He had 5♥/3♦ nothing documented on agreement
In the UK we are told to alert if we're not sure what a call is but it may be conventional and explain that "we don't know what it is but we don't think it's natural".

I agree with Pran:
This gives UI and it doesn't solve a problem. It is still MI and the opponents are entitled to redress if they are damaged.
After all, the correct information is either of:
"We do not have an agreement."
"We do have an agreement and it is... "
I would prefer an alert (if it could be alertable) and -when asked- simply followed by: "I don't know." The last part also is UI, but it contains all the relevant information and nothing more.

It seems to me you are bound to provide your opponents MI no matter what you do, even if you do nothing. Some scenarios:
1. You do/say nothing, and it turns out you have an alertable agreement. MI. The lack of alert conveys (not "is") UI.
2. You alert, and they don't ask. It turns out you don't have an alertable agreement. MI. The alert conveys UI.
3. You alert, and they don't ask. It turns out you have an alertable agreement. No MI. The alert conveys UI.
4. You alert, and they ask. You say "I don't know". MI. Both the alert and the statement convey (probably the same) UI.
5. You alert, and they ask. You say "I don't know, look at our card". The information is on the card. No MI. UI.
6. You alert, and they ask. You say "I don't know, look at our card". The information is not on the card. Possible MI. UI. Whether it's MI depends on whether there's no information on the card because you forgot to put it there, or because you have no agreement, or because your agreement is that it's natural and there's no reason to put it on the card.
If, as happened once to me, they say (in the event she said it rather superciliously, but however it's said) "I don't look at convention cards, I ask questions!" call the director and tell him what happened and that you are annoyed and disconcerted by your opponent's attitude (unless you really don't care about that).
Whatever happens, at some point the director is going to have to investigate whether you really do have an agreement, and if so, what it is. And then the impact of MI and UI on the deal.
I think it's best to alert if you think there may be an alertable agreement, and to say "I don't know, look at our card" if they ask. BTW, in England, at least, if you think it's natural, in most cases you would not alert it, so while "I don't think it's natural" is extraneous if you do alert it, I don't think it conveys anything potentially useful to partner.
Also, you should make darn sure that before you leave the site (and preferably before the next round) you discuss this with your partner and come to a firm agreement, and then
remember that agreement. If it later turns out that you keep forgetting it, replace it with an agreement you
can remember.
