Actually the 10y that's been quoted is from New Zealand though they have it for UK Britax seats.
I have checked with Britax re. life span of UK Britax car seats and the response wasn't very reassuring to say the least.
My email query -
Could you please explain when a Britax car seat expires? I read on your
UK website that as long as the car seat meets ECE R 44/03 or above the
car seat is safe to use no matter how old. As ECE R 44/03 was introduced
in February 1997, could a seat that is 12 years old ( I asked this in 2009) be still considered safe when according to the Britax USA site
www.britaxusa.com/customer-service/faq/retired-products seats
do have an expiry date due to component degradation (plastic degrades
over time) amongst other reasons. I am a bit confused that seats expire
in the US but not it the UK. Could you explain as I don't want to use a
car seat beyond it's safe life.
Britax's reply -
Thank you for your email.
As the legal requirements of the European and Federal Standards (USA) are incompatible this means they have different regulations they can comply to. As it states on our website as long as the product has not been involved in an accident and is approved to the current safety standard ECE R 44/03 then it is safe to use. Obviously our newer products are now more advanced with side impact protection so it would be your choice on whether you purchased a newer product.
I hope this is helpful.

Weasel words IMVHO.
I have posted this before so I'm just going to C&P (posted in April 2011) & this is why I wouldn't use a old car seat bearing in mind this was a well looked after, occasionally used, carefully stored in a cupboard on an internal wall & never been in an accident/dropped car seat.
'While I think your seat should be safe have a look at the plastic shell for stress marks (white or light coloured marks on the plastic) before using it again and check the straps/harness for fraying or damage.
The reason I say this is because I've just checked our spare baby bucket (DD3 is now too tall for it at 18m) and it's DOM is June 2006, it is a cheap seat though - a Team Tex one (aka Nania).
It looked in good condition so I was tempted to freecycle it on the proviso it was only used for a few months but on closer inspection the navy blue plastic was covered in light blue/white stress marks. I've now stripped it down and removed the straps/cover so I can take it to the tip and no-one would be able to reuse it. It just doesn't look safe and I'm glad we never had an accident with one of the DDs in it.
It's not even 5 years old yet and is our spare seat so was used at most 25 for 3 babies (DD3 used it for the longest - trips in ambulances being the most common reason for use!).
It was stored indoors in a cupboard and was never kept in a car for a long period (perhaps a few hours) so was not exposed to the extremes of heat/cold a seat might if it was kept for years in a car. I don't know why it has stress marks on it.'
