For most adults in Ireland, getting an autism assessment means paying for a private one. The HSE's patient guidance says plainly that "the HSE does not provide autism assessments for adults." Its national autism protocol, in force since 25 March 2026, says much the same thing: in most areas there is no public team, and "regretfully this generally means seeking a private assessment, for those with means."
In November 2026 we checked the prices Irish clinics publish. An adult autism assessment cost between €1,400 and €1,950, and one Dublin clinic charged €2,800 to assess autism and ADHD together. You do not need a GP referral to book, though a referral can affect whether you can claim tax relief. This page covers the Irish route in detail: who is qualified to assess you, what the appointments involve, what the report should contain, and what support exists afterwards. If you want the side-by-side comparison with England's waiting lists, that is in our England and Ireland overview.
There are two official HSE positions, and they are worded differently.
The HSE's patient page on How to get assessed for autism is short: adults "will need to pay for a private assessment by a psychologist," and "you do not need a referral from a GP to see a psychologist about an autism assessment."
The HSE National Protocol for Autism Assessment and Intervention Pathways, effective from 25 March 2026, is the document clinicians work from, and it goes into more detail. It says that in principle an adult can be screened and assessed through "any service which the person is currently receiving, such as primary care, mental health, or disability services." It also admits that "in most areas adult disability services do not have teams that can undertake Autism assessments." It calls this "inequitable" and recommends that each of the six Regional Health Areas should have at least one public team for adult autism assessments. That is a recommendation, not a service that exists yet.
So if a public service already looks after you (a community mental health team, for example), ask whether it can assess you or refer you on. Otherwise, expect to go private. AsIAm, Ireland's national autism charity, agrees: "Currently there are no public teams in Ireland dedicated to assessing Autism in adults." The HSE also says you can use its services without a formal diagnosis.
Most private adult assessments in Ireland are carried out by psychologists. Before you book, you should know that psychology is not yet a state-regulated profession here. CORU, the health and social care regulator, says its first three registers (for clinical, counselling and educational psychologists) are "now expected in 2027." After each register opens there is a two-year transition period, and only once that ends is the professional title legally protected. Until then, anyone can call themselves a psychologist.
For now, there are two practical checks:
The HSE patient page points to the PSI and the Irish Association for Counselling and Psychotherapy (IACP) directories. The newer protocol is stricter, so ask any practitioner what their professional training is.
Some adults are assessed by a consultant psychiatrist, either alone or as part of a team. Every doctor practising in Ireland has to be on the Medical Council register, and a doctor can only practise independently as a specialist with specialist registration. You can check both yourself on the Medical Council's "Check the Register" page.
Ireland's protocol and England's NICE adult autism guideline (CG142) both recommend team-based assessment where possible. Some private assessments here are done by one psychologist, some by a team, so ask which you are booking. Also ask whether the assessor is experienced in telling autism apart from conditions that can look similar, which the protocol treats as a core competence.
The HSE describes an adult assessment as an interview with you, questionnaires about yourself, a conversation with someone who knew you as a child, and a review of any GP reports about other health conditions. The protocol adds what the interview should cover: your development, what growing up was like, education or work, relationships, strengths, physical and mental health, and risk, including self-harm.
How long it takes depends on the clinic. One Sligo clinic describes three hours with the psychologist. A Dublin clinic lists five appointments: a one-hour interview, a two-hour follow-up, a 90-minute interview with a relative or friend, a cognitive assessment and a feedback session.
Clinic websites often mention these by name, so it helps to know what they are:
Neither one is a test you pass or fail, and neither makes the diagnosis. The HSE protocol says that all of the tools it lists for adults are "to assist clinical judgement, none are valid as stand-alone diagnostic instruments." It also says that none of the instruments routinely used in Ireland have Irish norms, that most cannot pick up masking, and that "there are no psychometric norms for adult Autism assessment." The diagnosis itself is a clinical judgement made against ICD-11 or DSM-5 criteria. So if a clinic calls one tool the "gold standard", treat that as marketing.
Many late-diagnosed adults have no parent who can describe their early childhood. NICE says assessment should involve an informant "where possible" or use documents such as school reports. AsIAm says there is "no requirement or expectation" that you involve anyone, and that you can choose a professional who does not need this. The HSE protocol does expect some developmental information, so old school reports and other records from the time are worth digging out. Our piece on being diagnosed late has more on preparing.
These are prices Irish providers publish on their own websites, checked on 1 November 2026. They show the range; they are not recommendations.
Before you compare, check three things:
According to the HSE, the report will say whether you are autistic, not autistic, or whether it is unclear at this stage. It should also cover your strengths, what you might need help with and which services could provide it, and whether the team noticed signs of other conditions, such as ADHD, that may need their own assessment.
The HSE protocol also matters if you plan to use a private report with public bodies. It says that for publicly funded agencies to accept a private practitioner's report, the report "should include" a written statement of how the practitioner meets the protocol's standards. Ask before you book whether your report will include one.
For college, the DARE admissions scheme (only for school leavers under 23) accepts reports from a consultant psychiatrist or psychologist, among others, if they reference diagnostic criteria and list the tests used.
Many adults wonder about both. Since DSM-5, autism and ADHD can be diagnosed in the same person; earlier editions did not allow it. How often they occur together is much less settled. A 2022 review notes published estimates that 50–70% of autistic people also have ADHD, but its authors question whether some attention difficulties in autism are really ADHD at all. Telling the two apart is exactly why the HSE protocol puts "difficult differential assessment" between autism and ADHD in its more detailed tier of assessment.
Two practical points:
A diagnosis can also help make sense of experiences like autistic burnout, which is often mistaken for depression, and of sleep difficulties, which are common in autistic adults.
No. The HSE says you can go directly to a psychologist. Some private clinicians still ask for one, though, and Revenue's guidance links tax relief on a psychologist's fees to a referral from a doctor.
The HSE protocol says private reports should include a written statement of how the practitioner meets its standards for publicly funded agencies to accept them. Ask your assessor whether theirs will include one.
The HSE says reports can conclude that a person is autistic, not autistic, or that it is unclear for now. AsIAm points out that an assessment can still be useful because it may identify something else, such as ADHD or anxiety. You are paying for the assessment, not for a particular result.
Some Irish providers work fully online; others require at least one in-person session. Ask how each part, including any observation, will be done.
