Explanation
In the United Kingdom, public displays of affection at social gatherings are generally acceptable but should be subtle and restrained. A brief kiss on the cheek or holding hands is fine, but prolonged or passionate displays can make others uncomfortable, as British social norms value personal space and understated behavior.
Local Tip
Keep any physical affection brief and low-key, such as a quick hug or a peck on the cheek, and read the room to match the group's comfort level.
How it compares elsewhere
Kissing on both cheeks as a greeting is standard, and moderate PDA is common in social settings.
Any public display of affection between unmarried couples is illegal and severely frowned upon.
PDA is very rare; even holding hands can be seen as immodest in many social contexts.
