Of the 25 employers already using NEST, case studies of the early experiences of three firms, F2 Chemicals based in Preston, Metal Assemblies, based in West Bromwich, and Positive Support in Tees CIC, based in Hartlepool, were shown at an event to showcase NEST's work to date, held in London today.
Some of the larger employers also considering using NEST include Gondola Group (which includes companies such as Pizza Express), Sodexo, Spirit Pub Company and Travelodge.
Tim Jones, chief executive of NEST Corporation said: "The NEST Live event demonstrates how employers of all shapes and sizes are choosing to use NEST because it is meeting their needs, and the needs of their workers.
"Many of these employers are joining NEST and getting ready for automatic enrolment well ahead of their staging dates, which is incredibly encouraging. Others are getting their plans in place ready for automatic enrolment and using NEST as part of their solution alongside other schemes - that's exactly the role NEST is here to play.
"We've been launching NEST progressively over 2011 with volunteer employers to ensure it works well for employers of all sizes. The feedback we've received to date has been very good - employers tell us that they like our fresh approach to important issues such as communication and investment, and they particularly like how easy NEST is to use."
Minister for pensions Steve Webb added: "Our plans to get people into workplace pensions will mean that millions will be saving for their retirement for the very first time. NEST is critical to our plans, as a low cost and easy to use option that is designed for people who are new to pension saving.
"I'm very pleased to see that employers are engaging with the upcoming changes and the strong response that NEST has received so far."
