Building Society Dormant Account & Lost Savings Guide
Found an old passbook, remembered a childhood savings account or lost track of money after moving house? A building society dormant account does not mean the savings have disappeared. In most cases you can trace the account, prove your identity and reclaim the money even after many years.
If you know which building society holds the account, contact it directly first. If you do not know the current provider, or the old society has merged or changed name, use the Building Societies Association tracing information and the free My Lost Account service.
Meaningful editorial review: 23 September 2026. My Lost Account procedures, Building Societies Association merger records, Nationwide, Coventry and Yorkshire dormant-account guidance, the UK Dormant Assets Scheme and current reclaim rights were checked for this update.
Dormant Building Society Account: Quick Answers
What Should You Do With a Lost Building Society Account?
Contact the society directly. This is usually the fastest route because it can search its own active, inactive and dormant records.
Search the BSA merger and name-change records to identify the current successor before contacting anyone.
Use My Lost Account and provide as much information as possible about former addresses, names and likely providers.
BSA guidance tells people who know the account is with Nationwide or a Nationwide predecessor to contact Nationwide directly.
Search as executor, administrator or next of kin, then provide the legal documents the provider needs before it can pay the estate.
Do not rely on the personal-account My Lost Account route. Identify the provider or successor and ask about its organisational lost-account process.
Dormant, Inactive, Lost and Closed: What Is the Difference?
These words are often used interchangeably, but they do not always mean the same thing. A provider can apply an internal inactivity flag before an account reaches the statutory 15-year dormant-assets threshold.
Use My Lost Account if You Cannot Find the Provider
My Lost Account combines the lost-account tracing schemes of the Building Societies Association, UK Finance and National Savings & Investments into one free online service.
It is particularly useful when you remember having savings but are unsure which provider now holds them, or where an old institution has merged, converted or changed name.

Information That Can Help Find an Old Savings Account
You do not need every item below to begin a search. Older addresses and names can be particularly important because the provider may be trying to match records created decades ago.
What if the Building Society No Longer Exists?
This is common. UK building societies have merged, changed names, transferred their business and in some cases converted into banks. The name printed on a 1980s or 1990s passbook may therefore be very different from today’s provider.

After opening this link:
- Enter the exact building society name shown on the old passbook or statement.
- Check whether it changed name, merged, converted to a bank or transferred its engagements.
- Write down the current successor organisation.
- Use the successor’s official website when you know who holds the records.
- If ownership is still unclear, continue with My Lost Account rather than guessing.
Lost Nationwide Building Society Accounts: Use Nationwide Directly
Nationwide has a specific lost-account process. The BSA also says that if you know the account is with Nationwide, or was with a society that merged into Nationwide, you should contact Nationwide rather than submitting the normal building-society lost-account application.
Official NationwideFind a Lost Nationwide Account
After opening this link:
- Read the section describing Nationwide’s 15-year unused-account process.
- If the account still exists but Nationwide has written about reactivation, follow the reactivation route shown.
- If the dormant account was already closed, find your nearest Nationwide branch.
- Take acceptable identification with you.
- Tell the branch if the account originally came from an older building society that merged into Nationwide.
- Keep copies of any historic account documents until the claim has been completed.
How Other Building Societies Handle Dormant Savings
There is no single customer-service process used by every society. The 15-year Dormant Assets Scheme threshold is important, but reactivation, closure notices, identification and scheme participation can differ.
What Happens to Money Under the UK Dormant Assets Scheme?
The Dormant Assets Scheme was created under the Dormant Bank and Building Society Accounts Act 2008 and began operating in 2011. It was later expanded under the Dormant Assets Act 2022 to cover additional financial assets.
For bank and building society accounts, the key statutory dormancy definition remains no customer-initiated transactions for at least 15 years. Participating firms must first make appropriate attempts to reunite owners with their money.
Official government guidanceUK Dormant Assets Scheme
After opening this link:
- Read the explanation of how dormant assets are identified and transferred.
- Note that participation by financial firms is voluntary.
- Read the section explaining the owner’s continuing reclaim right.
- For a lost bank or building society account, follow the link to My Lost Account rather than contacting Reclaim Fund Ltd as if it were a normal savings provider.
Do Dormant Building Society Accounts Still Earn Interest?
The answer depends on the provider and what has happened to the original account. A society may continue the account, close it and calculate a replacement entitlement, or transfer an eligible balance into the Dormant Assets Scheme.
Tracing a Dormant Account for Someone Who Has Died
My Lost Account can also be used where you are searching for savings belonging to a deceased person. The application asks for the date of death, and the eventual account provider must confirm that you are legally entitled to deal with the money.
Found an Old Building Society Passbook?
Keep it. A passbook can contain several clues that make tracing easier: the original society name, account number, branch stamp, old address and approximate transaction dates.
- Do not throw the passbook away even if the society name no longer exists.
- Write down the exact society name and account number privately.
- Check the BSA old-building-society records to identify the current successor.
- If a current provider is identified, contact that provider through its official website.
- If the successor remains unclear, submit a free My Lost Account search.
- Keep the original passbook until the provider confirms whether it needs to inspect it.
What if My Lost Account Says No Match?
A no-match result does not always prove that the savings never existed. Historic records can be under a different name, address, predecessor society or account holder.
Lost Savings Scams: What Not to Share
Forgotten savings can attract tracing scams because claimants expect identity checks. Genuine identity verification does not mean you should give sensitive information to anyone who contacts you unexpectedly.

