Top 10 Shopify Agencies UK 2026
1. eComOne: Lincoln | Ecommerce SEO and Shopify Growth
Location: Lincoln, UK (working with clients nationally and internationally)
Best for: Ecommerce brands that want to grow organic revenue, migrate to Shopify or build a long-term growth engine combining SEO, CRO and email.
Key services: Shopify SEO, technical SEO, Shopify migrations, CRO, Klaviyo email marketing, paid media, Shopify growth retainers, ecommerce strategy.
We were founded by Richard Hill, who scaled his own ecommerce business to multi-million pound revenue before starting the agency. That background shapes everything we do. Our entire approach is built around what actually moves the needle for online retailers: non-branded traffic, product page visibility, conversion and customer retention.
What we actually do well:
Technical SEO is one of our strongest capabilities. Keiran, our Technical SEO Specialist, brings deep expertise to the platform-specific challenges Shopify stores face. Crawl budget issues, canonical tag problems from Shopify’s default URL structure, product schema, Core Web Vitals, structured data for Google Shopping. For brands that have invested in Shopify development but aren’t seeing organic growth, our technical SEO audits consistently find the root cause.
Shopify migrations are a core part of what we do. Whether you’re moving from Magento, WooCommerce, BigCommerce or a bespoke legacy platform, we manage the migration with SEO continuity front and centre. That means preserving URL structures wherever possible, building thorough redirect maps and monitoring organic performance closely after launch. Too many Shopify migrations are handled by development agencies that treat SEO as an afterthought. We don’t.
On the retention side, our Klaviyo email marketing goes well beyond flow setup. We build revenue-focused email programmes: post-purchase sequences, abandoned basket recovery, win-back campaigns and segmented promotional sends. Everything ties back to revenue contribution, not open rates. That integration of SEO, paid media and email into a single growth retainer is something a lot of ecommerce brands tell us they’ve been looking for. One agency, one strategy, one set of goals.
We’re not trying to be everything to everyone. We’re ecommerce specialists, and that focus shows in our work. If you’re on Shopify or planning to migrate and you want an agency that thinks about revenue first and rankings second, come and speak to us.
2. Swanky: Exeter | Shopify Plus Design and Development
Location: Exeter, UK
Best for: Mid-market and enterprise brands looking for premium Shopify Plus design, development and international growth.
Key services: Shopify Plus development, UX design, internationalisation, subscriptions, headless commerce, CRO, Klaviyo.
Swanky are one of the most established Shopify Plus agencies in the UK. They’ve built a strong reputation across fashion, health and lifestyle ecommerce for UX-led Shopify Plus builds that balance creative ambition with commercial performance. Their internationalisation capability is a genuine strength: if you’re scaling into European or North American markets, they understand the technical and operational complexity that involves.
CRO is integrated into their development work rather than bolted on. That matters. Optimisation insights get actioned quickly, not left in a backlog. And their Klaviyo expertise sits alongside their development capability well for brands building post-purchase retention alongside a new store.
3. Eastside Co: London | Full-Service Shopify Plus
Location: London, UK
Best for: Fast-growing UK ecommerce brands wanting end-to-end Shopify Plus support, from development through to marketing.
Key services: Shopify Plus development, SEO, CRO, paid media, email marketing, app integrations, ERP and PIM integrations.
Eastside Co are one of the largest Shopify agencies in the UK. With a big team across development, design, SEO and performance marketing, they can support ambitious ecommerce brands across the full lifecycle. Their London base gives them strong access to the fashion, beauty and consumer goods sectors that dominate UK ecommerce.
Systems integration is a real strength. For brands running complex operations connecting Shopify Plus to an ERP, PIM or warehouse management system, the technical team has the depth to manage integrations that would stretch a smaller agency. SEO and performance marketing both run in-house, which cuts the coordination friction that comes from managing multiple suppliers.
4. We Make Websites: London | Premium Shopify Plus
Location: London, UK
Best for: Premium and luxury ecommerce brands seeking high-quality Shopify Plus development and international growth.
Key services: Shopify Plus development, UX, internationalisation, headless Shopify, migrations, subscriptions.
We Make Websites have an internationally recognised portfolio across premium consumer brands in fashion, home and lifestyle. Their headless Shopify work is worth understanding. For brands considering a decoupled front end to get more flexibility over performance and UX, they’ve delivered headless builds that don’t sacrifice conversion to get there.
They’re particularly strong on internationalisation via Shopify Markets. Currency, tax handling, localised content, logistics: for UK brands scaling into the EU, USA or APAC, they know what that complexity looks like in practice.
