What does the interior design profession involve?

Many peopel think it’s simply about choosing some fabrics and some colours for a room and calling it a day.

But there is sooooo much more that goes into interior design to help create a space that is both functional and beautiful. Designers work on homes, offices, hotels and retail environments, considering elements like lighting, furniture, and acoustics to create a cohesive atmosphere.

Did you know that good design can enhance your quality of life, increase a property’s value and reflect your personal style, so it doesn’t look like someone else designed a room? Whether it’s a cosy living room or a sleek office, interior designers can significantly impact how people experience their surroundings.

 

Becoming an interior designer through education

If you’re wondering how to become an interior designer in the UK, you’re not alone. There are multiple ways in which you can enter this exciting field, whether you choose to pursue formal education or take a more unconventional route.

With an undergraduate degree

The most common route is to take a bachelor’s degree in interior design, interior architecture, or a closely related subject. These courses usually last three to four years and cover everything from design theory, colour and materials, to CAD software, spatial planning, and project management. Some popular courses may also include practical projects and placements to give you hands-on experience.

With a foundation course/diploma

If you don’t meet the entry requirements for a full degree, a foundation course or diploma in interior design can be a great starting point. These programmes focus on core skills like sketching, colour theory, and design principles, preparing you for a degree or directly for junior roles in the industry.

With a postgraduate degree

If you already have a degree in another subject, a master’s in interior design or interior architecture is an option. Postgraduate courses tend to be more focused and advanced, often with a mix of creative and technical training.

With vocational qualifications and professional courses

Shorter vocational courses, such as Level 3 or Level 4 diplomas in interior design, are offered by colleges and private institutions. These are practical, hands-on programmes that teach essential skills for working in the field and can sometimes be combined with apprenticeships.

How to become an interior designer without a degree

You don’t necessarily need a degree to become an interior designer. In fact, many successful interior designers have built their careers through apprenticeships, work placements and self-study. Interior design courses online and workshops can also provide valuable knowledge and skills.

If you want to success without a degree, then you should instead focus on building a strong portfolio, gaining practical experience and continuously improving your skills through courses and workshops. Practise, practise, practise!

How to become an interior designer with an architecture degree

If you already have a degree in architecture, you’re well-positioned to transition into interior design. Your background will give you a strong foundation in spatial concepts and technical skills, which can be easily adapted to interior design.

After your degree, you could do a university course (or an open university course) in interior design, or gain some experience by working for another interior designer until you feel confident enough to set up on your own.

 

What essential skills and qualifications does an interior designer need?

Being an interior designer requires a unique blend of creative and technical skills. Here are some of the key skills you’ll need to succeed:

• Creative vision
• Space planning and layout
• Strong understanding of colour theory
• Knowledge of materials, finishes, and textiles
• Attention to detail
• Technical drawing and design software skills
• Problem-solving ability
• Project management
• Budget management
• Communication and presentation skills
• Client relationship management
• Knowledge of building regulations and safety standards
• Time management and organisation
• Ability to adapt to different styles and briefs
• Ability to collaborate with trades, suppliers, and contractors.

You’ll also need to be proficient in design software like AutoCAD and SketchUp, and have a solid understanding of colour theory, textiles and spatial arrangements.

Can an interior designer become an architect?

The qualifications you have to become an interior designer generally won’t allow you to become an architect. Training in architecture can take many years and you’ll likely need a minimum of a degree. However, if it’s a path you want to pursue, it’s certainly worth looking into. Many interior designers make great architects because of their ability to visualise a space or building, and be creative.

 

Gaining experience as an interior designer

Everyone has to start somewhere, and a lack of formal experience doesn’t mean you can’t begin building a career in interior design. One of the simplest ways to get going is by taking on small projects for friends or family. These early jobs give you something just as important as confidence: real examples of your work.

Volunteering or offering your services on a pro bono basis can also be a smart move, particularly for charities or community projects. Not only does this help you develop practical skills, but it also allows you to start building a portfolio you can show to future clients. Over time, these early projects add up and give you proof of what you’re capable of when paid opportunities start to come your way.

Internships and work placements

Internships and work placements are another great way to gain hands-on experience. Working alongside established designers lets you see how projects run from start to finish, from client briefs to final installations. These roles can also help you develop industry-specific skills and, in many cases, act as a stepping stone into paid or full-time work.

Networking and professional associations

Networking plays a big role in the interior design industry. Joining professional organisations such as the British Institute of Interior Design (BIID) can open the door to valuable resources, support and industry connections. Attending events, workshops and seminars helps you meet other designers, learn from their experiences and stay up to date with current trends and best practices.

