Aviva's Healthier Solutions terms name ADHD and autism directly, and they exclude them: the mental health part of the policy does not pay for treatment of learning difficulties or developmental or behavioural problems, and that includes the diagnostic tests used to assess them. So if you are looking at Aviva for yourself or a child with an ADHD or autism assessment in mind, the decision in front of you is whether the rest of what an Aviva policy pays for is worth buying anyway. Pricing that is free: once your details are in the quote form, an FCA-authorised broker phones you, without charge, with Aviva's figures and other insurers' on the same options.
This page sets out the exact Aviva sentence, what Aviva's mental health cover does and does not reach, the few benefits that sit near the subject, and the chronic and pre-existing rules that bear on a diagnosis. How other insurers word the same exclusion is compared on private health insurance and ADHD in the UK.
Does Aviva health insurance cover ADHD or autism? The exclusion, word for word
The sentence sits in the "Mental health" benefit term of the Healthier Solutions terms and conditions, on page 13 of the PDF (numbered 11 in print). Under "We do not cover:", the second of three bullets reads:
"treatment, including diagnostic tests to treat or assess learning difficulties or developmental or behavioural problems such as attention deficit hyperactivity disorder (ADHD) and autism spectrum disorder, or"
The wording is identical in the two issues this page was checked against: the April 2025 issue (print code GEN6842 04/2025) and the March 2026 issue (print code GEN6842 03/2026), whose document title describes it as applying to policies started or renewed before 1 November 2026. Both carry it on the same PDF page. A policy that starts or renews later may be written on a newer issue, so the issue named in your own policy documents is the one that counts.
Three things follow from the words themselves. ADHD and autism spectrum disorder are named as examples, so the sentence does not depend on how either condition is classified. It reaches assessment as well as treatment, because "diagnostic tests to treat or assess" are inside the exclusion. And it covers a wider group than the two named conditions, since "learning difficulties or developmental or behavioural problems" is the category and ADHD and autism are given "such as".
Other benefits in the terms sit near the subject, and later sections work through each of them against this exclusion:

What Aviva's mental health cover does, and does not do, for ADHD and autism
The benefit term opens with its purpose: "We cover acute mental health conditions. This means we will cover treatment which aims to lead to your full recovery." The two bullets either side of the ADHD sentence narrow it further. Aviva does not pay for "treatment that is given solely to alleviate symptoms", and it does not pay for "chronic mental health conditions".
On page 14 (12 in print) the same term says when a mental health condition is chronic: if it meets the policy's general definition of a chronic condition, or if Aviva has "paid for your treatment for that condition or a related mental health condition during three separate policy years", whether or not those years ran one after another. It then closes with a routing rule: "Treatment related to mental health conditions will not be covered under any other benefit on this policy."
The mental health money in the policy runs through that term. The benefit table on page 6 (4 in print) has a row for "Mental health treatment as an out-patient", up to £2,000, "On GP referral to a psychiatric therapist or psychiatric specialist", and it points the reader to the mental health benefit term. Option F on page 10 (8 in print) adds in-patient and day-patient mental health treatment, in full for up to 28 days per member each policy year, with the same pointer. Neither row lifts the exclusion; both are paid subject to it.
Put together, for a reader thinking about ADHD or autism:
- Not paid: an assessment or diagnostic tests for ADHD, autism or another developmental or behavioural problem; ongoing treatment of those conditions; treatment aimed only at easing symptoms; and any mental health condition that has become chronic under the definition above.
- What the cover is for: treatment of an acute mental health condition aimed at full recovery, within the out-patient limit on the options chosen, and in hospital only if option F was added.
- Which options carry it: page 24 (22 in print) says out-patient mental health treatment comes from the mental health benefit in the full out-patient and the £500 or £1,000 reduced out-patient options, and that on reduced out-patient cover with benefit reduction C2, or the £0 limit, without option F, Aviva does "not cover treatment of psychiatric, psychogeriatric or mental health illnesses or conditions of any kind, such as stress".
A question the terms leave to Aviva is how it would handle a separate acute condition, such as anxiety or low mood, in someone who also has ADHD or autism; a broker will take that up with Aviva for you, at no charge, before you commit. The full mental health benefit, with its limits on each option, is read on our page about Aviva mental health cover.
Could an assessment be claimed under another part of the policy?
Readers sometimes hope an assessment could go through as an ordinary specialist appointment. The terms point the other way. The ADHD sentence names diagnostic tests to assess, and the routing rule on page 14 keeps treatment related to mental health conditions out of every other benefit. Three other clauses are worth knowing because they come up when an assessment is being planned.
A GP's own tests. In its standard form, the GP exclusion on page 23 (21 in print) rules out treatment by a GP and "treatment or diagnostic tests requested by a GP, such as X-rays, blood tests and scans (other than two speech therapy sessions per child)". Option D, if chosen, swaps in a different version.
Specialist consultations on reduced cover. Page 24 (22 in print) allows "up to two consultations with a specialist each policy year, and limited diagnostic tests" for a member on reduced out-patient cover with benefit reduction C2. That is an allowance for out-patient care in general; it does not override the mental health term's exclusion of diagnostic tests to assess ADHD or autism.