5. Underwaterpistol: London | Shopify Plus Agency
Location: London, UK
Best for: Fashion, beauty and lifestyle brands looking for creative Shopify Plus development with a strong UX focus.
Key services: Shopify Plus development, UX design, CRO, theme development, Shopify migrations.
Underwaterpistol have been building Shopify stores for over a decade. For brands in fashion, beauty and lifestyle, where the visual expression of a brand is as commercially important as the technical architecture, they’re a strong option. Their theme development is thorough. They build bespoke Shopify experiences rather than adapting off-the-shelf themes.
CRO adds the commercial rigour. They approach UX improvements through data and user behaviour analysis, which keeps conversion at the centre of the creative process. Not a finishing concern.
6. Cake Agency: Manchester | Shopify and Performance Marketing
Location: Manchester, UK
Best for: Growing UK ecommerce brands combining Shopify development with performance marketing.
Key services: Shopify development, Shopify Plus, paid media, email marketing, CRO, UX.
Cake Agency bring Shopify development and performance marketing together under one roof. For brands that don’t want to split acquisition and development across multiple agencies, that’s a genuine advantage. Based in Manchester, they offer strong access for northern ecommerce brands and have built a solid reputation for commercially grounded work.
Their paid media covers Google Shopping, Google Ads, Meta and TikTok. Combined with Shopify development built with marketing performance in mind, it’s a coherent proposition for mid-market ecommerce brands scaling across multiple acquisition channels.
7. Fourmeta: London | Shopify Plus Migration and Development
Location: London, UK
Best for: Brands migrating from legacy platforms to Shopify Plus, or mid-market brands needing technical Shopify development.
Key services: Shopify Plus development, migrations from Magento, WooCommerce and BigCommerce, ERP integrations, subscriptions, headless commerce.
Fourmeta have built a strong reputation for technically complex Shopify Plus work, particularly platform migrations. If you’re moving a large, data-heavy ecommerce operation from Magento or a custom platform to Shopify Plus, they have the technical depth to manage it. Data migration, redirect handling, third-party integrations, performance validation after launch.
Their subscription commerce capability is worth noting too. Shopify subscription ecommerce has specific technical and UX requirements, and Fourmeta have genuine experience implementing models that work commercially and operationally.
8. blubolt: Bath | Bespoke Shopify Plus Development
Location: Bath, UK
Best for: UK ecommerce brands looking for technically precise Shopify Plus development with a focus on performance and UX.
Key services: Shopify Plus development, bespoke theme builds, CRO, UX, technical integrations.
blubolt are a well-regarded Shopify Plus agency working with UK and international brands across fashion, health and homeware. Their approach to development is methodical. They don’t rush builds, which tends to produce more stable, better-performing stores at launch.
Their Core Web Vitals work stands out. In an environment where page performance directly affects both paid media Quality Scores and organic rankings, having a Shopify build that performs well on mobile isn’t optional in competitive ecommerce.
9. Juno Ecommerce: Bristol | Shopify Growth and Development
Location: Bristol, UK
Best for: Growing UK ecommerce brands wanting a commercially focused Shopify agency covering development, SEO and CRO.
Key services: Shopify development, Shopify Plus, SEO, CRO, email marketing, analytics, UX.
Juno Ecommerce have built a strong reputation as a commercially minded Shopify agency. Their analytics capability stands out. They take a data-informed approach to both development decisions and ongoing CRO, so the work has a clear commercial rationale rather than being driven by preference or convention.
SEO is integrated into their wider service rather than treated as a separate offering. For brands that understand organic search as a long-term growth channel, that integration matters. Based in Bristol, they work with UK and international ecommerce brands across a wide range of categories.
10. StudioHawk: UK and Australia | Specialist Shopify SEO
Location: UK and Australia
Best for: Ecommerce brands that prioritise organic search and want dedicated Shopify SEO expertise.
Key services: Shopify SEO, technical SEO, content strategy, link building, SEO audits, keyword research.
StudioHawk are one of the more highly regarded SEO-specialist agencies in the Shopify ecosystem. Their focus is narrower than a full-service agency. They don’t build stores or manage paid media. But for brands that specifically want dedicated SEO attention on their Shopify store, they bring real depth. Their approach to technical SEO for Shopify is rigorous, and their content-driven organic growth work has produced measurable results.
If you’re already working with a development agency for your build and a performance marketing agency for paid, StudioHawk can slot in as a dedicated SEO partner. But if you want a more integrated approach, a full-service ecommerce agency like eComOne may be the better operational fit.
