My name is Rod from Golden Lane Housing and I am answering questions this month as the “housing expert”. Its good question and one I must admit I had to think about.
My understanding is domiciliary care is a term often used to describe home care which can be provided to anyone with care needs in their own home. Most people will be familiar with this as a description of care an older person might receive say from someone for a few hours each day but it applies generally to all care provided to anyone in the home.
A supported living service is a more specific name given to a model where accommodation, which is often rented from a housing association or local authority, is provided with care and support for the tenant. An organisation that provides care and support which could be in a supported living model is required to be registered as a domiciliary care provider with the Care Quality Commission.
I hope this explanation helps
