Our Website Design Results, By the Numbers
01
Your website should be your hardest-working employee.
Most UK business websites look fine and do nothing. They sit quietly, rank poorly, and lose visitors before a single enquiry comes through. That’s not a design problem — it’s a strategy problem.
At ClientGrowthWorks, we build websites the way a commercial director would: every page is structured around one goal — turning visitors into enquiries, bookings and sales. Design, copy and technical build all work towards that single outcome.
Frequently Asked Questions
What is ecommerce website development?
eCommerce website development is the process of designing, building, and launching an online shop where customers can browse products, add items to a basket, and complete purchases securely.
It covers everything from the visual design and user experience through to payment gateway integration, stock management, and ongoing technical maintenance.
How long does it take to build an ecommerce website?
Timelines vary depending on the size and complexity of your store. As a general guide:
- Small store (up to 50 products): 4–6 weeks
- Medium store (50–500 products): 6–10 weeks
- Large or bespoke store (500+ products): 10–16 weeks or more
Factors such as custom functionality, third-party integrations, and the speed of client feedback can affect the timeline.
Will my ecommerce store work on mobile phones and tablets?
Absolutely. Every ecommerce store we build is fully responsive and tested across all major devices and screen sizes — from iPhones and Android handsets to iPads and desktop monitors.
With over 70% of UK shoppers browsing and buying on mobile, a seamless mobile experience is not optional — it is essential. We build mobile-first as standard, not as an afterthought.
Can I manage my own products and content after launch?
Yes — complete independence is one of our core goals. After launch, you will be able to:
- Add, edit, and remove products
- Update pricing and stock levels
- Create discount codes and promotional offers
- Manage orders and process refunds
- Update page content and blog posts
We provide training as part of every project handover, and our UK-based support team is always on hand if you need assistance.
What information do I need to provide before development starts?
To get started efficiently, it is helpful to have the following ready:
- Your product catalogue (names, descriptions, images, prices, and variants)
- Your brand guidelines or logo files
- Preferred payment methods (e.g. Stripe, PayPal, Klarna)
- Any existing website login details if we are migrating your store
- Examples of websites you admire for style and functionality reference
Do not worry if you do not have everything ready — we will guide you through each stage.
Do I need to display VAT on my UK ecommerce store?
If your business is VAT-registered, you are legally required to display VAT-inclusive prices on your online shop when selling to UK consumers. For B2B stores, prices are typically shown exclusive of VAT with a note confirming it will be added at checkout.
We build VAT-compliant price displays into every UK store as standard and can configure your checkout to handle both B2C and B2B pricing structures where needed.
Is my ecommerce store GDPR compliant?
Data protection compliance is built into our ecommerce builds from the outset. Every store we launch includes:
- A cookie consent banner and management system
- A privacy policy template tailored for UK ecommerce
- GDPR-compliant contact and checkout forms
- Secure data handling and encrypted transmission (SSL)
We strongly recommend having your legal documentation reviewed by a qualified solicitor, as GDPR compliance extends beyond the website itself to your wider data handling practices.
