How much does an e-commerce website cost in the UK?.

A UK e-commerce website costs anywhere from £30 a month to £30,000, which is why the question deserves a proper answer. For a Welsh small business the realistic bands are: build it yourself on Shopify for roughly £25 to £40 a month, buy a template store for £1,400 to £2,000, or commission a professionally designed store for £3,000 to £8,000. This guide breaks down where the money goes, the running costs nobody budgets for, and when you should not build a shop at all.

The quick answer

Route	Typical cost	Who it suits
DIY on Shopify or Wix	£25 to £40 a month, your time	Testing whether anyone will buy
Template store	£1,400 to £2,000 one-off	Small catalogues, simple needs
Professional Shopify build	£3,000 to £8,000	Businesses serious about selling online
Fully custom platform	£10,000 and up	Large catalogues, complex integrations

Two businesses can both "have an online shop" and have spent wildly different amounts. The difference is rarely how the shop looks on day one; it is how fast it loads, how well it converts visitors into buyers, and whether Google sends it any traffic without paid ads.

Shopify's own fees, explained

Whoever builds your store, if it runs on Shopify you pay Shopify. As of 2026 the entry plan is roughly £25 a month billed annually, with mid tiers around £65 and advanced plans considerably more. On top of that come card processing fees, typically around 2% on the entry plan, falling as you move up tiers.

Then there is the quiet one: apps. The Shopify app store makes it very easy to add reviews, bundles, subscriptions and popups at £5 to £30 a month each, and stores routinely end up paying more for apps than for Shopify itself. A well-built store needs far fewer apps, because the common jobs are handled properly in the build.

What a professional build actually adds

A DIY store and a professional one run on the same platform, so what does the £3,000 to £8,000 buy? Four things that move sales:

• Design around your products, not a theme's demo content. Your photography, your categories, your customer's route to checkout.
• Speed. Standard themes ship code for every feature they support; a tuned build carries only what your shop uses. Slow stores lose buyers before the product page loads.
• Search visibility. Product and category pages structured so Google understands them, which is where free, repeat traffic comes from.
• Conversion detail. Trust signals, delivery clarity, a checkout with no surprises. Small percentages on every visit compound into real revenue.

Our own approach at WebDev Wales is Shopify wrapped in a custom build: Shopify's checkout and stock management underneath, a custom-coded storefront on top, so you get the platform's reliability without the template weight. For the design side of that decision, including when a shop is the wrong answer entirely, see our guide to ecommerce website design in Wales.

The build is half the cost of an online shop. The other half is everything that keeps it selling.

What about WooCommerce? The other cost model

The other route you will be quoted is WordPress with WooCommerce, and its cost shape is the reverse of Shopify's: the software is free, and everything around it is not. You pay for hosting good enough to run a database-driven store (£15 to £50 a month for anything reliable), for the premium plugins that handle what Shopify includes (subscriptions, advanced shipping, proper reporting routinely add £100 to £300 a year each), and, the cost nobody prices in, for the developer time to keep a stack of independently updated plugins from breaking each other. Security sits on you too: WooCommerce stores are self-hosted, so the updates, backups and breach risk are yours in a way Shopify's hosted checkout never is.

WooCommerce earns its keep when you need something Shopify genuinely cannot do, or when a business already lives in WordPress. For a typical Welsh small business starting a store, the total cost of ownership over three years is usually similar or higher, with more of it spent on keeping the thing running rather than selling. It is why our own builds sit on Shopify's engine rather than a plugin stack.

A worked example: a 40-product store, year one

Numbers make the bands real. Take a Welsh business putting a 40-product range online properly, with a professional build at the bottom of the serious range:

Item	Year-one cost
Professional build (one-off)	£4,000
Shopify entry plan (£25 × 12)	£300
Two genuinely needed apps (£15 × 12)	£180
Maintenance plan (£39 × 12)	£468
Product photography (one day)	£300 to £500
Year-one total	roughly £5,300 to £5,500

Payment fees come out of sales rather than the budget, at roughly 2% on entry plans. Against that spend, the store needs to clear about £450 a month in sales it would not otherwise have made to cover itself in year one, and year two runs at under £1,000 because the build is paid for. That is the honest arithmetic to take into the decision: not "can we afford a store" but "do we believe in £450 a month of online demand". If the answer is no, the next section matters more than any price.

The costs nobody budgets for

Every e-commerce quote conversation eventually hits the same forgotten items:

1. Product photography. Buyers cannot pick your products up; the photos do the selling. Budget for it properly or the smartest build will underperform. It is why we offer website photography alongside builds.
2. Product descriptions. Someone has to write them, and copied manufacturer text hurts both conversion and search rankings.
3. Payment fees. Around 1.5% to 2.5% of every sale, forever, whichever provider you use.
4. Delivery and returns. Not a website cost, but the policies must exist before the store can launch honestly.
5. Keeping it running. Updates, backups, monitoring and changes. Our maintenance plans cover this from £39 a month; store owners doing it themselves usually stop after month three.

What it costs to run each month

A realistic monthly picture for a small Welsh store: the platform at £25 to £65, a handful of genuinely needed apps at £10 to £30, maintenance at £39 to £99, and payment fees scaling with sales. Call it £75 to £200 a month for a properly run store, before marketing. Anyone who tells you an online shop is a one-off purchase has not run one.

When you should not build a shop

Honesty first: not every business needs e-commerce. If you have a handful of products and no proof anyone will buy online, start on a marketplace or a simple site with an enquiry form and take payment over the phone. If your products sell on inspection, like the garden buildings at Bramwood Timber, a quote builder converts better than a checkout, which is exactly what we built them. The time for a real store is when you have products people reorder, post easily, and search for by name.

What we charge in Wales

Our e-commerce builds are quoted per project and sit in our Bespoke tier, from £4,000 +VAT. That covers the custom storefront, Shopify setup, product and category structure, speed and search foundations, and the monthly plan afterwards. Every price is agreed before work starts, and everything you have read above gets discussed honestly in the first call, including whether you need a store at all.

The bottom line

Budget £25 to £40 a month to prove the idea yourself, £3,000 to £8,000 for a store built to sell, and £75 to £200 a month to run it properly. The most expensive mistake in e-commerce is not overpaying for a build; it is spending anything on a shop nobody asked for. Prove demand first, then build it right.
