Headless 
E-Commerce Agency
ECS® is a headless Shopify agency in London building decoupled storefronts for Shopify Plus brands. We specialise in Hydrogen, Next.js, and Storefront API architecture — so your frontend can move as fast as your product roadmap.
If you need a London headless commerce agency that ships production-ready experiences (not demos), you're in the right place.
HEADLESS SHOPIFY
London headless commerce agency
Going headless is a strategic decision, not a trend. Brands come to us when Liquid themes hit a ceiling — custom UX, multi-channel experiences, subscription complexity, or performance targets that a traditional Online Store theme can't meet.
As a headless Shopify agency, we design the commerce architecture first: Shopify Plus as the system of record, Storefront API / Hydrogen (or Next.js) on the frontend, and the integrations your ops team actually needs. We've delivered headless builds and ongoing headless support for ambitious UK brands including Dishpatch.
Need a full rebuild, a phased migration, or a specialist to support an existing headless stack? Talk to our headless team — or browse client reviews.
The ECS® Headless Advantage
We combine Shopify Plus depth with modern frontend engineering. Whether you need a greenfield headless storefront or to evolve an existing one, we deliver through:
01
Architecture that scales
Shopify Plus + Storefront API / GraphQL foundations built for catalogues, markets, and complex product logic — without boxing you into a theme.02
Frontend freedom
Hydrogen, Next.js, or React storefronts with the performance, SEO controls, and UX flexibility your brand team expects.03
Commerce integrations
Subscriptions, search (e.g. Algolia), CMS, ERP, and custom APIs wired cleanly so headless doesn't become a maintenance trap.04
Ongoing headless support
Post-launch optimisation, feature delivery, and technical ownership from the same team that builds — see our Shopify support offering.
WHEN TO GO HEADLESS
Headless commerce development in London
Headless isn't right for every brand. We recommend it when you need custom storefront UX, multi-experience journeys, tighter performance budgets, or integrations that fight a monolithic theme. For many merchants, a well-built Shopify theme or Plus Online Store is still the smarter path — and we'll tell you that honestly.
When headless is the right call, our London-based team owns discovery, architecture, build, launch, and ongoing iteration. Pair this with our Shopify development capability when you need theme work, apps, or hybrid approaches alongside a headless frontend.
