NSPCC advises against leaving children under 12 years old unsupervised for long periods of time in the UK. Parents should consider each child's maturity, understanding, and ability to handle emergencies before leaving them alone. There is no legal age to leave a child alone, but it is against the law if it puts them at risk. NSPCC offers advice and tips to help parents ensure their child is ready when making the step.