What is a Shopify Agency?
A Shopify agency helps ecommerce brands build, grow and optimise their stores on the Shopify platform. The best ones go well beyond development. They combine strategy, design, technical expertise and marketing to help brands grow revenue over time.
The difference between a freelance Shopify developer and a Shopify agency matters. A freelancer can build a functional store, configure apps and customise a theme. But as your ecommerce operation grows in complexity, the limitations of a single person become apparent. Strategic depth, team breadth, accountability: a freelancer can’t provide those things.
Shopify agencies typically offer some combination of the following:
- Shopify store development and design
- Shopify Plus onboarding and migration
- Conversion rate optimisation
- SEO and technical SEO
- Paid media management
- Email marketing via platforms like Klaviyo
- Technical integrations with ERPs, PIMs and fulfilment systems
- Subscription commerce
- Ongoing growth retainers
For brands on Shopify Plus, working with a recognised Shopify Plus Partner agency provides additional assurance. These agencies have been reviewed by Shopify and have demonstrated technical and commercial competence at the enterprise level.
What Services Do Shopify Agencies Provide?
The range of services from UK Shopify agencies has expanded considerably as the platform has matured. Here’s a clear breakdown.
Shopify web design and development covers everything from theme customisation and section-based design to fully bespoke builds tailored to your product catalogue, customer journey and commercial model.
Shopify Plus migrations are in growing demand as brands move from Magento, WooCommerce and BigCommerce. A quality migration service covers data transfer of products, customers and orders, SEO continuity through redirect management and URL mapping, third-party integration re-establishment and thorough post-launch testing.
Conversion rate optimisation uses analytics, heatmaps, session recordings, user research and A/B testing to improve the percentage of visitors who buy. Small CRO gains compound significantly. A one percentage point improvement in conversion rate can mean substantial additional annual revenue for a store with meaningful traffic.
Shopify SEO and technical SEO addresses the specific challenges Shopify stores face in organic search. Canonical tag handling, faceted navigation management, collection page optimisation, product schema, site speed, Core Web Vitals, internal linking and non-branded keyword strategy. It requires platform-specific knowledge that a generalist SEO agency often doesn’t have.
Klaviyo email marketing covers automated revenue-generating flows: welcome sequences, abandoned basket, post-purchase, browse abandonment, win-back and VIP programmes. Plus regular campaign management and list segmentation.
App integrations connect Shopify to the tools a brand needs to operate: review platforms, loyalty programmes, subscription tools, live chat, returns management and customer service.
ERP and PIM integrations are essential for larger ecommerce operations managing complex inventory, multi-channel fulfilment or a large product catalogue. These integrations are technically demanding and need agency-level expertise to implement reliably.
International ecommerce covers Shopify Markets configuration, multi-currency handling, localised content, tax compliance and international fulfilment setup.
Subscription ecommerce implements recurring revenue models via tools like Recharge or Shopify Subscriptions. These require specific UX design and technical configuration to perform commercially.
Retainers and ongoing support give you sustained access to agency resource across development, SEO, CRO and marketing. For most growing ecommerce brands, this is the highest-value engagement model.
Why Hire a Shopify Agency?
UK ecommerce is more competitive than it’s ever been. Customer acquisition costs have risen consistently across paid channels, with CPCs up year on year for the majority of industries. Organic search is harder to win in competitive categories. Customer expectations around site experience and delivery keep going up. And that’s unlikely to change.
In that context, the operational and strategic capability to stay ahead matters more than it used to. A specialist Shopify agency brings a few things that are hard to replicate in-house or through a generalist supplier.
Specialist ecommerce expertise. The best Shopify agencies have worked across dozens of ecommerce brands. That gives them pattern recognition an in-house team or generalist agency can’t match. They’ve seen what works in your category, they understand the platform properly, and they can apply that knowledge directly to your commercial challenges.
Integrated capability. CRO insights inform SEO strategy. Email data informs paid media targeting. Development decisions get made with marketing performance in mind. When agencies work in silos, these connections get missed. When they work together, you compound the gains.
Speed. A full-service Shopify agency moves faster on development and marketing work than an in-house team building capability from scratch, or a brand coordinating multiple freelancers.
Revenue accountability. The better Shopify agencies report on revenue, conversion rate, average order value, customer lifetime value and return on ad spend. Not impressions. Not click-through rates.
How to Choose the Right Shopify Agency
There are dozens of Shopify agencies in the UK. Choosing the right one takes some rigour. Here’s what to evaluate.
