How to Become an Interior Designer in the UK
Interior designers plan the inside of homes, offices, hotels, shops and restaurants. You meet clients, measure spaces, draw layouts, choose materials, lighting, furniture and finishes, prepare mood boards and drawings, manage budgets and coordinate contractors so the finished room matches the design.
The title is not protected, so there is no compulsory route. Most interior designers study a degree or diploma in interior design, build a portfolio, then start as a junior or assistant designer in a studio. Others move across from architecture, retail design or home staging.

What a Interior Designer does
Design residential or commercial interiors - layout, materials, lighting, furniture and finish.
How to become an interior designer in the UK
Common routes are a degree in interior design or interior architecture, a Level 3 or Level 4 diploma in interior design from a college or private school, or a design apprenticeship with a studio. Employers expect skills in AutoCAD or SketchUp, hand sketching and mood boards, and knowledge of materials, lighting and relevant Building Regulations. The British Institute of Interior Design (BIID) is the main professional body, and its Registered Interior Designer status requires qualifications and professional experience. Self-employed designers also need professional indemnity insurance.
- Learn the basics of space planning, scale drawing and colour theory, and redesign rooms in your own home or a friend's to start a portfolio.
- Choose a degree, college diploma or accredited short course in interior design, and check that it teaches CAD and technical drawing.
- Learn AutoCAD or SketchUp and a rendering tool so you can produce floor plans, elevations and 3D visuals clients can understand.
- Build supplier knowledge by visiting showrooms and trade fairs and learning what fabrics, flooring and lighting cost and how long they take.
- Apply for junior designer or design assistant roles at residential, hospitality or commercial interior design studios.
- Work towards BIID membership and arrange professional indemnity insurance if you plan to take on your own clients.
| Route | How long | Cost | Best for |
|---|---|---|---|
| Interior design degree | 3 years | Tuition fee loan | School leavers wanting studio jobs |
| Level 3 or 4 interior design diploma | 1-2 years | Varies by provider | Career changers studying part-time |
| Assistant in a design studio | 2-4 years | Paid while you learn | People with a portfolio and drive |
How long it takes
Expect two to four years to train and build a portfolio strong enough for a junior design role. Running your own projects independently usually takes a few more years of studio experience.
