Regulations for Choosing Child Seats

banner-4

It is mandatory to use a child's car seat until they are 12 years old or 135 centimetres tall. You need to choose a child seat based on either the height or weight of the child.

  1. Height-based seats: Height-based baby seats are usually rear-facing for children under 15 months, and you can opt for a forward-facing seat only when they are over 15 months old. These seats are termed ‘i-Size’ seats. When buying a height-based baby seat, make sure the label shows a capital ‘E’ placed in a circle with ‘R129’ printed as a sign of EU approval. 

  2. Weight-based seats: The baby seat you choose and how you can restrain it will depend on the baby's weight. Only EU-approved weight-based baby seats are recommended. Look for the label showing the capital ‘E’ in a circle with ‘ECE R44’ printed. 

Here is a chart to help you understand the type(s) of seats to buy for your child depending on their body weight:

Finance Disclosure

Startin Group Ltd and Thomas Startin Junr Ltd are Appointed Representatives of Automotive Compliance Ltd, who is authorised and regulated by the Financial Conduct Authority (FCA No 497010). Automotive Compliance Ltd's permissions as a Principal Firm allows Startin Group Ltd, Thomas Startin Junr Ltd to act as a credit broker, not as a lender, for the introduction to a limited number of lenders and to act as an agent on behalf of the insurer for insurance distribution activities only.

We can introduce you to a selected panel of lenders, which includes manufacturer lenders linked directly to the franchises that we represent. An introduction to a lender does not amount to independent financial advice and we act as their agent for this introduction. Our approach is to introduce you first to the manufacturer lender linked directly to the particular franchise you are purchasing your vehicle from, who are usually able to offer the best available package for you, taking into account both interest rates and other contributions. If they are unable to make you an offer of finance, we then seek to introduce you to whichever of the other lenders on our panel is able to make the next best offer of finance for you. Our aim is to secure the best deal you are eligible for from our panel of lenders. Lenders may pay a fixed commission to us for introducing you to them, calculated by reference to the vehicle model or amount you borrow. Different lenders may pay different commissions for such introductions, and manufacturer lenders linked directly to the franchises that we represent may also provide preferential rates to us for the funding of our vehicle stock and also provide financial support for our training and marketing. But any such amounts they and other lenders pay us will not affect the amounts you pay under your finance agreement, all of which are set by the lender concerned. If you ask us what the amount of commission is, we will tell you in good time before the Finance agreement is executed. All finance applications are subject to status, terms and conditions apply, UK residents only, 18’s or over. Guarantees may be required
