Best Ecommerce Platform in the UK: How to Choose for a Small Shop

If you're looking for the best ecommerce platform UK small shops can rely on, the honest answer is the one whose total cost and features fit how you actually sell, not the one at the top of a list. For a shop with a handful of products, Square Online or Wix is usually enough. For a growing catalogue with variants, Shopify or ShopWired are the strongest all-rounders, and ShopWired's built-in Royal Mail and trade-account features suit UK sellers in particular. If you want to own everything and can manage hosting, WooCommerce is the flexible choice.

The quick way to decide: work out what kind of shop you are (below), compare the real yearly cost in pounds, including card fees, and check the UK-specific details that listicles skip, such as VAT, Royal Mail and trade customers. Every price here was checked in October 2026 and is linked to its source.

The best ecommerce platform for a small business in the UK depends on your shop type

Most "top 10" lists rank platforms as if every shop were the same. They aren't. Start with the shape of your business.

A few products, low volume (crafts, a single product, a side business)

You need a tidy shop, card payments and low fixed costs. Square Online has a free plan where you only pay card fees, and Wix or Squarespace give you a nicer-looking site for a small monthly fee. Don't pay for features like multi-currency or advanced reporting yet.

A catalogue with sizes, colours and stock to track

Variants, stock levels, discount codes, abandoned-cart emails and shipping rules matter here. Shopify and ShopWired are built for this. WooCommerce can do it too, but you (or someone you pay) look after the hosting, updates and security.

Trade and wholesale (B2B) customers

If you sell to shops or businesses at trade prices, check for trade accounts, price lists and invoice payment. ShopWired includes trade accounts on its Advanced plan and above and offers them as a £10/month add-on on Essentials (ShopWired pricing). On other platforms this often means paid apps or a higher plan.

Subscriptions, bookings, or anything unusual

Subscription boxes, made-to-order products, custom quotes, or stock shared with a physical shop are where off-the-shelf platforms start to need several paid apps stitched together. That is the point to price up a store built around how you sell (more on that below).

UK ecommerce platforms compared in £ (October 2026)

Prices below are the entry plan that can sell online, as listed on each platform's UK page in October 2026, or, for Wix and Squarespace, in a UK pricing review updated in 2026. "Annual" means the monthly equivalent when you pay for a year up front.

Platform	Entry selling plan	Platform fee on sales	UK card processing (own payments)	Good to know
Shopify	Basic: £25/mo monthly, £19/mo annual	0% with Shopify Payments; 2% with a third-party gateway on Basic	2% + 25p online (Basic)	Biggest app ecosystem; Grow plan £65/mo monthly
ShopWired	Essentials: £34.95/mo monthly, £31.46/mo annual	0% on external gateways	From 1.9% + 20p (ShopWired Payments, Essentials)	UK-built; Royal Mail Click & Drop included; Essentials capped at £50,000 turnover a year
Wix	Core: £19/mo monthly, £16/mo annual	No platform commission reported	2.1% + 20p (Wix Payments)	Easiest editor; multi-currency needs Business (£25/mo annual)
Squarespace	Basic: £16/mo monthly, £12/mo annual	2% on Basic; 0% on physical products from Core (£17/mo annual)	Payment processor rates on top	Strong design templates; 14-day trial, no free plan
Square Online	Free: £0/mo	None	1.4% + 25p UK cards; 2.5% + 25p non-UK cards	Best if you already use Square in a shop or at markets
WooCommerce	Free plugin; you pay for hosting, theme and extensions	None	1.5% + 25p (WooPayments); +2% for non-UK cards	Most control; you or a developer handle hosting and updates

A few honest notes on the table:

• Wix and Squarespace UK prices come from a UK pricing review updated in 2026, because both companies show prices by location and we could not load the UK version of their own pages. Confirm the price at checkout.
• EKM, a long-standing UK platform, is worth a look too, but we could not access its current pricing page, so it isn't in the table. Check EKM directly.
• Monthly billing costs more on almost every platform. Annual billing saves money but locks you in for a year.

What the cheapest ecommerce platform in the UK really costs per year

The monthly fee is rarely the biggest cost. Card fees on every order usually are. Here is a simple worked example: a shop taking £2,000 a month in 50 orders (average £40), using each platform's own payments and annual billing.

Platform	Plan per year	Card fees per year	Total per year
Square Online (Free)	£0	1.4% + 25p → about £486	about £486
Wix (Core)	£192	2.1% + 20p → about £624	about £816
Shopify (Basic)	£228	2% + 25p → about £630	about £858
ShopWired (Essentials)	about £378	1.9% + 20p → about £576	about £954

This leaves out apps, themes, a domain, and VAT on subscriptions, which can add up quickly. It also shows why the "cheapest" plan depends on your volume: the higher your sales, the more the card rate matters compared with the monthly fee.

