Ecommerce Website Cost in the UK: What a Store Really Costs to Build
A UK ecommerce build can be a few hundred pounds on a template or well into five figures for a bespoke store, because price tracks what the shop has to do, not a fixed rate card. Here is what drives the number, and what a senior-led build costs stated openly.
In the UK, ecommerce websites typically run from a few hundred pounds for a self-built Shopify template to £15,000 or more for a bespoke store, with most serious small and mid-sized builds landing between £5,000 and £20,000. A managed Shopify build sits in the lower half of that; heavily customised or headless stores sit above it. Rogue Logic builds bespoke ecommerce sites from £5,000, priced against what your store actually needs to do rather than a hidden rate card.
Ecommerce website cost, in full.
"How much does an ecommerce website cost?" is a fair question with an unhelpfully wide answer, because an online store is not one thing. It can mean a self-built Shopify template you set up over a weekend for the price of the monthly subscription, or a bespoke, integrated store with custom logic that runs into five figures and takes months. Both are ecommerce websites. What separates them is not quality of intention but scope: what the shop has to sell, to how many people, connected to how many other systems, and how much of the experience is built to order. This page sets out the real UK ranges and exactly what drives the figure, so you can read any quote, ours included, with clear eyes.
At the entry level, a few hundred pounds covers a self-built store on Shopify or a similar hosted platform: a paid theme, your own setup, and the platform's monthly fee on top. It genuinely works for a small, simple catalogue and a founder willing to do the work. It stops working when you need custom design, non-standard functionality, or integrations, because templates are built for the common case and every step away from it costs time that a few hundred pounds does not cover.
The middle of the UK market, roughly £5,000 to £20,000, is where most serious small and mid-sized stores sit. This band buys a properly designed store built around your brand and your products, a sensible catalogue and information architecture, the core integrations a real business needs, and a checkout and customer journey shaped to convert rather than accepted off the shelf. Managed Shopify builds tend to sit in the lower half of this range; heavily customised, headless or platform-migrated stores sit toward the top and beyond, where large catalogues, bespoke logic and multiple integrations are involved.
Rogue Logic builds bespoke ecommerce sites from £5,000 and states the numbers plainly. There is no setup fee hidden behind a form and no rate card you have to book a call to see. What follows is how the price is built, what pushes it up or down, and how we run a build once it starts. If you want the wider picture on website pricing generally, our web design cost page covers non-ecommerce builds too.
Ecommerce website cost, broken down.
Platform and build approach
Managed Shopify, WooCommerce or a bespoke build each carry a different cost shape. Shopify is faster to stand up and carries a monthly platform fee; a customised or headless build costs more up front and buys more control. The choice follows your catalogue, margins and how bespoke the experience needs to be.
Explore →Catalogue size and complexity
Product count, variants, options and how the catalogue is organised all feed the price. A small curated range on a clean structure is quick; thousands of SKUs with complex variants, bundles and merchandising rules take real time to build and to get right.
Design and brand work
A lightly themed store is cheaper than a distinctive, brand-led design built to convert. The more the look, layout and buying journey are made to order rather than adapted from a template, the more design and build time the store carries.
Explore →Integrations and systems
Payment providers, shipping and fulfilment, ERP or stock systems, email and CRM, subscriptions or marketplaces: every system the store has to talk to adds scope. A standalone shop is far simpler than one wired into the rest of your operation.
Bespoke functionality
Custom checkout logic, product configurators, membership or wholesale pricing, and anything beyond the platform's defaults is where cost climbs, because it is built and tested rather than switched on. We are candid about when a standard feature will do the job just as well.
Hosting, support and running costs
Beyond the build there is the ongoing cost of hosting, maintenance and platform fees. We offer managed hosting from £100 a month if you want us to run and look after the store, which is a separate, stated cost from the build itself.
Explore →The way we run Ecommerce website cost.
Free teardown of what you have
If you already sell online, we run a report on your current store and a strategist walks you through it. It shows what is holding conversion and performance back, and it is free rather than a sales pitch in disguise.
Scope, then a stated price
We map what the store actually needs to do: platform, catalogue, design, integrations and any bespoke logic, then quote against that scope. You see the number before you commit, not an estimate that quietly grows once the contract is signed.
Design around the buying journey
We design the store around how your customers actually buy, not a template's idea of it, with the checkout and key journeys shaped to convert. Senior people do the design work, so it is right rather than merely finished.
Build, integrate and test
The store is built on the agreed platform, wired into the systems it needs, and tested properly across devices, payment and fulfilment before it goes near a customer. No launching and fixing in public.
