Social Etiquette in the UK

The British are famous for their language, sense of humour and, of course, politeness. So, when you are in the UK, make sure you respect the social etiquette in the following situations:

British people are quite reserved when greeting one another. A handshake is the most common form of greeting when you meet someone for the first time. It is only when you greet close friends or relatives that you would kiss them on the cheek or give them a hug. The British may also call you by many different affectionate' names, such as dear, chuck, mate, guv, son or madam. Do not be offended, this is quite normal.


The British like their privacy, so not all topics are safe for small talk. Avoid asking people about their age, religion, politics, marital status, weight or how much they earn. Instead, acceptable small talk topics are family, films, television, sport, studies, food, hobbies and of course, the weather!

When you visit people at home, make sure you are on time. It's also nice to take a gift for your hosts, such as a bottle of wine, a bunch of flowers or a box of chocolates. A British person might say 'come and see me soon' or 'drop in anytime'. However, you must always phone before you visit someone
