How Long Is the NHS Speech and Language Therapy Waiting List? (2026)

Speech and language therapy (SLT) is often the first support a child needs, and the wait for it can feel agonising when communication is the very thing your child is struggling with. NHS waits vary widely by area, but the national picture gives you a realistic sense of what to expect.

How long is the NHS SLT waiting list?

The national average sits at around 46 weeks — close to 11 months — from referral to a first appointment (data updated April 2026). The realistic range is 6 to 18 months: some trusts see children within six months, while others exceed a year. Pandemic-era backlogs have not been fully cleared, and referral numbers continue to rise. You can compare SLT with other services on our NHS waiting times estimator.

Why do SLT waits vary so much?

Children’s SLT is commissioned and delivered locally, so capacity differs from one area to the next. The Royal College of Speech and Language Therapists has published a toolkit to help services bring waits down, which tells you how widely they vary. For more on this, see why NHS waiting times vary by area.

What can I do while I wait?

Ask your child’s school or nursery what communication support they can offer now — they do not need to wait for a diagnosis. Some families choose a private SLT assessment to get started sooner; our cost calculator shows realistic price ranges and our private speech therapy guide explains what is involved. You can find a verified SLT near you, or read how to get speech therapy faster.
