Picking among the top Shopify Plus development agencies in 2026 should be straightforward. It rarely is. Search for one, and you will find hundreds of certified partners, similar service pages, and near-identical promises about “driving growth.” The harder question is: which of those Shopify Plus agencies in the UK, one actually fits your project, your industry, and the stage your business is at right now?
This top Shopify Plus development companies list brings together ten of the best Shopify Plus development agencies in the UK - all official Shopify partners, covering different specialisms, client profiles, and working styles. We don't pick the winners, the goal is to give you enough detail to make that call yourself.

Why hire a Shopify Plus agency in the UK?
Not every Shopify project needs a specialist agency, however, some very much do. Standard Shopify is built to be self-serve. Shopify Plus is a different animal: the shift from Shopify Scripts to Shopify Functions, which fully replaces Shopify Scripts from June 2026, is one example. Then you have Checkout Extensibility, multi-storefront architecture, B2B native features, and advanced automation via Shopify Flow, all of which require hands-on platform knowledge that takes time to build.
Top Shopify Plus development companies in the UK bring that knowledge day one. They already know where projects tend to get more expensive, which integrations can cause trouble, and which tools are worth the spend. It usually speeds things up and cuts down on unnecessary complications. If you are dealing with Shopify ERP integration, Shopify headless, or multiple markets, a certified Plus partner is often the better option.
How did we put together the top Shopify Plus development companies?
Every agency on our list of the best Shopify Plus development agencies is a verified official Shopify partner, listed in the Shopify Partners Directory. Beyond that, we looked at:
specialisation (what each agency does best and for whom)
publicly verifiable client work
independent reviews across Clutch and similar platforms
We didn’t rank these agencies based on size or revenue. The best partner depends on what a business actually needs, and that is not always the biggest team. To make the list easier to review, we kept the structure consistent across every company.

We start our Shopify Plus development agencies list with DigitalSuits, which is a certified Shopify Plus Partner and full-service Shopify Plus development agency. The team works on custom Shopify builds, headless storefronts, ERP, and Shopify CRM integrations. It also supports brands with ongoing development after launch. Also, Shopify speed optimisation, and platform migrations. Beyond builds, they offer Shopify CRO, performance audits, and dedicated developer teams.
They have partnered with companies such as:

Location: London (offices in Birmingham, New York, Hamburg)
Focus: Enterprise ecommerce, custom development, Shopify marketing
Eastside Co offers a wider ecommerce service mix for brands that need both technical work and ongoing commercial support. Their customer list includes well-known consumer companies such as Volkswagen, Unilever, Chelsea Football Club, Carex. Portfolio diversity is important when you need an agency that has already worked in high-traffic scenarios with complex and unique requirements. The team's focus is on UX & design, Shopify development, ecommerce strategy, Shopify apps, and marketing. Their work regularly involves multi-currency support, international tax management, and custom Checkout Extensibility implementations.
Strengths:

In-house tools that help speed up development across recurring tasks
Hands-on experience with international Shopify stores, including Markets, currencies, and local storefront setup
Ideal for DTC brands in growth mode and larger retail teams that need a technical partner, especially for Shopify Plus, headless builds, and multi-market expansion.
Radiant
Location: Birmingham
Focus: Shopify Plus development, re-platforming, and design
Radiant, or Full Fat Commerce (as previously known), has worked on Shopify stores since 2018. The agency is best known for Shopify Plus projects, with a strong focus on custom design, replatforming, and redesign work. They bring a global talent model to UK brand work. The company can assemble specialist teams for projects without the constraints of a single-office headcount. The agency's work is particularly strong in tech integrations, data migration, and store performance audits. They work with brands coming off legacy platforms with messy data and complex product structures. Radiant's methodical approach to re-platforming, including SEO preservation and redirect management, reduces the risk that typically comes with a move.
Strengths:
Proven in complex re-platforming scenarios with a focus on data integrity and SEO continuity
A strong design focus, balanced with the performance a Shopify Plus store needs
Solid technical capability across integrations and custom app work
Ideal for brands that move from Magento or custom platforms and need a team that can manage the technical work and deliver a strong store.
