No. A GP cannot diagnose ADHD or autism in the UK; both need a specialist assessment, usually by a multidisciplinary NHS team. Your GP's job is to refer you, and in England you can use Right to Choose.
Why a GP can't make the diagnosis
A GP is a generalist. ADHD and autism are diagnosed against recognised criteria (ICD-11 or DSM-5) after a detailed developmental history, direct observation, and structured assessment tools, which sits outside what a GP appointment can cover. NICE guidance is clear that an autism diagnosis should come from a specialist team, not primary care.
The people who actually diagnose differ by condition:
- Autism: a multidisciplinary team that, for children, should include a paediatrician and/or child psychiatrist, a speech and language therapist, and a psychologist with autism training.
- ADHD: a specialist such as a psychiatrist, paediatrician, or a specialist ADHD nurse, who can also start and review any medication.
What your GP does instead
Your GP is the gateway, not the assessor. They listen to your concerns, rule out other explanations, and refer you on to the right local service (CAMHS, a community paediatric team, or an adult neurodevelopmental service). It helps to bring concrete examples, anything the school or nursery has written down, and to ask the GP to put the referral in writing so you have a dated record.
A GP also cannot privately diagnose either condition, and they will not normally accept symptoms reported only by you as a basis for a prescription without a specialist diagnosis behind it.
Why this matters when waits are long
Because diagnosis is specialist-only, the referral is the thing that starts the clock, and NHS neurodevelopmental waits can run from many months to several years depending on your area. In England you have a legal right to choose your provider for an NHS-funded assessment (Right to Choose), which can mean a shorter wait with a different NHS or independent provider at no cost to you. A private assessment is also an option, though you may need extra steps for the NHS to recognise it, especially for ADHD medication.
