How to Find Lost Investment Accounts in the UK (Step-by-Step Guide)
In short: There is no central register of investment accounts in the UK. To find lost or unknown investments, families need to review financial records, analyse bank transactions, search digital accounts, identify providers and contact investment platforms directly.
Introduction: Why Investment Accounts Are Often Overlooked
When someone dies, identifying investment accounts is often more complex than finding bank accounts or pensions. Unlike current accounts or workplace pensions, investments are frequently held across multiple platforms, jurisdictions and structures.
Investment accounts may include brokerage accounts, ISAs and General Investment Accounts, fund platforms, wealth managers, direct shareholdings, dividend accounts and digital investment apps. Many of these leave minimal or fragmented records, particularly if they are inactive or held digitally.
If you do not know which provider held the investments, you usually need to identify the provider yourself by reviewing documents, checking bank transactions, searching emails and contacting likely institutions directly. This guide provides a practical framework for executors and primary nominee to identify investment accounts, trace providers and support estate administration where financial records are incomplete.
Investment accounts are only one part of the broader financial picture. If you are also tracing bank accounts, see our related guide: How to Find Bank Accounts After Death in the UK.
The Reality Check: Why Investment Accounts Go Missing
Before starting, it is important to understand why investments are frequently missed:
- Multiple Platforms: Investors often use several providers over time (e.g. ISA provider, trading app, legacy broker).
- Provider Changes: Investment firms merge, rebrand or transfer client books.
- Digital-Only Access: Many modern platforms provide no paper statements.
- Dormant Holdings: Shares and funds can remain untouched for years while continuing to exist and grow.
- Overseas Exposure: International holdings may leave little trace in domestic records.
Common questions people ask when trying to find investment accounts after death:
“Can I search all investment accounts in one place?” → No
“Will investment firms contact families automatically?” → Not in most cases
“Can investments be lost permanently?” → No, but they can be difficult to identify
Step 1: Start With Known Financial Relationships
Do not begin by trying to “find investments” in the abstract. Begin by building a shortlist of financial institutions, advisers and platforms the person may have used.
Start by checking core sources where investment relationships often leave clues: paperwork labelled “ISA”, “investment”, “portfolio”, “shares” or “wealth” and any records referencing accountants, advisers or wealth managers.
Look for evidence of different types of providers, including traditional stockbrokers, wealth managers, digital investment platforms, trading apps, ISA platforms, robo-advisers, employee share plan providers and company registrars, and note any provider names that appear in adviser correspondence, employment records or supporting documents.
Review adviser and professional correspondence for clues such as annual review letters, suitability reports, consolidated tax certificates, meeting notes or even calendar entries referencing adviser meetings.
Check employment records for employee-linked holdings such as SAYE (Save As You Earn), SIP (Share Incentive Plan), share scheme enrolment notices or payroll records showing share deductions.
What to do:
Make a list of every provider, platform, adviser or firm name you find and add context beside each one, including what type of provider it is, where you found the reference, and whether it appears active or historic. Use this list as your working map for the rest of the search.
Example:
An email from “HL” (Hargreaves Lansdown) or a tax summary mentioning “AJ Bell” are high-priority leads, even if you don't yet know if the accounts are currently active.
This is the right place to start because investment accounts are usually found by reconstructing the person’s financial relationships over time.
Step 2: Analyse Bank Transactions First
For investment accounts, bank statements are often one of the strongest sources of evidence. They can reveal where money was sent, where dividends came from and which investment platforms or providers may have been used.
Review at least the last 12 months of statements and ideally 24–36 months if available. Older statements can also be useful, particularly for dormant or historic holdings.
When reviewing statements, focus on three things:
Outgoing payments: Look for one-off transfers to investment providers, recurring contributions into ISAs or portfolios and payments labelled “investment”, “ISA”, “broker”, “wealth”, “reinvest” or unfamiliar institution names.
Incoming payments: Look for dividends, sale proceeds, withdrawals from investment accounts or income distributions that may indicate an existing portfolio.
Recurring patterns: Look for repeated payments to the same institution, end-of-tax-year lump sums or irregular withdrawals that may suggest portfolio sales or asset disposals.
What to do:
Highlight every unfamiliar financial institution, search the name to confirm whether it is a broker, platform, registrar or fund manager and create a separate list of probable investment-related institutions to contact later in the process.
Example:
A payment to a known investment provider is a direct lead.
A payment to an unfamiliar institution with “wealth”, “capital” or “investment” in the name should be checked.
This step often reveals accounts even when there is no paperwork at all.
Step 3: Search Email Accounts for Investment Activity
Investment accounts are often fully paperless, which makes email one of the most effective places for asset discovery, platform identification, shareholding evidence and portfolio activity.
Search all inboxes, archived folders and spam or junk folders using investment-related keywords first.
Search for terms such as “annual statement”, “portfolio valuation”, “investment statement”, “ISA statement”, “trade confirmation”, “contract note”, “dividend”, “annual tax certificate”, “capital gains”, “platform fee”, “distribution statement”, “consolidated tax certificate” and “corporate action”.
