Autism diagnosis in Northern Ireland: complete guide (2026)

Which HSC Trust covers my area?

Referrals go to the Trust that covers where you live. If you're not sure which one that is, use this as a rough guide, then confirm with your GP:

How autism diagnosis works

Autism assessment is organised through Northern Ireland's five HSC Trusts. Each Trust manages its own services, so referral routes, assessment teams, and waiting times can differ depending on where you live.

A regional "Six Steps of Autism Care" framework provides a common approach to assessment. It includes a recommended maximum wait of 13 weeks from referral to first appointment, although this is a care standard rather than a legal deadline, and it is frequently exceeded.

Services operate within the Autism Act (Northern Ireland) 2011, as amended by the Autism (Amendment) Act (Northern Ireland) 2022. This legislation provides for a regional autism strategy and includes measures intended to improve services and reduce waiting times. In practice, however, demand continues to exceed assessment capacity, and waiting times vary considerably between Trusts.

Waiting times

Demand continues to outpace assessment capacity. The most recent published figures, from March 2026, showed more than 8,000 children had been waiting longer than two years for an assessment, including over 2,600 in the Belfast Trust and 1,300 in the Western Trust, with adults facing similarly long waits. Autism NI has reported waits of up to five years for both children and adults in the worst-affected Trusts.

Official waiting-time statistics are not published consistently across all five Trusts, so treat any single figure as a snapshot rather than the current picture, and check with your local Trust for the latest position.

Getting an autism diagnosis for a child

1. Get a referral

A child can usually be referred by their GP, health visitor, or school to the local Trust's paediatric autism or ASD service. Some Trusts also accept referrals directly from a parent or carer.

Age limits vary slightly between Trusts, but most paediatric services assess children from around age two through to 18.

2. Wait for assessment

The Trust will triage the referral and decide whether an autism assessment is appropriate. If accepted, the child joins the Trust's waiting list.

3. Attend the assessment

Assessment is usually carried out by a multidisciplinary team and may include:

• a developmental history from parents or carers
• direct observation of the child
• clinical interviews
• standardised assessment tools such as ADOS-2, ADI-R, or DISCO
• input from paediatrics, speech and language therapy, or educational psychology, where appropriate

The exact process varies between Trusts.

Other support

An autism assessment is only one way of identifying a child's needs. If a child is struggling and needs support, families don't necessarily have to wait for a formal autism diagnosis before asking for help.

Under Articles 17 and 18 of the Children (Northern Ireland) Order 1995, Health and Social Care Trusts have a duty to assess children who may be "in need" and consider what support they require. This is separate from the clinical process of diagnosing autism, so a child can be assessed by social services while still waiting for an autism assessment.

Trusts generally use the UNOCINI framework for this, which can look at a child's health, development, education, family circumstances, and care needs.

If your child needs support now, it's worth asking your Trust what help is available rather than assuming you have to wait until the autism assessment is complete.

Getting an autism diagnosis as an adult in Northern Ireland

Adults usually start by speaking to their GP, who can refer them to the local Trust's adult autism assessment and diagnostic service.

The service varies between Trusts. Some, including Belfast, have a dedicated adult autism team, while elsewhere referrals may be handled through adult mental health or psychiatry services. This can affect both the assessment process and the wait.

An adult autism assessment typically includes:

• a clinical interview
• a detailed developmental history
• information from family members or someone who knew you in childhood, where available
• standardised assessment tools, where appropriate

There is no upper age limit for an autism assessment. Many people are diagnosed for the first time in adulthood, particularly if they were not identified as autistic when they were younger.

Tip: ask your GP which service your referral will go to, and whether there is anything you can provide to support it, such as school records or information from someone who knew you as a child.

Right to Choose and private autism assessment

Does Right to Choose apply in Northern Ireland?

No. NHS Right to Choose applies to NHS patients in England and does not operate in Northern Ireland. In Northern Ireland, autism assessment is commissioned only through the local HSC Trusts.

Can I pay for a private assessment?

Yes. Private autism assessments are available in Northern Ireland and from UK-wide providers. If you are considering one, check:

• RQIA registration: the provider should be registered with the Regulation and Quality Improvement Authority, where registration is required.
• Clinician qualifications: check whether the assessment is led by an appropriately registered clinician, such as a GMC- or HCPC-registered professional.
• Assessment methods: ask which recognised diagnostic tools and clinical methods are used.
• What the fee includes: confirm whether the quoted price covers the full assessment, report, and any follow-up.
• Whether your Trust will accept the report: ask before paying, since Trusts differ in how they review private diagnoses, and some, including the Northern Trust, can take four to six weeks to do so.

Prices vary substantially by provider and by the type of assessment, and typically range from a few hundred pounds for an initial screening to upwards of £1,500 for a full diagnostic assessment. Always check current fees directly with the provider. See our NHS vs private autism assessment guide for more on comparing providers.

After an autism diagnosis

What happens after diagnosis varies between Trusts. Depending on where you live, you may be offered information about autism, psychoeducation or post-diagnostic sessions, signposting to local services, or advice about education, employment, or benefits.

Support can be limited, so ask the diagnosing team what is available locally. You can also seek help from autism charities and community organisations while waiting for, or after receiving, a diagnosis.

Your diagnostic report

Keep a copy of your full diagnostic report. It may be useful when requesting reasonable adjustments, applying for support, or explaining your needs to education or employment services.

In Northern Ireland, workplace disability rights are covered by the Disability Discrimination Act 1995, as amended by the Autism Act (Northern Ireland) 2011, rather than the Equality Act 2010, which does not apply there. Education has a separate legal framework, including the Special Educational Needs and Disability Order (SENDO) 2005.

A diagnosis can also be relevant when applying for Personal Independence Payment (PIP), administered in Northern Ireland by the Department for Communities. A diagnosis does not automatically qualify someone for PIP; eligibility depends on how a person's condition affects their daily living and mobility.

Where to get further support

Autism NI provides information, a helpline, and support services across Northern Ireland. The National Autistic Society also runs specialist services in Northern Ireland. Other charities and local community groups may offer support without requiring a formal diagnosis.
