The short answer: There is no standard price. Most UK influencer agencies charge a monthly retainer, a fixed project fee, a percentage of the creator fees or paid media they manage, or a base fee with a performance element, and very few publish rates. On top of the agency fee you normally pay for creators, product and shipping, paid media and usage rights. Judge any quote on two numbers: cost per thousand people reached and cost per acquired customer, both including the agency fee.
As of September 2026. Augmentum Media does not publish its own prices; the ranges below are third-party figures and are attributed to their source.
How do influencer marketing agencies charge?
Four models cover almost every agency, and many combine two of them.
Model | How it works | Suits | Watch for |
|---|---|---|---|
Monthly retainer | Fixed fee for an agreed scope, such as programme management, creator sourcing and reporting | Always-on programmes | Vague scope that shrinks over time |
Project fee | One price for a defined campaign | Launches and one-off campaigns | Nothing compounds once it ends |
Percentage of spend | A share of the creator fees or paid media the agency manages | Paid creator and whitelisting campaigns | An incentive to spend more rather than better |
Performance-linked | Base fee plus bonus against agreed results, or payment per action | Programmes with clean tracking | Arguments over attribution |
Few agencies publish rates, so any range is indicative. Favikon, an influencer data platform, publishes typical US figures: retainers of roughly $3,000 to $20,000 or more a month, commission of 10 to 30 percent of influencer fees or ad spend, small micro-influencer campaigns of around $5,000 to $15,000, and hourly rates of $100 to $300 or more. Those are US dollar estimates rather than UK quotes, but UK agencies use the same structures.
What costs sit on top of the agency fee?
The agency fee is often the smaller part of the budget. Ask every agency which of these are included, because two quotes that look far apart can be the same price once they are:
Creator fees. What creators charge for posts, from product-only for nano creators to thousands per post for larger names. Our guide to UK influencer pricing covers the bands.
Product and fulfilment. The cost of goods sent in a seeding programme, plus packaging and shipping.
Paid media. Budget behind creator content in partnership or Spark ads.
Usage rights and whitelisting. Payment for the right to run creator content as ads. See what to pay for whitelisting.
Software and networks. Discovery platforms, affiliate networks and tracking tools.
Affiliate commission. Paid on sales, so it scales with results rather than sitting in the fixed budget.

How do you tell if an agency is worth what it costs?
Compare what each pound bought, with the agency fee included. Two numbers do most of the work.
Cost per thousand people reached (CPM). It lets you compare an influencer programme with paid social directly. Published Augmentum Media programmes show how widely it varies by model: Lululemon reached more than 7.1 million impressions at a £2.49 CPM using nano and micro creators with no influencer fees, Fussy reached more than 19 million at £3.27, and a mid-tier paid campaign for Fabletics came in at £16.34, which was 18 percent better than its target.
Cost per acquired customer, including fees. This is the number that decides whether the programme pays. Fussy's programme acquired more than 11,500 new customers at a customer acquisition cost under £13.96 including fees, or £5.52 excluding them. The gap between those two figures is exactly why fees belong inside the calculation rather than beside it.
An agency can also save more than it costs on the other lines. On the Fabletics campaign, Augmentum Media negotiated an average 30 to 40 percent discount on creator fees. If you want to put a value on reach itself, our guide to earned media value shows the calculation and its limits.
Is an agency cheaper than running influencer marketing in house?
In house is usually cheaper once a programme is designed and running, and slower to get there. An in-house hire costs a salary plus software, and needs time to build creator relationships, briefing processes and tracking before results arrive.
An agency is worth the premium when you need the creator pool and the process now rather than in a year, when the programme is bigger than one person's job, or when the team's time is better spent elsewhere. A common middle route is to use an agency to design and prove the programme, then bring it in house with the process documented. Augmentum Media offers research and strategy with a handover-ready programme for that reason.
What should you ask for in an agency quote?
Exactly which of the cost lines above are inside the fee.
The minimum term and notice period. Creator programmes need at least a quarter to read properly.
The CPM and cost per acquired customer, including fees, on a comparable programme.
Who owns the creators, content rights, ad accounts and affiliate network if you part ways.
How the fee changes as the programme grows, so success does not become a surprise invoice.

Frequently asked questions
How much does an influencer marketing agency cost per month in the UK?
Few UK agencies publish rates. Retainers depend on scope and programme size; third-party US estimates from Favikon put typical retainers at roughly $3,000 to $20,000 or more a month, with creator fees, product and media on top.
What percentage do influencer agencies take?
Where an agency charges a share of spend, Favikon puts the typical range at 10 to 30 percent of influencer fees or ad spend. Always confirm what the percentage is calculated on.
Do influencer agencies charge creators or brands?
Influencer marketing agencies are paid by brands. Talent management agencies represent creators and usually take a commission from the creator's fee. Some firms do both, so ask which side they represent on your campaign.
Is a retainer or a project fee better?
A retainer suits always-on programmes where relationships and content compound. A project fee suits a single launch. Seeding and affiliate programmes usually need a retainer because their value builds over months.
What is a good cost per acquired customer from influencer marketing?
One below your target customer acquisition cost for other channels, calculated including every fee. There is no universal benchmark because margins and lifetime value differ by brand.
Can you pay an influencer agency on results only?
Some agencies offer performance-linked fees, usually as a base fee plus a bonus rather than results only, because creator campaigns are hard to attribute perfectly. Affiliate commission is the part of a programme that is genuinely paid on results.
Why don't influencer agencies publish their prices?
Because the cost depends heavily on scope, creator tier, product and whether paid media is included, so a published price would rarely match the quote a brand actually receives.
What is the cheapest way to start with influencer marketing?
Product seeding to nano and micro creators, which costs product and time rather than creator fees. Our guide to influencer seeding explains how to run it.
