Ecommerce Website Cost in the UK: What Drives the Price
Three UK guides published in 2026 put an ecommerce website anywhere from £2,000 to £5,000+ for a basic shop to £15,000 to £92,500 for a 250-product agency build. The gap is scope: catalogue size, platform, integrations and who builds it. They are market readings, not quotes.

How much does an ecommerce website cost in the UK?
Three UK guides published in 2026 give ranges from £2,000 to £5,000+ for a basic online shop up to £15,000 to £92,500 for a 250-product build at an agency, depending on who builds it and what the scope includes. The spread is scope, not error. Treat them as readings of different jobs, not as a market price.

Why do ecommerce website cost estimates disagree so much?
Because they describe different shops. A template shop with a few products and one payment method is a small job; a catalogue with live stock, trade pricing and several shipping rules is a different one. The label “ecommerce website” covers both, and the range follows the scope behind it, not the label.
A shop also costs more than a brochure site for a structural reason: it takes money, holds stock data, calculates tax and shipping, and has to keep working under load. What an ordinary business website costs is covered separately; this guide takes only the drivers that belong to shops. If a build is mostly the systems behind the shopfront, ecommerce development is the closer description of the work.
Read every figure with its basis. All three publishers sell web work, none of the guides is a survey, and Opace states that its figures exclude VAT and come from a calculator. Check whether VAT is included, and which supplier type and catalogue size a number assumes, before comparing it with a quote.
The point
Check whether VAT is included, and which supplier type and catalogue size a number assumes, before comparing it with a quote.
What drives the cost of an ecommerce website?
Catalogue size and data quality, the platform, how many systems the shop must talk to, payment and tax set-up, shipping rules, migration from an old store, and how much design and content has to be created. These decide where a shop lands in any range, and a good quote prices each separately.
- Catalogue size and data quality. Hundreds of clean products imported from a spreadsheet are routine. Thousands with inconsistent attributes, variants and image names need cleaning and mapping first, and that work sits in the data, not in the product count.
- Platform and theme. A configured theme on Shopify or WooCommerce is a smaller job than a custom theme, and both are smaller than a headless or fully custom build. Shopify, WooCommerce or custom compares the routes.
- Integrations. Live stock, accounting, fulfilment and customer records are where most of the hidden effort sits. Whether the other system has a usable API matters more than its name, and where no suitable tool exists, custom CRM development may be part of the answer.
- Payments. Card payments, wallets and buy-now-pay-later options are straightforward to switch on. The cost is in handling failures properly: declined cards, abandoned payments, refunds and reconciliation against your accounts.
- Shipping and tax rules. Zones, carriers, weight and price bands, click and collect, and VAT on cross-border sales each add configuration and testing. The more rules, the more edge cases.
- Trade and B2B features. Customer-specific pricing, credit terms, minimum orders and quote requests are frequently the most profitable part of a retailer's business, and the worst served by standard themes.
- Design and content. Adapting a proven pattern costs less than designing a storefront from scratch. Product photography and descriptions are real costs when they do not already exist.
- Search readiness. Category architecture, filter handling and product templates are cheaper to build correctly than to retrofit, which is why ecommerce SEO belongs in the build brief.
- Support after launch. A shop needs updates, integration monitoring and payment checks, and the level of cover you choose changes the annual cost.
What do integrations, photography and copywriting add?
CloudSwitched's guide of 11 April 2026 prices common extras separately: shipping integration £300 to £1,500, inventory integration £500 to £5,000, email marketing integration £200 to £800, photography £500 to £2,500 per 50 products and copywriting £400 to £1,200 per 50 products. They are one publisher's ranges, and they show where a budget goes beyond the template.
| Item | Range (CloudSwitched, 11 April 2026) | What moves it |
|---|---|---|
| Shipping integration, for example Royal Mail or DPD | £300 to £1,500 | The number of carriers, whether labels and tracking are automated, and how many rate rules apply. |
| Inventory management integration | £500 to £5,000 | Whether the stock system has a documented API, how often stock must update, and how many locations hold it. |
| Email marketing integration | £200 to £800 | Which events sync, such as orders, abandoned baskets or consent, and how clean the customer list is. |
| Product photography | £500 to £2,500 per 50 products | Product type, the number of angles, and whether you shoot in-house. |
| Product copywriting | £400 to £1,200 per 50 products | Whether descriptions must be written from scratch or only edited, and how technical the products are. |
| ERP and CRM integration | No range given in that guide | Quoted case by case. The guide mentions them for large platforms without a price, and so should any honest article. |
What do platform subscriptions and payment fees cost?
