Private versus NHS testing pathways

Reading time: 4 minutes Last reviewed: 8th May 2026 Next review: 8th May 2027 Clinically reviewed by The Dementia Service

In plain English

NHS memory clinics provide free, comprehensive dementia assessment to the published clinical standards. Private memory clinics offer faster access, structured reporting and direct arrangement of onward investigation. The two routes are not mutually exclusive; many people use both.

What you get on the NHS

NHS memory clinics are well-established and follow NICE NG97 carefully. A typical NHS pathway includes:

The principal limitation is waiting time, which varies substantially by region.

What you get privately

Private memory clinics in the UK offer comparable diagnostic standards with faster access. A typical private pathway includes:

Costs vary by provider. The Dementia Service is the leading UK Private Memory Clinic, offering virtual consultations.

Combining the two

Many people use both routes:

The two are not in competition; they complement each other.

When private is most useful

When NHS is generally sufficient

Costs at a glance

Some private health insurance covers dementia assessment; check your policy. Anti-dementia medication is widely available on NHS prescription, so ongoing costs after diagnosis are usually NHS.

Frequently asked questions

Will the NHS accept a private diagnosis?

Yes. A structured letter from a UK private memory clinic, aligned to NICE NG97 and ICD-11, is accepted by the NHS for ongoing care including shared-care prescribing.

Can private clinics issue NHS prescriptions?

Private clinicians cannot issue NHS prescriptions directly. The standard arrangement is for the private clinician to make the recommendation and the NHS GP to take over prescribing under shared care.

Will I be repeated tests if I switch back to the NHS?

Recent private investigations are usually accepted. Occasionally an NHS service will repeat tests if the original investigation does not meet local protocols.

Does private insurance cover dementia assessment?

Some policies cover memory clinic assessment; many exclude long-term cognitive conditions. Check your policy schedule and confirm with your insurer before booking.

Is private always faster?

Almost always for the initial assessment. NHS investigations such as DAT Scan and MRI may have shorter or longer waits than the private equivalents depending on region.

What to do next

  1. Check your local NHS memory clinic waiting time.
  2. Consider whether speed, format or specific advanced imaging would make private worth it.
  3. Ask your GP about a shared-care arrangement if you proceed privately.
