It is by no means uncommon for people to have money in accounts which they or their relatives have forgotten about and the scale of the problem is illustrated by the fact that the National Savings and Investment Bank (NSIB) says it has £435 million in dormant accounts and bonds. An extra £23 million sits in unclaimed Premium Bond wins.
However, help is at hand. A website set up by the British Bankers Association, the Building Societies Association and the NSIB will allow the tracing of lost or dormant accounts to be simplified.
If you think you may have a lost or dormant account you can no longer find, look at the mylostaccount website.
