Mental Capacity Assessments: Are Care Providers Passing Their Responsibilities to Social Workers?
Understanding who is responsible in domiciliary care, supported living and residential care.
Who Is Actually Responsible?
At Team Care Compliance, we regularly support providers and Registered Managers to strengthen safeguarding and governance. One recurring misunderstanding is that mental capacity assessments are always the responsibility of social workers, GPs or local authorities. That is not the case.
Responsibility depends on the decision being made and the professional proposing or carrying out the action.
The Five Principles of the Mental Capacity Act 2005
The Act:
- Presumes capacity unless established otherwise.
- Requires practicable support to make decisions.
- Protects the right to make unwise decisions.
- Requires decisions made for a person lacking capacity to be in their best interests.
- Requires consideration of less restrictive alternatives.
Capacity is decision-specific and time-specific. A diagnosis alone does not establish a lack of capacity.
Can Care Workers Conduct Capacity Assessments?
Yes, where appropriate to their role and competence. The Mental Capacity Act Code of Practice explains that the assessor is usually the person directly concerned with the individual when a decision needs to be made.
For example, a care worker may need to assess capacity to consent to a particular routine personal-care intervention where there is reason to doubt capacity. The treating clinician normally assesses consent to their proposed treatment. Major accommodation decisions may be led by social workers or other responsible decision-makers. Complex or disputed cases may need specialist assessment or legal advice.
The Provider and Registered Manager Responsibilities
Under CQC Regulation 11 (Need for Consent), providers must ensure care is delivered with appropriate consent and, where someone lacks capacity, in accordance with the Mental Capacity Act.
Managers must ensure staff are trained and competent, concerns are identified, assessments and best-interest decisions are appropriately recorded, and restrictions and escalation routes are governed effectively. The manager need not personally conduct every assessment.
“We Are Waiting for the Social Worker”
Involving a social worker can be essential for complex accommodation, safeguarding or multidisciplinary decisions. But waiting for an external professional is not a blanket substitute for applying the MCA to routine care.
Staff should support the person to decide, assess capacity where there is a genuine reason to doubt it and seek specialist input where necessary. Care providers cannot delegate away their own responsibilities.
An Assessment Is More Than a Form
A valid assessment considers whether there is an impairment or disturbance in the functioning of the mind or brain and whether that causes the person to be unable to make the specific decision when required.
The functional test considers:
- Understanding relevant information.
- Retaining relevant information.
- Using or weighing relevant information.
- Communicating a decision by any means.
Record the support offered, the reasoning and the outcome. Avoid blanket statements such as ‘lacks capacity for all decisions’.
Best Interests and Restrictive Practice
Where someone lacks capacity for a specific decision, the appropriate decision-maker must follow the best-interests process, considering the person’s wishes, values, relevant circumstances and views of appropriate consultees.
An MCA assessment or best-interests record does not itself authorise a deprivation of liberty. Care homes and hospitals may require DoLS authorisation where applicable; supported living and domiciliary care settings may require Court of Protection authorisation.
What Should Managers Audit?
Look beyond whether an MCA form exists. Review:
- Decision specificity.
- Support to decide.
- Assessment reasoning.
- Best-interests consultation.
- Restrictions and legal authorisations.
- Staff competence.
- Involvement of external professionals.
- Review arrangements.
Not everyone needs a formal capacity assessment: capacity must be presumed unless there is reason to doubt it for a particular decision.
How Team Care Compliance Can Help
Our team supports care providers with MCA and consent audits, safeguarding and restrictive-practice reviews, assessment-quality checks, governance improvements, Registered Manager mentoring, CQC Regulation 11 reviews and mock inspections.
Our focus is on lawful decisions, meaningful evidence and protecting people’s rights.
The Message for Care Providers
The question should not be simply ‘Who can we send this assessment to?’ It should be: ‘Are we fulfilling our responsibilities, and do our staff have the competence and support to make lawful decisions?’
External professionals have essential roles, but care providers cannot automatically transfer their own responsibilities to them.
