Quick answer
In the UK, children must normally use a car seat until they are 12 or 135cm tall, whichever comes first. Rules for taxis and private hire cars can differ, so do not assume a seat will be there. Request baby seats and boosters when you book, and give each child age and height.
What are the UK child car seat rules?
GOV.UK says children must normally use a child car seat until they are 12 years old or 135 centimetres tall, whichever comes first. After that they must wear a seat belt. Only approved seats can be used in the UK, marked with an "E" in a circle and either "R129" (height-based) or "ECE R44" (weight-based). Height-based seats must be rear-facing until the child is over 15 months old, and a child seat must not be fitted in a side-facing seat.
| Child | General rule (GOV.UK) | What to do for your transfer |
|---|---|---|
| Baby | Approved rear-facing seat | Request an infant seat at booking |
| Toddler | Approved child seat for their height or weight | Give age and height so the right seat is fitted |
| Older child under 135cm and under 12 | Child seat or booster | Request a booster at booking |
| 12 or over, or taller than 135cm | Seat belt | No seat needed |
Read the full guidance at GOV.UK: child car seats, the rules. The rules for licensed taxis and private hire vehicles are set out separately, so check the current wording rather than relying on a summary.
How do I request a baby seat with my airport transfer?
- Ask when you book. Tell the operator the age and height of each child so the correct seat is fitted. See our baby seats page.
- Confirm it in writing. Your booking confirmation should mention the seat. If it does not, contact the team before you travel.
- Bring your own if you prefer. Some families use their own approved seat for a familiar fit - tell the driver so they allow time to install it.
Which vehicle suits a family with luggage?
Children bring more luggage and more seats, so count both before choosing. A saloon fits most small families, but a car seat takes space. For three or more children or a lot of cases, choose a larger vehicle and tell the operator how many seats and bags you have. For long-haul arrivals, our arrival guide for US visitors covers the steps from landing to pickup.
Is a private transfer easier than public transport with children?
For most families, yes. One vehicle takes you from the terminal to your door without stairs, platforms or a second journey. Compare the options for your airport: Heathrow, Gatwick or Luton. For a price, use the instant quote form.