Launch with measurement in
We launch with clean analytics and conversion tracking in place, so from day one you can see what is selling and where buyers drop off, rather than guessing. Measurement is part of the build, not an afterthought.
Run it, or hand it over
You can take the store and run it yourself, or we host and maintain it from £100 a month. Either way you own the build, and there is no lock-in dressed up as support.
How we approach Ecommerce website cost.
Platform sets the starting point
Shopify, WooCommerce and bespoke builds carry very different cost shapes. A managed Shopify store is faster and cheaper to stand up and carries a monthly platform fee; a heavily customised or headless build costs more up front and buys more control. The right platform depends on your catalogue, your margins and how bespoke the buying experience needs to be.
What actually moves the number
Price tracks the real scope: how many products and variants, how custom the design is, which systems it has to talk to, and how bespoke the checkout and customer journey need to be. A small curated catalogue on a clean theme is a fraction of a large, integrated store with custom logic behind it.
Senior-led, no junior markup
Rogue Logic is four senior practitioners with roughly forty years of combined experience and no juniors. You are not paying agency overhead for account managers relaying work to someone cheaper. The person who scopes your store is the person who builds it, which is why fewer senior hours reach the same result.
Stated openly, no rate card behind a form
Bespoke ecommerce builds from £5,000, scoped against your actual requirements, with hosting from £100 a month if you want us to run it. One-off work is £119 an hour. Publishing the numbers is the point; most UK studios of this size quote privately.
What Ecommerce website cost puts on your desk.
Who prices your store, and how
Rogue Logic is the trading name of Bryley Ltd, a team of four senior practitioners with roughly forty years of combined experience across design, build and ecommerce. There is no junior delivery team and no account layer between you and the work. When we quote a number, it comes from the people who will build the store, not a sales desk incentivised to overscope. We recommend the platform your business actually needs, price against your real requirements, and would rather talk you out of functionality you will not use than sell it to you.
The person quoting is the person building
Your senior lead scopes the store and then builds it. There is no gap between the pitch and the delivery, which keeps the price honest and the store accountable to what was promised.
Priced against evidence, not a template
We scope from what your store genuinely needs to do, so the number reflects your real catalogue, integrations and design, not a one-size package with a margin baked in.
Honest about platform and scope
If a managed Shopify store will serve you better than a bespoke build, we say so. We recommend the approach that fits your business, not the one that bills the most.
Ecommerce website cost: common questions.
How much does an ecommerce website cost in the UK?
It ranges from a few hundred pounds for a self-built Shopify template to £15,000 or more for a bespoke store, with most serious small and mid-sized builds landing between £5,000 and £20,000. Managed Shopify builds tend to sit in the lower half of that; heavily customised or headless stores sit above it. Rogue Logic builds bespoke ecommerce sites from £5,000, priced against what your store actually needs to do.
How much does a Shopify website cost?
A self-built Shopify store can cost only the monthly subscription plus a paid theme, in the low hundreds of pounds, if you set it up yourself. A professionally built and customised Shopify store usually sits in the £5,000 to £15,000 range depending on design, catalogue and integrations, on top of Shopify's ongoing platform fee. We advise honestly on whether Shopify is the right platform for you before quoting.
Why do ecommerce website prices vary so much?
Because an online store is not a fixed product. The price depends on the platform, how many products and variants you sell, how custom the design is, how many other systems the store has to connect to, and how much bespoke functionality it needs. A small curated catalogue on a clean theme is a fraction of the cost of a large, integrated store with custom logic, and both are legitimately ecommerce websites.
Is Shopify or a bespoke build better value?
It depends on your business. Shopify is faster and cheaper to launch and carries a monthly fee, which suits many small and mid-sized retailers well. A bespoke or headless build costs more up front but gives more control over the experience and how it integrates, which pays off for larger catalogues or unusual requirements. We recommend the one that fits your business rather than the one that bills the most.
What are the ongoing costs of an ecommerce website?
Beyond the build there is hosting, maintenance and, on platforms like Shopify, a monthly platform fee and transaction costs. Budget for updates, security and support as well, because a store left untended degrades. Rogue Logic offers managed hosting and maintenance from £100 a month if you want us to run it, stated separately from the build cost so you can see exactly what you are paying for.
Does Rogue Logic charge a setup fee?
No. The build is scoped and quoted against your actual requirements, with the number agreed before work starts. There is no separate setup fee and no rate card hidden behind a contact form. If you want us to host and maintain the store afterwards, that is a stated monthly cost from £100, entirely separate from the build.
