Carer's Leave Certificate - Caring Responsibilities Documentation
Requesting reasonable adjustments at work, in education, or in housing often requires a signed letter from a registered UK GP confirming your condition and the accommodations you need. Our online service lets you obtain that documentation without the wait for a face-to-face appointment.
Each disability accommodation letter is issued following an individual clinical assessment by a licensed UK doctor, giving employers, institutions, and housing providers the evidence-based medical documentation required to act on your request.

A carer’s leave certificate is a medical letter confirming that a person in your care has a long-term condition, disability, or care need — supporting your request for statutory carer’s leave under the Carer’s Leave Act 2023. While the law does not require employees to provide medical evidence, many employers ask for supporting documentation voluntarily. This guide explains the legislation, when a medical letter may help, and how to obtain one quickly online, subject to clinical review.
The Carer’s Leave Act 2023 came into force on 6 April 2024, giving employees in England, Wales, and Scotland a new day-one right to up to one week’s unpaid leave per year to care for a dependant with a long-term care need. Understanding how the law works — and when medical documentation adds value — can help carers navigate workplace conversations with confidence.
What the Carer’s Leave Act 2023 Says About Medical Evidence
Key points from the Carer’s Leave Act 2023 and the Carer’s Leave Regulations 2024
- Employees are entitled to up to one week of unpaid carer’s leave per 12-month rolling period
- The right applies from the first day of employment — there is no minimum service requirement
- Leave can be taken in half or full days, flexibly or as a full week block
- Employers cannot require employees to provide evidence of their caring responsibilities before granting leave
- Employees must give notice — either three days or twice the length of leave requested, whichever is longer
- Employers can postpone (but cannot refuse) leave if it would cause serious operational disruption, within a one-month window
- Employees are protected from dismissal or detriment related to taking carer’s leave
Legally, you do not have to provide a medical certificate or any other evidence to take carer’s leave. You self-certify by notifying your employer that you meet the eligibility criteria. However, some employers — particularly in larger organisations with formal HR processes — may encourage supporting documentation as part of their internal carer’s leave policy, or you may wish to provide it proactively to strengthen your position.
Who Qualifies for Carer’s Leave?
To be eligible for statutory carer’s leave, the person you are caring for must meet two criteria: they must be your dependant, and they must have a long-term care need.
Eligible Dependants
- Spouse or civil partner
- Child (no age limit specified)
- Parent
- A person living in the same household (not as a boarder, employee, lodger, or tenant)
- Any person who reasonably relies on you for care
Qualifying Conditions
- An illness or injury (physical or mental) requiring care for more than three months
- A disability as defined under the Equality Act 2010
- Care needs arising from old age
When a Carer’s Leave Medical Letter Can Help
Although the law does not require medical evidence, there are several situations where a doctor’s letter confirming the care recipient’s condition can be valuable:
Opening a Workplace Conversation
A medical letter confirming your dependant’s condition can facilitate a more productive conversation with HR or line management about your caring responsibilities and any flexible working arrangements you may want to request alongside carer’s leave.
Employer’s Internal Policy
Some employers have their own voluntary documentation processes for carer’s leave — for example, asking carers to complete a self-certification form. A supporting medical letter can complement this if you choose to share it.
Extended Leave Requests
The statutory entitlement is one week per year. If you need more time — for example, through a flexible working request or an informal arrangement — medical documentation supporting the nature of the condition can strengthen your case.
What a Carer’s Leave Medical Letter Contains
A medical letter in support of a carer’s leave request typically confirms information about the person being cared for, rather than the carer themselves. A MedicalCert carer’s leave letter, subject to clinical review, will confirm:
- The nature of the condition or care need (at the appropriate level of clinical detail)
- That the condition is long-term, chronic, or ongoing in nature
- That the person requires regular care, assistance, or supervision
- The date of assessment and the reviewing doctor’s GMC details
- A unique reference number for verification
The letter is addressed to the employer (or “To Whom It May Concern”) and is written in clear, professional language appropriate for an HR context. It does not disclose unnecessary clinical detail — only what is relevant to confirm eligibility for the leave.
How to Get a Carer’s Leave Medical Letter Online

Does my employer have to accept my carer’s leave request?
Yes. Under the Carer’s Leave Act 2023, employers cannot refuse a carer’s leave request outright. They can postpone it if your absence would cause serious operational disruption — but they must agree an alternative date within one month and provide written reasons within seven days. Dismissing an employee for requesting or taking carer’s leave is automatically unfair dismissal under UK employment law.
Do I have to tell my employer what condition my dependant has?
No. The law specifically states that employers cannot require evidence of your caring responsibilities. You are only required to confirm that you are eligible — i.e., that you have a dependant with a long-term care need. You are not required to disclose the specific diagnosis or personal details of the person you care for.
Can I take carer’s leave for more than one person?
Yes, but the maximum remains one week per year regardless of the number of dependants you care for. You can use your week’s entitlement across care for more than one person — for example, three days caring for a parent and two days for a child with a disability.
Is carer’s leave paid?
The statutory entitlement is unpaid. However, some employers choose to offer paid carer’s leave as part of their employment package. Check your employment contract or HR handbook to see whether your employer offers enhanced carer’s leave terms.
What if my employer refuses my carer’s leave request entirely?
An employer cannot refuse carer’s leave — they can only postpone it within the rules. If your employer refuses outright, this may constitute a breach of your statutory rights. You should consider raising a formal grievance and, if unresolved, can make a claim to an employment tribunal. Citizens Advice and Carers UK both provide guidance on employment rights for carers.
Can carer’s leave be used for medical appointments?
Yes. Carer’s leave can be used for a range of caring activities, including accompanying a dependant to a medical appointment, providing personal care, arranging care services, or supporting someone with practical or official matters. The law does not restrict the definition of “providing or arranging care” to any particular activity type.
