What should I do with a child car seat after a crash instead of selling it?

Why replace a child car seat after a crash?

RoSPA states that a child car seat that was in a car when it was involved in a collision should be replaced, even if there is no visible damage. The seat may have been weakened so it will not give the same protection in a later impact. That is a materials point, not a cosmetic one: a clean cover does not answer it.

The same RoSPA page says the seat belts and seat-belt attachments that were in use should be checked for damage, and that the replacement cost of the child seat should be included in the insurance claim. A marketplace listing does not do that work.

Official records show RoSPA’s position is replace-after-collision, not sell-on-if-it-looks-fine. Which? (2024 baby survey) found about one in ten parents still sold a car seat via an online marketplace when they no longer needed it — that channel is how crashed seats keep circulating.

What should I do instead of selling it?

Treat the seat as finished kit, not as stock. The job is to stop the next parent fitting it, then to deal with the insurer and the waste stream.

1. 1
   Stop using the seat Take it out of daily use. RoSPA’s collision page is about replacement, not continued use while you wait for a payout conversation.
2. 2
   Photograph the labels and the car Keep the model name, approval label and any claim reference. Insurers and makers ask for the model, not a marketplace screenshot.
3. 3
   Ask the insurer to include a replacement RoSPA tells insurers that replacement is a legitimate claim cost, in the same way as bodywork. If the insurer pushes back, use RoSPA’s letter for insurers (PDF).
4. 4
   Read the maker’s crash rule Some manufacturers publish when a seat must be replaced after an impact. That letter is a starting point; the model manual is the rule for that shell.
5. 5
   Destroy the harness before it leaves the house Cleveland Fire Brigade advises removing the cover and cutting the straps on damaged or old seats so they cannot be reused. Then take the shell to the household waste and recycling centre if your council accepts it.

Will insurance cover a replacement seat?

RoSPA’s insurer letter, signed by its Head of Road Safety, says a seat in a car that has been in an accident should be replaced even with no visible damage, and that insurers should regard the replacement cost as a legitimate cost. It also asks for seat belts and attachments to be checked. That is RoSPA’s ask of the industry, not a promise that every policy pays on first request.

The letter notes it is hard to judge how severe an impact needs to be to damage a seat. It lists cases where replacement may not be needed: a very low-speed impact, little or no external damage to the car, and no child in the seat. It then says the only reliable test would be a laboratory test that would itself destroy the seat. If there is any doubt, RoSPA’s public page is to replace the seat.

MayTally does not handle insurance claims. Send the RoSPA PDF to the claims handler and keep the model label. A declined claim is not a reason to list the seat for sale.

How do I stop someone else using the crashed seat?

Cleveland Fire Brigade, writing with the Cleveland Strategic Road Safety Partnership, tells parents disposing of damaged or old seats to remove the seat covers and cut off the straps so they cannot be reused. That is the local fire-service disposal line, written because a previously damaged seat may show no visible signs and still be weakened.

• Cut the harness webbing in more than one place so the seat cannot be buckled again.
• Take the cover off and keep it out of the shell if you are leaving the seat at a tip.
• Write on the plastic that the seat was in a collision, if the shell is still readable.
• Do not leave an intact seat on the kerb ‘for someone who needs it’ — that is another listing.

Which? reports that recycling a car seat is a postcode question: some household waste sites take rigid plastics, some do not. Ask the site first. Cutting the straps is the fire-service step that matters even if the plastic later goes to residual waste.

What if it was only a minor bump?

RoSPA lists the low-speed, little-damage, empty-seat caveats, then says it is very difficult to be sure and that if there is any doubt, replace the child seat. Some makers publish their own crash-replacement rule. Read that rule for the model you hold. Do not invent a ‘parking-ding is fine’ threshold from a forum.

A seat that was not in the car at the time is a different object. The RoSPA collision page is about a seat that was in the vehicle. If the seat was at home, the crash-replacement rule does not apply to that shell — wear, age and missing parts still do.

In shortAfter a crash: replace the seat, put the cost on the insurance claim, and cut the straps before the shell leaves the house. Official pages do not treat ‘it looks fine’ as a reason to sell it on.
