Certificate in Interior Design - QLS Level 3

The Certificate in Interior Design QLS Level 3 is the shorter of the two principal paid programmes. Its course record lists online, self-paced study and 200 recommended study hours.

The published syllabus introduces areas such as design principles, colour and lighting, space planning, materials and finishes, design presentation, client interaction and project-related skills. This route may suit learners who want a structured foundation without the longer commitment of the advanced diploma.

Advanced Diploma in Interior Design - QLS Level 5

The Advanced Diploma in Interior Design QLS Level 5 is the more extensive paid option and lists 450 hours of self-paced online study.

Its published learning areas include advanced design principles, space planning, colour theory, materials, furniture and lighting, interior decoration, project planning, client communication and portfolio development. Consider this route if you want greater subject depth and can commit to the additional study time.

Interior Design Short Courses

Shorter courses in this category provide focused introductions to particular aspects of interior design. These courses differ from the Level 3 certificate and Level 5 advanced diploma in their duration, scope and certification arrangements.

If your priority is to begin without a study fee, use the dedicated free interior design course hub to compare the available subjects. For these free short courses, certification is optional and paid separately. Learners may choose a CPD Accredited Certificate issued by the CPD Standards Office or a QLS Endorsed Certificate issued by the Quality Licence Scheme.

QLS certificate fees vary by course level and certificate format, while the CPD Standards Office certificate has its own price. Delivery choices may also affect the total cost. Review the current certificate fees and ordering information before purchasing.

Which Interior Design Course Should You Choose?

• Choose by depth: select a short course for a focused introduction, Level 3 for structured certificate-level study or Level 5 for broader coverage.
• Compare study hours: consider the time you can realistically commit before enrolling.
• Review the syllabus: check the exact modules and topics on the individual course page.
• Check certification: confirm the precise award or certificate and whether any additional fee applies.
• Consider your purpose: choose a course that matches your learning goals rather than relying on the title alone.

What Can You Expect to Study?

Subject coverage varies by programme, but available courses may explore:

• Balance, proportion, harmony and functionality
• Colour, texture, lighting, materials and finishes
• Space planning, furniture arrangement and room layout
• Interior decoration and styling
• Client communication and design presentation
• Project planning and portfolio development

The individual course page is the final reference for the exact syllabus and learning outcomes of the selected programme.

Flexible Online Study

The programmes are delivered online and presented as self-paced, allowing learners to organise study around work, family and other commitments. Tutor support, assessment and study-material arrangements can differ between courses, so review the selected course record carefully before enrolling.

Understanding Course Status

The Level 3 certificate and Level 5 advanced diploma have programme-specific fees and certification arrangements, which should be confirmed on their individual course pages. A QLS-endorsed course or certificate is not the same as an Ofqual-regulated qualification or a professional licence. If you need a particular qualification for employment, professional membership or further study, confirm the recipient organisation's requirements before enrolling.
