It is usually possible to find out whether a deceased person had any dormant bank accounts, insurance policies, pensions or store accounts without incurring a fee.
FIND 'UNCLAIMED' ASSETS
Searches for unclaimed assets can only be done by a legally entitled person i.e. someone who holds the appropriate Power of Attorney or the Executor/Administrator of an estate to act on their behalf. Separate applications must be made for every individual whose assets may be missing.
Here are some free online tools for helping you track down lost or dormant assets:
For lost pensions held in the UK you can call the Pension Tracing Service on 0800 731 0193, or via the UK GOV website here
Bank Accounts and Savings
For any bank, building society or National Savings & Investments accounts, this website will guide you through some simple steps to help find out if you have any un-claimed assets.
There are also commercial services which can be used although there will normally be a charge.
