All the services Islington fund to help people live at home have a cost. These costs are met through a combination of government grants, council tax and by the money people pay to receive these services.
Islington Council wants to help as many people as it can to live at home independently and as safely as possible. They also want the charges for the care and support that they provide to be fair and affordable. Therefore everyone applying for, or receiving, a service will be assessed under their contributions policy. See here
