Key takeaways
- Almost every UK retail shareholding sits in a pooled nominee. Industry bodies told the Digitisation Taskforce that roughly 99% of the value in FTSE 350 shareholdings is already held that way.
- You hold the beneficial interest and a nominee company holds legal title. Section 126 of the Companies Act 2006 keeps every trust off the register of members.
- If a pooled account is short, the 2011 special administration regulations make every client in that line of stock bear the loss pro rata, and rank the remainder as unsecured.
- At Beaufort the administrators expected some 700 clients to lose more than the compensation cap. The figure the FCA has published since is fewer than 10.
- Direct holding is the exit and it is thin: four sponsors, roughly £400 to £500 a year, and 4,200 individuals on CREST in 2020 against about 50,000 in 2003.
Your broker doesn't own your shares, and your name isn't on the register
If your broker failed tomorrow, whose shares would they be? They'd be yours — and you have never been their legal owner.
Almost every UK dealing account, ISA and SIPP holds shares through a nominee company. That's a company the broker controls whose only function is to be the registered holder of client assets. Its name goes on the company's share register. Yours goes on the broker's internal records.
English law splits ownership in two here. The nominee holds legal title. You hold the beneficial interest — the dividends, the sale proceeds, and the right to direct what happens to the shares. The Law Commission's 2020 scoping paper on intermediated securities says it without hedging. Its words: "when you hold your investments through an intermediary, such as a broker, online investment platform or a bank, you are not the legal owner of your investments".
That split does most of the work you'd want it to do. Assets held for you sit outside the broker's own estate, so its creditors can't reach them. The complication is the account they sit in. Your shares are usually held in one pooled account alongside every other client's, and pooling is what decides who carries the loss when the pool comes up short.
The FCA rule that puts a nominee company between you and the register
The structure is written into the FCA's custody rules, in chapter 6 of the client assets sourcebook. The rule on registration of legal title gives a firm four options in order of preference. The first is the client's own name. The second is the one the market actually uses: "a nominee company which is controlled by" the firm, an affiliated company, a recognised investment exchange, or a third party the assets are deposited with.
The FCA then closes the gap that creates. A firm "must accept the same level of responsibility to its client for any nominee company controlled by the firm" as it accepts for itself. The purpose is stated in the same chapter. The rules exist to "restrict the commingling of client and the firm's assets", and to stop client assets "being treated as the firm's assets in the event of its insolvency".
Company law then keeps you off the register whatever the FCA wants. Section 126 of the Companies Act 2006 runs to a single sentence: "No notice of any trust, expressed, implied or constructive, shall be entered on the register of members of a company registered in England and Wales or Northern Ireland, or be receivable by the registrar". The registrar records the nominee. It records nothing about who the nominee holds for.
So the register is accurate and useless at the same time. It names the legal owner correctly, and it's the wrong document to search if you're looking for yourself.
Pooling is what turns one firm's shortfall into everybody's
The account your shares sit in is an omnibus account. The Law Commission's glossary is blunt about what that means: "An account which is used to hold the securities of more than one investor". The same entry adds: "Also known as a 'pooled account' or a 'nominee account'". Most intermediated securities are held this way. A shortfall, in the same glossary, is what happens when an intermediary "does not have sufficient securities in an omnibus account to satisfy claims made by its account holders".
While a firm is trading, the rules try to make a shortfall the firm's problem. Custody records have to be checked against the firm's own ledgers and against the third party's records, with no more than one month between checks. Where a discrepancy leaves an unresolved shortfall, the firm must "appropriate a sufficient number of its own applicable assets to cover the value of the shortfall". It then holds those assets for the affected clients.
That rule stops working at the moment you'd most want it. The Law Commission notes that it "is not primarily intended for insolvency scenarios", and that a failed firm is relieved of it where the insolvency procedure prevents compliance. The chain doesn't help either: no other intermediary is obliged to make good a shortfall created by one above it.
