Clinical Services

Clinical Services

We treat people with Cognitive Behaviour Therapy (CBT) when their main problem is an anxiety disorder, especially Obsessive Compulsive Disorder (OCD), Body Dysmorphic Disorder (BDD), Post Traumatic Stress Disorder (PTSD), Social Anxiety Disorder (SAD), Panic Disorder (PD), Specific Phobias (eg driving, flying etc), Specific Phobia of Vomiting (SPOV or Emetophobia), General Anxiety Disorder (GAD) and Health Anxiety (HA).

Hoarding Disorder (HD)

Please note that we now only offer treatment to patients with hoarding problems living within our local catchment area of Lambeth, Southwark and Lewisham due to the time it takes to do home visits for the home-based work which is essential for the treatment to be successful.  For patients with a GP registered outside our area, the referrer may wish to refer to the patient’s local mental health team.

Our Clinic provides both a local and National Service which spans primary, secondary and tertiary care. We form a small part of each of SouthwarkLambeth and Lewisham  Talking Therapies Services (aka Improving Access to Psychological Therapies - IAPT) and also the Integrated Psychological Therapies Teams (IPTT) for Southwark, Lambeth and Lewisham.  We also accept written referrals nationally both from Community Mental Health Teams as well as GPs (please see below for referral pathways to our clinic).  In addition the clinic holds a Highly Specialised Service (HSS) contract with NHS England to provide treatment for people with OCD and/or BDD for whom numerous previous treatments have been unsuccessful.

CADAT-PAX: CADAT for Parents with AnXiety disorders

We accept written referrals.  Please complete the attached Referral Document online and email to us at our secure email address: Alternatively referrals can to posted to the Referrals Coordinator, The Centre for Anxiety Disorders & Trauma, 99 Denmark Hill, London SE5 8AZ.

The guidance below explains how to access a referral:     

If you live in Lambeth, Southwark and Lewisham

Talking Therapies (aka Improving Access to Psychological Therapies IAPT) Referrals

Most people when first referred for psychological therapy are directed to the Talking Therapies Services.  Referrals as based on the person's GP address and not the person's home address.

If the person has a GP that has a registered address within these Boroughs and they require treatment in primary care then they should be referred direct, in the first instance, to their local Lambeth, Southwark or Lewisham Talking Therapies Service (patients can also self-refer to Talking Therapies).  Please follow the links above depending on which Borough your GP is registered in.  Allocations are then made to CADAT from within the appropriate Talking Therapies Service. We regret that we are unable to accept direct GP referrals for patients who live within these Boroughs.

Integrated Psychological Therapies Teams (IPTT) Referrals 

People with more complex problems who require treatment within secondary care should be referred to their local Lambeth, Southwark or Lewisham IPTT service in the first instance. IPTT are specialist psychology therapy services that provide assessment, care and treatment for people aged 18-65 who have a severe mental illness and live in one of these Boroughs. Referrals are accepted from mental health professionals working with IAPT or Community Mental Health Teams (CMHTs).  Allocations are then made to CADAT from within the appropriate IPTT service.

Specialist Funding Panel Referrals

People who live in these Boroughs but are found to be too complex to be treated within the Talking Therapies Services or IPTT (as described above) and require tertiary care, can also be treated at our service.  Referrers must make an application to the appropriate Lambeth, Southwark or Lewisham Specialist Funding Panel for cost-per-case funding.  We regret that in these cases, we are unable to offer any appointments until funding has been authorised by the appropriate Specialist Funding Panel.

Referrals from other SLaM Services

We are unable to receive direct referrals from other SLaM Services for patients with a GP registered within Lambeth, Southwark or Lewisham.  Please follow the most appropriate referrals pathway above.

If you live in Croydon

The Croydon Clinical Commissioning Group (CCG) would like all Croydon residents to be seen locally in the first instance and will not automatically fund referrals to CADAT.  We would suggest that you refer within local Croydon services to one of the following:

Croydon Talking Therapies (aka Improving Access to Psychological Therapies IAPT).

Croydon Talking Therapies (Tel: 020 3228 4040 (Reception) or 020 3228 4038 (Referrals).  This service is for people who live within this Borough and  require treatment in primary care.  

Croydon Integrated Psychological Therapies Service (CIPTS) Referrals

People with more complex needs should be referred to CIPTS in the first instance.  The CIPTs Team will usually treat themselves.  However, in some instances, they may decide to refer to CADAT which does not require funding to be sought from the Croydon CCG

Referrals from other SLaM Services

We are unable to receive direct referrals from other SLaM Services for patients with a GP registered within Croydon.  Please follow the most appropriate referrals pathway above.

If you live OUTSIDE Lambeth, Southwark, Lewisham and Croydon

GP referrals and Patient Choice

GPs outside our local catchment area can refer direct to CADAT.  

