, whilst having constant access to betas, tests and ad credits.

Social Specialists, Not Digital Generalists.

Agencies that offer services across the full digital mix often struggle to truly deliver social as it's best. It's due to having mixed priorities, often with social not being at the top.
