Powerlete and Fittr Nutrition are ours. We build them, buy the media, and live with every conversion rate before it reaches a client build. When we test a checkout change or a paid-social angle it happens on our money first, which is why the playbook we bring you is not theory.

Shopify Agency London
We partner with brands to design, build, launch and grow Shopify stores.
We are a Shopify website agency, and an ecommerce agency London brands come to when the storefront is the business rather than a channel. All of it sits under one roof: developers, designers, search, paid media, email and conversion work, for brands across the US and the UK. Most agencies sell one of those and subcontract the rest.
A London ecommerce agency is not the same thing as a web studio that takes the occasional Shopify project, and the difference shows up in what gets measured. We are ecommerce specialists: the brief is revenue rather than pages, and everyone who touches a project has shipped and run stores before. That is what an ecommerce specialist agency ought to mean, and frequently does not.
As a Shopify web agency, London is home but the work is not, and we run our own stores on the same stack, so the recommendations have been paid for with our own money before they reach a client. That means a store gets designed, built, launched and then actually grown, rather than handed over on launch day and left to drift. Cream Cornwall came for a build and a migration and stayed for the consultancy. Powerlete and Fittr are ours outright, and they are where anything new gets tested first.
Search shopify developer london or shopify developers london and most results are a design studio that also writes code as a sideline. We are built the other way round: platform work comes first, theme and app development, integrations and migrations, and design is built around that rather than layered on top afterwards. The same holds if what you are comparing is a shopify development agency uk-wide rather than just in the capital: every shopify website london we build is maintained afterwards by the same senior developers who wrote it, not handed off once it launches.
Shopify Monthly Support Agency
A developer who already knows your store, on call every month, not a ticket queue starting from zero.
We run ongoing Shopify support and maintenance retainers alongside dedicated speed optimisation, for stores that need someone who already knows the codebase rather than a help desk reading the ticket before it reads the store. Monthly work that stays fixed, theme and app updates that do not break checkout, and a senior developer on call when something actually breaks.
Fittr is one of our own stores and it gets exactly what a client store gets, which is the honest way to test whether a support retainer is worth paying for. Knack Snacks runs support and speed work through us alongside their paid ads and email, on a subscription-first store where a slow product page costs a subscriber rather than just a sale. Site speed sits with the same people as the support ticket, so a Core Web Vitals fix and a broken discount code get handled by someone who already has the context.
Shopify SEO & GEO Agency
Search does not end at Google any more, and neither does our SEO work.
As a Shopify SEO agency we run technical audits, content and keyword targeting, and the site architecture work that actually moves rankings rather than a report that says it will. Ecommerce SEO across Shopify and Shopify Plus, and alongside it generative engine optimisation for the growing share of buyers who now ask ChatGPT or an AI Overview before they ever open a search results page.
Black Sand started with no storefront at all and now sells worldwide, with search as one of the channels that got it there. Waldo runs its organic search alongside its paid ads with us too, on a Swiss watch brand competing where legacy names own the results. Search visibility in either case is not a vanity metric, it is the channel that pays for itself once it works, so the same people who build the store build the content and the internal linking that get it found.
Shopify Developers UK
We develop Shopify stores, and the apps and themes that extend them.
In-house Shopify developers. London is where the team sits, writing Liquid, JavaScript and the theme architecture underneath it rather than assembling a page builder. Custom themes built from scratch where the brand needs one, existing themes extended properly where it does not, and the judgement to say which of those a store actually needs.
Beyond the storefront: private Shopify apps for the workflows no public app covers, headless builds where the front end genuinely warrants one, and the integrations that connect a store to the systems already running the business. This is the Shopify development London agencies most often subcontract, and it is the part we keep in-house. Every build gets the same performance and technical SEO discipline, because a fast store nobody can find is only half the job.
Shopify Web Designer UK & Shopify Web Design Agency
We design Shopify stores to engage and convert, not just to win awards.
Shopify web design that starts with the buying journey rather than the moodboard: competitor and data discovery first, wireframes that decide where the page earns its money, then high-fidelity design on top of a structure that already works. Your branding, your photography and your tone of voice, arranged around reduced clicks to checkout and product discovery that finds people the thing they came for.
Design and build sit with the same team here, which is the part that usually goes wrong elsewhere. The Shopify designer London brands actually meet is the one drawing the page, not an account manager relaying it, and a design signed off in isolation then thrown over the wall to developers loses the detail that made it good. Ours is drawn by people who know what the theme will do with it, and reviewed against real product data instead of placeholder images.
Shopify Agencies London
Why migrate to Shopify, and what it actually costs to get it wrong.
We have moved brands to Shopify and Shopify Plus from Magento, WooCommerce, BigCommerce, Salesforce, Wix and Squarespace. The commercial case is usually the same one: a lower total cost of ownership, hosting and PCI compliance that stop being your problem, and an app ecosystem that means the next feature is a decision rather than a development project.
The risk is never the platform, it is the move. Most migration horror stories are a redirect map written at the end, product URLs that changed silently, and six months of rankings gone before anybody notices. We treat search continuity as part of the build, which is why the migration page and the SEO team are the same conversation here rather than two quotes from two suppliers.
