E-commerce Website Cost UK — 2026 Pricing Guide

How much does an e-commerce website cost in the UK in 2026? Realistic ranges in 2026: £1,999–£5,000 for a specialist build, £5,000–£15,000 from a UK mid-tier agency, and £20,000+ for complex multi-region or B2B platforms. The figure mostly depends on product count, the level of customisation, and which payment and inventory systems you need to integrate.

This is the practical UK e-commerce website pricing guide. We’ve built shops for D2C brands, beauty retailers, food and drink, fashion, and B2B suppliers across the UK. Below is what each price tier delivers, the platform decisions that drive cost, and the hidden monthly fees that catch most UK shop owners by surprise.

UK e-commerce pricing by build tier

Platform choice drives 70% of the cost

Before any agency, the platform decision sets the budget. Three main routes for UK e-commerce:

1. Shopify (£25–£300+/month)

• Best for: D2C brands, solo founders, low-friction launch, drop-shipping
• Pros: Fastest to launch, payment processing built-in, vast app ecosystem, reliable
• Cons: Transaction fees (2% if you don’t use Shopify Payments), app costs add up, customisation requires Shopify-specific developers (£60–£120/hour)
• Realistic UK monthly cost: £25 plan + 3–5 apps (£10–£40 each) = £100–£300/month all-in

2. WooCommerce on WordPress (£30–£80/month)

• Best for: Brands that want full control, content-heavy SEO, complex pricing, no transaction fees
• Pros: 100% owned, no transaction fees, infinitely customisable, better SEO ceiling
• Cons: More setup work, you need a host who can handle e-commerce traffic, premium plugins occasionally needed
• Realistic UK monthly cost: £15–£40 hosting + £20–£40 in plugin licences = £30–£80/month

3. Custom-built platforms (£15,000+)

• Best for: B2B with complex pricing tiers, regulated industries, multi-region requirements, unique workflows
• Pros: Exactly fits your business; no platform compromises
• Cons: Build time 4–12 months, ongoing development costs, harder to find replacement developers
• Realistic UK cost: £15,000+ build, £500–£3,000/month ongoing dev retainer

What you get for £1,999 at the UK specialist tier

At our typical e-commerce build price of £1,999:

• Custom-designed WooCommerce shop on WordPress (full ownership)
• Up to 50 products configured with categories, attributes, variations
• Payment gateway integration — Stripe, PayPal, Klarna, ApplePay, GooglePay
• Shipping rules — by location, weight, or product class
• Tax setup — UK VAT including digital VAT compliance if applicable
• Mobile-first responsive design — mandatory for UK e-commerce (60%+ of traffic is mobile)
• Customer accounts — wishlists, order history, saved addresses
• Email transactional flow — order confirmation, shipping, abandoned cart recovery
• SEO foundation — schema, sitemaps, page speed optimisation, meta tags
• WordPress training — so you can add products and update content yourself

What pushes you to higher tiers: more than 500 products, multi-currency, B2B pricing tiers, custom integrations (CRM, ERP), bespoke checkout flows, or non-WooCommerce platforms.

Hidden ongoing costs for UK e-commerce

The build is half the story. Year-one running costs catch most UK shop owners:

On Shopify (typical small brand)

• Shopify Basic plan: £25/month = £300/year
• Apps (typically 3–6 essential ones): £30–£120/month = £360–£1,440/year
• Transaction fees (2% × £30k turnover): £600/year
• Theme licence (one-off or upgrade): £200
• Premium support / customisation hours: £200–£1,000/year
• Realistic Year 1 total: £1,660–£3,540 in platform costs alone

On WooCommerce (typical small brand)

• Managed WordPress hosting: £25/month = £300/year
• Premium plugins (e.g. WooCommerce Subscriptions, Stripe Pro, Advanced Shipping): £150–£500/year
• SSL: free with most UK hosts
• No transaction fees beyond Stripe/PayPal’s 1.4–1.9% + 20p
• Maintenance (DIY or light agency): £200–£600/year
• Realistic Year 1 total: £650–£1,400 in platform costs alone

WooCommerce is cheaper to run; Shopify is cheaper to manage. The right call depends on whether your bottleneck is cash or time.

E-commerce cost by product type

Red flags when getting UK e-commerce quotes

• “£500 full e-commerce site” — usually a template with no customisation, or work being subcontracted at a loss to a low-cost market
• No mention of payment gateway — Stripe vs PayPal vs Klarna integration is essential and should be explicit in the quote
• Locked-in hosting — some agencies build on platforms only they can host; you’re stuck
• No SEO baked in — schema markup, sitemap, page speed optimisation should all be in the base quote, not “extras”
• VAT handling not mentioned — UK shops above the £85k threshold need proper VAT setup including digital VAT compliance
• No training — if you can’t add products yourself, every change costs you

The ROI argument for proper UK e-commerce builds

The cheapest e-commerce build is rarely the cheapest e-commerce business. Consider:

• A poorly built shop typically converts at 0.5–1.5%
• A properly built shop converts at 2–4%
• On 1,000 monthly visitors at £40 average order, that’s £200–£600/month vs £800–£1,600/month in revenue
• The £4,000 difference between a cheap and proper build pays back in 1–4 months

Add SEO performance (better page speed and schema = more organic traffic) and the gap widens further.

What to do next

For most UK e-commerce businesses:

1. Decide between WooCommerce and Shopify based on your cashflow vs time constraints
2. Plan for around £100–£200/month in running costs after build
3. Budget £1,999–£5,000 for a specialist build, more if you need bespoke features
4. Insist on training so you can manage the shop yourself
5. Confirm SEO foundations are included, not extra

Shopify vs WooCommerce — the real cost at different revenue levels

Headline pricing is misleading. Below: total annual cost at four revenue levels.

Crossover point: ~£3,500-£5,000/month revenue. Below this, the platforms are roughly tied; above it, WooCommerce wins meaningfully on cost-per-sale.

UK VAT and tax considerations

Shopify Tax (UK)

Shopify Tax handles UK VAT automatically and accurately for 2026. It also handles MOSS (the system for EU customers) — though MOSS only applies to digital goods and B2C cross-border sales over thresholds.

WooCommerce + WP-Lister / Avalara / similar

WooCommerce needs a VAT plugin (free options exist; paid for advanced scenarios). Manual VAT setup is possible but error-prone.

VAT registration threshold

£85,000 UK turnover in a rolling 12-month period. Once you cross this you must register; many SMEs register voluntarily earlier to reclaim input VAT.

When neither WooCommerce nor Shopify is right

You’re selling a single product on subscription

Look at Cratejoy, Bold Subscriptions, or a custom-built site with Stripe Subscriptions. WooCommerce Subscriptions works but the overhead may not justify the cost.

You’re selling digital downloads only

Gumroad, Lemon Squeezy, Paddle, or Stripe direct. Avoid the e-commerce platform overhead for downloads.

You’re selling at high volume with custom logistics

BigCommerce, Magento Commerce, or custom builds become worth the investment above ~£500k/year revenue.

You’re selling B2B with complex pricing

Custom WooCommerce build with B2B-specific plugins (Wholesale Suite, B2BKing) typically outperforms Shopify B2B for UK businesses below enterprise scale.
