What services does a social media agency provide?

A social media agency offers strategy development, content creation, community management, paid social advertising, influencer marketing, analytics, and reporting. The best agencies also cover UGC, short-form video production, social listening, and campaign creative — adapting their service mix to each platform and audience.

How much does a social media agency cost in the UK?

UK social media agency retainers typically range from £3,000 to £20,000+ per month, depending on the size of the brand and what's included. A retainer covering organic content management for two platforms sits at the lower end. Full-service packages — combining paid social across Meta and TikTok, influencer campaign management, content production, and detailed monthly reporting — sit towards the higher end. Paid social ad spend is always budgeted separately on top of the agency retainer fee.

What is the difference between a social media manager and a social media agency?

A social media manager is a single person — employed in-house or working freelance — who handles your social channels. A social media agency is a full team: strategists, content creators, designers, paid media specialists, and account managers working together. Agencies bring broader skills, industry knowledge, and production capacity that a solo hire rarely matches, and can scale up for campaigns or product launches without missing a beat.

When should I hire a social media agency?

Consider hiring a social media agency when your in-house team is struggling to keep pace with content demands, your paid social isn't converting, you're launching a new brand or product, or you want a strategy built around data rather than guesswork. Agencies are particularly valuable if you need high-quality creative content at scale — producing Reels, carousels, UGC, and paid assets consistently is a full-time operation.

What results should I expect from a social media agency?

In the first 90 days, expect a clearer content strategy, improved posting consistency, and early data on what's working. Meaningful growth in reach, engagement, and conversions typically builds over 3–6 months. A good agency sets clear KPIs from day one and reports against them regularly — not just vanity metrics, but numbers tied to your business goals.

How long does it take to see results from a social media agency?

Organic social results build meaningfully over 3–6 months. Paid social campaigns can show results within weeks, but need at least 4–6 weeks of the platform's learning phase before being properly optimised. Be wary of agencies promising overnight growth — sustainable social success takes consistent, strategic effort across content, community, and paid channels.

What platforms do social media agencies manage?

Most agencies manage the major platforms: TikTok, Instagram, LinkedIn, Facebook, YouTube, X, and Pinterest. Some also specialise in Snapchat, Reddit, Discord, or emerging channels based on audience needs. The best agencies won't push you onto every platform — they'll focus on the two or three where your audience actually spends time.

Should I hire an agency or manage social media in-house?

This depends on your budget, expertise, and available resources. An in-house team provides brand consistency and full-time focus, but a social media agency offers specialised expertise, scalability, and access to advanced tools and production capacity. Many brands opt for a hybrid approach: agency for strategy and high-production creative, in-house for community management and day-to-day posting.

Can a social media agency help with crisis management?

Yes. A strong agency will have crisis management protocols in place to monitor brand sentiment, respond to negative feedback, and implement damage control strategies quickly. Agencies use social listening tools to track mentions and sentiment in real-time, helping brands stay ahead of issues before they escalate.

What's the difference between a social media agency and a digital marketing agency?

A social media agency focuses on organic and paid social — content creation, community management, influencer campaigns, and platform-native strategy. A digital marketing agency typically covers a broader remit: SEO, PPC, email marketing, website development, and overall brand strategy. Brands looking specifically for social growth and content at scale are usually better served by a dedicated social media agency.

What Does a Social Media Agency Do?

In today's digital-first world, social media is more than a channel — it's a cultural hub where brands must compete for attention. With over 5.2 billion social media users globally, being present isn't enough. To thrive, businesses need a powerhouse social media agency that can craft data-driven strategies and deliver measurable results.

But what exactly does a social media agency do, and how do you choose the right one? This guide covers their key services, typical UK costs, and exactly what to look for when selecting an agency for your brand.

What Is a Social Media Agency?

A social media marketing agency is a specialist company that manages your brand's online presence across platforms like Instagram, TikTok, LinkedIn, Facebook, X, and Snapchat. Services include content creation, digital design, paid advertising, influencer partnerships, community management, social listening, and data-driven strategy — everything needed to grow and sustain a strong social presence.

Partnering with an agency brings expert knowledge and a strategic, scalable approach your in-house team may not have bandwidth for. Outsourcing social media management can significantly improve engagement rates and ROI. Businesses gain access to data-driven insights, creative execution, and trend-driven strategies that maximise engagement and strengthen brand presence.

In this article, we deep dive into how to evaluate agencies — considering factors like niche expertise, pricing models, and scalability — which play a critical role in determining the right fit.

What Is a Social Media Management Agency?

A social media management agency handles the ongoing, day-to-day operation of your brand's social channels. Where a general social media agency might run campaigns, a social media management agency keeps things running consistently between them — publishing, community management, reporting, and strategic optimisation, month in, month out.

Social media management vs. social media marketing: what's the difference?

The terms are often used interchangeably, but there's a meaningful distinction for brands planning their budgets:

Social media management: always-on work. Content calendars, scheduling, publishing, responding to comments and DMs, monitoring mentions, monthly reporting. The engine that keeps your channels alive.
Social media marketing: campaign-driven work. A product launch, a seasonal push, an influencer activation, a paid media burst. Time-bounded with a specific objective.

Most brands need both. A good social media management agency will build a management retainer that flexes for campaign moments — so the always-on work doesn't stop when you're mid-launch.

What does a social media management agency do day-to-day?

The day-to-day scope of a social media management agency typically includes:

Content calendar planning — mapping posts, stories, reels, and threads weeks in advance
Content creation — copywriting, design, short-form video, and UGC coordination
Scheduling and publishing — across Instagram, TikTok, LinkedIn, X, and wherever your audience lives
Community management — responding to comments, DMs, and mentions in your brand voice
Social listening — monitoring brand mentions, competitors, and trending conversations
Monthly reporting — reach, engagement, follower growth, link clicks, and the metrics that actually matter to your business
Strategy reviews — quarterly reviews of what's working, what's not, and where to double down

How much does a social media management agency cost in the UK?

Social media management retainers in the UK typically run from £2,000–£5,000 per month for a focused brand (one or two channels, regular content, monthly reporting) up to £10,000–£20,000+ per month for full-service management across multiple channels with paid media and influencer work included.
