Shopify website design
A custom Shopify theme that looks like your brand, not the theme store, and stays easy to run day to day.
Shopify website design for UK businesses
Shopify website design works best when the theme is built for your products rather than borrowed from the theme store. Off-the-shelf themes carry features you will never use, which slows pages down and makes editing confusing. We design and build custom themes on Online Store 2.0, so every section is one you actually need and your team can rearrange pages without calling a developer.
We start with how your customers shop. A brand with a handful of hero products needs a different store from a retailer with thousands of SKUs and deep filtering. Once the structure is agreed, we design the key templates, build them as reusable sections, connect the apps you rely on, and test the whole store on phones before launch.

What we build
- Custom themesDesigned from scratch on Shopify's Online Store 2.0.
- MigrationsFrom WooCommerce, Wix or Magento, redirects included.
- Apps & integrationsStock, reviews, subscriptions and accounting.
- SpeedLean themes that pass Core Web Vitals.
Custom Shopify website design on Online Store 2.0
Custom Shopify website design means the homepage, collections, product pages and basket are all designed for your range and your brand. We build them as flexible sections and blocks in the Shopify theme editor, so you can launch a new landing page, reorder a collection or add a seasonal banner yourself. The code stays lean, which helps pages pass Core Web Vitals and keeps the store quick on mobile data. Collections are structured around the terms people search, with written introductions and sensible filters, so they can rank in their own right.
- Product templates for different product types, not one layout for everything
- Metafields for specs, ingredients, sizing or care details
- Section library your team can use to build new pages
Shopify web development: apps, integrations and speed
Many slow Shopify stores are slow because of apps, each loading its own scripts on every page. Our Shopify web development work audits what is installed, removes what you don't need, and builds simple features into the theme instead of adding another app. Where an app is the right answer, such as reviews, subscriptions or stock syncing, we integrate it cleanly. We also connect Shopify to accounting, fulfilment and email marketing tools, such as Xero, your warehouse or courier software, and Klaviyo, so orders, stock and customer data stay in step without manual exports.
Choosing a Shopify web design agency, and when Shopify Plus fits
A good Shopify web design agency should tell you when you don't need more. Most growing UK brands run well on standard Shopify plans. Shopify Plus starts to make sense with higher order volumes, wholesale selling through Shopify's B2B features, or a need for more checkout customisation. We design for both, and the audit gives you a straight answer on which plan suits your business today. If you are already on Plus, we can redesign the store and its checkout without disrupting live trading.

Questions
How much does Shopify website design cost in the UK?
It depends on scope: a redesign of an existing store differs from a full build with migration and integrations. The free audit looks at your store and ends with a clear written quote. It also lists any app or Shopify plan costs separately, so you can see the full picture.
Do you build custom Shopify themes or adapt existing ones?
Custom themes. They are faster, easier to edit and don't break when an off-the-shelf theme updates.
Can I keep my existing Shopify store and apps?
Yes. We can redesign on top of your current store, keeping products, customers and the apps you rely on.
Is Shopify right for my business?
For most UK retailers selling physical products, yes. The audit tells you honestly if something else would suit you better.
Do you work on Shopify Plus?
Yes. We design and build Shopify Plus stores, including B2B wholesale setups and checkout customisation. We will also tell you if a standard plan would do the job, since Plus is a significant monthly commitment that only pays off at the right scale.
Can you move my store from WooCommerce to Shopify?
Yes. Products, customers and order history are migrated, and every old URL is redirected to its new home so search engines and bookmarks still find the right page. Customers are invited to set a new password, and we check orders, taxes and shipping rates before switching over.