The Government has introduced the legal right for patients and their GP to choose who provides their care, just as they can if patients are suffering a physical illness. Please visit the links below for more detailed information:

NHS Improvement-making choice in mental health work

NHS Improvement Choice in Mental Health: how it can work for you-April 2016 (opens in a pdf)

 Please note that certain conditions need to be met for us to be able to accept GP Patient Choice referrals to our clinic:

  • Our clinic only treats patients whose main presenting problem is an anxiety disorder of the type we treat e.g. Obsessive Compulsive, Hoarding, Body Dysmorphic, Post Traumatic Stress, Social Anxiety, Panic, Generalised Anxiety Disorders, or some Specific Phobias. One of these needs to be the primary presenting problem requiring treatment.
  • Your GP must have discussed referral options with you, and from amongst the options presented you must have decided that you would like to be seen by our service.
  • Your GP needs to refer you to our clinic under Patient Choice, and mentioning in their referral letter which anxiety disorder you are seeking help for.
  • You can’t be receiving any current treatment from elsewhere for the problem being referred
  • If you are struggling with other significant presenting problems which require treatment, we may not be able to see you under Choice, as you may need to receive treatment for these problems elsewhere in the first instance.
  • If you present with significant risk to yourself, we may recommend referral to our clinic via a different route e.g. we may suggest that you first be linked in to your local community mental health services, who may then decide to refer you on to our service as a national referral. This is usually done to ensure that patients are offered local and, where needed, crisis support which we are unable to offer. In these cases you will need the support of your Community Mental Health Team and the local Clinical Commissioning Group to be funded for treatment at our clinic.

What to do if you are struggling to be referred to our service under Patient Choice

If you believe that you meet the criteria for the above, but your GP or local services are not willing to refer you to our service, please read through the above document on Patient Choice, and consider printing off a copy of this article or the above website page for your GP if needed.  We are always happy to discuss referrals with clients and GPs as needed.  If a Patient Choice referral is refused,  you may wish to talk to an advocacy worker (for example OCD Action ( ) or OCD UK ( if you suffer from OCD or BDD), or to your local Patient Advice and Liaison Services (PALS).  Patients and GPs should also go to the health regulator, called NHS Improvement one of whose roles is to regulate Patient Choice.  NHS Improvement wants to know about cases where funding is refused for a clinically appropriate referral to an outpatient service offering a standard package of care.

However under some circumstances we cannot accept a referral from a GP and patients must be referred by to us by their local Community Mental Health Team (CMHT): if, for example, patients have significant risks (e.g.suicide) that require CMHT involvement or are likely to need integrated care with social services.

Talking Therapy Referrals (aka IAPT)

We can accept referrals for people who live outside of our local catchment area.  However, if the person requires treatment in primary care we would suggest that they be referred to their local Talking Therapies Service (patients can also self-refer to Talking Therapies in many cases) in the first instance.  Should the Talking  Therapies service decide that the patient now requires more specialist care they can refer to our service and we will seeking funding (see below).

Secondary Care/National Referrals 

For more complex difficulties Community Mental Health Teams (CMHTs) and other secondary care services can refer direct to our service and we will seek funding (see "Funding for all National Referrals" below).  Please Note:  these patients need to remain linked in with their local teams, so that they have continuity of local care, and can be assisted if in crisis or with other local assistance.

Funding for all National Referrals

If our team decides a national referral to our service is appropriate, we contact the patient’s local Clinical Commissioning Group Commissioner (CCG) and request funding authorisation for an assessment.  The CCG are responsible for authorising funding for out of area assessments and treatment and all requests for assessments and treatments of national patients have to go via them.  If the CCG agree to fund the assessment, we endeavour to offer an appointment within 11 weeks although this does depend on the caseloads of our therapists. Funding does have to be secured before we can offer an assessment or any subsequent treatment if appropriate.  

Referrals from other SLaM Services

We are unable to receive direct referrals from other SLaM Services for patients with a GP registered outside of our catchment area of Lambeth, Southwark or Lewisham.  Please follow the most appropriate referrals pathway above.

If you have severe OCD or BDD and have had multiple previous pharmacological and psychological treatments, live in England, and would like to be assessed and treated under our NHS England Highly Specialised Service (HSS)

CADAT has a contract with NHS England to provide treatment to people with severe OCD and/or BDD who have not made or maintained gains with two or more sets of previous psychological treatment and appropriate treatment with medication. If eligible these people are assessed and treated at no cost to the local CCG. This service is open to all of England including people who live in our local catchment area of Lambeth, Southwark, Lewisham and Croydon.  Please Note: Patients must remain linked in with local teams so that we can provide a joint approach with them, especially for times of crisis.

We accept written referrals addressed to The Referrals Coordinator, The Centre for Anxiety Disorders & Trauma, 99 Denmark Hill, London SE5 8AZ.  These can either be posted to the above address, or emailed to us via our secure email address:

For any queries on HSS referrals to CADAT please email Tracey Taylor.

If you wish to be seen privately

We are an exclusively NHS clinic and do not offer assessment or treatment on a private basis.  However referrers who would like their patients to be seen at our service via the NHS, may wish to exercise Patient Choice. Please see above for more information.
