People Receiving Care Who Lack Mental Capacity to Take Decisions: Implementation of the Mental Capacity Act 2005 in Domiciliary Support (Wales) Policy


The Mental Capacity Act (MCA) was introduced into England and Wales in April 2007 to provide a statutory framework to protect those who lack the mental capacity to make their own decisions, such as those with severe dementia or any other significant brain dysfunction, and those who are dying and no longer capable of making decisions for themselves.

The Act applies to people aged 16 years and over and sets out:

Certain groups of people are legally required to have regard to the Act and its associated Code of Practice when making decisions on behalf of people who lack mental capacity. This includes doctors, nurses, health and social care managers and staff.

Wales Standards Compliance

The service must comply with the Regulated Services (Service Providers and Responsible Individuals) Regulations 2017 in its approach to mental capacity issues. It takes particular note of the following regulations:

Policy Statement

{{org_field_name}} complies with the principles of the Mental Capacity Act 2005, which applies to England and Wales, by first treating everyone who uses its service or is applying to become a user, on the basis that they are able to take their own decisions and give valid consent to their care and treatment.

Consistent with the legislation, {{org_field_name}} is prepared to take a decision for a person in their best interests if there is evidence that they cannot take the decision (at the time it needs to be made) because of mental incapacity.

It is recognised that decisions under the Act include those to be made about matters of personal health, such as consent to medical intervention, care, general welfare and finance.

Definition of Capacity

{{org_field_name}} understands that the ‚Äúcapacity‚ÄĚ referred to in the MCA refers to the mental capacity to make a decision. Where a person is described as ‚Äúlacking capacity‚ÄĚ this means that the person is judged as being unable to make a decision for themselves because of an impairment of (or a disturbance in the functioning of) the mind or brain, whether temporary or permanent.

{{org_field_name}} also understands that ‚Äúcapacity‚ÄĚ can change and may relate to different decisions differently. Therefore, a lack of capacity should never be assumed or presumed.

Principles and Aims

{{org_field_name}} supports the principles of the Mental Capacity Act as follows.

  1. Individuals must be assumed to have capacity unless it is established that they lack capacity.
  2. Individuals are not to be treated as unable to take a decision unless all practicable steps have been taken without success to help them to take the decision.
  3. Individuals must not be treated as unable to take a decision just because they might or have been known to make an unwise decision.
  4. When people take a decision on behalf of someone else who lacks capacity, they must act in that person’s best interests.
  5. If anyone takes a decision on behalf of someone lacking capacity at the time, they must act to minimise any restriction of that person’s rights and freedom of expression and movement.


The service implements these principles in the following ways.

  1. The service treats all current and prospective people receiving its care on the basis that they take their own decisions. This is confirmed in the individual plan of care.
  2. Where the service has information that suggests the person might be unable to take some decisions at some of the time, it will carry out an assessment of that person’s mental capacity. The assessment follows the two-step assessment process recommended in the MCA’s Code of Practice.
  3. The service knows about and acts on any advance directives or ‚Äúliving wills‚ÄĚ that people receiving its care have chosen to make in contingency situations where they might lose the ability to take a decision. Where appropriate, the service also encourages people to make end-of-life plans so that their wishes are known in the event of their death.
  4. The service ensures that it responds correctly where people receiving its care are subject to guardianship proceedings or who have agreed that others should decide admission on their behalf such as an LPA for personal welfare.
  5. The evidence and methods used to make the assessment and the outcomes are recorded on the person’s needs assessment and plan of care respectively. The information indicates:
    a. which decisions the person can take at all/most times
    b. those that the person has difficulty in taking
    c. those that the person is unable to take.
  6. In respect of each area of decision-taking where there are difficulties or an inability to take decisions, the individual plan of care records the actions to be taken for the person that are deemed in their best interests.
  7. {{org_field_name}} ensures that the individual is always as fully involved as possible. It will only take decisions with full information available and the agreement of those concerned in the person’s care and future. All decisions taken for that person are fully recorded and made subject to regular review.
  8. The service has a separate policy on restraint. People receiving care who lack mental capacity as any others, are only subject to any form of restraint when not doing so, would result in injury or harm to them or to other people. All incidents where restraint has been used following the home’s procedures for reporting and recording.
  9. The service has access to independent advocates (IMCAs) and other professionals who can assist in the assessment and who understand the implications for that person’s care.
  10. The service is aware of the importance of protecting people’s rights and freedom, and will always work to make sure that no person who might lack capacity is unlawfully deprived of their liberty. (See separate policy on Human Rights and Deprivation of Liberty.)
    a) If the person receiving care, in this position, is in a care home, the care home will seek to safeguard the person’s interests by applying for authorisation under the deprivation of liberty safeguards’ protocols.
    b) The service understands that the deprivation of liberty safeguards do not apply at present to people living in their own homes, including under tenancy agreements and supported living arrangements. If it is evident to the responsible care service that any such person is suffering loss of liberty because of the controls and restrictions placed on them, it will refer the matter to the local adults’ safeguarding authority for action, which could result in applications to the Court of Protection to apply any safeguards necessary.
  11. {{org_field_name}} will only take a decision for one of the people receiving its care after it has exhausted every means of enabling them to take it of their own accord. It will also show its actions in taking the decision are reasonable and are in the person’s best interests.
  12. It will always work closely with anyone with powers of attorney for an individual to determine the best interests of the cared for person, and with any representatives appointed by the Court of Protection.

Staff Involvement

  1. The service expects its care (and nursing) staff to implement the agreements and decisions that are identified on an individual’s plan of care.
  2. The service also expects its staff to involve people receiving its care in all day-to-day decisions that need to be taken by seeking their consent and checking that the actions to be taken are consistent with their plan of care if the person lacks capacity at the time.
  3. Where the person’s need to take a decision that lies outside of their ability at the time, staff must do everything to help them decide for themselves.
  4. The service expects its staff to avoid taking decisions on behalf of a person receiving care unless they can show that it is necessary and the person is at the time unable to take that decision themselves. Any such incident must be fully recorded.
  5. The service expects its staff to take decisions for people receiving care lacking capacity only because they have reasonable beliefs that they are necessary and in the person’s best interests. When in doubt that they can proceed in this way they must seek advice from their line manager.


The service provides staff training on all aspects of mental capacity to improve their knowledge and develop skills in working with people receiving its care over their decision-making abilities.

{{org_field_name}} provides induction training for new staff in line with the All Wales Induction Framework for Health and Social Care.