Platform subscriptions and card fees are set by the vendors and change often, so the only reliable figure is the one on their own pricing page. Shopify's UK page, read in October 2026, lists plans from £19 a month on yearly billing, and Stripe's UK page lists 1.5% + 20p for standard UK cards. Both can change.
| Item | What the vendor's page shows (read October 2026) | What it means for the budget |
|---|---|---|
| Shopify Basic | £19 a month paid yearly, £25 paid monthly. Online card rate 2% + 25p; 2% on third-party gateways. | Introductory offers also appear on the page. Budget from the standard price. |
| Shopify Grow | £49 a month paid yearly, £65 paid monthly. Online card rate 1.7% + 25p; 1% on third-party gateways. | Higher plans trade a bigger subscription for lower per-sale fees. |
| Shopify Advanced | £259 a month paid yearly, £344 paid monthly. Online card rate 1.5% + 25p; 0.6% on third-party gateways. | Worth calculating once order volume is steady, not guessing. |
| Shopify Plus | From £1,800 a month, with no yearly option shown. Online card rate 1.3% + 25p; 0.2% on third-party gateways. | A different class of project. Not a default for a small retailer. |
| Stripe, standard UK cards | 1.5% + 20p per transaction (Stripe UK pricing page). | Charged on every sale by the provider, never by the developer. |
| Stripe, other cards | Premium UK cards 2.8% + 20p; EEA cards 2.5% + 20p; other international cards 3.15% + 20p; plus 2% for currency conversion on international cards. | Your customer mix changes the average fee. |
| WooCommerce | Opace's guide of 26 August 2026 notes the core software is open source with no licence fee listed. | The costs move to hosting, extensions, gateway fees and maintenance, which you or your supplier carry. |
| Worked example | Opace, 26 August 2026: £950 in processing fees on 1,000 successful £50 orders at Stripe's standard UK card rate. | Fees scale with sales, so they belong in the margin calculation, not the build quote. |
What does migrating an existing shop add to the cost?
Migration adds data work and risk. Products, customers, order history and every old URL have to be moved, mapped and checked, and the effort scales with catalogue size and data quality, not with how the old store was built. The larger cost of doing it badly is lost rankings, not the invoice.
No reliable pound figure is published for it. Opace's calculator, dated 26 August 2026, gives effort rather than price: 4 to 15.5 person-days for a standard profile of up to 100 products and 9 to 32 person-days for a larger one. Those are calculator outputs, but they show the shape of the problem: it grows with the catalogue and with how messy the data is.
A migration plan starts with a map of every old URL to its new home, a redirect for each, and an indexation check afterwards. Which moves put rankings at risk is covered in SEO for a website migration, and ask any supplier to show that map before the build begins, not after launch.
The point
A migration plan starts with a map of every old URL to its new home, a redirect for each, and an indexation check afterwards.
What does an ecommerce website cost to run after launch?
A shop has running costs that a brochure site does not: the platform subscription, card fees on every sale, app or extension licences, hosting if it is self-hosted, and maintenance and monitoring. Card fees scale with turnover and apps accumulate unnoticed, so both deserve a line in the first-year budget, not an afterthought.
CloudSwitched's guide of 11 April 2026 lists maintenance packages at £50 to £150 a month for a basic tier, £150 to £400 for a standard one and £400 to £1,000+ for a premium one, and plugin or app licences at £100 to £1,000 a year. They are one publisher's ranges; what matters is the categories, because a quote that mentions none of them is incomplete.
A shop needs more attention than a brochure site, because payments, stock feeds and integrations can fail silently. A website care plan at a sensible tier belongs in the first year's budget, and what maintenance costs at each tier sets out what the money buys. After launch, testing and improving the checkout is usually where the return is, and it cannot start before real traffic exists.