Tests linked to a hospital stay. The C2 row on page 9 (7 in print) makes diagnostic tests payable only where they lead directly to in-patient or day-patient treatment "that is covered by the policy", or follow it within six months for the same condition. An ADHD or autism assessment does not lead to covered treatment, because the treatment is excluded too.
These clauses are compared with other insurers' wording on our page about out-patient cover. If an appointment is described to you as a general paediatric or neurology consultation, ask for Aviva's position in writing before booking it on the policy.
Speech therapy for children: the one nearby benefit
The benefit table on page 6 (4 in print) has a row for GP-referred treatment by a speech therapist for children: "Up to 2 speech therapy sessions" for each child covered. Its benefit term on page 15 (13 in print) runs until the renewal date after the child's 18th birthday and includes speech therapy needed for developmental delay. Developmental delay is a reason for the sessions, not an assessment of ADHD or autism, and the page 13 exclusion still stands beside it. Two sessions is a small allowance, not a course of therapy.
A footnote marker follows the word "children" in the table row. In the table it marks benefits whose claims do not affect the no claim discount, which is worth knowing if a child might use both sessions each year. The row is set beside the GP exclusion that names it on our page about what a child's health insurance plan costs, and Aviva health insurance for children covers the family side of the policy.
If you are weighing a policy for a child, the most useful thing to give a broker is a short list of the services you expect to use, named one by one, so that the comparison asks about speech therapy, a paediatric consultation and talking therapy separately, rather than about "autism cover" as one thing.
Chronic and pre-existing wording: how they bear on a diagnosis
Two further rules depend on a condition's history rather than its name, and they matter for anything a policy might pay around a diagnosis. Aviva's terms exclude chronic conditions (page 3, 1 in print) and define one by a list of characteristics, any one of which is enough. The list starts with a need for "ongoing or long-term monitoring", by way of consultations, examinations, check-ups or tests, and also includes a condition that "continues indefinitely" or "has no known cure". For mental health, page 14 adds the three-policy-years test described above. Our page on reading an Aviva quote sets the chronic clause beside the rest of a quotation.
The second rule is about the past. On page 27 (25 in print), Aviva's terms say they do not cover treatment of a pre-existing condition, "or any related or associated condition", unless the member "advised us of that condition in writing" when applying and Aviva then put no exclusion on it, or it is not excluded by the policy. The first phrase widens what could be caught beyond the diagnosis itself. Whether a concern raised with a GP or a place on a waiting list would count as pre-existing is something to go through with a broker before you apply, and the call-back is free. How it plays out depends on how the policy was underwritten, which our Aviva underwriting page explains, and the general reading of past conditions in a mental health setting is on the page about pre-existing conditions.
So for someone with an ADHD or autism diagnosis, or waiting for one, the ADHD and autism exclusion sets the condition itself aside, and the chronic and pre-existing rules may reach conditions connected with it. What the policy would still pay for, such as an unrelated operation or a new acute condition, is the part worth pricing.
Separately from any decision about insurance: if you are an adult seeking an assessment for yourself, or a parent looking into one for your child, the National Autistic Society (autism.org.uk) and the NHS website (nhs.uk) both explain how the process works, and a GP is the usual way into an NHS referral whatever you decide about cover.
What to ask a broker before buying Aviva
- Which issue of the Healthier Solutions terms would my policy be written on, and is the page 13 "Mental health" exclusion of ADHD, autism and diagnostic tests worded the same in it?
- If someone in the household already has a diagnosis, or is on a waiting list, how would Aviva treat related conditions under its pre-existing wording on the underwriting I am being quoted?
- Would Aviva pay for an acute condition such as anxiety in a member who also has ADHD or autism, and what would decide it?
- Which out-patient option is on this quote, and does it carry out-patient mental health treatment at all?
- Is option F included, and is it worth having for this household given the exclusion?
- For a child, how would the two speech therapy sessions and the developmental delay wording apply?
Ask for any answer that changes your decision to be confirmed in writing, and keep it with your policy papers, dated. If you tell Aviva about a concern when you apply, describe it in your own words and keep a copy of what you sent.
Aviva, ADHD and autism: short answers
Does Aviva health insurance pay for an ADHD assessment?
No, on the wording of the April 2025 and March 2026 issues. The "Mental health" benefit term excludes "diagnostic tests to treat or assess" developmental or behavioural problems, naming ADHD and autism spectrum disorder.
Does Aviva medical insurance cover ADHD medication or ongoing treatment?
The same sentence excludes treatment of ADHD as well as its assessment, and the term separately excludes treatment given only to ease symptoms and chronic mental health conditions.
Does Aviva cover autism for a child?
Treatment and assessment of autism spectrum disorder are excluded. The nearest benefit is two GP-referred speech therapy sessions per child, whose benefit term includes speech therapy needed for developmental delay.
Does adding Aviva's mental health option change the answer?
No. Option F adds hospital cover for mental health treatment, but it is paid under the "Mental health" benefit term, which is where the ADHD and autism exclusion sits.
Is the ADHD wording different in Aviva's March 2026 terms?
No. The April 2025 and March 2026 issues carry the same sentence on the same PDF page, page 13. The March 2026 copy is titled for policies started or renewed before 1 November 2026, so a policy beginning after that date should be checked against whichever issue Aviva sends with it.
