For most Luton businesses, outsourced social media marketing services cost less than an in house hire. Agency retainers in the research start around £780 per month and run to £1,967 or more. A full time employee costs roughly £3,190 per month once tax, pension and tools are added.

I have reviewed a lot of marketing budgets over 16 years, and the cheaper option is not always the better one. The right choice depends on what you need done and how you will measure it. This guide gives you the numbers and the questions to ask.

What do social media marketing services cost in the UK in 2026?

Standard agency management retainers currently start at around £780 per month and reach £1,967 or more for fuller packages. Some agencies now sell flexible subscriptions instead of fixed retainers.

Many agencies still hide prices behind "call for a quote", which makes comparison hard. Publishing prices is a useful sign of confidence.

How much does an in house social media manager really cost?

A mid level hire at £30,000 costs about £38,260 per year, or roughly £3,190 per month, once employer costs are added. The salary is only around 78% of the real total.

The figures below are an illustration based on my assumptions, not market data. Replace them with your own numbers.

Check current HMRC rates before budgeting, as employer contributions can change.

Is it cheaper to hire a social media manager or outsource?

Usually outsourcing is cheaper. Against the £38,260 estimate, agency retainers of £780 to £1,967 per month (£9,360 to £23,604 per year) come out roughly £14,700 to £28,900 lower, or about 38% to 76% less.

That is my calculation from the figures above. It compares cost only, not output.

A single hire is one person with one skill set. Most social media marketing services need strategy, design, video, paid social and reporting. Getting all of that in house often means more than one salary.

Which skills does one hire not cover?

One employee rarely covers strategy, short form video, paid social, LinkedIn outreach and CRM reporting to a high standard. Something usually gets neglected.

Here is where the gaps tend to appear:

• Video production for Reels and TikTok, which needs constant volume

• Paid social management alongside organic posting

• B2B lead generation on LinkedIn

• Attribution and reporting in HubSpot or a similar CRM

Agencies spread these skills across a team. That is much of what you pay for.

What is the difference between a retainer and a subscription?

A retainer is a fixed monthly fee, often tied to a longer contract. A subscription is a flexible monthly plan you can usually change or cancel with short notice.

Subscription agencies have become more visible in the Luton and Bedfordshire market. They appeal to businesses that have been burnt by rigid 12 month lock ins.

Flexible does not always mean cheaper. Ask for the tier list in writing, and check what happens to your accounts and content if you leave.

How is AI changing the cost of social media marketing services?

AI is lowering production costs, especially for video, and leading agencies now list AI video production and LinkedIn automation as core services. Ask any agency exactly how it uses AI to reduce your bill.

Tools such as Midjourney, HeyGen and CapCut let a small team produce far more content than before. Few agencies explain how those savings reach the client, so ask directly.

Be careful with automation. Poorly run LinkedIn outreach can breach GDPR and get accounts restricted, so ask how an agency stays compliant and protects your profile.

Why do vanity metrics make both options look cheaper than they are?

Vanity metrics are numbers like likes, followers and impressions that do not show revenue. Actionable pipeline metrics are numbers like leads, opportunities and closed won sales that you can trace back to a campaign.

A cheap service that only reports likes may be the most expensive choice you make. The market is moving to full funnel reporting, where social activity is tied to revenue.

A basic closed loop setup looks like this:

1. Add tracking to your social links and pixel tracking to your site.

2. Capture source and campaign on every form submission.

3. Pass that first party data into your CRM, such as HubSpot.

4. Follow each lead to closed won and report revenue by channel.

Whoever delivers your social media marketing services, your reports should reach step 4.

When should you choose in house, and when should you outsource?

Hire in house when you need daily, brand specific presence and can fund a team around one person. Outsource when you need several skills, flexible costs or faster results.

• Choose in house if:

• You post several times daily and reply to customers in real time

• You can afford a designer, videographer and analyst around the hire

• Social media is central to how you sell

• Choose outsourced social media marketing services if:

• Your budget sits below the cost of a full time salary

• You need video, paid social and reporting together

• You want to scale up or down without redundancy costs

• Choose a hybrid if:

• An internal person owns brand voice and an agency handles production, paid social and reporting

What should you ask before signing?

Ask about pricing, contract terms, AI use and reporting. Clear written answers are the best protection against "snake oil" promises.

Frequently asked questions

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

Based on this research, standard management retainers start around £780 and reach £1,967 or more per month. Your price depends on the number of channels, video volume and reporting depth.

What is a full funnel social media strategy?

It covers awareness, consideration and conversion, then links each stage to revenue in your CRM. It goes beyond followers and engagement.

How do I track social media sales in HubSpot?

Capture the source and campaign on every form, pass the data into HubSpot, and follow each lead to closed won. Pixel tracking on your site fills in the gaps.

Does social media impact Google AI Overviews?

Nobody outside Google knows the exact weighting. Consistent, accurate profiles help AI systems recognise your business as an entity, and answer style content is easier to quote. Treat social media as a supporting signal, not a guarantee.

The bottom line

Outsourced social media marketing services usually cost less than a full time hire, and they bring a wider range of skills. An in house hire makes sense only when you need constant presence and can build a team around them.

Whichever route you choose, insist on clear pricing and reporting that reaches closed won revenue. If you are comparing quotes for social media marketing services this month, start with the table above.