The point
A shop needs more attention than a brochure site, because payments, stock feeds and integrations can fail silently.
How do ecommerce website quotes differ in how they are priced?
Most ecommerce builds are quoted as a fixed price against a written specification, as a discovery phase followed by a build, or on time and materials. Each moves risk differently: fixed prices put it on the supplier, time and materials on you, and phased work splits it. The model matters as much as the number.
| Model | How it works | Suits | Watch for |
|---|---|---|---|
| Fixed price against a specification | The supplier writes down what will be built and quotes one price for it. | Shops with clear requirements and conventional features. | A thin specification. Anything missing returns as a variation. |
| Discovery first, then build | A short paid phase maps requirements, integrations and data. The build is then quoted from what it found. | Shops with integrations, trade pricing or messy data. | Paying for discovery and then finding the build price cannot be compared, because it was never put out to others. |
| Time and materials | You pay for days used against a rate, usually with an estimate. | Evolving shops and uncertain scope. | No ceiling unless one is agreed, and little incentive to be efficient. |
| Platform set-up package | A configured theme, standard pages and payment set-up for a stated catalogue size. | Small catalogues on Shopify or WooCommerce. | Anything off the standard path, such as integrations or custom shipping, priced outside the package. |
| Ongoing retainer after launch | A monthly arrangement for updates, monitoring and small changes. | Shops that trade continuously and cannot afford downtime. | A retainer that restricts what you can change, or that locks you in. See freelancer, agency or in-house for how supplier types differ. |
What should you ask for in an ecommerce website quote?
Ask what catalogue size the price assumes, which integrations, payment methods and shipping rules are in, what is excluded, who owns the accounts, and what support follows launch. A quote that answers those in writing can be compared. One that does not is a headline number, and the missing items turn up later as variations.
- What catalogue size and data condition does the price assume? Importing clean data and cleaning messy data are different jobs.
- Which integrations are in scope, and does each have a documented API? Get each one named.
- Which payment providers and methods are configured, and how are failures handled?
- Which shipping zones, carriers and tax rules are included? Edge cases such as islands, trade accounts and cross-border sales should be listed.
- What is excluded? Photography, copy, apps, subscriptions, hosting and training are the usual omissions. Insist on a list.
- How is migration handled, if there is one? Look for a URL map before the build, a redirect for every old address and an indexation check afterwards.
- Who will own the store account, domain, theme files and data at the end? They should be in your name.
- Who looks after the shop afterwards, and what is billed separately? How to choose a web development company lists the wider questions to put to any supplier.
What are the red flags in cheap and expensive ecommerce quotes?
In a cheap quote, the flags are a price that excludes payments, content, redirects and training, and a supplier who has only ever built on one platform. In an expensive one, they are a custom build recommended without trying a platform first, a high figure with no breakdown, and a retainer that locks you in.
| What you see | Why it is a flag | What to ask |
|---|---|---|
| A very low price for a shop with integrations, trade pricing or a large catalogue | The work has not been scoped. The missing items return as variations after you have committed. | What exactly is excluded, and what would each excluded item cost? |
| No mention of redirects when replacing an existing shop | Old URLs that stop working take their rankings with them. | Where is the URL map, and who checks indexation afterwards? |
| One platform recommended before anyone has seen your business | A supplier with one platform has a reason to say yes to it. | Would you tell me if this platform were wrong for me, and why? |
| A custom build for a business that fits a platform | Custom commerce carries ongoing engineering cost. It is rarely the right answer for a conventional retailer. | What specifically does this business need that a platform cannot do? |
| A high figure with no breakdown | You cannot tell whether you are paying for depth or overhead. | Can each driver, such as integrations, migration and design, be priced separately? |
| Every problem answered with an app or plugin | Apps are a subscription that grows without anyone deciding it should. | Which of these could be a few lines of code or removed altogether? |
| Account, domain or theme files held in the supplier's name | You may not be able to leave without rebuilding. | What is transferred on handover, and is it in my name? |
When is a new ecommerce website not the right spend?
