Interior design is one of the UK’s most appealing creative careers — combining artistic vision with practical problem-solving and technical expertise. With continued growth in residential renovation, property development and commercial design, more people are asking: how do I become an interior designer in the UK?
Whether you’re starting from scratch, changing careers, or looking to formalise your creative skills, this guide will walk you through everything you need to know about becoming an interior designer in the UK.
What Does an Interior Designer Do?
Before exploring how to become an interior designer, it’s important to understand what the role involves.
Interior designers do much more than style spaces — they design environments that improve quality of life for the intended occupants, while aligning with business objectives and brand values. Their work typically includes:
- Preparing site surveys and site inspections
- Project research and concept creation
- Space planning and layout design
- Selecting materials, finishes and furnishings
- Producing technical drawings, 3D visualisations, and specifications
- Managing client relations, budgets, and project timelines
In the UK, interior designers work across a wide range of sectors including private residences, commercial offices, retail environments and hospitality spaces.
“Interior design sits at the intersection of creativity and function. It’s about creating spaces that improve people's day to day lives, making interior environments pleasureable, effective, and appealing for the people using them.”
— Tom Nancollis, Interior Design Tutor
Step 1: Study Interior Design in the UK
One of the most common questions is whether you need qualifications to become an interior designer in the UK.
The profession is not legally regulated, which means you don’t need a licence to practise. However, most successful designers complete a recognised interior design course in the UK or online to build professional skills and credibility.
There are several study routes available:
Interior Design Short Courses
Ideal for beginners who want to explore interior design before committing to a full qualification.
Interior Design Diplomas (Most Popular)
A diploma is the most common route for adult learners and career changers. These courses are practical, flexible and focused on job-ready skills.
Interior Design Degrees
Some learners pursue a degree, particularly if they want to work in large design studios or architectural practices.
For many students, a flexible online interior design diploma in the UK provides the ideal balance between learning and existing commitments.
Step 2: Learn the Core Interior Design Skills
To succeed as an interior designer in the UK, you need a combination of creative, technical and professional skills.
A high-quality interior design course should cover:

- Technical drawing including floor plans, elevations, and sections

- Client communication and presentation skills
These skills are essential for working with clients, contractors and suppliers in a professional setting.
“A professional interior designer must be able to communicate ideas persuasively, with clarity and purpose. That’s when clients buy into design ideas and concepts become reality.”
— Tom Nancollis, Interior Design Tutor
Step 3: Build a Professional Interior Design Portfolio
