How old can the CENOMAR be that must be presented as proof the my fiance has never been married?

I am arranging a marriage here in the UK. One of her requirements is that she must produce a document to prove she has not been married. She has her CENOMAR but Ive just noticed this was issued March 2022, so its over 1 year old now. Will this be accepted by the marriage Registar? For a Philippine marriage it is only valid for 6 months but I cant see anything about how long it can be valid for under UK marriage regulations.

I would play it safe and maybe get a new one (just my personal view) as it only costs 430 peso and you get it in a couple of days on line. Would be a really bummer if your other half came to UK and something like that scuppered your plans

I have just searched and it is only valid for 6 months, so get a new one
