"Pretty much, yes — Ground 14ZA is a mandatory possession ground (under Schedule 2 of the Housing Act 1988), which means:

If you (or any adult living there) are convicted of an indictable offence at a UK riot,

The landlord can serve a 2-week notice and apply to court,

The court must grant possession unless there’s a technical error (e.g., notice not served properly).

The landlord is fully protected legally in doing so — the conviction alone is enough proof. They don’t need to show you damaged the property, threatened neighbours, or anything tenancy-related.

This ground was added after the 2011 London riots (via the Anti-Social Behaviour, Crime and Policing Act 2014) as a way to let councils and private landlords “deal with” tenants involved in large-scale disorder.
Important details:

It only applies if the offence is indictable (serious — e.g., violent disorder, burglary, arson), not for minor offences like obstruction.

It’s not triggered by lawful protest — only where a court convicts you for something during a riot.

The landlord still has to follow procedure (serve proper notice, go to court), but the court doesn’t get to weigh “reasonableness” — the conviction is all that matters."
