Pensions minister Steve Webb has hailed the Government's landmark retirement savings reforms as a recipe for success as he celebrated the first year of the initiative at bakery chain Greggs.
The retail giant, which features in the Government's advertising campaign to promote automatic enrolment into workplace pensions, announced that one in 15 (6.5%) of its employees had opted out of its pension scheme after being placed in.
Auto-enrolment started last October with larger firms, and so far the rates of people remaining in their pension have been much higher than industry expectations, with fewer than one in 10 (9%) of workers opting out.
More than 1.6 million workers have already been automatically enrolled and the scheme will eventually reach up to 11 million people as it rolls out over the next five years.
Speaking at a Greggs bakery in London, Mr Webb said: "Over the last year, we have instigated a quiet revolution that has heralded the biggest change to pensions in a century.
"Already, over 1.6 million people have been automatically enrolled and the early signs are that this is an enormously successful scheme with nine out of 10 workers choosing to stay in a pension."
Jonathan Jowett, Greggs company secretary, said the chain was "delighted" to have auto-enrolled 7,466 members of its workforce with such low opt-out rates.
H e said younger workers in particular were keen to start retirement saving.
Mr Jowett said: "As an employer to just under 20,000 people, we are proud to be helping people save for life after the world of work and the auto-enrolment scheme is the easiest way for them to do it. "
Businessman and former Dragons' Den star Theo Paphitis, who is seen in the Government's auto-enrolment campaign alongside The Apprentice's Karren Brady and Nick Hewer, said in a statement that he was "proud" to be involved.
Mr Paphitis, owner of stationers Ryman, hardware chain Robert Dyas and lingerie brand Boux Avenue, said: "I want the people I work with to be able to plan for their retirement; saving into a pension does exactly what it says on the tin.
"As an employer, I am proud to be able to contribute to their future."
Employees from companies including Homebase, Siemens and the Co-operative Group are also involved in the advertising campaign to promote auto-enrolment.
The Government has been praised for its efforts to see off a looming retirement savings crisis, as people are living for longer but are failing to put enough money away to live comfortably in their old age.
Office for National Statistics (ONS) figures recently showed that the number of private sector workers saving into a company pension fell to an all-time low, since records began in 1953, of 2.7 million last year, just before automatic enrolment started.
The peak for private sector pension saving was in 1967, when 8.1 million people were saving into a pension.
But a recent report by the Office of Fair Trading warned that more work still needed to be done to make sure employers did not place workers into schemes with rip-off charges which could shrink the size of someone's eventual pension pot.
Concerns have been raised that smaller employers in particular, who have less experience of pensions, may be more at risk of choosing a poor-value scheme.
The industry is working to improve the transparency of schemes.
