Ecommerce Website Redesign for UK Stores That Already Sell

An ecommerce website redesign rebuilds how your online shop looks and works while keeping the platform, the products, the customers and the order history. It usually covers the theme, navigation, collection and product pages, search and filters, the basket and the mobile layout. A replatform is different: it moves the whole store to new software.

Look at evidence first. If phone visitors leave far more often than desktop visitors, if staff avoid editing the homepage because the theme breaks, if your filters cannot handle the catalogue, or if the store still looks like it did five years ago while rivals moved on, a redesign is likely. If the platform itself blocks you, read the replatform section on this page.

You keep everything that already earns: the domain, the URLs that rank, the product data, the reviews and the customer accounts. Then you rebuild the templates around them. On Shopify that means a new or heavily reworked theme published over the old one. Customers keep logging in, orders keep flowing, and the old theme stays saved in case you need it.

Redesign if the platform still does what the business needs and the problem is the shop front. Move platform if you are paying developers to work around missing features every month, if the platform cannot handle your trade pricing or catalogue, or if it is near the end of support. A short review of your store usually settles the question in one call.

Yes. Shopify lets you build and preview a new theme while the current one stays live. We build the redesign as an unpublished theme in your own store, using your real products, and you review it on your phone before anything changes. Launch is a theme switch, plus the redirects for any URLs that changed. Shoppers see no downtime.

There is no fixed cycle. Redesign when the evidence says so: phone conversion well below desktop in GA4, Core Web Vitals failing in PageSpeed Insights, or staff unable to edit pages without a developer. A store that passes all three can wait and spend the budget on photography and copy.

Yes. A WooCommerce redesign is a new or reworked WordPress theme built on a staging copy of the site, so the live shop keeps trading. Products, customers and orders stay in the same database. Launch swaps the theme, and any URL that changes gets one permanent redirect. Move platform only if WooCommerce itself blocks how you sell.

AI tools can draft layouts, write first-pass product copy and suggest section orders quickly. They cannot decide which URLs to keep, check that every redirect fires once, or test a basket on a real phone. We use AI for drafts and people for the redirect map, the data and the launch checks.

It can, if URLs change without redirects or if pages that rank lose their content. Google says permanent redirects pass ranking signals without loss, so the risk sits in the mapping, not the redirect itself. We export every URL that gets traffic or links before design starts, map each one to its new home, and check them again after launch.

Five steps. List every URL that gets clicks, impressions or backlinks from Search Console and a crawl. Keep URLs the same where you can. Send every changed URL to its closest new page with one permanent redirect, never a chain. Keep the text and headings that ranking pages rely on. Then watch Search Console coverage and clicks daily for the first few weeks.

Shopify only follows a URL redirect when the old address returns a 404. Its own help pages say a redirect from a URL that still loads a valid page will not fire. So if an old collection or page is still published, the redirect is ignored. We unpublish or delete the old page first, then test every redirect in the map one by one.

It can. AI assistants and AI Overviews read your pages the way a search crawler does, so clear product data, collection pages that answer real buying questions, structured data and fast pages all help. A redesign is a good moment to add delivery, returns and sizing answers in plain text. We cover this alongside classic SEO in every store redesign.

Before design: export URLs with clicks and backlinks from Search Console and a Screaming Frog crawl, note the GA4 conversion rate by device, and run PageSpeed Insights on the top templates. Before launch: test every redirect, check each page has one H1 and its old title, and submit the new sitemap. After launch: watch 404s and clicks for a fortnight.

Check four things in the first fortnight. Pages that return 404 errors, which usually means a missing redirect. Redirect chains, where one URL hops through two others. Clicks on your top twenty pages compared with the same days before launch. And whether the new sitemap was read. A dip of a few days is normal while Google recrawls; a slide that keeps going is not.

Market figures vary with the size of the job. Whito, a UK price guide updated in October 2026, puts ecommerce websites at £5,000 to £20,000 or more. SpotDev, a UK HubSpot developer, puts UK redesigns at £10,000 to £80,000, with most B2B projects at £15,000 to £60,000. These are market ranges, not our prices. FactoryJet quotes a fixed price in writing after a short scoping call.

Whito found that copywriting, photography and SEO add 30 to 50% on top of a quoted price when nobody budgets for them. On a store, add product photo reshoots, app subscriptions that the new theme needs, redirect mapping and a fortnight of checks after launch. Ask for a quote that lists every one of these lines, even where the answer is that you supply it.

A custom-theme redesign on Shopify or WooCommerce usually takes 3 to 5 weeks. Stores with subscriptions, trade pricing or a migration take 5 to 8 weeks. A headless or custom build takes 8 to 14 weeks. The things that stretch a timeline are late product photos, late copy and features added after the scope was signed, so we agree those up front.

Yes, and for a trading store it is often the safer route. A common order is product and collection templates first, because that is where most revenue sits, then the homepage and navigation, then content pages and the blog. You can stop after any phase and still own a working store.

Sometimes. If the store converts well, loads fast and only looks dated, new colours, type, photography and a tidier homepage can be enough. If shoppers struggle with filters, product pages, the basket or the mobile layout, a refresh only paints over the problem. We will tell you which one you need before you spend money on either.

Yes. We build an unpublished preview theme on your own products, so live customers never see it. You tap through a product page, the basket and checkout on your own phone and send us notes.

Ask four things. Will they show a working draft on your own products before you sign? Who builds and tests the redirect map? Is the price fixed per phase, in writing? Do you own the theme and code from day one? A redesign agency that cannot answer all four clearly is pricing the design and leaving the risk with you.

Shopify and Shopify Plus, WooCommerce, BigCommerce and Adobe Commerce (Magento), plus headless stores built on Next.js. If the review shows your platform is the real problem, we plan a migration instead, and the redesign happens on the new platform as part of the same project.

You do, from day one. The theme sits in your own store and the code in a repository in your name. Apps, hosting and any AI tools can run in your own accounts at cost, with no markup.

Defects are fixed inside the build price for a cover period we agree before work starts. After that, support is optional: each change is quoted and approved before we do it, and there is no monthly minimum. You can book a one-off check before peak season and nothing else.
