Can I still use an R44.03 or R44.01 car seat in the UK?

Which R44 amendment numbers are still listed for use?

RoSPA’s Child Car Seats use list is the line most loft and grandparent seats fail: the restraint must conform to UN ECE R44.04 (or R44.03), or to R129 (i-Size), and display an E-mark. “Older ones that conform to a British Standard or to an earlier version of R44 cannot be used.”

The Milton Keynes University Hospital NHS leaflet repeats the same three marks: UN R129, UN R44.04 or UN R44.03. It adds that .03 seats are no longer sold as new but “can still be used”. GOV.UK’s public rules page says ECE R44 with an E-mark for weight-based seats; it does not spell out .01 versus .03.

Is R44.01 treated the same as R44.03?

No. ChatGPT-style summaries that say “old R44 is illegal” collapse three different stickers. R44.04 and R44.03 are the amendments RoSPA still names. R44.01 (and R44.02) are the “earlier version of R44” RoSPA says cannot be used, together with British Standard-only seats.

The number is a small print line on the orange approval label — 44.03, 44.04, 04, or similar — not the word “R44” on a Facebook listing. If you only know “it is an R44 from the loft”, you have not yet read the amendment.

How do I read the amendment number on this seat?

1. 1
   Find the orange approval label It is usually on the back or underside of the shell. You need the capital E in a circle plus the regulation line. This page stops at the amendment digits. It is not a full orange-label walkthrough.
2. 2
   Copy the regulation and the .0x Look for ECE R44.04 / 44.04, ECE R44.03 / 44.03, or R129. If you see 44.01 or 44.02, that is the earlier group RoSPA excludes.
3. 3
   If there is only a British Standard kite or no E-mark RoSPA: British Standard-only seats cannot be used. Do not treat a faded UK sticker as R44.04.
4. 4
   If the label is missing or unreadable You cannot show R44.03, R44.04 or R129. Official records do not give that seat a pass. That is a reason not to use it, not a reason to guess .04.

Manufacture date, crash history and missing instructions are separate checks (RoSPA discusses crash replacement and missing manuals). This page is only the amendment number.

Does Northern Ireland list R44.03 as well as R44.04?

nidirect says any child restraint used must conform to Regulation 44.04 or Regulation 129. That sentence does not add .03. RoSPA and the MKUH leaflet (England) do add .03.

If the seat is in Northern Ireland and the orange label is R44.03, do not rely on a GB blog that copied RoSPA only. Read nidirect’s wording against that sticker. R44.04 and R129 are the pair nidirect names for use.

What about a loft seat or a grandparent’s old R44?

Those seats are why the amendment number exists as a search. Many are R44.01 / .02 or British Standard-only. Calling the whole pile “illegal old R44” is wrong for a labelled R44.03 or R44.04. Calling the whole pile “fine because R44 is still legal” is wrong for .01 and for a kite-mark-only seat.

Which? still describes R44.03 or R44.04 as the older regulation that remains legal in the UK. That sentence is about those amendments, not about every seat that once said R44.

In shortIn short: RoSPA lists R44.04 or R44.03 or R129 with an E-mark. Earlier R44 (.01 / .02) and British Standard-only seats cannot be used. R44.01 is not on the use list. In Northern Ireland, nidirect’s use sentence names 44.04 or 129.
