The Guardian reported in January 2026 that NHS ADHD spending in England was projected to be £164m over budget, with private providers playing a growing role.

When patients cannot get timely answers through standard NHS routes, they often look elsewhere. That may mean self-funded private care, employer benefits, private assessments or insurance.

But ADHD also shows why the private route needs careful explanation.

Demand does not automatically mean insurance cover

Rising private healthcare demand does not mean every private route is covered by private medical insurance.

ADHD assessments are a good example.

Many people assume that if something is health-related and private, it must be something PMI can cover. That is not always true.

PMI is generally designed around eligible new acute conditions. ADHD is often handled differently because it is neurodevelopmental and may involve assessment, long-term support, medication review and school or occupational impact.

That means PMI may not be the right product if someone’s main aim is to fund ADHD assessment or ongoing ADHD care.

What this means for families

Families facing long waits may feel pushed into private options.

That is understandable. If a child is struggling at school or an adult is unable to work properly, waiting can have real consequences.

But before buying PMI, families should separate three questions:

1. Do we want faster private access generally?

2. Do we specifically want ADHD or autism assessment?

3. Would the policy actually cover that need?

Those are different questions.

Family PMI may still be useful for eligible private diagnosis and treatment, including some scans, consultations, surgery, cancer care or mental health support where included.

But it may not cover neurodevelopmental assessment or long-term support.

A private-provider boom can create confusion

When private clinics become more visible, patients may see “private healthcare” and “private medical insurance” as the same thing.

They are not. Self-funded private healthcare means paying directly for care. PMI means making a claim under an insurance policy, subject to underwriting, exclusions, policy limits and authorisation. A private clinic may provide a service that your insurer does not cover. That distinction matters before families commit to a policy.

The bottom line

The ADHD spending story highlights growing pressure on NHS access and rising reliance on private routes.

But it also shows why PMI must be explained carefully.

Private medical insurance can be valuable when it is matched to the right need. It can be disappointing when people expect it to cover services that are excluded or limited.

For ADHD, autism and developmental concerns, families should ask very direct questions before buying cover.
