A local authority may revise a care and support plan; and in deciding whether or how to do so, it—
must have regard in particular to the matters referred to in section 9(4) (and specified in the plan under section 25(1)(d)), and
must involve—
the adult to whom the plan relates,
any carer that the adult has, and
any person whom the adult asks the authority to involve or, where the adult lacks capacity to ask the authority to do that, any person who appears to the authority to be interested in the adult's welfare.
A local authority may revise a support plan; and in deciding whether or how to do so, it—
must have regard in particular to the matters referred to in section 10(5) and (6) (and specified in the plan under section 25(1)(d)), and
must involve—
the carer to whom the plan relates,
the adult needing care, if the carer asks the authority to do so, and
any other person whom the carer asks the authority to involve.
Where a local authority is satisfied that circumstances have changed in a way that affects a care and support plan or a support plan, the authority must—
to the extent it thinks appropriate, carry out a needs or carer's assessment, carry out a financial assessment and make a determination under section 13(1), and
revise the care and support plan or support plan accordingly.
Where, in a case within subsection (4), the local authority is proposing to change how it meets the needs in question, it must, in performing the duty under subsection (2)(b)(i) or (3)(b)(i), take all reasonable steps to reach agreement with the adult concerned about how it should meet those needs.
