How Right to Choose works in North Central London ICB
The NHS Right to Choose pathway is governed by NHS Patient Choice Guidance published by NHS England on 19 December 2023. It applies to all elective first outpatient referrals, which includes adult ADHD assessment. When you request a referral under this guidance, your GP must submit it via the NHS e-Referral Service (e-RS) to the provider you name. The GP does not need prior approval from North Central London ICB or any commissioner.
North Central London ICB is bound by the NHS Standard Contract, like every ICB in England. That contract is the mechanism that makes NHS Patient Choice Guidance operationally enforceable. The ICB cannot instruct GPs to block Right to Choose referrals on cost grounds. If your GP does block a referral, that refusal should be documented in writing and can be escalated first to the ICB's Patient Experience team and then to NHS England's National Contact Centre.
North Central London ICB serves a population of about 1.4 million people (ONS mid-2024 estimate), making it a mid-sized ICB by population. The ICB area covers Camden, Islington, Haringey, Enfield, Barnet. GP practices in all of these areas are covered by the same Right to Choose entitlement.
It has roughly 260 GP practices. That practice count is approximate and not recently verified, so treat it as a rough scale indicator rather than a current figure.
NHS waiting time in North Central London ICB
Honest note on local data: NHS England does not publish real-time per-ICB waiting times for ADHD assessment. What follows is the national picture; your ICB's wait may be shorter or longer.
What we know
NHS England does not publish a single national average wait for adult ADHD assessment; figures reported by patient groups and academic surveys range from 2 to 7 years depending on ICB. If you know your ICB's current figure, please email us and we will update this page.
To check North Central London ICB's current stated wait: NHS England — Integrated Care in Your Area and then contact North Central London ICB directly via their website or PALS service.
Right to Choose puts you in a different queue, not out of the queue. In an area with no reported cap that queue is usually shorter. Here it is capped, so treat any promise of weeks rather than months with caution and get the current position from the provider.

What to do if your GP refuses
A GP can decline a Right to Choose referral on clinical grounds (i.e., they do not believe the referral threshold under NG87 is met). They cannot decline solely because:
- The provider is not locally commissioned by North Central London ICB.
- The referral would cost more than local provision.
- North Central London ICB does not have a block contract with the provider you have named.
- The local NHS waiting list is long (this is the reason for the referral).
If your GP refuses, ask them to put the refusal in writing and add it to your medical record. Then:
- Step 1 — Escalate to your ICB: Contact North Central London ICB's Patient Experience team (or PALS office). Cite NHS Patient Choice Guidance (NHS England, 19 December 2023) and the NHS Standard Contract.
- Step 2 — NHS England National Contact Centre: 0300 311 22 33. They can instruct the ICB and, ultimately, the GP practice.
- Step 3 — Parliamentary and Health Service Ombudsman (PHSO), if you have exhausted the above and the GP's refusal was not on clinical grounds.

Frequently asked questions for North Central London ICB
How long does North Central London ICB take to action a Right to Choose letter?
Once your GP submits the referral via NHS e-Referral Service (e-RS), the provider, not the ICB, manages the booking. North Central London ICB does not need to approve or process the referral; the NHS Standard Contract requires providers to accept e-RS referrals directly. Contact times vary, are set by the provider, and are not published. Ask the provider for their current position when you check availability. If the GP delays submitting, ask them in writing and give a 10-working-day deadline, citing NHS Patient Choice Guidance (2023).
Can I use Right to Choose if I'm registered with a GP in Camden?
Yes. Any GP practice in North Central London ICB — including practices in Camden and Islington — is covered by the same NHS Patient Choice Guidance entitlement. Registration with a practice anywhere in North Central London ICB is sufficient. The right does not depend on which GP practice you're with, which neighbourhood you live in, or whether your practice has used Right to Choose before.
My GP in Islington said North Central London ICB doesn't commission ADHD assessment externally — is that right?
That framing is not accurate when a patient invokes their legal Right to Choose. NHS Patient Choice Guidance (2023) explicitly states that a referral under the right to choice does not require prior commissioner approval. Whether North Central London ICB holds a block contract with a given provider is irrelevant — the GP must submit the referral via e-RS if you invoke the guidance and clinical referral criteria under NICE guideline NG87 (Attention deficit hyperactivity disorder: diagnosis and management) are met.
Will my GP in North Central London ICB prescribe ADHD medication after a Right to Choose diagnosis?
Shared-care prescribing after a Right to Choose ADHD diagnosis is GP-discretionary. There is no NHS rule requiring a GP to take over prescribing from the diagnosing provider. The Right to Choose letter separately asks your GP to confirm their position on shared care in writing, so you know where you stand before committing to any private bridge prescription. Shared-care policies vary between practices within North Central London ICB.
What if North Central London ICB or my GP doesn't respond after I send the letter?
If your GP doesn't respond within 10 working days, follow up in writing referencing the letter and asking for a response date. If there is still no response after a further 5 working days, escalate to North Central London ICB's Patient Experience team (or PALS). If the ICB doesn't resolve it within 20 working days, you can escalate to NHS England's National Contact Centre on 0300 311 22 33. Our Tier 2 letter drafts the ICB escalation letter for you upfront.