Building Society Dormant Account FAQs
1. What is a dormant building society account?
A dormant account is a savings or other eligible account that has been unused for a long period under the provider’s rules. For the statutory UK Dormant Assets Scheme covering bank and building society accounts, the key definition is generally no customer-initiated transactions for at least 15 years.
2. Do I lose my building society savings after 15 years?
No. A participating provider may transfer an eligible dormant balance into the Dormant Assets Scheme after the required process, but the owner’s right to reclaim what they are owed is protected. Dormancy does not mean the money simply becomes the building society’s property.
3. How do I find a lost building society account?
Contact the building society directly if you know which provider holds the account. If the provider is unknown or an old society has merged or changed name, use the Building Societies Association tracing resources and the free My Lost Account service.
4. Is My Lost Account free?
Yes. My Lost Account states that its tracing service is free. You do not need to pay a commercial tracing company merely to submit a normal search for a lost UK personal bank, building society or NS&I account.
5. How long does a My Lost Account search take?
My Lost Account currently states that you will receive responses from the account providers selected in your search within 90 days. Individual providers can finish earlier.
6. What if my old building society no longer exists?
Search the Building Societies Association’s merger and name-change records. They can show whether the society merged, converted to a bank, changed name or transferred to another institution, helping you identify the current successor.
7. What should I do if I find an old building society passbook?
Keep it safe. Note the exact society name, account number and historic address without publishing those details online. Use the BSA old-society finder to identify the current provider, then contact that provider or use My Lost Account if ownership remains unclear.
8. Can I trace a dormant account belonging to someone who died?
Yes. My Lost Account supports searches involving a deceased saver and asks for the date of death. If an account is found, the provider will require evidence that the claimant is legally entitled to deal with the estate before releasing the money.
9. Does a dormant building society account still earn interest?
It depends on the provider and what happened to the original account. The reclaim principle is designed to preserve what the saver would have been owed, and some building societies expressly state that accrued or equivalent interest is included when dormant money is reclaimed.
10. Can I reclaim money after it has gone into the Dormant Assets Scheme?
Yes. Owners retain the right to reclaim eligible dormant money after transfer into the Scheme. For bank and building society accounts, start with the provider, successor institution or official lost-account tracing route rather than treating Reclaim Fund Ltd as an ordinary customer savings account provider.
