Business hours are officially Monday to Friday 0900-0930 until 1700 or 1730, although in practice many companies have much longer hours. Business in London is intense and fast paced. Extended business lunches and post-work drinks were regarded as part of the modern working environment until relatively recently. Nowadays, the emphasis is increasingly on hard work and long hours.

British businesspeople are unlikely to be overtly demonstrative - hand gestures and the use of expressive body language will be minimal and apart from shaking hands, physical contact should be avoided. Standard dress code is a suit and tie for men and a suit (or equivalent) for women but varies greatly depending on the company, with those in the new technologies sectors especially tending towards informality.
