Handing your social media accounts to someone else is a big decision. Your brand’s voice, your customers’ first impressions and a fair chunk of your marketing budget all end up in another team’s hands. So how to choose a social media agency is a question worth taking your time over, and this guide is written to help you do exactly that, whether you are a small business owner hiring for the first time or a marketing manager replacing an agency that has not worked out.

We should be upfront: Delivered Social is a social media agency, so we have an interest here. We have tried to write the guide we would want a buyer to read, one that would help you pick the right agency even if that is not us. You will not find any digs at other agencies below. Most agencies are decent, and the real problem is usually a poor match between what you need and what they are good at.

First, decide whether you need an agency at all

Before you speak to anyone, it is worth asking whether outsourcing is the right move. An agency is not automatically better than doing it yourself or hiring someone in-house. It depends on your time, budget and goals.

When in-house works well

Hiring an employee suits you if social media is central to how you win customers and you can give someone enough to do. An in-house person knows your products, your people and your story at close range. They can film something at short notice and reply to a comment within minutes. The trade-offs are cost (salary, tax, pension, software, training, holiday cover) and the fact that one person rarely covers strategy, design, video, paid advertising and reporting equally well.

When an agency works well

An agency tends to make sense when you want a spread of skills without hiring several people, when you need cover for holidays and sickness, or when you want someone who has seen what works across many different businesses. It can also be easier to scale up or down. The trade-offs are that nobody outside your business will ever know it quite as well as you do, and you need to put some time into briefing and approvals.

The middle route

Plenty of businesses blend the two: an in-house person handles day-to-day posting and customer replies, while an agency supports with strategy, video, paid campaigns or reporting.

Get clear on your goals before you start looking

The most common reason agency relationships fail is a fuzzy brief. If you cannot say what success looks like, nobody can deliver it. Write down, in plain English, what you want social media to do for the business in the next 6 to 12 months.

• More enquiries or sales from social media?
• Better awareness in a local area?
• Recruitment, so you attract staff?
• Looking more credible than your competitors?
• Saving your own time?

Pick one or two priorities rather than all of them. Then work out roughly what you can spend each month, and be honest about it. Agencies price very differently, and sharing a realistic budget early saves everyone a lot of wasted calls. If you are not sure where your accounts stand today, a simple review helps you brief far better, and our social media audit template walks you through one in an afternoon.

How to choose a social media agency: what to compare

Once you have a shortlist of three or four, compare them on the same things. Here is what we would look at.

Relevant experience, not just big names

Ask to see work for businesses of a similar size or in a similar sector. A logo wall looks impressive, but what matters is whether they have solved a problem like yours. If you are a local service business, experience with local businesses is worth more than a famous consumer brand. Ask what the client wanted, what the agency did and what changed as a result.

The people who will actually do the work

In some agencies the people who pitch are not the people who run your account. That is not a crime, but you should know. Ask who will be your day-to-day contact, how many accounts they look after, who writes the content, who designs it and who handles replies. Meet them if you can.

How they build a strategy

Good agencies start by asking questions: who your customers are, what you sell, what has worked before. Be cautious of any proposal that looks like it could be sent to any business with the name swapped. Ask how they choose platforms, how they decide what to post and how they test and adjust.

Content you can see before it goes live

Ask how approvals work. Most agencies share a monthly content calendar for sign-off, then post once you are happy. Check how much notice you get, how many rounds of edits are included and what happens when something time-sensitive comes up. If you want to see what a calendar might look like, our content calendar template is a useful reference to bring to the conversation.

Channel and format skills

Short video is a big part of social media now. If you want it, ask who films and edits it, and whether it is included in the price. Some agencies are stronger on design and copy, others on video. Neither is wrong if it matches your needs.

Questions worth asking on the call

You do not need to be a marketing expert to run a good meeting. These questions do most of the work for you, and they are the heart of any sensible approach to how to choose a social media agency.

1. Who will manage our account day to day, and how many other clients do they look after?
2. What would you do in our first 90 days?
3. How will you learn our brand voice, and who signs off posts?
4. Which numbers will you report on, and how often?
5. What is included in the monthly fee, and what costs extra (ad spend, filming, design, stock images, tools)?
6. Do we own the accounts, content and any ad accounts you set up?
7. What happens if we want to leave?
8. Can we speak to a current client?

Pay attention to how they answer as much as to what they say. Clear, specific answers and a willingness to say “that depends, and here is why” are good signs. Vague answers, or an eagerness to move on from a question, are worth noting.

Red flags to watch for

No list of red flags is a perfect test, but these are the things we would pause on if we were the buyer.