Atwix
Location: Global (serving UK market)
Focus: B2B enterprise Shopify Plus, ERP integrations, complex wholesale operations
If your project has manufacturer or distributor requirements, Atwix is one of the few agencies with real experience in that space. The team has more than 15 years of B2B ecommerce experience and includes 300+ certified developers. The platform developed its own integration platform, Sirius, for more complex Shopify Plus setups. That covers custom pricing, bulk ordering, multi-level account structures, and ERP connections with NetSuite, SAP, Oracle, and Infor. Atwix has delivered more than 180 enterprise B2B projects. For a straightforward B2C store, this may be more than you need. But for B2B or hybrid commerce, Atwix stands out for the kind of work it knows best.
Strengths:
Specialized knowledge in B2B Shopify Plus solutions with native wholesale features.
Proprietary middleware (Sirius) cuts enterprise integration time significantly
Long-term partnership model
Ideal for manufacturers, distributors, and wholesalers
Wiro
Location: UK
Focus: DTC home and lifestyle brands, CRO, Shopify Plus development
Wiro has built a distinct niche around direct-to-consumer brands in the home, interior, and lifestyle sectors. They stick to a certain kind of client. Usually, that means purpose-driven brands that want to fix conversion issues and grow further. Their working model runs in three layers: Audit → Build → Growth Retainer. That structure means the engagement does not stop at launch. A/B testing, CRO, Shopify 2.0 work, and UX fixes based on real store data are part of their core services. That is useful for brands with solid traffic but poor conversion.
Strengths:
Narrowed specialisation in home and lifestyle DTC
Structured growth retainer model for ongoing optimisation
Strong CRO capability, including A/B testing, behavioural analysis, and headless integrations
Ideal for DTC home, interior, and lifestyle brands looking for performance-focused Shopify Plus builds with ongoing CRO support.
Charle
Location: London
Focus: Shopify Plus development, SEO, design, UX, and CRO
Founded in 2018, Charle has grown quickly into the agency for brands that want both creative quality and measurable organic performance. Their positioning as a "search-first" agency is more than a tagline. They consider SEO structure, GEO for AI search, and user behaviour from the start of the build. These are part of the main setup, not something they add later. Notable clients include Cambridge Satchel, Billionaire Boys Club, 111SKIN, and Muc-Off.
Strengths:
Genuine SEO-first build methodology, including AI search visibility tracking
Strong across full-store builds, migrations, and ongoing retainers
Ideal for DTC and retail brands that prioritise design quality, organic search performance, and want a long-term creative and technical partner in London.
Cake Agency
Location: UK
Focus: Retail strategy, Shopify Plus development, data-driven growth
Cake Agency occupies a useful position in this list. They describe themselves as an agency "founded by retailers for retailers". Where some agencies lead with technology, Cake leads with a commercial understanding of how retail businesses actually operate. Their Shopify Plus work reflects customer habits, margin pressure, and long-term value, from an early stage. They work mostly with fashion, beauty, and lifestyle brands. Alongside Shopify Plus development, they also bring a strong commercial view. That makes a difference for brands that want a partner who understands retail, not just the build.
Strengths:
Retail-native perspective built into strategy and development
Cooperative, a partnership-focused approach to work ideal for internal teams.
Experience across fashion, beauty, and lifestyle sectors
Ideal for retailers that need a Shopify Plus agency that understands commercial operations, not just development.
blubolt
Location: Bath, UK
Focus: Mid-market and enterprise Shopify Plus, custom apps, and design
blubolt has been in ecommerce since 2006, longer than most of the agencies on this list. They built their own ecommerce platform (bluCommerce) before pivoting fully to Shopify Plus. The agency brings genuine platform-agnostic engineering thinking to every project. That history shows in their approach: they are known for revenue-driving custom apps. This agency makes sense for brands that need something more tailored than what the Shopify App Store usually offers. They build custom Shopify apps alongside the store itself.
