What our UI/UX design covers
Good design is not decoration. It is how quickly a visitor understands what you offer and what to do next.
User research
Interviews, analytics and recordings that show how people use your site today.
Customer journeys
Maps of the steps people take from first visit to enquiry or purchase.
Wireframes
Simple layouts that settle structure and content before visual design starts.
Clickable prototypes
Prototypes you can click through and test with real users before anything is built.
Interface design
Polished screens with a consistent style, ready for developers.
Accessibility
Readable text, strong contrast and layouts that work with keyboards and screen readers.
Our UI/UX design process
- Understand: we learn your goals, users and what is not working today.
- Research: we review analytics and talk to users where possible.
- Structure: we map journeys and create wireframes.
- Prototype and test: we build a clickable prototype and test it with real people.
- Design and hand over: we finish the interface and hand it to your developers or ours.
How pricing works
Pricing depends on the number of screens, how much research and testing is included and whether we also build the design. A redesign of a few key website pages is a smaller project than a full web app.
Every quote is written after a free consultation and we do not lock clients into long-term contracts.
Who this is for
Businesses whose website gets visits but few enquiries and teams building a web app or customer portal.
Who this is not for
Projects that need a finished website within days. Research and testing take time and skipping them defeats the purpose.

Frequently asked questions
What is the difference between UI and UX?
UX (user experience) is how easy and pleasant it is to get something done. UI (user interface) is what the screens look like. Good UX decides the structure; good UI makes it clear and on brand.
Do you build the design too?
Yes. Our developers can build the website or web app or we can hand finished designs to your team.
Do I need user research?
It is the fastest way to find out why people leave. Even a few interviews or session recordings usually reveal problems that nobody inside the business notices.
Will the design work on phones?
Yes. We design for phones first, then larger screens.
Do I have to sign a long-term contract?
No. We do not lock clients into long-term contracts.
