Yes. If you’ve been working for a while, you may have lost track of your pensions with previous employers, or don’t remember whether you had a pension with any of them. It’s worth checking to see whether you have any forgotten pensions you could add to your pension savings.
You can contact the Pension Tracing Service or Money Helper for free guidance on tracking down lost pensions. Both services are independent and run by the government. They can also signpost you to independent financial advisers in your area.
