What Does a UX/UI Designer Actually Do? A Plain-English Guide
Updated on July 03, 2026 5 minutes read
Most people have strong opinions about apps they hate — buttons they can't find, checkout flows that lose their patience, screens that feel cluttered for no good reason. A UX/UI designer is the person responsible for making sure none of that happens.
The job title gets thrown around a lot, and the two letters — UX and UI — are often bundled together as though they mean the same thing. They don't, exactly. Understanding the difference is the first step to understanding whether this career might suit you.
UX and UI: the same role, or two different ones?
UX stands for user experience. UI stands for user interface. In practice, many companies — especially smaller ones and start-ups — hire one person to cover both. Larger organisations, particularly in London's tech scene or at established product companies in Manchester or Edinburgh, sometimes split the roles.
UX work is about the logic of a product: how it flows, whether it solves a real problem, and whether users can actually accomplish what they came to do. UI work is about the visual layer: colour, typography, spacing, button states, and everything a user actually sees and touches.
A useful way to picture it: imagine a house. UX is the floor plan — where the rooms go, how you move between them, whether the kitchen is next to the dining room for a reason. UI is the interior design — the paint colours, the furniture, the light fittings. Both matter. Neither works well without the other.
What a UX/UI designer actually does day to day
The work varies enormously depending on the company, the stage of the product, and the team structure. But a fairly typical week might include:
- Running user interviews to understand how real people approach a problem
- Reviewing analytics to find where users drop off in a product flow
- Sketching rough wireframes on paper or in a tool like Figma
- Building interactive prototypes and sharing them for feedback
- Working closely with developers to make sure the final build matches the design intent
- Presenting design decisions to stakeholders and backing them up with evidence
The research side of the job surprises many people who come into UX/UI expecting to spend most of their time making things look polished. In reality, a strong design rationale — knowing why a button is placed there, not just that it looks right — is what separates junior designers from those who advance quickly.
Tools you'll likely use
Figma has become the industry standard for most design work in the UK, used across agencies, in-house product teams, and freelance projects alike. You'll also encounter tools like Miro for collaborative whiteboarding, Maze or Useberry for usability testing, and occasionally Adobe XD at legacy organisations.
That said, tools change. What employers are really hiring for is a design process: the ability to frame a problem, generate solutions, test them, and iterate. The specific software is secondary.
UX/UI vs. product design: what's the difference?
| Role | Focus | Common at |
|---|---|---|
| UX Designer | User research, flows, information architecture | Larger product teams, agencies |
| UI Designer | Visual design, component libraries, brand consistency | In-house teams, design studios |
| UX/UI Designer | End-to-end design from research to visual | Start-ups, SMEs, bootcamp graduates |
| Product Designer | Strategy, UX, and UI with business ownership | Scale-ups, tech companies |
Product designer is increasingly the job title used at companies like Monzo, Wise, and other UK-based fintech firms. It signals that the person is expected to think beyond aesthetics and take some ownership of product outcomes. Many UX/UI designers grow into product design roles over time.
What skills do you actually need to get started?
You don't need a degree in graphic design or a background in psychology — though both can help. What you do need is curiosity about how people behave, the patience to test assumptions rather than defend them, and a willingness to learn tools that are genuinely learnable.
Soft skills matter more here than in some other tech roles. Clear communication, the ability to give and receive critique, and comfort presenting your thinking to non-designers are all things hiring managers consistently cite. A well-structured portfolio that shows your process — not just the finished screens — will get you further than a CV full of credentials.
Entry-level UX/UI roles in the UK, including junior product designer and associate UX researcher positions, are realistic starting points for career changers. The field has welcomed people from backgrounds in teaching, psychology, marketing, and even healthcare, because understanding people is the core skill.
How to build the skills from scratch
A structured learning path helps — particularly one that includes feedback from working designers and hands-on project work. Reading articles and watching tutorials can take you some of the way, but the gap between knowing what a wireframe is and being able to defend your wireframe decisions in a job interview is where proper practice comes in.
If you want to see everything that goes into a professional UX/UI curriculum, browse the full range of tech courses at Code Labs Academy — including design, data, and development programmes. For those ready to commit, the UX/UI Design bootcamp at Code Labs Academy covers research methods, Figma, prototyping, and portfolio development in a structured format built around the UK job market.
Those who prefer flexibility can also explore the self-paced UX/UI Design programme, which lets you work through the material around existing commitments.
The honest reality of the job
UX/UI design is genuinely collaborative work. You'll spend time in meetings, justifying decisions, and sometimes watching your best ideas get changed by business constraints. That's not a reason to avoid the field — it's just worth knowing before you start.
What the job offers in return is real ownership over how people experience a product. When you get it right, people don't notice — they just complete their task without friction, without frustration, and without thinking about design at all. That invisible success is, for many designers, the most satisfying part of the work.
If you've ever looked at a confusing app and thought "I could fix this," that instinct is exactly where a UX/UI design career begins. The Code Labs Academy UX/UI Design bootcamp is a practical place to turn that instinct into a portfolio and a job title.
