How to Start an E-commerce Business in the UK: What the Two Shops We Run Taught Us

By Measured 5 September 2026

Opening an online shop takes a weekend. Getting anyone to buy from it takes the parts of the job the platform adverts leave out: product data, findability and trust.

The short answer

To start an e-commerce business in the UK: decide what you sell and to whom before touching software; choose the platform by team size and product complexity (Shopify for simplicity, WooCommerce for ownership and unusual products); register the business, understand VAT thresholds, distance-selling rules and returns law; get the product data right (titles, attributes, images, stock) because it is what search engines, shopping feeds and customers all read; set up Search Console, Merchant Centre and analytics before launch; and plan how people will find the shop, because a new store has no visitors by default. The two shops we run show the two ends: a 17,000-product retailer whose growth came from making the catalogue reachable, and a 1,000-line sweet shop whose sales came from a buying journey no template offered.

Before any software: what, to whom, and why you

Every platform advert promises a shop in minutes, which is true and beside the point. A shop is a decision about what to sell, to whom, at what margin, against whom. Answer those on paper first: who buys this, where do they look for it now, what do they pay, why would they buy from you rather than the marketplace that already ranks for it. If the answer to the last one is “price”, you will be competing with Amazon on price, and that is a decision too.

The sweet shop we built had a real answer: pick and mix by the kilo, filled to the gram, halal and vegan ranges, same-day dispatch, from a family shop in Rochdale. Its Search Console shows non-brand clicks for “halal liquorice allsorts” and “halal jelly babies” that a generic sweet retailer would never see. The answer to “why you” became the products, the pages and the searches.

Choosing the platform

The platform decision for a new UK shop
ChooseWhenWatch out for
ShopifySmall team, standard products, want the simplest possible operation and will pay monthlyPlan fee plus payment rates plus apps; locked checkout; you licence, not own
WooCommerce (WordPress)Want to own the shop, no platform fee, many products or variations, or a buying journey no template offersNeeds hosting and care; you or your host maintain it

  • Register the business (sole trader or limited company) and register for VAT when turnover approaches the threshold, or earlier if it suits you. Your accountant, not this page, is the authority.
  • Consumer Contracts Regulations: distance sales give consumers a 14-day cancellation right on most goods, and you must state it, along with delivery costs and timings, before they buy.
  • Consumer Rights Act: goods must be as described, of satisfactory quality and fit for purpose; your returns policy cannot remove those rights.
  • Pricing: the total price including VAT must be clear; delivery charges shown before checkout.
  • Privacy: a privacy notice, lawful basis for marketing emails (PECR), and a cookie banner that actually asks.
  • Reviews: since April 2025, fake or undisclosed incentivised reviews are a banned practice under the DMCC Act.

Product data: the part that decides whether you are found

This is the step every “start a shop” guide skips and the one that decided the largest result on this site. A product is only sellable online if a machine can understand it: a title in the words people type, the attributes (size, colour, material) in the fields the platform provides rather than in a paragraph, a unique description, sized images, a real stock level and a price. Search engines, Google Shopping and your own site search all read those fields.

Beds.ie had around 17,000 products and search engines were reaching a fraction of them. Fixing the structure and data so the pages were reachable and Merchant Centre would accept the products (16,281 of 17,233 approved) took organic clicks from 672 to 7,781 a month between April and August 2026. Nothing about the shop’s look changed. The data did.

Being found: a new shop has no visitors

  1. Set up Google Search Console and submit the sitemap before launch, so indexing starts on day one.
  2. Set up Google Merchant Centre and a product feed; free listings put your products in Google Shopping without adverts.
  3. Write category pages that answer the search (“halal sweets”, “pick and mix by the kilo”), not just list products.
  4. Put analytics and conversion tracking in place so you can see which products and searches produce orders.
  5. Expect the first months to be brand traffic and marketplaces. The Rochdale shop’s Search Console shows roughly nine in ten clicks from its own name in its first year; the non-brand share is what the growth work moves.

The two things that decide whether it sells

Trust and friction. Trust is a named business with an address, a phone number, real photos of real products, a returns policy that reads as fair, and reviews you can click through to. Friction is every field, every surprise delivery charge, every slow page between wanting the thing and owning it. The sweet shop’s pick-and-mix builder exists because the friction of choosing sweets by the kilo through a standard variant picker would have lost the sale; the gift-list platform we built exists because guests buying from a couple’s list is not a shop journey at all. Fit the checkout to how people actually buy, and measure where they leave.

Common questions

Questions people actually search for.

How do I start an ecommerce business in the UK?

Decide what you sell, to whom and why you before software; choose Shopify or WooCommerce by team size and product complexity; register the business and learn the VAT, distance-selling and returns rules; get product data right; set up Search Console, Merchant Centre and analytics before launch; and plan how people will find you.

How much does it cost to start an online shop?

Shopify: a monthly plan plus payment rates and apps. WooCommerce: hosting and care (from £50 a month with us) plus a build (from £500 with us, more for a large catalogue or a custom buying journey). Plus stock, photography, and the time to get product data right.

Shopify or WooCommerce for a new shop?

Shopify for a small team with standard products who want simplicity and accept a monthly fee and a locked checkout. WooCommerce to own the shop, avoid platform fees, handle many products or variations, or build a buying journey no template offers.

What legal requirements apply to selling online in the UK?

Business registration and VAT when due; the Consumer Contracts Regulations’ 14-day cancellation right and pre-sale information; the Consumer Rights Act on quality and returns; clear VAT-inclusive pricing; a privacy notice and PECR-compliant marketing; and no fake or undisclosed incentivised reviews under the DMCC Act.

How do I get customers to my new online shop?

Search Console and a sitemap from day one, Merchant Centre free listings, category pages that answer real searches, marketplaces alongside while your shop earns its place, and product data a machine can read. Expect early traffic to be your own name; the non-brand share is what grows.

Why is product data so important for ecommerce?

Because search engines, Google Shopping, filters and site search all read the same fields. A 17,000-product store went from 672 to 7,781 organic clicks a month mainly by making its product data reachable and acceptable to Merchant Centre. Nothing about the design changed.

Starting a shop and not sure where?

Tell me what you sell, roughly how many lines, and who buys it. You get a platform answer, the product-data fields that matter for your range, and the first three things to set up before launch.
