Current waiting times for adult ADHD (assessment and titration)

Last reviewed: October 2026

Summary: For assessment, most patients are booked in within 1-2 weeks of returning their forms. If you're waiting to start medication for ADHD, a period known as ‘titration’, please make sure you have completed all relevant forms and returned them to us. We also recommend you save our telephone number (+44 20 4642 7098), so you don’t miss our calls.  
 
Please be assured, our teams are working hard to reduce waiting times across the board.

We know that waiting isn’t easy, especially when you’re ready to take the next step. So, whether you’re waiting for assessment or to begin titration, we’ll always be upfront about timelines.  

The times below reflect typical patient experiences over recent months and are reviewed every few weeks. Your wait may be shorter or longer, depending on demand, clinical capacity and NHS funding in your area. It also depends on how quickly your GP completes your referral, how quickly we’re able to process it, and how quickly you return your completed pre-assessment forms to us. 

NHS ADHD waiting times have grown recently – there are several reasons for this. Read about these in detail and find out some useful next steps: ‘Understanding ADHD waiting times’. 

NHS Right to Choose patients  

• After your GP refers you to us, we’ll usually send your pre-assessment forms within 10 days.

• Once you return your assessment forms, we’ll typically be in touch within 1-2 weeks to book your appointment.  

Private patients 

• After you’ve registered for an assessment, we’ll usually send you your pre-assessment forms within 7 days.

• Once you return your assessment forms, we’ll typically be in touch within 1-2 weeks to book your appointment. 

Patients with an existing ADHD diagnosis 

• If you've already been diagnosed with ADHD, we may need to review your diagnosis before treatment can begin. This involves checking that your existing diagnosis meets NHS standards.

• Timelines for this can vary. This is due to referral volumes, what information you provide to us regarding your existing diagnosis and wider NHS pressures.

• If you're going through this process, please know that you haven't been forgotten. We’ll be in touch. 

Waiting to start titration can be a difficult time, so we want to be as clear as we can about the timelines relating to your care. 

Through 2026, we saw a surge in demand for our titration service. To tackle this, we’ve significantly increased the number of titration appointments we provide and rolled out a comprehensive plan to work through the waiting list. 

What this means

Currently, the waiting time for titration is under three months from the point at which we receive your physical health forms. It's important to return your forms to us so that titration can start promptly.

Please note:

• If you’re currently waiting, newer patients won’t jump the queue ahead of you.

• We see patients on a first-come-first-served basis, in order of when they completed their forms. 

• The only exceptions to this are a very small number of cases – fewer than 5% – when a patient must be seen sooner because of urgent clinical need.

We’re working hard to continue to increase the number of patients we see each week and reduce waiting times further. We’ll keep this article updated regularly, and provide any other relevant communications, as and when our waiting times change.

• Extra tests are needed, or coordination required with your GP or hospital

• Clinical reviews are required – these are carried out by a prescriber and cover your physical health, medication suitability and co-existing conditions

• High volumes of patients waiting to begin titration

• Missing or incomplete forms

• Regional NHS funding decisions 

What you can do to help avoid delays 

• Save our number +44 20 4642 7098 so you don’t miss our call

• Unless your wait has gone significantly beyond the timelines above, please avoid sending the same message more than once. This means we can keep the queue moving along for everyone. If you do need help, we recommend you contact us via our live chat rather than using the phone line – we’ll be able to get back to you sooner. 

I've submitted an NHS Right to Choose referral – what happens next? 

Your GP will send your referral to us directly, and it will be processed in the same way as any other NHS referral. We're unable to fast-track referrals for patients who are, or have previously been, on our private pathway. If you've paid for a private assessment that you no longer wish to attend, please contact us on via the live chat or on 020 4525 0709 to discuss your options. 

Can you tell me when my ADHD assessment or titration appointment will be? 

We’re not able to give individual timeframes as all cases are reviewed in order, with clinical safety as the priority. We’re sorry we can’t be more specific.   

How are appointments allocated?  

Appointments are allocated based on when a patient completes their pre-assessment forms and becomes ready to book, not solely on their referral date. All cases are then reviewed in order, with clinical safety as the priority, meaning patients identified as high risk may be seen sooner.   

This is why two people referred at the same time may receive appointments at different points – one may have completed their forms earlier or been prioritised on clinical grounds. 

I contacted you but haven’t heard back – is everything ok? 

There’s currently a 1-2 week turnaround on general queries, but we will get back to you. To help keep the queue moving for everyone, please avoid sending the same message more than once. If you need a faster response, we recommend you contact us via our live chat rather than using the phone line – we’ll be able to get back to you sooner.
