Employers and employees will pay contributions into pension savings unless the employee opts out.
However, this system will be phased in gradually, with workers in the smallest firms not seeing a change for a few years.
The Department of Work and Pensions (DWP) estimates that 380,000 workers will be signed up in October 2012, a total of 420,000 will be enrolled by the end of November, and 600,000 will be in place by the end of the year.
The aim is for more people to save for their retirement, rather than relying solely on the state pension. Single people can get a maximum of £107.45 a week basic state pension (in tax year 2012-13) so the need for additional savings is evident.
