The UK ecommerce market is the third largest in the world, and online retail now accounts for around 28% of all UK retail sales, according to the Office for National Statistics. For any small business selling products, the ecommerce platform you build on directly affects how fast you can grow, how much you pay per sale, and how well your shop ranks in Google.
This guide covers five platforms that UK small businesses commonly consider: WooCommerce, Shopify, PrestaShop, OpenCart, and Weebly. Each is assessed on pricing, ease of use, ecommerce features, SEO, and long-term suitability with an honest verdict on each.
Quick Comparison
| Platform | Type | Starting Cost | Transaction Fees | Ease of Use | Best For |
|---|---|---|---|---|---|
| WooCommerce | Free plugin (WordPress) | Free + hosting ~£5–£15/mo | None from platform | Moderate | Most UK small businesses |
| Shopify | Hosted SaaS | £25/mo (Basic) | 2% if not using Shopify Payments | Easy | Fast setup, product-focused stores |
| PrestaShop | Free open-source | Free + hosting ~£5–£30/mo | None from platform | Moderate/Hard | Mid-sized stores, international sellers |
| OpenCart | Free open-source | Free + hosting ~£5–£15/mo | None from platform | Moderate | Developer-led, multi-store setups |
| Weebly | Hosted (declining) | Varies (Square plans) | Varies by plan | Easy | Not recommended for new builds |
What Matters in an Ecommerce Builder
Before comparing platforms, it helps to be clear about what actually affects your business. These are the factors that matter most for UK small ecommerce businesses.
- Transaction fees. Some platforms charge a percentage of every sale. On a busy store, this adds up fast.
- Ownership and data control. Hosted platforms control your store. Open-source platforms give you full ownership which matters for GDPR and long-term flexibility.
- SEO capability. Can you customise URLs, meta data, structured data, and site speed? These directly affect your Google rankings.
- UK payment gateways. Does the platform support Stripe, PayPal, and UK-specific processors without extra cost?
- VAT and tax handling. UK stores need accurate VAT calculation across product categories and delivery zones.
- Scalability. Will the platform still work well when you have 500 products and 1,000 orders per month?
- Developer availability. If you need help, how easy is it to find a UK developer who knows the platform?
1. WooCommerce — Best Overall for UK Small Businesses
WooCommerce is the world’s most widely used ecommerce platform. It powers over 4.5 million active stores globally, holds around 33% of the global ecommerce market by store count (StoreLeads), and has over 8 million active installations, according to the WordPress plugin directory. The UK is the second largest WooCommerce market after the United States, with around 171,000 to 247,000 stores depending on the data source.
WooCommerce is a free plugin that runs on WordPress. The software costs nothing, and crucially, WooCommerce charges no transaction fees of its own. Your payment gateway (Stripe, PayPal, or others) charges their standard processing rate, typically 1.4% + 20p for European cards via Stripe, but WooCommerce takes nothing on top. For a business processing significant volumes, this difference against platforms that charge transaction fees is meaningful.
Because WooCommerce sits inside WordPress, your store inherits WordPress’s exceptional SEO capability. You have full control over product URLs, meta data, structured data, image alt text, and page speed. Combined with free SEO plugins like Yoast SEO or Rank Math, this makes WooCommerce the strongest ecommerce option for businesses investing in organic search rankings. For UK stores selling jewellery, furniture, pet products, or niche items where content marketing and Google rankings matter, this is a genuine competitive advantage.
WooCommerce supports UK VAT rates, Royal Mail and major courier integrations, Stripe UK, PayPal, and virtually every UK payment processor via extensions. The extension library covers subscriptions, bookings, product bundles, B2B wholesale pricing, and much more.
The main trade-off is setup complexity. WooCommerce requires you to configure tax settings, shipping zones, payment gateways, and security from the outset. It is not as instant as Shopify. Most businesses find it worthwhile to have a developer set it up correctly rather than doing it themselves from scratch. Our WooCommerce website design service covers the full build from store setup and payment configuration to product import and SEO foundations.
Pros
- Free plugin with no platform transaction fees
- Full ownership of your store, data, and customer records
- Best-in-class SEO capability via WordPress
- Largest ecommerce community and extension ecosystem globally
- Supports all major UK payment gateways
- UK VAT, Royal Mail, and major courier integrations available
- Scales from a 10-product shop to a 10,000-product catalogue
- Large pool of UK WooCommerce developers and agencies
Cons
- Requires WordPress, not a standalone platform
- More setup than hosted platforms like Shopify
- You manage hosting, updates, and security
- Performance requires good hosting and proper optimisation
- Some premium extensions carry additional costs
2. Shopify — Best for Fast Setup and Simplicity
Shopify is the most popular dedicated ecommerce platform globally, with a 27–30% share of the ecommerce software market. It is fully hosted, Shopify manages servers, security, updates, and backups, so you focus entirely on running your store. Most merchants can have a working online shop live within a day.