What happens instead is set out in the Investment Bank Special Administration Regulations 2011. Where an administrator finds a shortfall in a client omnibus account that can't be remedied, the rule is proportionate. The shortfall must "be borne pro rata by all clients for whom the investment bank holds securities of that particular description in that same account". The division runs "in proportion to their beneficial interest in those securities". The part you don't get back becomes a shortfall claim, and that claim "shall rank as an unsecured claim". Unsecured, in a failed broker, is a polite way of describing the back of the queue.
Cash is handled more firmly than stock. Client money sits under a statutory trust and pools on the firm's failure, with each client receiving "a sum which is rateable to the client money entitlement". On the asset side, the Law Commission's observation is flat: "There is no equivalent statutory trust or distribution rules for intermediated securities".
Beaufort: the pool was almost intact, and the costs still came out of it
The clearest UK test of all this is Beaufort. The FCA placed Beaufort Securities into administration and Beaufort Asset Clearing Services into special administration on 1 March 2018.
The administrators found a large book and a largely intact pool. Their April 2018 proposals record "about 29,500 clients of which approximately 60% had Client Money or Client Assets holdings". They also record 15,000 clients holding one or more lines of stock, and an independent valuation of the custody assets "at around £500 million". The FCA puts the return programme at "approximately 17,500 retail and corporate clients". The chart plots that funnel, from the client book down to the group the administrators expected to absorb a real loss.
Then the bill arrived. The costs of returning client assets were charged against the client assets themselves. The FSCS agreed to cover 94% of them. As for the rest, the FCA's account is that "Most of the remaining 6% of costs will be borne by corporate clients". For custody assets the deduction was "a flat fee, where maximum costs are capped at £10,000 per client account". For client money it was a percentage of each balance, capped at 10%.
That is the part people find surprising. The shares were there. The loss came from the cost of handing them back, and it was taken out of property held for clients rather than out of the firm's estate. The transfer plan also covered roughly 10,000 clients "whilst retaining and preserving their ISA and pension status". That is worth knowing if you assume a wrapper travels automatically, and our guide to the ISA rules on flexibility, transfers and death covers where it doesn't.
The two published estimates of who ended up out of pocket disagree, and the gap is instructive. In April 2018 the administrators thought "some 700 Clients with Client Portfolios valued in excess of £150,000 (per Client) may suffer shortfalls in recovery of their entitlements in excess of the FSCS £50,000 compensation limit". The FCA's page, maintained since, records "a small number of retail clients (fewer than 10)" in that position, alongside 99.7% of client money and 99% of client assets returned. The early figure was a worst case struck before the cost-sharing deal with the FSCS; the later one is the outcome. Beaufort was capped at the old £50,000 limit, and the current limits are set out in our guide to FSCS protection for deposits and investments.
Voting and corporate actions reach you through the chain, or not at all
Company law gives rights to members, and the member is the nominee. The Law Commission's summary of what that leaves you is a list of absences. An ultimate investor generally "cannot exercise the right to vote in relation to their investments". Where an intermediary does facilitate voting, investors "find it difficult to confirm that their vote was received and counted by the company". They are "not entitled to attend meetings of the company or receive information from the company". And they "cannot be easily identified by a company which wants to engage with its ultimate investors".
Behind that sits the "no look through" principle. In Secure Capital SA v Credit Suisse AG, Lord Justice David Richards described it plainly. "The system operates on the basis of a 'no look through' principle, whereby each party has rights only against their own counterparty". You have a claim against your broker. You don't have one against the custodian above it, or against the company whose shares you thought you owned.
Voting isn't impossible from inside the chain. The Law Commission sets out five mechanisms "by which an ultimate investor may be able to vote on a resolution, without becoming a ‘member’", starting with the intermediary appointing you as its proxy. What none of them creates is an entitlement. The Digitisation Taskforce's final report of July 2025 wants that changed. It proposes a "Bill of Shareholder Rights" and a mandatory baseline service. Intermediaries would be required to identify you to the company, pass its communications down the chain and send your instructions back up. The report's comparison table shows certificated shareholders and nominee holders with the same six rights: voting, dividends, information, inspection, suing for wrongdoing, and participating in corporate actions. That table describes the position after the recommendations are implemented, not the position now.
