How to take carer's leave comes down to three numbers. One week a year, a minimum of half a day at a time, and notice of at least twice the length of the leave. Everything else, the forms, the proof, the fear of a refusal, is simpler than most working carers expect. GOV.UK and Acas say you need not ask in writing, you need no evidence, and an employer cannot refuse. This guide is the practical companion to the right itself, for anyone in Hertfordshire who works and cares.
We see the same thing from the care side. A daughter in Harpenden takes annual leave to sit with her father at the Lister, or rings in sick to cover a discharge. Nobody has ever told her there is a specific leave for exactly this. Our guide to carer's leave and working while caring explains the right and what may change. This one is about using it.
The rules below come from GOV.UK and Acas, read on 23 September 2026. They apply to employees in England, Scotland and Wales under the Carer's Leave Act 2023, in force since 6 April 2024.
How to take carer's leave, step one: check the person counts as a dependant
The leave is for giving or arranging care for a dependant with a long-term care need. Acas lists who counts. A husband, wife, civil partner or partner, a child, a parent, or someone who lives in your household other than a tenant or lodger. Also anyone who relies on you for care, including an elderly neighbour. GOV.UK is explicit that the person does not have to be a family member.
A long-term care need means one of three things. A disability under the Equality Act 2010, an illness or injury likely to need care for more than three months, or a care need related to old age. A parent with dementia fits. So does a spouse recovering from a stroke, or a mother in her eighties who is simply becoming frailer. You do not have to prove any of it.
How to take carer's leave, step two: work out how much you have
You get one week in any twelve-month period, and a week means the time you usually work over seven days. Someone on three days a week gets three days. It is one week in total however many people you care for. However, you can spread it across more than one dependant.
If your hours vary, GOV.UK's method is to add up the hours worked in the previous twelve months and divide by 52. If you have worked less than a year, divide by the number of weeks worked. Acas gives the worked examples. 780 hours over a year gives 15 hours of leave, and 180 hours over six weeks gives 30. In your first week of a job, use the hours you expect to work.
The right applies from the first day of employment. There is no qualifying period.
Step three: how to take carer's leave with the right notice
This is the part that makes carer's leave useful rather than theoretical. You can take the week whole, or as individual days, or as half days, spread across the year. The minimum unit is half a day. So a hospital appointment on a Tuesday afternoon can come out of the week. So can a discharge on a Friday morning and a care needs assessment the following month.
The notice rule is simple. For a half day or a single day, give at least three days' notice. For anything longer, give notice of at least twice the leave you want, in full days. Acas sets it out. Two days of leave needs four days' notice, three days needs six, and a full five-day week needs ten. The request does not need to be in writing. In our experience, though, an email makes the date easier to evidence later.
If the need is sudden and you cannot give that notice, carer's leave is the wrong tool. The right one is time off for dependants, which GOV.UK says is available without notice for emergencies. Many working carers use both across a year. Time off for dependants covers the day of the fall, and carer's leave covers the appointments that follow.
Step four: know what your employer can and cannot do
An employer cannot refuse carer's leave. What they can do is ask you to take it at a different time, and only where the absence would cause serious disruption. If they do, GOV.UK says they must agree a new date within a month of the one you asked for. They must also tell you the reason and the new date in writing, within seven days of your request and before the leave was due to start.
The leave is unpaid by default. Acas notes an employer may choose to pay it, so it is worth reading your contract or policy, or simply asking. Your other rights continue while you are away. You return to the same job on the same terms, and holiday and benefits keep accruing.
Acas is also clear that it is unlawful to dismiss someone, or treat them badly, for taking or asking for carer's leave. It lists what bad treatment looks like: missing out on promotion, a refusal of training, or a cut in hours without good reason. A dismissal for that reason could be automatically unfair.
Making the week go further
One week a year is not much against a parent's decline. That is why the week works best as a bridge to something that lasts. Families we support often use their carer's leave for the three or four days that matter most. The discharge, the assessment visit, the first day a carer comes to the house. Then regular care at home carries the weeks in between. A carer's assessment from the county council, which is free, is the other thing worth using the leave for. It puts on record what you are doing.
Starling Homecare is an independent, family-run provider regulated by the Care Quality Commission. Much of our work across Hertfordshire is with families where the caring relative also works full time. Our respite care page explains how we arrange regular cover, and our guide to respite care across Hertfordshire sets out the options town by town.
Common questions about how to take carer's leave
Do I need a letter from the GP to take carer's leave?
No. GOV.UK states that you need no evidence of the dependant's care needs, and Acas says the request does not need to be in writing. You simply ask, with the right notice, and confirm who you are caring for if your employer asks.
Can my employer say no to carer's leave?
No. An employer cannot refuse it. They can ask you to take it at another time only where your absence would cause serious disruption. Then they must agree a new date within a month, and explain the reason and the new date in writing within seven days of your request.
How to take carer's leave in half days: is it allowed?
Yes. Acas confirms the minimum unit is half a day. GOV.UK says you can take the week whole, as individual days, or as half days across the twelve months. A half day or a single day needs at least three days' notice.
Carer's leave is a small right that is easy to use once you know the three numbers. If you are in Hertfordshire and the caring is starting to outgrow a week, our St Albans office is on 01727 324 127.