Also search generic subject lines that are easy to miss, such as “Your statement is ready”, “Your valuation is available” or “Tax certificate available”.
What to do:
Start by searching these document and activity terms across all email folders, then search any provider names already identified through bank transactions, paperwork, tax records or adviser correspondence. Save or note any email that confirms account existence and record the provider name, account or reference number, portfolio valuation, dividend payments and any tax reporting documents.
Example:
An email titled “Your annual statement is ready” may confirm an investment platform even if the person never referred to having investments.
A trade confirmation or contract note confirms that an investment account existed and was actively used.
A dividend notification may reveal a shareholding even where no platform statements are available.
If nothing appears in the main inbox, check:
- older email accounts
- aliases used for financial matters
- archived folders
- spam and junk folders
Investment communications are often automated, infrequent and easy to overlook.
Step 4: Review Documents, Tax Returns and Cloud Storage
Investments often leave a stronger tax and reporting trail than pensions or bank accounts. Even if the account itself is forgotten, tax records may show that it existed.
Start with formal tax records. If the person filed Self Assessment, review SA100 returns, especially dividend income and capital gains sections. Also check for VCT or EIS certificates, which can represent high-value holdings that are easily overlooked.
Then search physical files and cloud storage for evidence such as capital gains summaries, accountant packs, adviser review letters, suitability reports, consolidated tax certificates, ISA certificates and dividend vouchers.
Adviser correspondence can be particularly valuable where investments were held through a discretionary wealth manager rather than a retail platform.
Check likely storage locations including filing cabinets, folders labelled “Tax”, “Investments”, “ISA” or “Shares”, cloud folders such as Google Drive, Dropbox, OneDrive or iCloud and Downloads or Desktop folders on laptops.
What to do:
Build a table recording the provider name, document type, any account reference available, and the relevant tax year.
Use this to identify which providers were active and when and prioritise providers that appear in more than one source.
Example:
A single dividend voucher and a capital gains summary may point to the same investment platform. That is enough to justify contacting the provider.
This step is especially important for older or dormant investment accounts that no longer generate regular email traffic.
Step 5: Check for Direct Shareholdings and Registrars
This step focuses on direct legal ownership of shares held through registrars, rather than investment accounts held through platforms or wrappers such as ISAs, which are covered separately in Step 7.
Not all investments sit inside a modern platform. Some shares may be held directly through company registrars, particularly older holdings acquired outside modern brokerage platforms.
Many people hold shares directly, rather than through a platform. In these cases, shareholder records are usually administered by registrars. In the UK, direct shareholdings are often administered by registrars such as Computershare, Equiniti or Link Group.
Also look for physical documents such as share certificates, dividend statements, dividend cheques, corporate action notices, merger notices or takeover correspondence.
What to do:
Search documents, archived correspondence and email for registrar names or shareholder references. If a registrar appears, contact it to ask whether any holdings are registered under the deceased person’s name and address and gather supporting evidence such as old share certificate numbers, dividend statements or shareholder correspondence before making enquiries.
Example:
A family may assume there were “just some old shares from years ago”, but a registrar letter may reveal an active holding, reinvested dividends or unclaimed proceeds from a historic takeover.
Step 6: Check Devices, Apps and Saved Logins
Many investment accounts now exist only through apps or browser-based logins, which means devices can be an important source of evidence.
Where you have legal access, review phone home screens, app libraries, tablet apps, browser bookmarks, saved passwords in browsers such as Chrome, Safari or Edge and any authenticator apps linked to financial services.
Look for evidence of trading apps, robo-advisers, portfolio trackers, crypto or alternative investment apps and multi-factor authentication entries associated with financial accounts.
What to do:
Make a list of every financial app, login reference or website domain you find. Do not attempt to access accounts without proper authority. Use app names, domains and authentication references as evidence of likely providers and contact those providers formally later in the process.
Example:
If a financial app appears on a device or a provider domain appears in a password manager or authenticator app, that may be sufficient to establish a lead even if no balance or account details are yet known.
This is often one of the fastest ways to identify digital-only investment accounts.
The Financial Conduct Authority also warns consumers to deal only with authorised firms, which makes provider verification an important part of tracing unknown investment accounts.
Step 7: Look for ISAs, General Investment Accounts and Platform Wrappers
This step focuses on investment account wrappers and platform-held accounts, rather than direct shareholdings registered in the investor’s own name, which are covered in Step 5.
Many people do not describe their holdings as “investment accounts”. They refer to them by product name instead, for example an ISA, Stocks and Shares ISA, Junior ISA, savings plan, portfolio or fund account.
That is why it is important to search for product names and account labels, not just the word “investment”.
Search emails and documents for terms such as “Stocks and Shares ISA”, “General Investment Account”, “GIA”, “Junior ISA”, “investment plan”, “fund account” or “portfolio review”.
What to do:
Search all emails and documents for these product names and account labels, cross-reference any matches against bank payments, tax records and provider references already identified and treat each product label as a possible account in its own right.
