It is understandable to feel dismissed, especially after building up to the appointment. A GP deciding not to refer you does not determine whether you or your child are autistic. There are clear, practical steps you can take, and this article walks through each one in detail.
Key Takeaways
- Ask for the reason and what evidence or next step would change the decision
- Bring concrete examples of lifelong or current impact to any appointment
- A private route may be an option; verify process, credentials, and costs before booking
- Urgent mental health needs need urgent support, not an assessment-waiting strategy
- A screening consultation is not a diagnosis; it is a first conversation
What can you do if a GP will not refer you?
Ask for the specific reason. Find out what evidence would help them reconsider. Ask whether a review appointment or a different clinician at the same practice is possible. Ask which local autism diagnostic service would receive a referral, who is allowed to refer and whether that service accepts self-referrals. Requirements vary between services.
If a self-funded private assessment is right and affordable for your circumstances, many providers accept direct bookings without a GP referral. Check the provider’s process before booking. You can explore Autism Detect’s adult autism assessment or children’s autism assessment pathway, depending on who needs the assessment.
First: Take a Breath and Get Clear on What Happened
Before your next step, note the date, who you spoke to, and the exact reason given. Possible reasons for a referral not being made include:
- Missing or insufficient information at the appointment
- Another health concern being checked first
- Local pathway criteria or capacity issues
- Or a recommendation to monitor and return
None of these permanently closes the door. Ask what would change the decision and whether a written explanation is available.
Also clarify whether the GP decided not to refer, or whether a referral was sent and the receiving service did not accept it. These are different situations. If a service rejected the referral, ask for its reason and what information or alternative pathway it recommends.
What to Say at the Next Appointment
For adults, focus on lifelong patterns: childhood experiences, how daily life, work, and relationships have been affected, sensory sensitivities, and any periods of significant exhaustion or burnout. Be specific. “I have always found noisy environments very difficult to manage” is more useful than “I struggle with noise.”
For parents speaking about a child, describe what you observe across settings: home, school, and social situations. Bring any school or nursery observations if you have them.
If you want to explore whether your concerns are consistent with autism before going back to the GP, Autism Detect’s initial autism screening consultation is a 15-minute clinician-led session that can help you understand whether a full assessment is likely to be worthwhile. It is not a diagnostic assessment; it is a starting conversation.
A private screening consultation is not a prerequisite for asking your GP about an NHS referral
If the Concern Is About Your Child
If the concern is about your child, ask which local service handles autism referrals and whether the GP, school or health visitor can refer. Bring school or nursery observations if available, alongside specific examples from home and your child’s developmental history. Ask what information the receiving service needs rather than assuming that school evidence or a particular screening result is mandatory.
Autism Detect’s children’s autism assessment pathway is available if you decide to explore a private route for your child.
Ask About Review, Another Opinion, and the Local Pathway
Ask the GP what the local autism assessment pathway looks like, including whether self-referral to NHS services is possible in your area. Ask whether a review appointment in a few weeks is appropriate, or whether a second GP at the practice could consider the referral. If the conversation has broken down, ask the practice manager about the NHS complaints and advocacy process, this is factual information you are entitled to. ⁵
Could Right to Choose Help in England?
If you are in England, ask your GP whether Right to Choose applies to your situation. This may allow referral to another NHS-funded provider, including an independent organisation, rather than the usual local service.
It still requires a GP referral for the pathway described here. It is not a self-referral workaround if the GP does not consider an assessment clinically appropriate. If a referral is agreed, check the receiving provider’s current criteria and availability. Do not assume this England-specific route is available in the same form elsewhere in the UK.
Private Assessment Is Another Route, Not a Test You Have Failed
Choosing to explore a private assessment does not mean the NHS failed you or that you have given up. It means you have decided to use a different route. Before booking, check: who will assess you, their professional registrations, whether the assessment covers developmental history, what the written report includes, and the total cost.
You can explore Autism Detect’s private adult autism assessment pathway or its in-person autism assessment option. Autism Detect advertises self-referral without a GP letter for its private in-person assessments. Choosing face-to-face appointments does not itself create a GP-referral requirement; ask which parts of the process take place in person and which are completed remotely.
What Happens After an Assessment?
Assessment is not only about the diagnostic outcome. Feedback, understanding, and next-step support all matter. A good assessment gives you a clear account of what was found and what it means, whatever the outcome. Autism Detect’s aftercare services include therapy, coaching, and mentoring for those who want support after their assessment.
When to Seek Urgent Help Instead
An autism assessment pathway is not an emergency service. If you or someone you support is in immediate danger, call 999 or go to A&E. For urgent mental health support, call NHS 111 and ask for the mental health option, or contact your local crisis team. ⁶ Do not wait for a diagnostic appointment to address immediate safety needs.
Frequently Asked Questions
Can a GP refuse to refer me for an autism assessment?
A GP is not obliged to refer every person who requests it. NICE guidance says assessment should be considered for adults where persistent features are associated with difficulties in daily life. ¹ Ask for the reason and what would change the decision.
What evidence should I take to a GP appointment?
Specific examples of lifelong patterns across different settings, their impact on daily life, work or relationships, and any professional observations or letters you already have. Concrete examples are more useful than general statements.
Can I ask to see a different GP?
Yes. You can request an appointment with a different GP at the same practice and present your concerns again.
Can a parent refer a child privately without a GP?
Many self-funded private providers accept a parent or carer contacting them directly without a GP referral. Check the provider’s age range, consent requirements and assessment process. This is different from accessing an independent provider through an NHS-funded referral pathway.
Is an initial screening consultation the same as a diagnosis?
No. An initial screening consultation is a short clinician-led session to help determine whether a full assessment is likely to be worthwhile. It is not a diagnostic assessment and does not produce a diagnostic report.
