My favourite quirks with tv licencing...Students living away from home do not need a separate tv licence to watch iPlayer on a laptop ... unless the laptop is plugged into the mains at the time of watching.
Indeed, and that applies to anyone, not just students.
Also applies to mobile phones and tablets, not just laptops.
If the device being used to watch whatever is plugged in to the mains to charge then a license at that property is required. If it's running on battery power then your own TV license is good enough regardless of where you are in the country.
Anyway the TV licensing thread is elsewhere...
