CO postcodes
Autism & ADHD Support in Colchester (CO)
Our Colchester appointment venue, The Chill Out Centre, sits inside the CO postcode area, so families across Colchester, Tendring and the Mersea and Wivenhoe villages have the shortest journey to it of anywhere in Essex.
Living in the CO postcode area
The CO postcode area covers Colchester and much of north east Essex, including Wivenhoe, Tiptree, West Mersea, Brightlingsea, Clacton-on-Sea, Frinton, Harwich and Manningtree. Families here live within Essex County Council, so SEN Support, EHC needs assessments and local services are described in the Essex Local Offer.
Because our Colchester appointment venue, The Chill Out Centre, sits inside the CO area, families here often choose in-person stages such as an ADOS-2 observation or a face-to-face dyslexia assessment. Consultations and feedback can still be online if that is easier around school and work.
Assessments are also available online for adults and families anywhere in the UK, so a move out of the area does not mean starting again. Our reports are written with Essex SEND processes in mind, using language schools and the local authority recognise when provision is being considered.
Not sure where to start? You can begin with a free online screener, or book a consultation and we will talk through the options for your family, with no obligation.
