Top Shopify Agencies in the UK for 2026

Shopify in the UK isn't a small-business thing anymore; it's where a big chunk of British retail lives now.

Stats by Store Leads suggest that there are over 250,000 Shopify stores active in the UK as of mid-2026.

While it’s good news for Shopify, the same can’t be said for you! Especially if your store looks like the other 249,999.

This is a major reason why the agency you pick matters more than people think. Anyone can launch a store in a weekend, but:

• Getting it fast
• Indexable on Google
• Ensuring it converts visitors into buying customers
• Managing running stock, ads, and customer service

These are the parts where most brands give up and need a hand.

Therefore, this blog takes a closer look at the top Shopify agencies in the UK for 2026. Let’s get started.

Here's a quick snapshot of the 10 top agencies in the UK.

1. UncannyCS

First on our list of the top Shopify agencies in the UK is UncannyCS, a complete Shopify experience partner. They are your go-to partners from the first build to running the store smoothly after launch.

They understand Shopify like no other, delivering a store that isn't just built to look good, but to show up on Google and in AI search. With 160+ projects delivered and a team of 50+ experts, they've already seen most of the problems Shopify brands run into.

• Store builds, migrations, and custom themes are all covered, along with maintenance and support once you're live.
• Tired of juggling a developer, an SEO agency, and a support freelancer? This is the one-stop option.
• Ask about their maintenance plans early, because that's where a long-term partner really earns its keep.

2. We Make Websites

Selling in five countries with five currencies? We Make Websites has done a lot of that. Being one of the early Shopify Plus adopters, the London team now mostly does enterprise and headless builds for brands like Good American and Vollebak.

• Services include enterprise builds, headless setups, and international store rollouts.
• It's a good fit for established brands selling across several countries and currencies.
• Smaller stores on a tight budget may find it more agency than they need.

3. Eastside Co

Eastside Co's pitch is simple: one agency for design, development, and marketing. Around on Shopify since 2012, they've grown well past their London office, and for a brand that's tired of chasing three suppliers for one launch, that alone is a selling point.

• Services include Shopify Plus builds, custom app work, design, migrations, and growth support.
• It's a good fit for brands that want the same team handling launch and marketing.
• Having everything under one roof also means fewer handovers and fewer things lost along the way.

4. Swanky

Exeter-based, running since 2010. Swanky's sweet spot is subscriptions and multi-market setups, two things that sound easy in a sales call and then turn out to be where a standard theme falls over.

• Services include Shopify Plus builds, migrations, design and development, plus email and retention support.
• It's a good fit for subscription brands and stores expanding into new countries.
• The retention side is a bonus if repeat orders drive most of your revenue.

5. Space 48

Space 48 is from Manchester and is quite technical. Large catalogs, complex back-end systems, lots of moving parts. If you're launching with 40 products, they're probably not your crowd yet.

• Services include Shopify builds, UX, CRO, and ongoing development support.
• It's a good fit for established retailers replatforming a large, complex store.
• Budgets here tend to sit on the higher side, so it isn't a starter-store option.

6. Quickfire Digital

ERP, warehouse system, custom app, plus three more tools that all need to talk to Shopify? That kind of mess is exactly what Quickfire Digital in Norwich likes to sort out.

• The agency builds complex Shopify stores, including ERP and other custom apps.
• It’s a great option for brands looking to connect their entire ecosystem to a single architecture.
• The team also watches conversions, so the build isn't purely a technical exercise.

7. Underwaterpistol

Underwaterpistol has been around since 2006, making them one of the older names on this list. And it shows in how they work. You won't find them reskinning a template and calling it a day; they design almost everything from scratch. Ooni, the pizza oven brand, is probably the client most people would recognize.

• If your product sells on looks (think furniture, fashion, or homeware) this is where they're at their best.
• Custom design takes time, so don't go to them with a three-week deadline.
• Ask to see a couple of live stores and not just mockups, because that's where their work really shows.

8. Fourmeta

A brand moves to Shopify, the new site looks great, and three weeks later half the Google traffic is just gone. Nine times out of ten, nobody mapped the old URLs properly. This is where Fourmeta steps in to plan redirects and URLs before the switch, not after the damage.

• Moving off WooCommerce or Magento? This is the one we'd talk to first.
• On the first call, ask how they handle redirects. Their answer will tell you a lot.
• They're less about flashy design and more about keeping what you've already built up on Google.

