Quick answer
  • Sitruna ranks first for UK brands that want a single London team for ads, catalogue work and logistics.
  • Optimizon, now becoming Smollan, suits established brands selling on Amazon, eBay, B&Q and Wayfair together.
  • Only one agency in this list publishes its fees: SellerVine, at $1,000 or $2,000 a month with no long-term contract.
  • Podean and Brainlabs fit enterprise brands buying media across many countries or retailers.
  • Pattern buys your stock rather than charging a retainer, so it is a different model from the rest.
  • Always confirm any partner claim in the Amazon Ads partner directory before you sign.

How did we choose and compare these UK Amazon agencies?

We shortlisted agencies with a verifiable UK base or a UK team that manage brands on amazon.co.uk, then checked each one against its own website in October 2026. We scored six things: UK presence, Amazon focus, service range, pricing transparency, stated partner status and named client results.

Disclosure

SellerVine publishes this article and appears in the list. We placed it where our own criteria put it, not at the top by default. Every competitor fact below comes from that agency's own site; where a detail was not shown, we say so rather than guess.

Here is what each criterion meant in practice:

  • UK presence: a UK office address, UK company registration or a UK contact team named on the site.
  • Amazon focus: whether Amazon is the core of the business or one channel among many.
  • Service range: advertising, listings, account health, Vendor Central and expansion from the UK into Europe or the US.
  • Pricing transparency: whether fees or a fee model are public. Most UK agencies quote after a call, which we mark as not published.
  • Partner status: what the agency itself claims. Amazon Ads runs a partner programme with verified and advanced tiers, so confirm any claim in the Amazon Ads partner directory.
  • Named results: case studies with a named brand, not anonymous percentages.

The order reflects fit for a typical UK brand selling between roughly £500,000 and £20 million a year on Amazon. An enterprise brand would likely reorder the top half.

1. Sitruna: best for UK brands that want one London team for ads, catalogue and logistics

Sitruna is a London agency on Essex Road that covers Amazon advertising, listings and creative, catalogue operations and its own 3PL warehouse. It suits UK sellers with messy catalogues or Seller Support problems who want one partner handling both the fixing and the growth work on amazon.co.uk.

Its site says the team is based in the UK and the Philippines and includes former Amazon employees, and it lists an in-house app for reporting. Each client gets a named mix of roles: a strategy lead, a client success manager, a brand manager, an advertising specialist and a copywriter. Pricing is not published.

Pros

  • Amazon is the whole business, not a side channel
  • Catalogue and flat-file fixes sit in the same team as advertising
  • Owns a warehouse and 3PL service for sellers who want fulfilment help

Cons

  • No public pricing, so budgeting needs a sales call
  • Part of the delivery team is in the Philippines, which some brands will want to discuss
  • Partner tier is not stated in the page text we checked

2. Optimizon (now Smollan Digital Commerce): best for established brands selling across several UK marketplaces

Optimizon is an Amazon-first agency founded in 2016 that also runs eBay, B&Q, Wayfair and TikTok Shop channels. It is now moving to the Smollan Digital Commerce name. It fits established UK brands that sell on more than one marketplace and want a single team behind them.

Its history page says it became the first UK agency to reach Amazon EU Platinum Partner status in 2024 and that it acquired MarketplacePower. It publishes named work, including a Tomatin whisky case study. Recruitment ads mention London office access. Fees are not published.

Pros

  • Long Amazon-only track record in the UK
  • Covers UK retail marketplaces such as B&Q that many Amazon agencies skip
  • Named case studies you can read before a call

Cons

  • Rebrand to Smollan is in progress, so check who your contract will be with
  • No public pricing
  • Better suited to larger catalogues than early-stage sellers

3. Lezzat: best for Seller and Vendor accounts expanding from the UK into Europe

Lezzat is an Amazon full-service agency with offices in Reading and Athens. It works on both Seller Central and Vendor Central and lists PPC and DSP, creative, EU expansion, account reinstatement and refund recovery. It suits UK brands planning a move into Amazon's European stores with one team.

The site states verified Amazon partner status for both Ads and the Service Provider Network. It offers a free audit to sellers above £500,000 a year in Amazon revenue. Pricing is not published.