The UK pricing starts at £25 per month on the Basic plan (monthly billing), dropping to approximately £19 per month on annual billing, per Shopify’s UK pricing page. This includes an online store with unlimited products, abandoned cart recovery, discount codes, and two staff accounts.
Payment processing through Shopify Payments costs 2.0% + 25p per transaction for UK merchants. If you use an alternative payment gateway, Shopify charges an additional 2% transaction fee on top of your gateway’s rate on the Basic plan. This matters for businesses with high order volumes at £50,000 annual revenue, that 2% fee adds £1,000 on top of your other costs. Moving to the Grow plan (£65/mo) reduces this to 1%, and the Advanced plan removes it entirely.
Shopify’s app store has over 8,000 integrations. Many of the most useful add-ons like advanced reporting, loyalty programmes, subscription billing, detailed reviews carry additional monthly fees. The real monthly cost of a fully configured Shopify store is often considerably higher than the subscription fee alone.
Where Shopify genuinely excels is ease of use, reliability, and its in-person selling capability through Shopify POS. For a business that also sells at markets, pop-ups, or a physical shop, the ability to unify online and offline inventory in one system is a strong advantage. Our Shopify website design service covers custom store builds, theme development, and app configuration.
Pros
- Fastest route to a professional online shop
- Fully hosted — no server or security management
- Strong UK payment support: Shopify Payments, Stripe, PayPal
- Shopify POS for unified online and in-person selling
- Built-in VAT tools and multi-currency support
- Excellent uptime and performance reliability
- 24/7 customer support
Cons
- 2% transaction fee on Basic plan if not using Shopify Payments
- App costs can escalate quickly beyond the subscription fee
- You do not own the platform, Shopify can change pricing at any time
- Content and blogging tools are basic compared to WordPress
- Migrating away later is time-consuming
- More expensive than WooCommerce for businesses with growing revenue
3. PrestaShop — Free Open-Source with Strong Ecommerce Features
PrestaShop is a free, open-source ecommerce platform that has been used to build over 300,000 online stores across more than 190 countries. The core software carries no licensing fee and no platform transaction charges. It was built specifically for ecommerce from the ground up. Unlike WooCommerce, which adds selling capability to WordPress, PrestaShop’s entire architecture is designed around running an online shop.
Out of the box, PrestaShop includes strong product management tools, multi-language and multi-currency support, native VAT configuration, advanced SEO controls (customisable meta data, canonical URLs, structured URLs), and a built-in affiliate and loyalty module. For businesses selling internationally or managing large, complex product catalogues, these native capabilities are a meaningful advantage.
PrestaShop’s marketplace offers over 2,400 modules covering payment gateways, shipping carriers, marketing tools, and reporting. Many essential functions like advanced shipping rules, specific payment processors, detailed analytics require paid modules, which can add considerably to the overall cost of running a PrestaShop store.
The platform has a steeper learning curve than WooCommerce or Shopify. Setting up a PrestaShop store correctly requires either significant technical confidence or a developer. PrestaShop also now offers a hosted version — PrestaShop Edition — starting at €24 per month billed annually, which includes managed hosting and pre-configured settings for merchants who want to avoid the technical setup.
For UK small businesses, developer availability is worth considering. The PrestaShop community and developer pool in the UK is notably smaller than WordPress and WooCommerce. Finding experienced PrestaShop developers for ongoing support is harder than finding WooCommerce developers.
Pros
- Core software is completely free
- Built specifically for ecommerce from the ground up
- Strong native multi-language and multi-currency support
- Advanced SEO controls built in to the core
- Good product and catalogue management tools
- Over 2,400 marketplace modules
- Hosted version available for non-technical users
Cons
- Steep learning curve, developer expertise recommended
- Essential features often require paid modules
- Smaller UK developer community than WooCommerce or Shopify
- Weaker content and blogging tools than WordPress/WooCommerce
- Less suitable for businesses relying heavily on content marketing for SEO
4. OpenCart — Lightweight, Free, and Developer-Friendly
OpenCart is a free, open-source ecommerce platform built on PHP. The core software has been downloaded over 10 million times since its launch and powers stores in more than 200 countries. Like WooCommerce and PrestaShop, it charges no licensing fees and no transaction fees of its own.
OpenCart’s strengths are its lightweight architecture and multi-store capability. A basic OpenCart installation uses around 50MB of disk space and runs efficiently on modest shared hosting. The multi-store feature — managing several separate online shops from a single admin dashboard is built into the core, whereas in WooCommerce it requires additional configuration. For agencies or businesses running multiple product brands, this is a practical advantage.
The OpenCart marketplace has over 13,000 extensions covering payment gateways, shipping, SEO tools, marketing, and design themes. It supports 40+ languages natively and integrates with major UK payment processors including PayPal, Stripe, Klarna, and SagePay.