9. Statement

Statement, also in London, mixes Shopify builds with SEO and paid media. Works well if you want the team that built the store to also be the team that grows it.

• Services cover Shopify design and development alongside SEO and paid media.
• It's a good fit for brands that want growth planned in from day one.
• It also saves you briefing a separate marketing agency once the store is live.

10. Noughts and Ones

Noughts and Ones in Bristol mostly works with sustainable, purpose-driven brands. Plus, they're strong with Klaviyo, which is handy if email is where a good share of your sales come from.

• Services include Shopify builds with a strong focus on Klaviyo email and retention.
• It's a good fit for ethical and eco-conscious brands that want a partner who shares those values.
• Email-heavy stores will get the most out of what this team does best.

Put simply, it's a team that only builds and grows Shopify stores.

Most have designers, developers, and a few marketing people under one roof. You could hire each of those separately, of course, and plenty of brands try that first.

The trouble starts when the designer hands over something the developer can't build, and you're stuck in the middle sorting it out.

There's another difference worth knowing.

A general web design studio may create a Shopify store once or twice a year. A Shopify agency creates one weekly; as a result, they know which apps don’t work together, which elements can't be customized during checkout, and the platform’s limitations.

Building the store is usually just the start. Here's what else you'll find on most agencies' service pages.

a. Shopify Store Development

This is the part everyone pictures. You add products, set up payments and shipping, and test the checkout so nothing breaks on the first real order.

b. Shopify Plus Development

Shopify Plus is the plan bigger brands move to once they're doing serious volume. It opens up things the standard plan won't, like custom checkout rules, a separate wholesale store, and automations through Shopify Flow. An agency that knows Plus well can save you a lot of trial and error here.

c. Store Migration

Coming over from WooCommerce or Magento? Then products, customer accounts, and old orders all need moving across. The bit people forget is redirects, and skipping those is how stores lose their Google rankings almost overnight.

d. Custom Theme Development

A ready-made theme is perfectly fine when you're starting out. Over time, though, many brands outgrow it. A custom theme gets built around how your own customers browse and buy, and that's usually when conversion rates start to move.

e. Support and Maintenance

No store is ever really finished. Apps push updates, something breaks after a Shopify change, or the marketing team wants a new landing page by Friday. That's why most agencies offer a monthly support plan after you go live.

Can you build a Shopify store on your own? Yes, and many brands do at first.

The problems typically arise afterward. You add one plug-in, then another, and it gets slower with each installation. A plugin update takes down the entire shopping cart mid-sale. Maybe you switch platforms and suddenly lose almost half your organic search visitors within days.

Think of it much like fixing up a home. Doing the painting is something you can probably handle yourself, but wiring the kitchen – that’s something you would definitely get help with.

That's because the company has already fixed these issues for other stores, saving you the trouble. Meanwhile, your team can focus entirely on products and customers instead of themes.

Even with the best Shopify agencies, fit matters more than fame. A few checks before you sign go a long way.

Check Shopify Experience

First, are they an official Shopify partner? And if you need Plus, have they shipped Plus projects? Top Shopify experts will happily walk you through stores similar to yours.

Review Previous Projects

Case study pages are polished on purpose. Open the live stores on your phone instead, check the speed, go through checkout, and if you can, talk to a past client.

Compare Services and Pricing

Get two or three detailed quotes and look at what's included, not only the total. The cheapest quote often becomes the costliest build once fixes start.

Check Ongoing Support

What happens after launch? If the payment app breaks on a Friday night, who's picking up the phone, and how fast?

Depends a lot on how custom your store is. Here's a rough idea of UK agency pricing.

Top Shopify development companies usually charge at the top end of this. Worth it? If the store brings in most of your revenue, then yes.

A freelancer is a great fit for small businesses, urgent projects, and low budgets. The disadvantage is that it is only one person. They cannot be both a designer, developer, SEO specialist, and help desk at the same time, and if something happens to them or they find a more important client, your project will have to wait.

The agency is more expensive, but you get a team that backs each other up and a fixed support package after launch.

A hybrid approach is popular among many brands - agencies build the website, while freelancers make small changes later. However, for a big store, choosing the best Shopify development company adds to their business.

All the best Shopify agencies listed here build good stores. What differs is where they're strongest, be it migrations, Plus, design, or growth.

So start from your own needs, and think about where the store should be in two years, not just on launch day. Then shortlist two or three of the top Shopify agencies above, look at their actual work, and only then get into numbers.
