What does "at the current pace" mean?

We divide the number of people waiting by the number of assessments the service did in the last year. It shows how long someone joining the list today could wait if nothing changes. It is an estimate, not a promise: services can speed up, and some people are seen sooner because of urgency. The NHS standard for non-urgent care is 18 weeks.

What they told us

FOI-TV-2605-055 revised response (7 Aug 2026, issued with the internal review outcome): NHS Trust figures are held by Berkshire Healthcare and Oxford Health (both already reported on this site). For the independent-sector providers the ICB directly contracts: Care ADHD 1,260 adults waiting, Health Harmonie 222, Ciconia 0 (as at 4 August 2026) - 1,482 in total. Adult assessments delivered by independent-sector Right to Choose providers in 2025/26: 3,050 under the former Frimley ICB and 9,347 under the former BOB ICB (12,397 - actual activity April 2025 to January 2026 projected to 12 months). PARTIAL COVERAGE (Right to Choose / independent sector only, NHS trusts excluded) so no effective wait is derived and the figures are not graphed. IAPs: yes - 5,035 adult ADHD assessments commissioned for 2026/27 across 26 named providers (ADHD 360, Atrom Mindcare, Berkeley Psychiatry, Centre for ADHD Research and Excellence, Ciconia Recovery, Clinical Partners, Harley Street Mental Health, Harrow Health, Health Harmonie, Jajawi and Asker, Latahzan, Oakdale Centre, Priory, Psicon, Psychiatry-UK, RTN Medical, Skylight Psychiatry, ProblemShared, Mentalwell, The Owl Centre, Insights Diagnostics, WLC Oxted, Rainbow Diagnostics, Healios, Speech and Language, Montrose); the per-provider allocation was withheld under section 43(2) and the refusal was upheld on internal review.

Figures from individual services come from different dates and some services cover more than one area, so they won't add up to the whole-area total.

Right to Choose: other NHS-funded providers

In England you can ask your GP to refer you to a different NHS-funded provider, often with a shorter wait. These are the waits providers have told us for NHS Thames Valley ICB, shortest first. How Right to Choose works

The budget set by your ICB has limited the number of assessments we can deliver during 2026/27. This means waiting times in your area are longer than our current estimated NHS Right to Choose waiting times. As a result, many patients may wait longer for an assessment than they were expecting when they were originally referred. In excess of 52 weeks means that patients may wait longer than one year from the date you were referred. At present, we are unable to give you a reliable maximum waiting time or tell you exactly when you will be invited to book your appointment.  What happens next?  Where we have already confirmed that your referral has been accepted, and you have completed your forms, you will remain on our waiting list. There is no need to contact us for an update.  We will contact you via email and SMS as soon as we are able to progress your referral.

What is restricting access here

Rules the NHS here has put in place that limit who can be assessed, or how fast.

Adults and children

Capping Right to Choose

This area has caps with 26 adult and 11 child Right to Choose ADHD providers, allowing 5,035 adult and 540 child assessments in 2026/27. It would not share how many each provider is given, saying this was commercially sensitive.

Adults

Extra referral checks (triage)

Since April 2026, adults must have clear written evidence of significant daily difficulties, and be likely to benefit from treatment such as medication, to be referred for ADHD or autism assessment, including through Right to Choose. People seeking a diagnosis mainly for understanding or reassurance are excluded.

    FOI-TV-2605-055 dated 2026-06-29. Thames Valley ICB holds no clean adult ADHD waiting figure — the numbers are held by Berkshire Healthcare NHS FT and Oxford Health NHS FT (the two main community providers). The Frimley area reported 3,606 on a COMBINED ADHD+ASD list (Right to Choose only, including IAP over-performance), which cannot be split to ADHD. The ICB cannot give an expected wait (varies by provider, demand and capacity). Three providers hold direct adult contracts (Ciconia, Health Harmonie, Care ADHD); all others operate under Right to Choose. Condition-combined and partial — not graphed.

No provider holds a direct contract with Thames Valley ICB for child ADHD; all operate under Right to Choose. (The response repeated the same 3,606 combined ADHD+ASD figure given for adults — treated as a templating artefact, not a separate child count.) Not graphed.