Shopify Agency UK
Looking for a Shopify Plus agency to grow with, not just launch with?
We are a Shopify Plus partner agency running our own stores on the platform, which is a different claim from having certificates on a wall. Checkout extensibility, Shopify Functions, Markets and B2B are things we have shipped on our own money before quoting a client for them, and the audits we sell start from the same place.
Most of our work is a retained partnership rather than a project with an end date, because the compounding part of ecommerce is what happens after launch. One team across build, search, paid, email and CRO, a roadmap that gets revisited when the numbers say so, and a senior person who knows the store rather than an account manager relaying questions to someone who does.
Shopify Email Marketing Agency
Keep customers coming back with email, SMS and retention marketing.
Ecommerce email marketing that treats the list as an asset rather than a broadcast channel. Welcome, browse and cart flows that run on their own, segmentation so a first-time buyer and a repeat customer never get the same message, and campaigns built around what someone actually bought instead of what the calendar says. SMS alongside it where the message earns an interruption, not on everything.
We build these in Klaviyo, and Powerlete is the store where we find out what works before a client pays for it. Retention is the cheapest revenue in ecommerce and the easiest to leave sitting there, because a flow nobody has looked at in a year still technically sends.
International Shopify Strategy
Shopify international expansion, without running a second business to do it.
Selling into a new market on Shopify is a set of decisions before it is a build: one store with Markets or several, how pricing and currency behave per region, what gets translated and what does not, and which parts of the catalogue should even appear. Get those right and the platform does most of the work. Get them wrong and you have two stores to maintain and one of them quietly rots.
We have taken brands into Europe, the US and further out on Shopify and Shopify Plus, with geolocation, per-territory content and local payment methods that make a store feel native rather than translated. Black Sand went from no storefront at all to selling worldwide, which is the version of this that starts from nothing rather than bolting a second market onto an existing site.
WUKA
Client · build, conversion testing and ongoing support
Shopify Partner Agency UK
Data-driven strategies for Shopify and Shopify Plus.
A Shopify Plus partner agency that argues from the analytics rather than from taste. Competitor and category review, session recordings and heat maps, and the purchase data already sitting in the store, turned into a testing roadmap ordered by what would move revenue most rather than what is quickest to build. Conversion rate optimisation as a programme with a hypothesis behind each test, not a list of best practices applied blind.
WUKA came to us for exactly this: a full store build, then a dedicated run of conversion testing on a product that has to be explained before anyone will buy it. We run the same discipline on our own stores first, which is what the Testbed mark is for and why we can say what actually worked rather than what should have.
Powerlete and Fittr Nutrition are ours. Real stores, on real ad spend, with real customers, and every tactic we sell has been run on our own money first. No account managers relaying briefs between you and the people doing the work: the same team that builds the store runs the search, the ads and the retention after launch.
Our storyPartners
A stack we have already tested, not a list of logos.
The Shopify app store lists thousands of apps, and choosing between them is most of the work. We are a Shopify Plus Partner and we integrate the tools that sit around the platform: Klaviyo for email and SMS, Gorgias for helpdesk, Loop for subscriptions and returns, Junip for reviews, Upstack Data for tracking and attribution, DataFeedWatch for product feeds. Every one of them runs on our own two stores before it reaches a client, which is why the recommendation you get is based on having paid for the thing rather than on who pays a referral. When we tell you something is not worth it, that is us having bought it and found out. And when a brand already runs a stack that works, we integrate with it rather than rebuilding it to suit us.
How we use them
Shopify agency London, questions answered
- Are you a London-based Shopify agency?
- Yes. We are a Shopify Plus Partner headquartered in London, and our team works from here on every project, whether the brand is based in London, elsewhere in the UK, or in the US.
- Do you only work with London brands?
- No. London is our home, not a limit. We build for brands across the UK and the US. Cream Cornwall, one of our clients, trades from three shops outside London, in Falmouth, St Ives and Bath.
- What Shopify services do you offer in London?
- Our Shopify development services in London cover everything under one roof: web design, development, app development, migration, CRO, paid ads, lead generation, ongoing growth partnerships, audits and Shopify POS. Whether you need a new ecommerce website or want to fix the one you have, it is the same team either way. See the full list above.
- Why choose a London Shopify agency over a freelancer?
- A freelance Shopify designer in London covers one discipline well. We cover design, development, migration, CRO, ads and lead generation as one team of certified Shopify experts, so the store and the marketing pointed at it are never designed in separate conversations. If you only need one small thing done, a freelancer may genuinely be the better call.
- Is Elms Agency a fit for a small London ecommerce brand, not just a big one?
- Yes. We work with brands at every stage, from a first Shopify build to an established store outgrowing its current setup, including brands moving across from other ecommerce platforms. The audit and consultancy services exist specifically for brands that want senior input without a full retainer.
- Do you work on Shopify Plus as well as standard Shopify?
- Yes. We are a Shopify Plus Partner, and the larger builds we run are usually on Plus, where the checkout, B2B pricing and multi-store behaviour stop being fixed and start being things you can change. If you are on standard Shopify and wondering whether the step up is worth it, we will tell you when it is not rather than sell you the upgrade.