Pros

  • Seller and Vendor experience under one roof
  • European office helps with EU launches and translation
  • Covers reinstatement and reimbursement work as well as growth

Cons

  • Fees are quoted, not listed
  • Free audit has a revenue threshold
  • Wide menu of services means you should confirm who handles your account day to day

4. SellerVine: best for brands that want published pricing and month-to-month terms

SellerVine is a full-service Amazon agency and Amazon Ads Verified Partner that manages amazon.co.uk accounts alongside the US and India. Its two published plans cost $1,000 and $2,000 a month with no long-term contract. It fits UK brands that want clear fees and VAT-aware advertising targets.

On amazon.co.uk, shoppers see VAT-inclusive prices, so SellerVine sets ACoS and TACoS targets on margin after VAT rather than on the shelf price. Its UK case study is Wide Fit Shoes, whose suspended UK account was reinstated in 48 hours. You can model your own VAT-adjusted margin with the VAT margin calculator or read more on the UK agency page.

We placed it fourth because it does not list a UK office. If face-to-face meetings in Britain matter to you, the three agencies above are a closer fit.

Pros

  • Published flat fees, with ad spend paid straight to Amazon
  • Month to month, so you can leave without a notice fight
  • UK VAT built into ad targets and reporting

Cons

  • No UK office listed on the site
  • Fees are in US dollars, so your sterling cost moves with the exchange rate
  • Covers 17 marketplaces, so ask how much of the team works on UK accounts

5. eCommerce Nurse: best for creative-led brands selling on Amazon and TikTok Shop

eCommerce Nurse is an independent agency registered in England that pairs Amazon Seller and Vendor management with TikTok Shop. Its strongest selling point is creative: design, copywriting, product photography and video. It suits UK brands whose growth problem is weak product pages or a social commerce channel they have not started.

The site describes a team of former Amazon staff and eCommerce specialists and says it supports brands across the UK, Europe, the US, Canada, the UAE and Australia. Partner status was not stated in the text we read, and pricing is not published.

Pros

  • In-house photography, video and design
  • Runs TikTok Shop alongside Amazon
  • Named client testimonials with case studies

Cons

  • No public pricing
  • Partner status not shown in the pages we checked
  • Brands needing deep PPC analytics should ask for sample reports

6. Fluid Marketplaces: best for brands moving between the UK, EU and US stores

Fluid Marketplaces is a full-service Amazon agency with offices in Manchester and Miami. It handles listings, SEO, PPC, DSP and attribution for vendors and sellers, and it runs set routes for expansion from the UK into the EU and US, and the reverse. It suits brands crossing borders.

Its FAQ says pricing depends on scope and business size, with flexible models, so no figures are published. The two offices give it working hours across both sides of the Atlantic.

Pros

  • Clear expansion playbooks in both directions
  • Covers DSP and attribution, not just search ads
  • UK and US offices

Cons

  • Pricing and minimum term are not stated publicly
  • Partner status not shown in the text we read
  • Smaller named case study library than the larger agencies

7. Podean: best for enterprise brands running Amazon in many countries

Podean is a global marketplace agency with teams in the US, Europe, Latin America, Asia, Australia and the Middle East, plus a UK and Europe contact team. It says it holds Advanced Amazon partner status in every market. It suits larger brands that want one media partner across many Amazon stores.

Its site highlights Amazon Marketing Cloud analysis, a social commerce unit for TikTok Shop, and a benchmark index built with Jungle Scout. It also says it won Amazon's top global agency award in 2023. We did not find a UK street address in the pages we read. Pricing is not published.

Pros

  • Global coverage under one contract
  • Advanced partner status claimed across markets
  • Strong media and AMC capability

Cons

  • Built for enterprise budgets rather than small sellers
  • No UK office address in the pages we checked
  • No public pricing

8. Brainlabs (including Molzi): best for brands buying retail media across several retailers

Brainlabs is a London digital media agency that absorbed Molzi, a UK Amazon specialist. Its retail media team runs Amazon sponsored ads and DSP alongside Walmart, Instacart, Best Buy and Costco, using Amazon Marketing Cloud to join the data. It suits brands that see Amazon as one part of a wider media plan.

The retail media page names a UK coffee brand result on Amazon. Brainlabs also runs search, social and programmatic, which helps brands that want one agency across paid channels. Pricing is not published.

Pros

  • London head office and a large media team
  • Connects sponsored ads and DSP through AMC
  • Can run Amazon next to Google and social

Cons

  • Amazon is one service among many
  • Less focus on catalogue fixes and account health
  • No public pricing

9. Marketplace amp: best for FMCG brands on Amazon, eBay and Ocado

Marketplace amp is a Cambridge agency that specialises in fast-moving consumer goods: food and drink, health and hygiene, pet care, and home and garden. It runs Amazon account management, advertising, DSP and content, and also covers eBay and Ocado. It suits grocery and household brands selling through UK online retailers.

