A heist is a theft of cash or valuable objects such as artworks, jewellery or bullion. This can take the form of either a burglary or a robbery, the difference in English and Welsh law being that a robbery uses force (which means that some of the heists commonly known as robberies were actually burglaries). In order to be listed here, each heist which took place in the United Kingdom is required to have taken a total sum of £1 million or more in cash or goods at contemporary rates.
