For most homes, the report says national flags can be displayed without formal approval if basic conditions are met.
There is also a practical limit on multiple displays. The update says two flags can be shown on the same fixed pole only if one is a permitted national-style flag and takes the higher position.
The legal risk rises once a flag leaves private space.
On public property, the line appears firmer. Attaching flags to lampposts, bridges or similar structures reportedly requires local authority consent. The report adds that ignoring a council request over a non-compliant display could lead to a fine of up to £2,500.
Tournament fever often spills into streets and neighbourhoods, not just stadiums. That is why these rules come back into focus every major summer. The report says the competition begins on 11 June, with Scotland due to face Haiti on 14 June and England meeting Croatia on 17 June.
The next storyline is obvious: as those fixtures approach, expect more flags to appear - and more reminders that backing your team still comes with boundaries.