It describes itself as part of the Optimizon Group, so the group behind entry 2 also owns it. Pricing is not published.

Pros

  • Category focus on FMCG
  • Covers Ocado, which few Amazon agencies touch
  • Seller and Vendor support

Cons

  • Narrow fit outside FMCG
  • Shares ownership with Optimizon, so compare the two before choosing
  • No public pricing

10. Pattern: best for brands that want a partner to buy stock and run the channel

Pattern has a London office on Wardour Street and works differently from a fee-based agency. Under its 3P model it can buy your inventory and sell it on Amazon itself, while managing advertising, content and brand protection. It suits brands that would rather sell wholesale than run their own Seller Central account.

Its UK site also covers marketplace prep, global expansion and recovery of Amazon losses. Because the model is commercial rather than a retainer, pricing is not published and terms vary by brand.

Pros

  • You hand over most day-to-day channel work
  • Large technology and data platform
  • Strong brand protection focus

Cons

  • You give up some control of pricing and the customer relationship
  • Not a like-for-like comparison with retainer agencies
  • Terms are negotiated, so compare margins carefully

How should you choose an Amazon agency in the UK?

Start with the problem you need solved, not the biggest name. Shortlist three agencies that fit that problem, ask each for a written proposal, and compare fees, contract terms, who does the work and how results are reported after VAT. Then call a current UK client of each.

Five questions to ask on the first call

Who will manage my account each week, and where are they based? What is the notice period? Do you take a percentage of ad spend or sales? Do you report ACoS and TACoS on prices after VAT? Can I speak to a UK client with a similar catalogue?

Match the agency type to your situation:

  • Catalogue or account health problems: an operations-heavy team such as Sitruna or Lezzat.
  • Several UK marketplaces: Optimizon or Marketplace amp.
  • Clear fees and short commitment: SellerVine.
  • Creative and TikTok Shop: eCommerce Nurse.
  • Global or retail media scale: Podean or Brainlabs.

Frequently Asked Questions

What is the best Amazon agency in the UK?

There is no single best choice. On our criteria, Sitruna suits brands wanting one London team for ads, catalogue and logistics, Optimizon suits multi-marketplace brands, and Lezzat suits Seller and Vendor accounts expanding into Europe. SellerVine fits brands that want published fees. Pick the agency that matches your main problem and budget.

How much does an Amazon agency cost in the UK?

Most UK agencies do not publish fees and quote after an audit. Among the 10 we checked, only SellerVine lists prices, at $1,000 or $2,000 a month. Others typically charge a monthly retainer, a share of ad spend or a mix. Ask for the full fee model, including any minimum term, in writing before you sign.

Do I need a UK-based Amazon agency to sell on amazon.co.uk?

Not strictly. What matters is that the team understands UK VAT, EPR and product rules, British search terms and the UK retail calendar. A UK office helps if you want in-person meetings or overlapping hours. Ask any agency how many of its people work on UK accounts and how it reports results after VAT.

What does Amazon Ads Verified or Advanced Partner mean?

These are tiers in the Amazon Ads Partner Network. Agencies earn them by showing advertising expertise, engagement with Amazon Ads and certified staff, with advanced being the higher tier. The status shows competence with Amazon's ad tools, not guaranteed results. You can check any claim in the Amazon Ads partner directory.

Should a UK agency charge a percentage of ad spend?

It is common but has a drawback: the agency earns more when you spend more, whether or not the extra spend is profitable. Flat fees remove that link but may not scale with workload. Whichever model you choose, ask how the agency decides when to cut spend and how it reports profit after VAT.

How long should an Amazon agency contract be in the UK?

Many agencies ask for three to twelve months, while some work month to month. Shorter notice protects you if results stall. Look for a clear exit clause, confirmation that you own your Seller Central account and ad data, and a handover process. Our contract guide lists the clauses worth checking before signing.

Can a UK Amazon agency help me expand into Europe?

Yes, several in this list run UK to EU launches, including Lezzat, Fluid Marketplaces and Optimizon. Expansion needs separate VAT registrations, translated listings, local keyword research and EU product compliance. Ask the agency which European stores it already manages and whether it uses native speakers for listings.

Want UK fees you can see before a call?

SellerVine lists its plans publicly and works month to month. Book a short call and we will review your amazon.co.uk ads and margins after VAT.
