Speech and Language Therapy (SLT) and Occupational Therapy (OT) are two of the most used therapies in UK autism services. While both play an important role, they focus on different areas of development and support. According to NICE and NHS guidance, SLT primarily supports communication and social interaction, while OT focuses on sensory processing, daily living skills and participation in everyday activities.

SLT and OT often work together within multidisciplinary autism pathways, rather than functioning as separate or competing interventions.

What Speech and Language Therapy supports

SLT focuses on understanding and using language, social communication, and alternative communication systems. The National Autistic Society notes that autistic people may experience differences in language, non-verbal communication and social understanding, and SLTs help identify strengths and provide practical strategies.

NICE guidance for under-19s highlights the need for interventions that promote communication and adaptive skills. Detailed recommendations in NICE guidance emphasise treating communication difficulties through evidence-based SLT approaches while advising against unsupported alternatives like neurofeedback or auditory integration training.

Real-world NHS services show the range of SLT roles. Hertfordshire Community NHS Trust focuses on speech, language and participation, while Great Ormond Street Hospital provides specialist assessment for complex neurodevelopmental needs.

What Occupational Therapy supports

OT helps autistic people develop practical, everyday skills across home, school, work, and community settings. According to, NHS West London – Children’s OT Service OT support sensory processing, self-care, play and school participation using universal, targeted and specialist input.

NICE guidance for adults recommends structured, predictable programmes to build daily living and community skills in CG142 roles often delivered by occupational therapists within multidisciplinary teams. For children, CG170 recognises that OT may be essential for sensory and functional issues, even if high-quality RCT evidence is still emerging.

Evidence and real-world use

The 2021 NICE surveillance review concluded that new evidence was unlikely to change current recommendations, meaning SLT and OT remain core components of autism support across ages. SLT has stronger structured evidence for communication outcomes, while OT has emerged, though still limited evidence for sensory and functional improvements. In practice, both are widely used because they meet distinct and essential needs.

Takeaway

SLT and OT address different but equally important areas of development for autistic people. SLT focuses on communication and social interaction, while OT supports sensory processing, daily living, and meaningful participation. NICE and NHS guidance position both therapies as core parts of multidisciplinary autism care, with each contributing unique strengths that help autistic people develop skills, confidence and independence.
