Lost a UK savings account? The search is free, but a match is not a payout
Old names and addresses can help trace forgotten bank, building society and NS&I accounts. Finding a record is only the first step towards reclaiming any money.

An old savings booklet turns up in a box after a house move. The name on it is familiar, but the address is out of date and the building society may no longer trade under that name. The useful question is not how much a recovery firm would charge. It is which provider can check whether the account still holds money.
For UK personal accounts, My Lost Account offers a free tracing route covering banks, building societies and National Savings and Investments, known as NS&I. It brings together the tracing schemes of UK Finance, the Building Societies Association and NS&I. There is no need to pay a fee to use that service or approach the provider directly.
But a search result is not a payment instruction. The provider must establish identity and entitlement before returning money. That distinction matters whether the clue is an old passbook, a remembered childhood account or paperwork found while dealing with a relative's affairs.
My Lost Account's starting guidance makes a distinction that can save an unnecessary detour. Someone who knows which bank or building society holds the account should contact it directly to ask whether the account is still open. The same applies to known NS&I accounts or product numbers.
The tracing service is intended for accounts marked as lost, particularly where the holder is unsure which provider now has them. It is not a search of every active account in a person's name, and it is not a universal register of everything someone owns.
A change of address is the most typical reason for losing contact, according to the service. Providers try to reconnect with customers, but may eventually stop sending correspondence to an address where the customer no longer lives. That helps avoid disclosing financial details to the wrong person. Silence from a provider does not, on its own, settle whether money remains.
The search form asks for as much information as possible. Available account numbers and sort codes can help, but the service also draws attention to previous names, former addresses and accounts opened by parents or guardians. A childhood account may have been held jointly or under a name that has since changed.
Those details are search clues, not a reason to publish a photographed passbook or personal records online. The information belongs in the provider's or tracing service's application process, rather than a public request for help.
An unfamiliar institutional name is not necessarily a dead end. My Lost Account's provider search includes defunct bank and building society names alongside their successors. Its FAQ tells applicants dealing with a closed or merged institution to select the original provider from the menu. A free-text field allows further details.
The practical point is to preserve what the old paperwork actually says. Replacing a remembered name with a guess about today's banking group can lose a useful clue. A merger does not itself prove that an account survives, but the disappearance of a brand is not proof that its records have vanished either.
Information submitted through My Lost Account goes to the providers selected in the application. Those providers search their lost-account records and report whether they have a match. It is not an instant balance lookup.
The service says responses should arrive within three months. Online applicants receive alerts as bank and building society searches finish, with updates available through their profile. NS&I results, and results for people using the relevant paper route, arrive in writing. An alert that a search has finished should not be read as confirmation that money has been found.
If an account is located, the provider explains what is needed next. Identity checks still apply. A person acting for someone else also needs the relevant authority; finding their paperwork does not confer ownership or a right to withdraw funds.
NS&I's own tracing guidance is explicit that a search on another person's behalf requires legal entitlement to act, for example as an executor or under a power of attorney. It asks for a separate application for each person. These are safeguards around access, not a fee payable to release a successful search result.
My Lost Account's FAQ says money in an account with no customer contact for 15 years may be transferred to Reclaim Fund Ltd under the dormant-assets scheme. It also says that transfer does not remove the legally entitled account holder's right to reclaim the money.
That is different from an account that was closed after all its money was withdrawn or moved elsewhere. An old booklet is evidence worth checking, not proof of a present balance. The article makes no estimate of what any reader might recover.
Nor is 15 years a reason to postpone asking a known provider about a forgotten account. The immediate question is its current status, not whether a particular anniversary has passed. The service's lost-account criteria and a provider's ability to answer an enquiry are different things.
My Lost Account covers UK-based personal accounts. Overseas accounts, business accounts and charity accounts are outside that service's scope. Living abroad is a separate issue from where an account is held: its FAQ says a provider can explain how identity checks work for a claimant unable to visit a UK branch.
People dealing with a death should normally start with the known bank or building society, because the accounts may still be active. For NS&I, the service directs them to NS&I's dedicated bereavement route. Lost-account tracing is not a substitute for establishing who is legally authorised to handle an estate.
There are paper application routes for people unable to apply online, with separate forms for banks, building societies and NS&I. NS&I also accepts a signed, dated letter containing the information listed on its tracing page when someone cannot print its form.
The search can begin with incomplete memories, but it ends with the provider checking records and entitlement. A free route removes the need to pay for tracing. It does not promise that every old account contains money, or that a match can be cashed out without further checks.
Editorial note. This article provides general information about tracing UK personal savings accounts, not personal financial or legal advice. It does not establish anyone's entitlement to an account or advise on administering an estate. A provider's identity and authority checks, account records and the circumstances of a claim determine what happens next.