Strengths:
Nearly two decades in ecommerce with deep Shopify Plus expertise
Custom app development capability alongside standard store builds
Strong in migrations and advanced integrations for mid-market retailers
Ideal for established mid-market and enterprise brands in fashion, beauty, and lifestyle that need bespoke Shopify Plus solutions and custom app development.
Quickfire Digital
Location: Norwich, UK
Focus: Shopify Plus development, D2C growth, conversion optimisation
Quickfire Digital won European Ecommerce Agency of the Year in 2022. Their work covers many kinds of ecommerce projects, from heritage brand relaunches to fast-growing D2C subscription businesses. Their working philosophy is centred on growth outcomes rather than project delivery for its own sake. Quickfire's strength is to combine technical Shopify Plus capabilities with a growth strategy.
Strengths:
Award-winning track record with recognisable UK and global consumer brands
Growth-first approach, every build is evaluated against commercial KPIs
Experienced with D2C subscription models and complex brand relaunches
Ideal for ambitious D2C brands with strong growth trajectories seeking a commercially minded Shopify Plus partner.
Underwaterpistol
Location: London
Focus: Challenger brands, development, custom integrations, UX
Underwaterpistol was founded in 2001, which makes it the longest-running ecommerce company in this list. That history has produced a distinctive positioning: they work with "rule-breakers". Brands with big ambitions and a desire to build standout experiences rather than category-average stores. They won Best Shopify Plus Agency EMEA at the Yotpo Partner Awards, which reflects that creative-technical balance. Their client work illustrates their strength in complex, design-heavy projects that also require serious backend work.
Strengths:
Over two decades of specialist Shopify Plus experience
Strong in complex custom integrations, including marketplace and multi-vendor builds
Proven track record across high-profile brand relaunches and performance-critical projects
Ideal for challenger brands and established retailers that need a technically advanced Shopify Plus build with a strong creative edge.
The bottom line on top Shopify Plus development agencies
This list of the top Shopify Plus development agencies in the UK can help you understand the market. However, it will not tell you which team is right for your business. That part depends on your setup, your goals, and the kind of work the project actually requires. A brand with a complex migration, for example, will not look for the same partner as a retailer that needs CRO support or a custom app.
Our best Shopify Plus development agencies list becomes more useful when you read it with context, not just as a ranking. The real value is in how well an agency's experience matches your own priorities. The same applies to the best Shopify Plus development companies. The strongest choice is usually the one that understands the work in front of it, has solid proof behind it, and feels like a good fit for the way your team.
Frequently asked questions
What is the difference between a Shopify Partner and a Shopify Plus Partner?
Any agency can apply to become a Shopify Partner. Shopify Plus Partner status is a separate, higher-tier accreditation. It requires demonstrable experience delivering Shopify Plus projects, the enterprise version of the platform.
Also, it has a minimum revenue threshold and client satisfaction criteria. If your project uses Plus-specific features (Checkout optimisation, Shopify Functions, multi-storefronts, Shopify Flow at scale), working with a Plus-certified agency reduces the risk of hitting knowledge gaps.
How much does a Shopify Plus agency project typically cost?
Shopify agency pricing in the UK can sit anywhere from a small setup budget to a much larger build, mainly because no two projects are priced the same.
As a rough guide:
£1,000-£5,000 for a basic Shopify setup
£5,000-£20,000 for custom store design, migrations, or integration work
£20,000-£50,000+ for larger builds or Shopify Plus projects
£90-£150 per hour is a common hourly range for UK agencies
The price depends on the amount of work involved.
How long does it normally take to establish a Shopify Plus store?
A standard custom theme build with integrations usually takes 8 to 16 weeks from start to launch. Complex projects (ERP integrations, headless builds, or major data migrations) can run 16 to 24 weeks or more. Timeline depends on how ready your content, product data, and internal sign-off processes are. Delays on the client side are one of the most common reasons projects run long.
