David BalanCo-founder, Horison Marketing6 min read
Disclosure: this comparison is published by Horison Marketing, which is one of the eight agencies listed. We list ourselves first because it is our site, so judge us on the same five checks as everyone else. Every fact about other agencies comes from their own websites as of 29 October 2026; tell us if anything has changed and we will update it.
The short answer
If you sell on Amazon.co.uk, the agency that fits you depends on what you need most:
- One team for SEO, PPC, creatives and catalogue problems: Horison Marketing, Sitruna, Lezzat.
- Vendor Central and retail-wide work: Optimizon (now Smollan), SalesDuo, Sitruna.
- Published, fixed starting price: Chris Turton Ecommerce, Olifant Digital.
- A category specialist (food, drink, supplements): Amazowl.
How we compared them: five checks
We used five yes/no checks that any brand can repeat in an afternoon. None of them depends on an agency’s own marketing language.
| Check | Clears the bar | Fails it |
|---|---|---|
| 1. UK presence | A UK company and a team that works UK hours | A UK phone number with no UK team |
| 2. Full scope in one team | SEO, PPC, creatives and account health under one plan | Ads only, with listings outsourced |
| 3. Amazon partner status | A stated status you can confirm in Amazon’s partner directory | Badges with no directory listing |
| 4. Published proof | Case studies with numbers, timeframes and marketplaces | “Great results” with no figures |
| 5. Pricing published | A starting fee or a clear pricing model on the site | “Contact us” only |

How to check any Amazon agency yourself
- Look the agency up in Amazon’s own partner directory. A badge on a website is not proof; a directory listing is.
- Ask for two Amazon.co.uk case studies in your category, with the starting point, timeframe and TACoS, not just revenue growth.
- Ask how they set ACoS targets. The answer should start from your margin after VAT, FBA fees and returns.
- Check reviews on more than one site, such as Trustpilot, Clutch and Google, and read the negative ones.
- Ask who will work on your account, where they are based and how many accounts each person manages.
- Read the contract for the notice period, any performance fees and who owns the account, ads and creative files. Our contract red flags checklist covers all nine things to check.
If you want to see how Horison answers these, book a free discovery call. We’ll tell you honestly whether we’re the right fit, and if we’re not, which type of agency is.

Frequently Asked Questions
Which is the best Amazon agency in the UK?
There is no single best agency for every brand. For one team running SEO, PPC, creatives and catalogue fixes, look at full-service agencies such as Horison Marketing or Sitruna. For Vendor Central, look for agencies that publish vendor work, such as SalesDuo or Optimizon. If published pricing matters most, Chris Turton Ecommerce and Olifant Digital list starting fees. Check any agency against the five checks in this article.
Do I need a UK-based agency to sell on Amazon.co.uk?
Not strictly, but it helps. A UK team knows British search terms and spelling, UK category rules, VAT-inclusive pricing and UK seasonal peaks, and works in your time zone. Many agencies also run part of their team offshore, so ask where the people on your account actually work.
How do I check an agency's Amazon partner status?
Search for the agency in Amazon's own Amazon Ads Partner Directory (advertising.amazon.com/partners/directory). A listing there confirms its status. Badges on an agency's website are not proof on their own.
How much does an Amazon agency cost in the UK?
Published starting fees for UK-facing agencies run from about £1,500 to £2,500 a month, and full-service retainers for larger accounts are higher. Most agencies quote individually based on products, marketplaces, ad spend and services. See our guide to Amazon agency pricing models for the details.
Are there Amazon agencies in London?
Yes. Sitruna and Olifant Digital list London offices, and many UK agencies, including Horison Marketing, work with London brands remotely through video calls and shared dashboards.
What should be in an Amazon agency contract?
Check the notice period, who owns the Seller Central account, ad account and creative files, what is included in the monthly fee, how performance is reported, and whether there is any performance fee. You should always keep ownership of your account and data.
