Car Seats for children
Using a child car seat or booster seat
Children must normally use a child car seat until they’re 12 years old or 135cm tall, whichever comes first.
Only EU-approved child car seats can be used in the UK. These have a label showing a capital ‘E’ in a circle.
You can choose a child car seat based on your child’s height or weight.
Height-based car seats
Height-based car seats are known as ‘i-Size’ seats. They must be rear-facing until your child is over 15 months old. Your child can use a forward-facing car seat when they’re over 15 months old.
You must check the seat to make sure it’s suitable for the height of your child.
Weight-based car seats
The seat your child can use (and the way they must be restrained in it) depends on their weight.
You may be able to choose from more than one type of seat.