The three ways out, and what each of them costs
The first is a paper certificate with your name on the register. It's a shrinking option with a deadline attached. The Taskforce found that "nearly 50% of certificated shares in the UK (average holding value £4,500) are in just five companies". It recommends replacing paper certificates with digitised registers by the end of 2027.
The second is a personal CREST account, where you're the member on the register and an intermediary sponsors you into the settlement system. It works, and hardly anyone uses it. The Law Commission was told there were four intermediaries offering personal CREST accounts, "with approximate annual fees between £400 and £500". The number of individuals holding directly through CREST "has decreased from approximately 50,000 members in 2003 to 4,200 members in 2020", and their holdings on the system totalled £1.3 billion in April 2018. A flat £400 is a different shape of cost from a percentage charge on your portfolio. The crossover arithmetic is the subject of our guide to where a flat platform fee overtakes a percentage.
The third is a designated or segregated nominee, an account holding one investor's assets rather than many. It removes the feature that makes pooling uncomfortable: you're no longer sharing a shortfall with strangers. It also removes the feature that makes pooling comfortable. The Law Commission's note on the point is short and cold. Where an intermediary holds client assets in a single client account "and those assets are lost, then the starting point is that the client sustains the entirety of the loss". Pro rata sharing runs in both directions, and a designated account opts you out of both.
The strongest objection comes from the body that reviewed the system
The counter-case for pooled nominees is better than the complaints suggest, and the best version of it is the Law Commission's own. After a full call for evidence it declined to recommend dismantling intermediation, on the view that "there is not a realistic alternative system of holding investments". Its preferred route was to keep the current structure and fix specific defects, which it called "a proportionate response to the issues identified in this paper".
Two things support that. Pooling is how the market clears. Industry bodies told the Taskforce that "approximately 99% of the value in shareholdings in the FTSE 350 are currently held" through the intermediated chain, and called it "globally accepted best practice". And the rights people say they lose are largely rights they weren't exercising. The Taskforce records that even the individual shareholders who preferred direct ownership "accepted that exercise of voting rights in practice was limited".
Beaufort is evidence for the defence too. 99.7% of client money and 99% of client assets came back to clients. The structure did what it was built to do. What it didn't do was make the process free.
What this evidence can't settle
Three limitations are worth stating. The first is that the numbers on direct holding are old and thin. The 4,200 CREST members and the £400 to £500 fee range are what the Law Commission was told in 2020, not the result of a survey. The paper also notes those fees had already risen sharply.
The second is that Beaufort is a single sample, and a flattering one. The pool was nearly intact, so the loss was a cost-allocation problem rather than a missing-assets problem. A failure where client stock had genuinely gone would test the pro rata rule properly, and Beaufort can't tell you how that goes.
The third is jurisdiction. All of this is English law, an FCA rulebook and a UK insolvency regime. The Law Commission notes that the US scheme under the Securities Investor Protection Act "provides priority to the claims of ultimate investors in the event of intermediary insolvency". Its trustee can also buy securities to satisfy those claims, and consultees referred to "the perceived superiority" of that scheme. Scots law differs again: there, "beneficial interest" denotes "a personal right against the obligant rather than a proprietary interest in any form".
What would change the conclusion
If the Taskforce's baseline service becomes law, the ownership question stays exactly where it is and the rights question narrows. Intermediaries would be obliged to identify you to the company, pass on its communications and facilitate your vote, which is most of what a place on the register used to buy you.
If dematerialisation finishes on the Taskforce's timetable, the alternatives shrink instead. Paper certificates end by 2027 under the first step, and the second step moves everyone into the intermediated chain — which turns the nominee from the default structure into the only one.
And if a UK broker fails with a genuinely empty pool, the pro rata rule stops being theory. The number that matters then isn't the value of your portfolio. It's the size of the shortfall in the particular line of stock you hold. That is what the regulations divide up in proportion to beneficial interest, and the remainder ranks as an unsecured claim rather than a loss somebody else makes good.
Which points at the document that actually decides your position, and it isn't the FCA handbook. It's your broker's terms. The Law Commission found that an intermediary's standard terms "will usually provide that any shortfall in intermediated securities held in an omnibus account is to be suffered proportionately by ultimate investors". That is a clause carrying a great deal of weight in an agreement most people have never opened.
