Starting secondary school with autism: a guide for parents (2026)
The transition from primary to secondary school is one of the most significant challenges many autistic children face. A new building, multiple teachers, a complex
If you are based in Bristol and looking for a private autism assessment for your child or yourself, this guide covers everything you need: what to expect, how much to pay, how to find a quality provider, and what to do once you have a diagnosis.
In Bristol and the South West, the current NHS wait for a child autism assessment is typically two to four years. For many families, this is simply too long — particularly when a child is struggling at school, approaching a critical transition, or needs a diagnosis to access DLA or apply for an EHCP.
Private assessment in Bristol typically delivers results within four to eight weeks of booking.
Bristol costs are broadly in line with the national average, though some providers in the city centre charge a modest premium. Providers in Bath, Somerset, and Gloucestershire are often slightly less expensive and easily accessible.
| Assessment type | Typical cost | What is included |
| Basic assessment | £500–£800 | Single clinician, written report |
| Standard full assessment (recommended) | £900–£1,300 | Multi-clinician, ADOS-2, full report, feedback session |
| Comprehensive MDT assessment | £1,400–£2,000 | Full MDT team, detailed report with recommendations |
| Adult autism assessment | £600–£1,600 | Varies by provider — always ask for a full breakdown |
Bath, Taunton, and Gloucestershire all have providers accessible from Bristol. Many offer hybrid assessments with some elements delivered remotely.
Quality varies between providers. Here are the questions to ask before booking with any assessor in or near Bristol:
Yes — a private autism diagnosis carries exactly the same legal weight as an NHS one, and is accepted by all local authorities, schools, and the DWP across the UK. Bristol City Council is legally required to accept a private autism diagnosis for EHCP needs assessment purposes.
The only requirement is that the assessment was carried out by a qualified and registered clinician using validated tools such as the ADOS-2.
Bristol has an active SEND parent community. SEND Bristol (sendbristol.org) is an independent support group with local knowledge of the Bristol EHCP and tribunal process.
Bristol City Council’s SEND Local Offer is at bristol.gov.uk/send-local-offer and includes a searchable directory of local services.
Provide a copy of the diagnostic report to your child’s SENCO immediately. Request a meeting to discuss what support the school can put in place. If current provision is insufficient, put your EHCP request in writing.
Call 0800 121 4600 to request the DLA1 Child form. Include the diagnostic report with your application. DLA for an autistic child can be worth £28.70–£184.30 per week depending on need.
Write to your local authority’s SEND team requesting a needs assessment under the Children and Families Act 2014. Include the diagnostic report. The local authority must respond within six weeks.
Your local Parent Carer Forum is an invaluable source of advice on local SEND provision and the EHCP process in your specific area. Find yours at nnpcf.org.uk.
How long does a private autism assessment take in Bristol?
From booking to receiving your written report, most Bristol providers complete the process in four to eight weeks. Some offer expedited timelines for an additional fee — useful if you have an urgent EHCP review or school placement decision.
Do I need a GP referral for a private autism assessment?
No. One of the key advantages of going private is that you can self-refer directly. You do not need to go through your GP, although it is worth informing them that an assessment is taking place.
Will a private autism diagnosis be accepted for an EHCP in my area?
Yes. All local authorities are legally required to accept a valid private autism diagnosis for EHCP needs assessment purposes. This applies across Bristol and the South West as it does everywhere in the UK.
Can adults get a private autism assessment?
Yes — adult autism assessment is available from private providers in and around Bristol. The process is similar to child assessment but adapted for adult presentation. NHS waits for adult assessment are often even longer than for children, making private assessment the realistic route for most adults.