The honest limitation in the UK market is developer availability. OpenCart peaked in popularity around 2015 to 2018. Since then, merchants have migrated steadily towards Shopify and WooCommerce, and the development community has shrunk accordingly. Finding experienced OpenCart developers for ongoing work is genuinely difficult in Western markets, as noted by independent platform reviews. The codebase has also been criticised for feeling dated compared to more modern frameworks.
OpenCart’s version 4.x, released in 2022, brought a modernised admin interface and improved performance. The hosted OpenCart Cloud version is available from $59 per month for those who prefer a managed setup.
Pros
- Free and open-source, no platform fees or transaction charges
- Lightweight, runs well on modest shared hosting
- Multi-store management built in to core
- 13,000+ marketplace extensions
- Supports 40+ languages natively
- Clean, intuitive admin interface for daily operations
Cons
- Shrinking community, finding UK developers is harder than WooCommerce
- Some extensions are outdated or poorly maintained
- Platform is no longer on an upward growth trajectory
- Codebase considered dated compared to modern PHP frameworks
- Weaker SEO and content capability than WordPress/WooCommerce
- Extension compatibility issues between major versions are common
5. Weebly — Not Recommended for Ecommerce
Weebly was once a popular website builder with integrated ecommerce. Square acquired it in 2018 for $365 million. Since then, the platform has received no significant feature development. The themes are the same as they were in 2018. The ecommerce tools have not evolved. Bugs reported by users are going unfixed.
Square has been actively directing new users to Square Online rather than Weebly, and the Weebly community forum has been closed and merged into Square’s forum. Weebly’s own support page previously stated it could only commit to supporting the Weebly editor until a specific date, and users attempting to migrate from Weebly to Square Online cannot transfer their site directly, they must build a new one from scratch.
For any UK small business building a new ecommerce store, Weebly presents a clear platform risk. The ecommerce features are frozen relative to competitors that have added AI tools, improved mobile experiences, expanded payment options, and modernised their interfaces. Building a business on a platform in maintenance mode is a significant risk when you depend on future feature development, security updates, and ongoing support.
What it still offers
- Simple drag-and-drop editor
- Integration with Square’s payment processing
- Low entry price point
Significant concerns
- No new features or themes since 2018
- Square is migrating users to Square Online, platform future uncertain
- Bugs being reported without fixes
- Cannot migrate site directly to Square Online, must rebuild
- Community forum closed
- SEO and ecommerce tools far behind current competitors
Which Platform Should You Choose?
Choose WooCommerce if:
- You want no platform transaction fees and full ownership of your store.
- SEO and content marketing are part of your growth strategy.
- You already use WordPress or plan to build a content-rich site alongside your shop.
- You sell physical products, digital downloads, or services — WooCommerce handles all three well.
- You want to sell through a professionally built ecommerce store on a platform with the largest developer pool in the world.
Choose Shopify if:
- You want the fastest route to a working online store.
- You also sell in person and need unified POS and online inventory.
- You prefer a fully managed platform where hosting and security are handled for you.
- You are comfortable with a monthly subscription and potential app costs.
Choose PrestaShop if:
- You manage a large or complex product catalogue.
- You are selling internationally and need strong native multi-language and multi-currency support.
- You have access to a developer with PrestaShop experience.
Choose OpenCart if:
- You need to manage multiple separate stores from one admin dashboard.
- You have a developer with OpenCart experience already.
- Low hosting overhead and a lightweight codebase are priorities.
Avoid Weebly for ecommerce.
There is no scenario in which we would recommend building a new ecommerce store on Weebly in its current state. The platform risk is too significant.

What is the best ecommerce website builder for small businesses in the UK?
WooCommerce and Shopify are the two strongest options for UK small businesses. WooCommerce is best for businesses prioritising SEO, data ownership, and long-term cost control. Shopify is best for businesses that want the fastest setup and a fully managed platform. PrestaShop and OpenCart are solid free alternatives for more technical users. Weebly is not recommended.
Is WooCommerce or Shopify better for UK small businesses?
WooCommerce has no platform transaction fees, gives you full data ownership, and integrates with WordPress for content marketing. Shopify is faster to launch and fully managed, but charges a 2% transaction fee on its Basic plan unless you use Shopify Payments. For long-term growth, WooCommerce is typically better value for most UK small businesses.
Is PrestaShop free?
The core PrestaShop software is free to download with no licensing fees or monthly platform charges. You pay for hosting and a domain, and many useful features require paid modules. A hosted version (PrestaShop Edition) is also available from €24 per month billed annually.
Is OpenCart suitable for UK small businesses?
OpenCart is free, capable, and good for multi-store setups or businesses with developer access. However, finding UK OpenCart developers is harder than finding WooCommerce or Shopify developers, and the platform’s community is smaller than it was. For most UK small businesses, WooCommerce is a more practical starting point.
Is Weebly still a good ecommerce platform?
No. Weebly has had no significant ecommerce development since Square acquired it in 2018. Square is directing new users to Square Online instead. Weebly’s themes are outdated, bugs are unfixed, and its future as a platform is uncertain. It is not recommended for any new ecommerce build.
