The Pensions Advisory Service has created the online aid, which is available from its website.
The organisation said it gets contacted by lots of savers each year asking for help in finding a pension they may have lost.
Michelle Cracknell, TPAS Chief Executive, said: “Every year our service is contacted by hundreds of people asking about how they can locate a pension they contributed to. Many of the people who contact us struggle to find lost pensions or may not even know how to begin the process.
“Our new ‘trace a lost pension’ tool helps customers understand whether a pension is likely to be due to them and gives them tips on what they can do to find them. It also explains how we can help.”
TPAS is also launching a Twitter campaign from 12 to 16 September, to offer some tips on how to find and, how to keep track of later life savings.
In the launch material for the tracing tool, TPAS stated: “Losing a pension continues to be an issue for many, especially when you have been in more than one scheme, have changed employer or moved home.
“But, there are some simple tips you can use to help keep track of your pension pots, including making sure contact details are up to date. Whatever the reason for losing track, it’s important that you claim your pension entitlement as soon as possible.
“Everyone has a habit of losing track of things from time to time, but when it comes to your pension(s) it’s not something anyone should misplace. Have you checked whether you have any pension due to you from all of the employers you’ve worked for?
“There are millions of pounds sitting in lost pensions. Could some of it be yours?”