Example:
Someone may never have described themselves as having “investments”, but may have referred instead to “my ISA”, “my fund account” or “that portfolio I opened years ago”.
Accounts are often hidden by ordinary language rather than missing records. Searching product names helps close that gap.

Step 8: Consider Overseas and Alternative Investments
If the person lived abroad, worked internationally or held assets outside mainstream investment platforms, expand the search beyond UK institutions.
Look for possible overseas or non-standard holdings such as overseas brokerage accounts, foreign bank-linked investment accounts, employee share plans, private company shares, crowdfunding investments, property syndicates, bonds or structured products.
Look for clues in foreign currency transactions, overseas tax records, international addresses, employment contracts or adviser correspondence.
What to do:
Make a separate list of non-UK or non-standard leads, group them by country or institution and investigate each jurisdiction separately, as tracing processes may differ.
Example:
A period working in the US, UAE or Europe may have resulted in a local brokerage account, employee share plan or tax-advantaged investment account that would never appear in a UK-only search.
International investment relationships are often overlooked because they sit outside the domestic financial picture.
Step 9: Contact Providers Directly and Ask the Right Questions
Once you identify a likely provider, act formally. You will usually need a death certificate, proof of identity, proof of authority as executor or administrator, and the deceased’s full name, address history and date of birth.
Do not simply ask whether the person “had an account”. Ask more specific questions such as:
- “Are there any current, historic, dormant or closed accounts under this name?”
- “Are there any ISA, General Investment or share-dealing accounts linked to this person?”
- “Are there any dividend-paying holdings, direct shareholdings or transferred assets?”
- “Can you confirm whether there were closed or transferred accounts in recent years?”
What to do:
Contact each provider on your list, keep a record of who you contacted, when and what they said and follow up where additional documents are requested.
Example:
A provider may say there is “no active portfolio” but still confirm an older transferred ISA, dormant shareholding or a closed account with residual proceeds.
This is often the point where clues become confirmed accounts.
Step 10: Record the Search and Consider Supplementary Tracing Tools
A search becomes much harder if it is not documented. Keep a tracking record showing the provider name, source of the lead, date contacted, outcome and any next action required.
What to do:
Record each enquiry and provider response as the search progresses. Use the log to avoid duplicate enquiries and track follow-ups. If manual searches have been exhausted, consider professional estate asset search services where appropriate.
Example:
If several family members or co-executors are involved, a shared tracking record can help prevent duplicate work and maintain a clear audit trail.
Note on supplementary tools:
Some professional estate search services may help identify certain shareholdings, dormant assets or financial relationships where records are incomplete. These services are not a substitute for provider searches, registrar checks or direct enquiries, but may be relevant in more complex estates.
Why Investment Accounts Are Difficult to Find
The challenge is structural rather than procedural. Investment accounts are often fragmented across multiple providers, may exist only in digital records, can sit inactive for long periods and may involve overseas institutions or cross-border complexity.
In practice, finding investment accounts often depends less on searching a database and more on reconstructing financial behaviour over time.
How Long Does It Take to Find Investment Accounts?
Timeframes vary significantly depending on the complexity of the financial footprint.
Simple cases involving one or two providers and good records may take a few weeks.
Moderately complex cases involving multiple platforms, missing records or partial uncertainty may take several months.
Complex or international cases involving overseas holdings, private assets or partial records may take much longer.
Timing usually depends on the quality of records available, the number of institutions involved and whether digital access or supporting documentation exists.
Final Thought: Fragmentation, Not Disappearance
Investment accounts rarely disappear. They become difficult to find because they are often spread across multiple institutions, poorly documented or simply not visible to family members.
In practice, tracing investment accounts is less a search than a process of financial reconstruction - piecing together records, relationships and clues across providers over time.
The most reliable way to avoid this complexity is to ensure investment accounts are recorded clearly while information is still accessible.

Frequently Asked Questions
How do I find all investment accounts in the UK?
There is no single search. You must combine bank transaction analysis, email searches, document reviews and direct contact with providers.
How do I find forgotten Stocks and Shares ISAs?
Check bank statements, emails and tax documents for references to ISA providers, then contact those providers directly. Stocks and Shares ISAs are usually traced by identifying the provider first, as there is no central register of ISA accounts.
Can I search for investment accounts by name?
No. There is no single system that allows you to search all investment accounts in the UK by name.
Do investment firms contact beneficiaries automatically?
Not in most cases. Providers usually need to be notified and linked to the correct account before assets can be identified or released.
Are investment accounts ever lost permanently?
No. The assets remain with the provider, but they may be difficult to locate without sufficient information.
What is the most effective way to find hidden investments?
Analysing bank transactions is often the most effective starting point, as it reveals transfers to investment platforms and providers.
How do I know if investments existed at all?
Look for indirect evidence such as dividend payments, tax records or references in emails and documents.
Are ISAs included in this process?
Yes. Stocks and Shares ISAs are investment accounts and should be traced in the same way as other portfolios. HM Revenue & Customs sets the tax rules for ISAs, but the holdings themselves remain recorded with the provider, not through a central register.
