Pension auto enrolment in the UK began in October 2012. The main reason for its introduction was to address the issue of inadequate retirement savings among the working population. Many people were not saving enough for their future, which led to concerns about the sustainability of the pension system and the financial well-being of individuals in their old age. The auto enrolment scheme was designed to make it easier for employees to save for retirement by automatically enrolling them into a workplace pension scheme and requiring employers to contribute towards their employees' pensions. This was seen as a way to encourage more people to start saving for retirement and help ensure that they have a more secure financial future.
