The Care Act 2014 is a piece of legislation in the United Kingdom that sets out the legal framework for the provision of social care and support to adults in England. The act aimed to simplify and modernise the existing legal framework for adult social care, and to make it easier for people to access the care and support they need.

The Care Act 2014 introduced a number of key changes to the way social care is provided in England, including:

1. A new definition of what constitutes 'care and support', which includes support for carers as well as for the person being cared for.

2. A strengthened duty on local authorities to assess and meet the needs of carers, as well as the people they care for.

3. The introduction of a single assessment process for all people who need care and support, which aims to make it easier for people to access the help they need.

4. A new eligibility criteria for social care, which sets out the minimum level of need required to qualify for support.

5. A new system of charging for social care, which aims to make it fairer and more transparent.

6. The introduction of a right to control the support received, which gives people greater control over the care they receive and how it is provided.

7. A strengthened role for the Care Quality Commission in regulating and inspecting care services.

The Care Act 2014 applies to England only. Similar legislation applies in Scotland, Wales, and Northern Ireland.
