Child Behaviour Support at home and in school

Our approach is grounded in the transformative science of Applied Behaviour Analysis (ABA), but we don't stop there.

We weave in our values-based philosophy and trauma-informed practices to provide the utmost care and emotional support to children, teens, and young adults.


ABA therapy for Autism & Special Needs: Child & Young Adult Behaviour Support


Our UK team of ABA therapists and Behaviour Specialists train and educate parents, families, schools, local authorities, and caregivers on the necessary skills to allow Autistic children and SEN young adults to thrive.

At All Behaviour Consultancy, we do things a little differently.

Leading first and foremost with compassion, we help Autistic children and young adults with other special needs navigate a neuro-typical world.

Our company is built on the belief that everyone deserves a place of belonging, where their safety and comfort is upheld, and their voices are not only heard but valued and respected.

We wholeheartedly commit ourselves to creating and nurturing a safe environment where every individual can flourish.

Our mission is to empower parents and schools to embrace their roles with confidence, whilst providing the tools and knowledge needed to champion their child's journey to success.


Autism Therapy in London + Online

Using the science of Applied Behaviour Analysis (ABA), we create a supportive atmosphere for Autistic children whilst we tackle their unique challenges.

The goal is for each individual to feel confident in a neuro-typical world, improving resilience, understanding, and positive growth.

We assess child behaviour in real-life situations and incorporate ABA techniques to help manage challenging behaviour, using Positive Behaviour Support.

Our person-centred approach is built around each individual's needs, empowering them to flourish while enhancing essential skills, including communication, personal care, and social interactions.

We offer ABA consulting online for the rest of the UK and provide ABA therapy for schools in London and families at home.


As Child Behaviour Specialists in London, we pride ourselves on our uplifting and empathetic therapeutic approach, which is based on Positive Behaviour Support strategies.

Navigating social, emotional, and behavioural challenges can feel daunting, so we design a calm, safe, and thriving environment for growth.

Our approach is tailored to meet each child or young adult’s unique needs and situation and our values are the foundations of how we operate as a company aimed at changing people’s lives.

What to expect with an ABA Therapist

Our three-step ABA Therapist service:

  1. Initial visit - This involves meeting the child in their current environment (home or school), speaking briefly to those who know the pupil best, understanding what the challenges are, observing the pupil’s level of interaction and looking at their level of academic attainment.

  2. Detailed Functional Assessments - This is undertaken by a Certified Behaviour Analyst – a combination of observations, interviews and data collection to ensure that we put positive interventions in place that match the functions behind the behaviour.

  3. Empowering Parents and Staff – We provide parents and school staff with individualised training and ongoing consultancy support. This is key for ensuring desired and lasting positive change.


Our impact doesn't end with the individuals we serve.

We are dedicated to uplifting the entire household.

We empower parents and siblings of our neurodivergent and/or disabled clients with a shared commitment to enhancing the overall quality of life for everyone.
