Auto-enrolment has made significant steps towards getting people in Britain into a workplace pension scheme.

Since its launch in October 2012, the government's plan to get more than 11 million people saving for a pension through a combination of auto-enrolment and behavioural inertia has seen more than six million people who were previously not saving for retirement building up a pension pot.

As the smallest and micro-employer are now in the middle of their staging process, the largest employer's schemes are coming up to their three-year review.

This guide explains what large and small employers need to consider, whether to switch providers, getting set up and communicating to employees what auto-enrolment requirements mean for them and how advisers can help support their corporate clients on this journey.
