@Peadar - this takes you straight to the O2 web top-up site, just ignore the login prompt at the top, *carefully* enter your wife's number and follow the prompts. There used to be a restriction if 2 unique O2 numbers per payment card, so be prepared to use a different card or one of the other methods in the link shared above by @jonsie -
