Should I accept a used car seat from family or grandparents in the UK?

What do RoSPA and the Lullaby Trust each say?

Mums and grandparents often argue from different pages. Both UK organisations publish a line; they are not the same. MayTally quotes them side by side and does not choose one for you.

RoSPA also calls child seats "one hit" products: they must not be used again if involved in an incident, because internal structure can change even when the outside looks unmarked.

What should I ask mum, dad or the grandparents before I say yes?

"It's from family" is not the same as RoSPA's absolutely certain history. A grandparent's spare that sat in a second car still needs a conversation you can repeat.

1. 1
   Who has owned it, start to now Was it bought new by this person? Has it been in any other household, loaned to another family, or bought used first? If the chain breaks, you no longer have RoSPA's known history.
2. 2
   Every car it has travelled in Ask about collisions, parking bumps and "just a shunt on the school run". RoSPA's insurer letter treats a seat that was in a car during an accident as a replacement case even when damage is not visible, unless a narrow set of conditions all apply.
3. 3
   Instructions and parts RoSPA wants the original instructions. Lullaby Trust says you can usually download a PDF if the booklet is lost — but only once you have the exact model. Check the base, inserts and any support leg are the ones that came with that seat.
4. 4
   How old, and what the maker says RoSPA: check the manufacturer's advice about how old the seat should be before it needs to be replaced, and do not accept one that is too old. Ask when it was bought. Do not guess from how "new" the fabric looks.
5. 5
   Try it in every car that will carry the child RoSPA: try the seat in your car; if you cannot get it to fit securely, do not take it. Which? adds grandparents' cars. A seat that clicked in Nan's hatchback may not lock in your Isofix.

When is a family offer still not RoSPA's test?

• They think it was never in a crash but are not sure — RoSPA's word is "absolutely certain".
• It came from a neighbour, NCT group or Facebook friend-of-a-friend — that is not the family-or-friend exception as written.
• The booklet is gone and the model label is worn off — you cannot show original instructions or match a PDF.
• It has been in a loft, damp garage or a car that was written off — you no longer have a simple stored-in-the-house history.
• It does not fit your car or the grandparent's car — RoSPA says do not accept a seat you cannot fit securely.

The Lullaby Trust's line still applies on top of that list: even a known family seat is, in their words, best replaced with new because wear is not always obvious. That is their published advice, not a MayTally verdict.

Does a family seat skip the approval-label check?

No. RoSPA still says check the seat meets UN Regulation 44.04 (look for the E mark) or is an i-Size seat, and that it suits your child's weight and height. NHS says look for R44.03, R44.04 or R129 and the E mark. This page does not teach how to read every line of the orange label — only that the label should be there so you know which seat you were given.

A grandparent may also offer an older spare "for the taxi to ours". The history questions still apply to that spare. Official pages do not create a short-trip exception.

How do I say no to grandparents without a row?

You can quote the pages rather than invent a family rule. RoSPA's best advice remains a new seat; the Lullaby Trust says it is still best to buy new even when the seat is from family. NHS says ideally buy new. If money is the pressure, RoSPA suggests asking your council's Road Safety Department about any child-seat discount schemes — that is their wording, not a promise that a scheme exists where you live.

In shortRoSPA's family-or-friend exception is narrow: known history, original instructions, not too old, plus a secure try-in-car. The Lullaby Trust still prefers new even then. MayTally will not pick a winner. If any of RoSPA's conditions fail, you do not have that exception.

If I accept it, what do I still need to do?

Keep the instructions with the seat. Fit it using that booklet, not memory of how it sat in the other car. Search the model on the GOV.UK recall list. No listing means no recall on file. Book a local fitting check if your council or a clinic offers one — Good Egg-style checkers say they can confirm a fit, not the seat's unknown past.
