Hiring a Shopify Agency in London: What to Look For

London has more agencies calling themselves Shopify experts than most store owners know what to do with. Clutch, Google, and LinkedIn are full of them. Some are excellent. A fair few are not. The challenge is that they all look similar from the outside: the same case studies, the same promises, the same pitch deck. Picking the wrong Shopify agency in London does not just cost money. It costs time, typically 6-12 months before you accept it is not working and start again. This guide is for store owners who want to avoid that.

Why the London Shopify Agency Market Is So Crowded

Shopify holds around 23% of the UK ecommerce software market, making it one of the dominant platforms for British retailers. England alone has over 184,000 active Shopify stores, and London is where a large portion of the agencies serving that market are concentrated.

That concentration is not a problem in itself. Competition is good. But it has produced a lot of agencies that are not really agencies: two developers trading as a studio, often passing work to cheaper contractors overseas. Knowing how to tell the difference before you sign anything is what matters.

Ask Exactly Who Will Work on Your Project

The most useful question you can ask any Shopify agency in London is not how long they have been in business. It is: who specifically will be building my store, and can I speak with them before we start?

Larger agencies often sell you their most senior people in the pitch, then hand your project to a junior team once the contract is signed. This happens often enough that it has a name: bait and switch. The result is work that takes longer, costs more to fix, and requires more of your time to manage.

A senior-led team with real continuity from brief to launch looks different. You get people who have solved the same problems before, who anticipate issues rather than react to them, and who do not need weeks to get up to speed on your stack. Uncover Commerce works this way by design: no juniors, no outsourcing, every project handled in-house by an experienced team based in Glasgow, working with clients across the UK including London.

Outsourcing Is More Common Than Shopify Agencies Admit

Some London agencies have no UK development capability at all. They are project managers with a Shopify badge, subcontracting work to developers in other time zones. The economics work for them. They do not always work for you.

When you are building a store that needs to work across UK payment systems, comply with UK consumer law, and convert British shoppers, direct access to the people making decisions matters. Delays in feedback loops cost money. Miscommunications along a long chain cost more. Ask directly: do you employ your developers? Where are they based? What does a typical working day look like when I need to speak with someone?

What to Actually Check in a Portfolio

Real portfolio work is your best signal. Ask for three or four live stores you can visit yourself, not screenshots or video walkthroughs. Click through the checkout. Test it on mobile. Check load speed. If you want a technical benchmark, Core Web Vitals and Shopify site speed are worth understanding before you evaluate agency work.

Then ask about results, not just design. Did conversion rate improve after the build? By how much? What was the biggest problem they solved and how did they approach it? Agencies that can talk about outcomes in specific terms are agencies that think about outcomes, not just deliverables. That distinction compounds over time.

Does Your Shopify Agency Need to Be Based in London?

No. The case for a local agency is largely habit rather than logic. A decade ago, in-person meetings mattered more. Now, the best Shopify work in the UK is done by teams that communicate clearly, manage projects with discipline, and have the technical depth to solve problems fast. None of that requires a London postcode.

Uncover Commerce is based in Glasgow and works with brands across the UK and internationally. Our clients in London and the South East get the same thing any other client does: direct access to the people doing the work, clear timelines, and no layers between them and us. See how we work with London-based brands if you want specifics on what that looks like in practice.

What matters is track record, team seniority, and process. Not where the office is. Over 12 years and 100+ projects, the clients who have had the best outcomes were the ones who cared about those three things and almost nothing else.

The Problem Might Not Be What You Think

Most established Shopify brands approach agencies with what they believe is a traffic problem. They want to rank higher, grow their paid channels, get more visitors. Sometimes that is the right focus.

But across more than 100 Shopify projects over 12 years, the issue we see most often is conversion. A store getting 30,000 sessions a month and converting at 1.2% has a ceiling that more traffic will not lift. Fix the conversion rate to 2.4% and you double revenue without spending an extra pound on acquisition. Most Shopify brands do not have a traffic problem. They have a conversion problem.

Before committing to any agency on development work or an ongoing retainer, do an honest audit of where your growth is actually blocked. Our conversion growth retainer is built around exactly this: finding and fixing the friction in your existing traffic before adding more of it.

The right Shopify agency, whether they are based in London or Glasgow, is the one that can show you real results, name the people who will do your work, and give you a straight answer about how they operate. Start with those questions and you will filter out most of the noise quickly. If you want a second opinion on where your store stands, get in touch and we can take a look.
