there is no specific national law in the United Kingdom that directly prohibits the use of refrigeration for iced beverages. The absence of widespread use of ice in beverages in the UK is more of a cultural preference rather than a legal restriction.
Historically, the British have not been as fond of iced beverages compared to some other cultures. In many parts of the UK, particularly in the past, the weather has been relatively cool, and hot temperatures are not as common as in some other countries. This might have contributed to a lesser demand for iced beverages.
Moreover, tea is a significant cultural aspect in the UK, and traditionally, tea is consumed hot rather than iced. The British tea-drinking tradition is deeply ingrained in the culture, which has influenced beverage preferences over time.
While there are no laws against using refrigeration for iced beverages, cultural factors and traditional preferences may have shaped the perception and consumption of cold drinks in the UK. It's worth noting that cultural attitudes and preferences can change over time, and there might be variations in preferences among individuals and regions within the UK as well.
