NHS Right to Choose OnlineADHDAutismChildren2–14 weeks (varies by ICB and pathway; ~8–10 weeks typical remote wait)NHS-funded via Right to Choose (no private self-pay pathway listed)
Paloma Health
Specialist children and young people's autism (from age 2) and ADHD (from age 8) assessment service, up to age 18. ADHD assessment is remote-only; autism and joint ADHD+autism assessments offer a hybrid option via two physical hubs — The Senate, Southernhay Gardens, Exeter EX1 1UG, and Cavell House & Austin House, Stannard Place, St Crispins Rd, Norwich NR3 1YE. Typical remote waits (most English ICBs): ADHD ~9 weeks, autism ~8 weeks, joint ADHD+autism ~10 weeks. Hybrid waits vary by hub and age band: Norwich offers a notably fast ~2-week hybrid option (ages 6–18 autism, 8–18 joint); Exeter hybrid runs ~11–12 weeks (ages 2–4 and 5–18 autism, 8–18 joint). NHS Right to Choose only — no self-pay pathway. Genuinely nationwide across England (accepts referrals from GPs/ICBs in all 42 English ICBs, not restricted to the two hub areas) — do not geo-restrict to Exeter/Norwich despite the physical hubs. NHS Right to Choose does not extend to Scotland/Wales/Northern Ireland, so this provider does not serve those nations. Registered with CQC as Your Patient Choice Limited. Rated 4.9/5 on Trustpilot (~220 reviews, verified). Wait times and ICB pause status change often — check paloma.health/waiting-times for the current figure before referring.
