Stricter laws about what type of car seat you can use are set to come into force in Chester and the UK later this year , and it could be quite an expensive change.

At the moment, cheaper and backless booster seats are approved for children weighing 15kg (about three-years-old), but when the new regulations come in, children will have to be taller than 125cm and weigh more than 22kg to use them.

But according to child car seat experts, this type of booster seat is unsuitable for such young children.

A small child isn't held as securely in the seat, the adult seat belt isn't guided across their small body in the best way, and most importantly, a booster seat offers no protection for a child if your car is involved in a side-impact crash.

The high-backed seat which are more expensive, have been found to be safer.

So before the law comes into effect in December we have had a look round at some of the best deals on the market right now.

Child car seat laws

  • UK law states that children must use a child car seat until they're 12 years old or 135cm/4ft 5in tall, whichever comes first.
  • Safety experts recommend that you use a child car seat for all children under 150cm/4ft 11in. This height is the legal requirement in Ireland and also some European countries, such as Germany and France.
  • Children under three must be in a child car seat. If there’s no room for a third child seat in the back of your vehicle. Children aged three or under can use the front seat but they must be in a child car seat.
  • You can’t take children under three on an unexpected journey in a vehicle without a seat belt or the correct child car seat. The only exception to this rule is if it's in a licensed taxi or minicab and the rear seats are separated from the driver by a fixed partition and the child travels on the rear seats.
  • If you ignore the law you are liable to a find of £500 if you go to court.

The new rules come in this December but will only apply to any new products appearing on the market. So parents looking to buy a booster seat next year should start to see that they're not approved for use with children under 125cm and 22kg. Parents who have a booster seat now will still be able to use the seat without breaking any rules.
