How Much Does an Ecommerce Website Cost in the UK?

An ecommerce website in the UK costs from around £25 a month in platform fees if you build it yourself, roughly £2,500 to £8,000 with a freelancer, and £5,000 to £25,000 or more with an agency, according to published 2026 UK pricing. Our ecommerce builds start from £5,000. The spread is enormous because “ecommerce website” covers everything from twelve products and a card reader to a catalogue wired into a stock system. What you are really buying is the number of awkward problems somebody else solves for you.

Below is what moves the number, what the quote usually leaves out, and how to brief the job so the prices you get back can actually be compared.

What actually drives the price

Design is rarely the expensive part. These are:

• Number of products, and how they vary. Fifty simple products are easier than five products in nine sizes and four colours. Variants multiply the work in the build and in the photography.
• Where your stock lives. If stock is counted in a spreadsheet, the site is the only system. If it lives in an accounts or warehouse package that the site must stay in step with, that integration is often the single biggest line on the quote.
• Shipping rules. Flat rate is simple. Weight bands, zones, offshore surcharges and click and collect are each a small project.
• Trade pricing. Customer-specific prices, minimum orders or account applications turn a shop into a system.
• Photography and copy. The most underestimated cost by a distance. A product page is nothing without a decent photograph and a description, and multiplying that by your catalogue is where budgets quietly go.

The three routes

None of these is the right answer in general. A small shop built well on a platform beats a badly specified agency build at four times the price, and we would say so before quoting.

The costs that do not appear on the quote

The build price is the part everybody compares. These are the ones that decide whether the shop is affordable to run:

• Platform fees, monthly, if you are on Shopify or similar.
• Transaction and card fees on every order, which is the cost that scales with your success.
• Apps and plugins. Reviews, subscriptions, advanced shipping and email tools are mostly monthly subscriptions, and four or five of them add up to a real number.
• Hosting and maintenance if you are on WooCommerce, where the upkeep is yours rather than the platform’s.
• Photography, whenever you add a product line.

Work out the monthly running cost before you sign anything, because a cheap build with expensive running costs is the more painful of the two mistakes.

What we would not pay for

Some of the most expensive items on an ecommerce quote are the ones least likely to earn their money back in the first year.

• A custom checkout. Use the platform’s. It is more tested than anything built to order, and it is the one page where an unusual experience costs you sales.
• A bespoke design for every product template. One good product template applied consistently outperforms four.
• A loyalty scheme at launch. Loyalty schemes reward repeat customers. Get some first.
• A mobile app. Almost never justified for a small shop. Your mobile site is the app.

How to brief it so the quotes compare

Most people ask three companies for a price on “an ecommerce website” and get three numbers that cannot be compared, because each has assumed something different. Send everybody the same short brief instead:

1. How many products, and how many variants each.
2. Where the stock lives now, and whether the site must stay in step with it.
3. Your shipping rules, written out in full, including the awkward ones.
4. Whether you need trade or account pricing.
5. Who is supplying photography and product descriptions.
6. What you want to be able to change yourself afterwards.

That last one separates the quotes more than anything else. A site you cannot update without ringing somebody is cheaper to build and considerably more expensive to own.

Where the money is better spent

One thing worth saying, because it rarely gets said by the people selling the build. Plenty of shops that are not selling do not have a build problem. They have a traffic problem, or product pages that do not answer the questions a buyer has, and a rebuild fixes neither.

If you already have a shop that is getting visitors and not converting, that is a different job and usually a cheaper one. It is worth being sure which problem you have before spending a build budget on it. We look at this in why a site can get traffic and no enquiries.

Common questions

How much do small business owners actually pay for a website?

For a straightforward brochure site, considerably less than for a shop, because none of the stock, payment or shipping work applies. We have broken the general case down in what a website costs in the UK. An ecommerce build is usually a multiple of that figure rather than an increment on it.

How much should a ten page website cost?

Page count is a poor way to price a website and a worse way to buy one. Ten simple pages using one template is a small job. Ten pages with a booking system, a members area and a stock feed is not. If a quote is priced per page, ask what happens when a page turns out to need something the others do not.

Is Shopify cheaper than WooCommerce?

Shopify usually costs less to start and more to run, because the monthly fee and the app subscriptions continue forever. WooCommerce usually costs more to build and less to run, but the maintenance is your responsibility. Over three to five years they tend to converge, so decide on the fit rather than the total. Our comparison of the two goes through it properly.

What is the cheapest way to sell online?

A marketplace or a social selling channel, by some distance, because you pay commission rather than build costs. The trade is that you are renting somebody else’s audience and their rules, and you cannot take the customer relationship with you. It is a sensible way to test whether the products sell before committing to a shop.

How long does an ecommerce build take?

Rarely the thing that holds it up. The build is usually waiting on product data, photography and shipping decisions, all of which sit with the client. Shops that launch on time are the ones where that material was ready before the build started.

If you want a straight answer on yours

If you tell us the six things in the brief above, we can tell you roughly what it should cost, including when the answer is that you do not need what you think you need. Our ecommerce work is here, and if you would rather we just looked at what you have, that is what we are here for.