UK-specific things to check before you choose

Most platform reviews are written for the US. These are the points that matter for a UK shop.

VAT

You must register for VAT once your taxable turnover passes £90,000 in a rolling 12 months, or if you expect to pass it in the next 30 days (GOV.UK). Before that point, check that your platform can:

• show prices including VAT (UK shoppers expect it);
• handle zero-rated and reduced-rate products if you sell them;
• produce VAT invoices and export sales to your accounting software (Xero, QuickBooks, Sage).

ShopWired, for example, lists Xero, Sage, QuickBooks, KashFlow and Clear Books connections, included on Advanced and above and a £5/month add-on on Essentials (ShopWired pricing). With the UK moving towards mandatory e-invoicing, clean data matters more each year; see what the 2029 e-invoicing mandate means.

Shipping: Royal Mail, Evri, DPD

Ask how labels are printed. Some platforms connect natively to Royal Mail Click & Drop (ShopWired includes it on its listed plans); others rely on apps or a separate shipping service. If you post dozens of parcels a day, a smooth label workflow saves more time than any design feature.

UK payment methods

Cards, Apple Pay and Google Pay are standard. Also check PayPal, Klarna or Clearpay (buy now, pay later) if your customers expect them, and whether using a gateway other than the platform's own adds a fee (on Shopify Basic it adds 2%).

Selling abroad

If you ship to the EU or further, check multi-currency (on Wix it needs the Business plan) and how the platform handles international card surcharges: Square charges 2.5% + 25p on non-UK cards, and WooPayments adds 2% (Square, WooCommerce).

Support in UK hours

Support varies from round-the-clock chat to email only, and phone support is often limited to higher plans. Check what your plan includes before you sign up: ShopWired, for instance, lists unlimited and priority support on all its standard plans (ShopWired pricing).

Shopify vs ShopWired vs WooCommerce: which suits a UK small shop?

These are the three most common shortlists for a growing UK shop.

• Shopify is the safest default if you want to grow: a huge app store and a well-tested checkout. The downsides are app costs and the 2% third-party gateway fee on Basic. If you're weighing other options, our Shopify alternatives guide compares them in depth.
• ShopWired is built for UK sellers: Royal Mail Click & Drop, many UK gateways, trade accounts and accounting links come with the plans rather than as apps (on Essentials, trade accounts and accounting links are paid add-ons). The trade-off is a smaller ecosystem and turnover caps per plan (£50,000, £200,000 and £500,000 a year).
• WooCommerce costs least in licence fees and gives you full ownership, because it runs on WordPress on your own hosting. You pay for that with responsibility: updates, security, backups and speed are your job or a developer's.

Signs a ready-made platform isn't the right fit

Platforms work well for standard shops. They get expensive or awkward when:

• you're paying for five or more apps to make the store do what you need;
• your products need custom options or pricing (made to measure, bundles, quotes, trade price lists per customer);
• stock has to sync with a shop, warehouse or another system that has no ready app;
• you need your own customer accounts or portal, for example reorders, documents or approvals for trade buyers;
• you've hit turnover caps or plan jumps that cost more than the features are worth to you.

Having your store built and run for you

There is a third route between "do it yourself on a platform" and "hire an agency for a big one-off project": a store designed, built, hosted and maintained for you on a monthly subscription. That's what Buildly online stores are.

How it works: you send a free brief, get a written scope and price, and approve each stage: scope, wireframes, design, build and launch. On technology, we use whatever your project needs: custom code in Go, Node.js, Python, or PHP, or a platform such as WordPress, Drupal, WooCommerce, or Magento. We recommend the stack in your written scope, and you can ask for one you prefer.

Which plan fits (see all plans):

• Essential fits a website with a buy button for a few products: $35/month launch price (regular $60), $100 setup fee, the initial build at no extra charge, 2 change requests a year, and you own the source code and database after 12 months.
• Growth fits a small online shop with cart and checkout, from the price on our pricing page, with a $100 setup fee and 1 change request a month.
• Business fits an online store with accounts, stock and shipping, also from the price on the pricing page.

Standard integrations, such as a payment gateway or shipping service, are a one-time $20 each. Prices are in US dollars. After the plan's commitment, the contract is month to month.

How to choose, step by step

1. Write down your shop type: few products, catalogue with variants, trade, or something unusual.
2. Estimate monthly sales and order count, then work out yearly cost (plan + card fees + apps) for two or three platforms.
3. Check the UK essentials: VAT display and invoices, your courier, UK payment methods, accounting link.
4. Use the free trial to add five real products and go through checkout on your phone.
5. Check you can leave: export products, customers and orders as CSV before you commit.
6. If the list of apps and workarounds keeps growing, send a brief and compare a store built around how you sell.
