Top 13 Social Media Agencies In The UK (2025)

Finding the right Social Media Agency in the UK is a tough task.

When searching for one, you get 6,630,000,000 results.

It's no wonder it's easy to get lost in the hunt for a reliable and trusted social media agency that actually gets results for businesses.

As we all know, agencies are often known for a LOT of false promises, but when the contract gets signed, you're left with an agency that's gone quiet and isn't providing the results they once claimed they'd get you.

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

No matter what type of agency you're looking for, I've covered it.

Breaking down results-driven, creative, influencer, social media management, PR and B2B social media marketing agencies.

Ready to learn more?

Let's dive in.

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?

Case Studies

Have they done work in your industry with brands a similar size to yours?

Their Average Client Retention

The longer they work with their clients, the better! This means they provide quality work that their clients want to stick around for.

Communication

Does the agency respond to your emails quickly and have a structure in place throughout the proposal stage? This would give you a hint into their overall organisation if you were to work with them!

Time, Effort & Energy

Have they gone above and beyond to try and win your business? Is it clear that the proposal they've worked on for you is levels above everything else? Are they coming up with fresh, innovative ideas that no one else has?

But most importantly, trust your instinct when looking to bring an agency on board.

Now that you know what to look for, let's jump into the best social agencies you can choose from in the UK!