Platform expertise should be demonstrable, not just claimed. Ask for Shopify-specific case studies. Request to speak with existing clients on similar platforms. Look at the quality of the agency’s own ecommerce content. Agencies that genuinely understand Shopify can discuss platform-specific technical challenges fluently.
Shopify Plus accreditation matters if you’re on Shopify Plus or planning to move to it. Partner agencies have been reviewed by Shopify and meet specific competency and service standards. It’s a useful minimum threshold.
SEO capabilities deserve careful scrutiny. Many Shopify development agencies offer SEO as a bolt-on service but lack genuine technical depth. Ask specifically about Shopify canonical tag handling, faceted navigation SEO, collection page strategy and Core Web Vitals. The answers will quickly reveal whether SEO is a real competency or a line on a services page.
CRO methodology should be structured and data driven. Ask about the testing framework the agency uses, the tools they deploy and how they prioritise hypotheses. An agency that can’t describe its CRO process clearly is unlikely to deliver meaningful conversion improvement.
Portfolio depth should be assessed on commercial outcomes, not aesthetics. A store that looks beautiful but doesn’t convert isn’t a success. Ask for revenue growth metrics and conversion rate improvements.
Retainer structure and communication will define the quality of your day-to-day relationship. Understand how work is resourced, who your main contact is, what the reporting cadence looks like and how issues get escalated. Cultural fit and communication quality matter as much as technical capability over a long partnership.
Industry experience in your specific category: fashion, health, homeware, food and drink, B2B ecommerce. Agencies that know your sector will understand the buying behaviour, competitive context and operational requirements specific to it.
How Much Does a Shopify Agency Cost in the UK?
Shopify agency pricing varies considerably depending on scope, the agency’s tier and whether you’re engaging for a one-off project or an ongoing retainer. Here are realistic current market benchmarks.
Small businesses and starter builds typically sit between £3,000 and £15,000 for a Shopify store design and development project. This tier covers theme customisation, basic app configuration and standard product and collection setup.
Mid-market Shopify projects covering bespoke design, custom development, migrations, integrations and more comprehensive SEO and CRO programmes typically range from £15,000 to £60,000. At this level you’re accessing genuine platform expertise rather than template-and-configure work.
Enterprise Shopify Plus projects involving complex migrations, bespoke technical architecture, international ecommerce configuration, ERP integrations and comprehensive growth retainers typically run from £60,000 to £250,000 or more. Shopify Plus itself carries an annual licensing cost starting from approximately £2,000 per month for the standard plan, so factor that into your total cost of ownership.
On the retainer side:
- Shopify SEO retainers typically start from £1,500 to £3,000 per month for a meaningful programme
- CRO retainers are similar
- Full-service growth retainers combining SEO, CRO, email and paid media typically start from £4,000 to £8,000 per month
And if you’re wondering how much Shopify itself costs in the UK: standard plans run from £25 to £65 per month, Shopify Plus starts at approximately £2,000 per month, and app subscriptions can add £200 to £2,000 or more per month depending on the tools you use.
The right question isn’t “what’s the cheapest option?” It’s “what investment do we need to hit our commercial goals?” A well-run SEO or CRO programme that returns three to five times its cost in incremental revenue is a fundamentally different thing from a cheap one that delivers neither results nor accountability.
How Long Does It Take to Build a Shopify Store?
Build timelines vary considerably. Here’s a realistic guide.
Template-based Shopify builds using a premium theme with light customisation: two to four weeks. Right for new businesses launching a straightforward product catalogue with no complex integrations.
Custom Shopify builds involving bespoke design, significant theme development and more complex product configuration: six to twelve weeks. This includes design, development, content population, testing and refinement before launch.
Shopify Plus projects involving custom development, complex integrations, large catalogues or multi-market setup: twelve to twenty weeks from kick-off to launch. Larger and more technically complex projects can take longer.
Platform migrations add complexity beyond a new build. A thorough Magento-to-Shopify Plus migration done properly, including URL mapping, redirect implementation, data validation and post-launch monitoring, typically takes sixteen to twenty-four weeks. Rushing a migration to hit an arbitrary deadline is one of the most common causes of significant organic traffic loss. Don’t do it.
CRO programmes are ongoing. But a structured testing programme takes three to six months to generate statistically significant insights across multiple test cycles.
SEO on a newly launched Shopify store needs to start immediately. But meaningful organic traffic growth in competitive categories typically takes six to twelve months. Technical SEO should be addressed at launch. Content-led organic growth requires sustained investment over time.
