I'm also in London and I have never been asked if I own or rent on any application for either primary or secondary.

And maybe applying from a rental while owning elsewhere will be within the rules in many places too.
But if you're in an inner London borough, it's a very different story. The inner London boroughs share a common admissions procedure and guidelines for addresses. They set out the requirements very clearly, and these rule out using a rental address if another property is owned, even if it's being renovated.
So if - for these boroughs - you declare a rental address, and don't mention any other address, you are implicitly declaring that you don't own a property.
The guidelines also state that places offered on the basis of "false or misleading information will be withdrawn".
The upshot is that if someone lives in these boroughs (Lambeth and Wandsworth are two examples) and they omit to declare property ownership on their application from a rental address, then any place they get will be withdrawn once the council catch up with them, whether it is straight away or after their child has started at the school.
This absolutely is enforced all the time, it's not some theoretical worry.
Theoretically the place could be withdrawn even if their child had been in the school for years. As would any places for other children admitted under sibling rules.
If they appealed then they would be up against it, because the burden of proof would rest on them. Ignorance of the guidelines would not be an excuse. They would have to prove that they had not intentionally misled the council. I'm not even sure how you'd start going about that.
I think many other areas of the country might not have this prohibition on rental applications, because they don't have the same pressure on places as London.
My advice on someone thinking of renting to apply would be to check the rules where they are applying very carefully to make sure you're not opening yourself up to that kind of outcome. It's not a nice feeling looking over your shoulder in case the council catch up with you, maybe for years. I can understand how people rationalise getting around the rules to themselves, but they risk landing themselves in a terrible position.
