Dimensions UK is a British not-for-profit charitable registered society and housing association that supports people with learning disabilities, autism and complex needs.

[4] Following research with the University of Kent's Tizard Centre,[5] Dimensions introduced a new model of supporting people with learning disabilities and autism in 2015, known as Activate.

[8] Waymarks, a charity that helps people with learning disabilities or autism who have forensic histories or risky behaviours to change their lives, was created in 2009 and fully merged into Dimensions Group in 2019.

[9] In 2017 Discovery was launched in partnership with Somerset County Council to provide support for adults with learning disabilities in the region.

[25] Dimensions has also produced 'autism-friendly' resources and training for libraries (as with the cinema screenings, these changes are aimed at autistic children and their families).
