"How much does an eCommerce website cost?" is one of the most-asked questions we get from Suffolk and Ipswich businesses launching online, or moving on from a first attempt that isn't working. The honest answer ranges from "surprisingly little for a starter store" to "a proper investment for something serious — but with clear payback if the numbers add up." Here's an honest look at what eCommerce websites actually cost in the UK in 2026.
For context, we've built stores of every shape and size — small independent Shopify launches like Trailbound, larger WooCommerce catalogues, and custom eCommerce platforms with unusual product configurators or fulfilment workflows. The pricing landscape below reflects what we and other reputable UK agencies typically charge in 2026 — not Fiverr theme installs or marketplace rebrands.
The honest UK eCommerce pricing breakdown
Most legitimate UK eCommerce builds fall into one of four tiers:
- Starter Shopify (£1,500–£3,500): A customised Shopify theme, up to 30 products, standard payment setup, basic training, launch support. Best for owner-operators and small independent brands validating a product before major investment. 3–5 weeks.
- Custom-designed Shopify (£4,000–£10,000): The most common range for established UK brands. Custom design (not just a theme), 30–500 products, considered product-page UX, custom collection layouts, essential app integration (reviews, email, shipping), full training. 6–10 weeks.
- WooCommerce or larger Shopify build (£10,000–£25,000): Complex catalogues, sector-specific requirements, multiple integrations (accounting, warehouse management, ERP), custom checkout adjustments, higher-polish design and branding. 10–16 weeks.
- Custom or headless eCommerce (£25,000–£100,000+): Fully custom-coded stores, headless architecture (custom front-end with Shopify or a commerce API as back-end), complex product configurators, subscription models, unusual fulfilment logic. The realm of established brands scaling past £1M+ annual revenue.
Our own eCommerce development starts around £2,500 for small Shopify builds with typical projects landing in the £5,000–£15,000 range. Fixed-price quotes after discovery — no hourly billing surprises.
Platform choice: what actually matters
The eternal debate. Honestly, in 2026, the platform choice matters less than most guides suggest — but here's the practical decision framework:
- Shopify — the right answer for 80% of UK small-to-medium brands. Fast to launch, huge app ecosystem, reliable hosting handled for you, strong mobile checkout. Trade-offs: monthly platform fee (£30–£300 depending on tier), transaction fees on external gateways, app costs compound, more limited customisation on cheaper plans.
- WooCommerce — the right answer if you already run WordPress, want more content flexibility around the store, or have unusual product structures Shopify can't handle. Trade-offs: you're responsible for hosting, security patching, updates. Ongoing maintenance is a real cost.
- Custom / headless — the right answer for brands past £500K annual revenue with genuinely non-standard requirements (complex configurators, subscription mechanics, unusual fulfilment). Trade-offs: much higher initial cost, longer to launch, but no per-transaction platform fee and complete control over the customer experience.
- Squarespace / Wix commerce — fine for hobby stores and first-product validation. Not really where a serious business grows past £50K annual revenue.
The platform you pick matters less than the design quality, the checkout flow, and the fundamentals of running the shop. A well-run Shopify beats a badly-run custom build every time.
What actually drives the price
eCommerce quotes vary wildly for reasons that aren't obvious. The main cost drivers:
- Product count & variant complexity. 20 products, one variant each: easy. 500 products with size/colour/material variants: real data-entry and taxonomy work.
- Custom vs themed design. A customised theme (colour, fonts, hero image, basic layout) is dramatically cheaper than a bespoke design (custom product pages, custom collection layouts, unique interactive elements). Whichever you choose, be honest with yourself about which one it actually is.
- Integration count. Xero, ShipStation, Klaviyo, TrustPilot, Google Shopping, HMRC compliance, warehouse management. Each integration is real work.
- Checkout customisation. Shopify's standard checkout is fixed on Basic and Shopify plans. Full checkout customisation requires Shopify Plus (£2K+/month) or a custom build.
- Content migration. Moving 500 products with photos, descriptions and metadata from an old store to a new one is proper work — it's not free.
- Photography & content quality. Not usually a "web design" cost, but it dominates conversion. A store with poor product photos will underperform regardless of design.
What you should be paying for
A properly delivered eCommerce build should cover most of these:
- Discovery & specification — understanding your product, audience, competition, fulfilment reality and margin structure. You leave with a clear scope and fixed-price quote before anyone builds anything.
- Platform recommendation — the right answer for your stage, not the platform the agency happens to prefer. Ask them to justify the choice.
- Considered product page design — not just an image and price. Trust signals, delivery information, size guides, reviews, related products. Product pages are where conversion happens.
- Optimised checkout — as few fields as possible, mobile-first, guest checkout available, Apple Pay / Google Pay enabled.
- Payment integration — Stripe, Shopify Payments, or your preferred gateway, fully configured and tested with test transactions.
