Noor Says NoWhat age can a child stay home alone?
Sources reviewed on November 1, 2026. Based on public advice, see below.
There is usually no single legal age, and a child of 4 to 7 is too young. Nemours KidsHealth says it is generally not a good idea to leave kids younger than 10 home alone. In the UK, the law sets no age, but it is an offense to leave a child alone if that puts them at risk.
What does the law say?
- United States: KidsHealth notes that some states have a minimum age. Check the rule where you live.
- United Kingdom: GOV.UK says the law does not name an age. Parents can be prosecuted if leaving a child alone puts the child at risk.
What do pediatric and child-safety sources advise?
KidsHealth says that at under 10, most kids don't have the maturity and skills to respond to an emergency alone. GOV.UK passes on the NSPCC's guidance: babies, toddlers and very young children should never be left alone, and children under 12 are rarely mature enough to be left for long periods.
What can you already teach at 4 to 7?
A few habits that help later, while you are home.
- The door rule. NCMEC suggests this pretend game for older kids who stay home alone: someone comes to the door with a delivery. The right answer is not to open up. Practice the younger version: no grown-up with you at the door, no opening it.
- Knowing details. NCMEC says children should know their full name, home address and phone number.
- Knowing when to call for help. Read how to teach your child to call 911 or 999.
How do you know a child is ready later on?
KidsHealth suggests looking at responsibility and judgment, and how your child handles the unexpected. Then do a practice run of 30 minutes to an hour while you stay close by and reachable, and talk about it afterward.
Frequently asked questions
Can I run a quick errand while my 6-year-old sleeps?
KidsHealth advises against leaving children under 10 home alone, because most can't respond to an emergency. Check your local law too. A sleeping child can still wake up.
What does the NSPCC say?
We could not open the NSPCC's own site, which refused automated requests. GOV.UK quotes its advice: children under 12 are rarely mature enough to be left alone for long periods.