 

How to build an interior designer portfolio

A strong portfolio is essential for showcasing your skills and attracting clients or potential employers. Any potential client will want to see a portfolio so they can see your previous work and if they like your design and style.

So where on earth do you start when building a portfolio?

I’d suggest that you build an online and a physical portfolio. In most cases, the interior design work you do will probably be local, as it’s easier for you to contact suppliers and be there to help prepare the room. Therefore, any initial meetings will likely be in a person and a physical portfolio can be really useful. Bring it along to show your potential client what you can do.

An online portfolio is ideal too, should a potential client ask for you to send it via email, as a PDF.

What should the portfolio include?

Your portfolio is your calling card, and therefore it should showcase your best work and demonstrate your ability to handle various projects and design styles. You should include high-quality photos, detailed descriptions and any sketches or plans that highlight your process. You might even want to include real fabric samples.

Absolutely focus on quality over quantity. I’d recommend that you choose a variety of projects that showcase different skills, from residential to commercial spaces, making sure each project is professionally photographed and well-documented.

 

How do you find interior design clients?

Once you’ve built your skills and portfolio, the next step is putting yourself in front of the right people. Finding interior design clients is usually a mix of visibility, networking and being proactive rather than waiting for opportunities to land in your lap.

Use online job portals and design platforms

Online job portals can be a useful starting point, especially if you’re looking for junior roles, internships or contract work.

Keep your CV and portfolio up to date and tailor them to each role you apply for to highlight relevant skills and experience, using a CV template for no experience if needed. Design-focused platforms and creative job boards can also be worth keeping an eye on, as roles aren’t always advertised on mainstream sites.

Attend industry events and design shows

Industry events are one of the best ways to meet people face to face. Trade shows, workshops and interior design exhibitions give you the chance to connect with other designers, suppliers and potential clients. Even casual conversations can lead to referrals or future work, so it’s worth showing up regularly and getting comfortable talking about what you do.

Join professional associations and networking groups

Joining professional bodies such as the British Institute of Interior Design (BIID) can help you build credibility and expand your network. Local business networking groups can be just as valuable, particularly if you’re working freelance and want to connect with architects, builders or property developers who may need design support.

Reach out directly to interior design firms

If you’re looking for employment or freelance collaborations, don’t be afraid to contact interior design studios directly. A short, well-written email with a link to your portfolio can go a long way. Even if there isn’t an immediate opening, you’ll be on their radar for future projects or placements.

Decide whether to work for a firm or freelance

The way you find clients will often depend on whether you work for an interior design firm or freelance. Firms can provide a steady flow of projects and mentorship, while freelancing requires you to actively market yourself and build relationships. Think about your long-term goals, income needs and preferred working style when choosing which route to take.

 

How do you keep up with trends as an interior designer?

The world of interior design is always evolving, so staying on top of trends is key to keeping your work fresh and relevant. Here’s how designers typically stay ahead of the curve:

Follow industry publications and blogs
Magazines, online blogs, and design websites are a goldmine for inspiration and trend spotting. Regularly reading these sources can help you see what’s popular in colour palettes, materials, furniture, and layouts.

Attend trade shows and exhibitions
Events like design fairs, home shows, and furniture exhibitions give you a first-hand look at new products and innovations. These experiences also help you understand what clients may soon be asking for.

Engage with social media and online communities
Platforms like Instagram, Pinterest, TikTok, and LinkedIn are full of designers sharing fresh ideas. Following other professionals, brands, and influencers can give insight into emerging trends before they hit the mainstream.

Network with other designers and suppliers
Talking to colleagues and suppliers can provide practical insights into what’s working in real projects. Sometimes trends are spotted in the field before they’re written about in magazines or online.

Keep learning and experimenting
Finally, staying curious and trying out new styles, materials, and techniques in your own projects keeps your skills current. Trend awareness isn’t just about copying — it’s about knowing what works and how to adapt it creatively for your clients.

 

Certification and licences

While formal certification isn’t strictly necessary to work as an interior designer, earning credentials from professional organisations like the British Institute of Interior Design (BIID) can give your career a real boost. These certifications usually involve meeting specific educational and professional standards and, in some cases, passing exams, but the payoff is worth it: they signal to clients and employers that you have proven skills and expertise.

Accreditation from recognised institutions also shows that you adhere to industry standards, giving you a competitive edge in a crowded market. Beyond credibility, it can open doors to higher-profile projects, improve your job prospects, and even increase your earning potential.

 

Income and career prospects

 

Understanding the financial aspects and career growth opportunities in interior design can help you plan your career.
