What is the difference between interior design and interior decoration

Professional practice distinguishes spatial planning and technical coordination from arranging furniture, colour and decorative elements, with overlap between roles.
Interior design includes planning, function and technical coordination within the practitioner’s competence; decoration focuses on visual composition, furniture and finishes. Roles overlap and practice requirements vary by jurisdiction. A title alone does not establish qualification for every task.
Define the project scope, required qualifications and responsibilities before appointment. An interest in appearance does not authorise structural or electrical work outside competence, and unidentified studies do not establish clinical recovery from decoration.