When the problem is not the site. A rebuild will not fix weak demand, thin margins, a checkout that loses buyers or traffic that never arrives. If people already visit and leave, or the range cannot support the cost of winning customers, the money is better spent elsewhere first.
| Your situation | Why a new build will not fix it | Where the money is better spent |
|---|---|---|
| Visitors arrive but few buy | The cause is usually in the pages visitors land on and the checkout, not the platform. | Conversion optimisation on the existing shop. |
| Few people reach the shop at all | A new design does not create traffic. | Comparing the routes in SEO or PPC, and for product ads, Google Shopping management. |
| The current platform is sound but slow or dated | Re-theming or fixing performance is a far smaller job than a replatform. | A targeted speed and template fix on the platform you have. |
| You are selling a handful of products and testing demand | A full build commits money before demand is proved. | A simple configured shop on a hosted platform until sales justify more. |
| Margins cannot absorb card fees and acquisition cost | A prettier shop does not change the arithmetic. | Reviewing pricing, range and shipping, as the ecommerce and retail sector page discusses. |
| Product data is incomplete or inconsistent | Any platform will inherit the mess and the build will cost more because of it. | Cleaning the catalogue before commissioning anything. |
How does Prabhu Solutions quote an ecommerce build?
We scope it after looking at the store and the systems around it, and we publish no prices. What moves our quote is the catalogue, the platform, the integrations, the shipping and tax rules and whether a migration is involved, each set out separately so you can see where the money goes.
We recommend the platform after understanding the business rather than before, and we will say if a hosted platform is enough. Our delivery record to date is international rather than UK-based, and we say so plainly; the projects we have built show what we have made, not results we cannot promise.
If you hold a quote and want a second opinion on what it leaves out, or you are weighing platforms and want to know where the real cost sits, tell us about the shop and we will say honestly whether a rebuild is the right spend now.

How much does an ecommerce website cost in the UK?
Three UK guides published in 2026 range from £2,000 to £5,000+ for a basic shop to £15,000 to £92,500 for a 250-product agency build, the last excluding VAT. The gap is scope: catalogue size, integrations, platform and supplier type. Get a written scope before comparing any two quotes.
How much does a Shopify store cost to run?
Shopify's UK pricing page, read in October 2026, lists plans from £19 a month on yearly billing and £25 monthly, rising to £259 and from £1,800 for Plus, plus card fees. Apps, themes and custom work sit on top, so the plan fee is only part of what a Shopify agency would scope.
Is WooCommerce cheaper than Shopify?
Not automatically. WooCommerce's core software carries no licence fee, but hosting, extensions, security and maintenance fall on you, while Shopify bundles hosting into its subscription. Which is cheaper depends on order volume and who maintains it. The platform comparison works through the arithmetic.
Why are payment fees not in the build quote?
Because the payment provider charges them on every sale, not the developer. Stripe's UK page, read in October 2026, lists 1.5% + 20p for standard UK cards, with higher rates for premium and international cards. A sound quote names the provider configured and leaves the fees for you to budget.
Do I pay separately for photography and product descriptions?
Usually, if they do not already exist. CloudSwitched's 11 April 2026 guide gives photography at £500 to £2,500 per 50 products and copywriting at £400 to £1,200 per 50. On a large catalogue these can rival the template cost, so ask whether the quote assumes content you supply.
What does it cost to move my shop to a new platform?
No reliable pound figure is published. Opace's calculator, dated 26 August 2026, gives effort instead: 4 to 15.5 person-days for up to 100 products and 9 to 32 for a larger profile. The real drivers are catalogue size, data quality and the redirect map that protects rankings in a website migration.
Should I build a custom ecommerce website?
Rarely. Custom commerce suits a business model that does not fit a platform, such as configurable products or deep production integration, and it carries ongoing engineering cost. Most small and medium retailers are better served by a configured platform. Bespoke software is the honest route only when a platform genuinely gets in the way.
Why does a cheap ecommerce quote end up costing more?
Because the missing items return as variations: data import, redirects, payment edge cases, integrations, training and post-launch fixes. A low price that excludes them is a deposit on the real cost. Ask for a written list of exclusions, then price those items before comparing quotes.