What Should You Look For in a Shopify Plus Agency?
Shopify Plus is Shopify’s enterprise tier, built for high-volume merchants. It includes Shopify Functions for advanced checkout customisation, Launchpad for campaign automation, Flow for workflow automation, Shopify Markets for international ecommerce and access to the Wholesale channel.
If you’re evaluating Shopify Plus agencies, look for evidence of these specific capabilities.
Complex migration experience from Magento, WooCommerce, Salesforce Commerce Cloud or similar platforms. Not just “we’ve done migrations” but actual case studies, references and a defined process for managing data integrity and SEO continuity.
Custom Shopify development depth beyond theme customisation: Shopify Functions for custom checkout logic, Shopify Scripts and custom app development where standard solutions aren’t enough.
Headless commerce for brands whose UX, performance or content requirements go beyond what a standard Shopify front end can deliver. Headless adds complexity and cost. But for certain brands it’s the right architectural decision.
Subscription commerce experience that covers checkout UX, subscription management, customer communications and churn reduction. Not just the technical implementation.
Internationalisation via Shopify Markets including multi-currency, multi-language, geo-targeted content, duty and tax handling and market-specific SEO.
Technical SEO at scale: collection page optimisation across large catalogues, faceted navigation handling, international hreflang, schema markup at scale and Core Web Vitals across a complex theme.
A long-term partnership mindset. The most value from a Shopify Plus agency comes over time, not from a one-off project. Look for agencies that are genuinely interested in your commercial performance, not just delivery against a specification.
Ecommerce SEO and Shopify Growth
Organic search remains one of the highest-return acquisition channels available to ecommerce brands. But only when it’s approached with real technical and strategic depth. For Shopify stores specifically, that requires platform-specific expertise a generalist SEO agency often doesn’t have.
Technical SEO for Shopify starts with understanding the platform’s structural quirks. Shopify generates duplicate URLs through its collection-filtered product page structure, which creates canonical tag problems if not handled correctly. Faceted navigation — size, colour and price filters — can generate thousands of thin, duplicate pages that consume crawl budget and dilute domain authority if you don’t manage them with a coherent indexation strategy.
Core Web Vitals are a confirmed ranking signal in Google’s algorithm. Shopify’s app-heavy ecosystem can create performance challenges. An agency that knows how to audit and improve Largest Contentful Paint, Interaction to Next Paint and Cumulative Layout Shift on Shopify specifically is adding measurable commercial value.
Collection page optimisation is one of the most commercially impactful areas of Shopify SEO. And one of the most consistently underdeveloped. Collection pages targeting high-intent category keywords are often the highest-converting landing pages on an ecommerce site. Optimising them for organic visibility and conversion simultaneously requires both SEO and CRO expertise. Most agencies do one or the other.
Product schema markup enables rich results in Google Search: price, availability, review ratings and shipping information. With Google Shopping integrating more deeply into the organic search experience, and with AI-driven results changing how product queries are handled, structured data is increasingly important for visibility beyond the standard organic listings.
Non-branded traffic growth is the clearest indicator of a well-functioning ecommerce SEO programme. Any store gets some branded search traffic. The commercial value is in capturing demand from customers searching for products or categories without a brand in mind. At eComOne, our SEO programmes focus specifically on this: building organic visibility for the category and product keywords that represent new customer acquisition.
Choosing a Shopify agency is one of the most commercially significant decisions you’ll make as an ecommerce brand. The difference between an agency that genuinely understands ecommerce and one that’s competent at web development shows up directly in your revenue performance over time.
The agencies in this list represent some of the strongest Shopify expertise available in the UK in 2026. Each has different strengths. The right choice depends on where you are in your growth journey, what your most pressing commercial challenges are and what kind of long-term partnership you want to build.
Prioritise ecommerce experience over general digital marketing experience. The commercial model of an online store requires specific expertise to understand and improve. Generalists won’t cut it.
Think beyond the launch. The most valuable agency relationships are built over time. A great Shopify Plus build with no ongoing SEO, CRO or retention investment will underperform a good build that’s continuously optimised. Every time.
Invest in SEO and CRO together. Acquiring traffic that doesn’t convert is wasteful. Having a high-converting store that receives no organic traffic is equally limiting. The brands that grow fastest in ecommerce treat these as connected disciplines, not separate budget lines.
If you’re looking for an ecommerce-first agency combining technical Shopify SEO, CRO, Klaviyo and paid media into a commercially coherent growth programme, speak to the eComOne team.
