Developmental Language Disorder (DLD): Getting Help in the UK

Uses your browser’s own voice. Nothing is sent to us.

In short: Developmental language disorder (DLD) affects how children understand and use language. The Royal College of Speech and Language Therapists (RCSLT) says it affects 7.58% of children, is lifelong, and that the right support can make a difference. Speech and language therapists assess DLD and teach strategies to the child and the people around them. You can get help through the NHS or an independent speech and language therapist.

What DLD Is

The RCSLT says DLD is a type of speech, language and communication need that affects the way children understand and use language, for example producing or understanding complex sentences, or learning new words. 'Developmental language disorder' is the term used when the language disorder is not associated with a known condition such as autism, brain injury, Down's syndrome or sensorineural hearing loss. Older terms included 'specific language impairment'. Source: RCSLT: developmental language disorder.

How Speech and Language Therapy Helps

The RCSLT says an SLT may identify, assess and diagnose communication difficulties, deliver strategies and therapy programmes, support schools to use strategies in the classroom, help parents and teachers with communication techniques, and support parents after a diagnosis. After assessment, the SLT works with the child and family to set communication and personal goals, monitors progress, and gives extra support at transition points such as starting nursery or moving to secondary school. Because DLD is lifelong, people may use speech and language therapy at different times in their life.

Getting an Assessment

If you are worried about your child's understanding or talking, speak to your GP, health visitor, or your child's nursery or school. Our guide to speech and language delay in children explains how NHS speech and language therapy works and what is typical at each age. You can also see an independent speech and language therapist. Speech and language therapist is a protected title, so check the HCPC register before you book.

Whoever you choose, check their register and ask about fees, session length and how you will review progress together. See questions to ask a private allied health professional and how much therapy costs. On Therapist Circle, each practitioner's registration is checked when they join, and their profile shows the register and number so you can check it yourself.

Support Organisations

The RCSLT lists organisations including Afasic, which supports children and young people with language disorder and their families, and Speech and Language UK, a children's communication charity. See also our guides to selective mutism and which professional is right for my child.