- Shipping & tax setup — UK VAT, EU thresholds, international shipping zones, courier integrations if needed.
- Email flow setup — order confirmation, dispatched, delivered, review request. Not sexy but essential.
- Analytics & tracking — Google Analytics, conversion tracking, Facebook / TikTok / Google Ads pixels if you're advertising.
- SEO foundations — product schema markup, structured collection URLs, proper meta descriptions, XML sitemap.
- Training & documentation — adding products, processing orders, refunds, updating content. Written docs your team can refer back to.
- Launch support — monitoring the first week, catching quick issues, small tweaks after real customer behaviour appears.
What you should never pay for
Red flags when comparing eCommerce quotes:
- "Custom eCommerce" that's a Shopify theme with your logo — some agencies sell theme customisation as "bespoke design". You'll spot it by the very low price and inability to show wireframes of your product pages specifically. Nothing wrong with themed builds — but pay theme prices, not custom prices.
- Hourly billing for the whole project — fine for post-launch changes and adhoc work. Dangerous for the initial build. Fixed-price with clear scope is the professional structure.
- "We can't say until we start" quote — anyone quoting a range like "£5K to £25K" without doing a discovery phase is either dodging accountability or preparing to scope-creep you. Insist on discovery first, then a fixed quote.
- Undisclosed app fees. Some agencies build stores that depend on paid Shopify apps (like £30–£100/month reviews, sliders, upsell tools) without warning you. Ask up front which apps the build will require and their monthly cost.
- Vague answers about hosting for WooCommerce — if it's WooCommerce you need to know exactly what hosting stack they're recommending, what it costs, and who's responsible for security patching and updates. Bad hosting is where most WooCommerce disasters start.
- Marketing services bundled unclearly — SEO, PPC and social advertising are separate services. Anyone bundling "SEO included" without clear scope is either up-selling something you don't need, or delivering nothing meaningful.
The five-year maths: Shopify vs custom
The comparison depends heavily on order volume. Let's say you're doing £500K annual online revenue. Indicative 2026 numbers:
- Shopify (Basic to Shopify plan): Platform £30–£80/month = £720/year. Shopify Payments transaction fees 1.5%–2.9% = £7,500–£14,500/year. Essential apps £100–£200/month = £1,500–£2,500/year. Initial build £5,000. Total year 1: roughly £15,000–£22,000. Five-year total (assuming revenue stays flat): £65,000–£95,000.
- WooCommerce: Hosting £50–£200/month (for £500K revenue you want proper hosting) = £1,200/year. Transaction fees on Stripe 1.4% + 20p = £7,000–£10,000/year at that revenue. Essential plugins £500–£1,000/year. Initial build £12,000. Total year 1: roughly £20,700. Five-year: £55,000–£65,000. Cheaper long-term but higher maintenance overhead.
- Custom / headless: Hosting £150–£500/month = £3,600/year. Transaction fees on Stripe direct £7,000–£10,000/year. Initial build £40,000+. Total year 1: roughly £51,000. Five-year: £90,000–£120,000. Only makes financial sense if you're growing fast and Shopify's per-transaction fees are the bottleneck.
The rough rule of thumb: below £500K annual revenue, Shopify almost always wins on economics. Between £500K and £2M, WooCommerce and Shopify Plus become interesting. Above £2M with clear technical needs, custom builds start to make sense.
What about cheap eCommerce offers?
You'll see £500 eCommerce offers on Fiverr, Upwork, and via cold-email agencies. What you actually get:
- Theme installation with logo swap — a bought Shopify theme with your logo and colours. No custom design, no considered UX, no discovery. Fine if you know exactly that's what you're buying.
- Offshore development on a template — can produce a working store, but typically without UK-specific tax/VAT setup, GDPR-compliant privacy handling, or optimisation for UK payment methods. Result usually needs meaningful rework.
- Genuine scams — collect deposit, deliver nothing usable, disappear. Rarer than in software, but not unheard of.
For UK businesses building anything they expect to be commercially serious, the cost of fixing a bad build is almost always higher than commissioning it properly first time. Especially true for UK tax, GDPR, shipping and payment gateway configuration.
The bottom line
For most UK businesses launching or replatforming eCommerce in 2026, expect to budget between £4,000 and £15,000 for a proper custom-designed Shopify store or small WooCommerce build. Themed Shopify starter stores can come in at £1,500–£3,500. Complex WooCommerce catalogues run £15,000–£25,000. Custom or headless builds start at £25,000 and scale up quickly.
What you should absolutely expect: a discovery phase, a fixed-price quote against clear deliverables, an agreed delivery schedule, transparent disclosure of all recurring app and platform costs, UK tax/VAT setup, GDPR-compliant privacy, mobile-first checkout, and training so your team can add products and process orders without calling you every week.