• Guaranteed results. Nobody controls the algorithms, so promises of a set number of followers, sales or viral posts should make you cautious. Good agencies talk about targets and what they will do to reach them, not guarantees.
• Talk of buying followers or likes. Paid fake engagement breaks platform rules and does not bring customers. If an agency suggests it, walk away. Our guide to follower growth service red flags explains why.
• No questions about your business. If the pitch never asks what you sell or who buys, the plan is probably generic.
• Vague pricing. You should be able to see what you get for the money in writing.
• Pressure to sign today. A good proposal will still be good next week.
• Reporting that is all vanity. Reports full of impressions but never mentioning enquiries, clicks or sales can hide a lack of progress.
• Unclear account ownership. If the agency would own your pages or ad accounts, you could lose them if you part ways.

A single red flag does not always mean a bad agency. If something concerns you, ask directly and see how they respond.

Contracts and pricing: what to check

This is general information, not legal advice. If a contract is large or complex, it is sensible to have a solicitor read it.

Length and notice

Agency contracts are commonly rolling monthly or fixed for a period such as six or twelve months. Neither is wrong. A longer term can mean a better rate, but it matters that you know how to exit if things go badly. Check the notice period and whether there are any early termination fees.

What is included

Look for a clear list of deliverables: number of posts, platforms, videos, stories, community management hours, reporting and meetings. Check how ad spend is handled. It is usually paid by you directly to the platform, or passed through by the agency, and it should be separate from the management fee so you can see both.

Ownership and access

Make sure you stay the owner of your social profiles, your ad accounts, your content and any logins. You should be added as an admin, and the agency should work through shared access rather than holding the only set of passwords. Also check who owns the content the agency creates for you, such as photos, video and designs, and whether you can keep using it after the contract ends.

Data and legal basics

If the agency will handle customer data, for example from lead forms or direct messages, ask how it is stored and protected, since UK data protection law applies. If they will work with influencers, the UK advertising regulator expects paid and promotional content to be clearly labelled, and the ASA influencer guide is the place to look. A responsible agency will already know it.

Checking the company itself

It takes two minutes to look up any UK limited company on Companies House, where you can see its registered address, directors and filing history. It does not tell you whether the work is good, but it confirms who you are dealing with.

Reporting: what good looks like

You should never have to wonder what you are paying for. Ask to see a sample report before you sign. A useful one covers:

• The goals you agreed and whether you are moving towards them.
• Reach and engagement, with context from the previous period.
• Actions that matter to the business, such as website visits, enquiries, calls, bookings or sales.
• What worked, what did not and what will change next month.

It also helps to know what normal looks like. Our social media benchmarks for the UK give you a sense of whether an engagement rate is strong or weak, so you can judge results sensibly.

Agree how often you will meet. Monthly reports with a short call each quarter suit many small businesses. And remember that social media usually takes a few months to show a clear trend, so judge on direction over time and not a single week.

Setting up a good start

When you have narrowed it down, a sensible agency relationship starts with an onboarding period. Expect questions about your brand, customers and past results, a review of your accounts, an agreed plan and a first content calendar. Put time in your diary to be available for the first few weeks, as the quality of what you get out depends on what you put in.

A clear review point after a few months is sensible too.

When you are ready to decide, score each agency against your goals, budget, people and communication. Gut feel counts too: if you enjoyed the conversations and felt listened to, that matters, because you will talk often. Know your goals, ask good questions, read the contract and insist on honest reporting, and the decision becomes much easier.

Frequently asked questions

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

Prices vary widely depending on how many platforms, how much video and design is involved and how much account management you need. We have not quoted a figure because any single number would mislead. Ask for quotes from three agencies against the same brief and compare what each includes.

How long before I see results?

It depends on your starting point and goals, but social media is rarely an overnight fix. Many businesses look for a clear trend over three to six months. Ask each agency what they would expect to see and when, and treat very short promises with caution.

Should I choose a local agency?

Not necessarily, as plenty of agencies work well remotely. A local agency can be useful if you want face-to-face meetings, local knowledge or someone who can visit to film. Decide whether that matters to you.

Can I see my own accounts and data?

Yes, and you should insist on it. You should be an admin on your own pages and have access to analytics and ad accounts at all times.

What if it is not working?

Raise it early and in writing. Good agencies would rather adjust than lose a client. If it still does not improve, use the notice period in your contract, and make sure you retain your accounts and content on the way out.

Need a hand choosing?

The short version of how to choose a social media agency is to be clear on what you want, compare like with like and trust the people who answer plainly. If you would like a straight conversation about what you need, we are happy to talk it through, even if the answer turns out to be doing more in-house or choosing someone else.
