One minute you are deciding who to take on your prize holiday. The next, another email arrives: “Unfortunately, our previous message was sent in error. Please accept our apologies.”
Can the organiser simply undo the win?
Sometimes a mistaken notification can be corrected. But “technical error” is not a complete legal explanation, and an apology does not automatically resolve everything that happened after the message arrived. Equally, a congratulatory email does not invariably entitle its recipient to the advertised prize. The original rules, the nature of the mistake and the legal obligations matter.
There are three questions worth keeping separate: were you misled, were you actually entitled to the prize, and did you suffer a financial loss because you reasonably acted on what you were told?
The first can support an advertising complaint without automatically answering the other two.

The Zavvi ruling: an apology did not erase the misleading message
In October 2019, the ASA upheld a complaint about a Zavvi promotion offering a VIP trip for two to the Champions League final in Madrid.
Fifty-seven complainants had received an email saying they had won, followed by a correction. Zavvi explained that its email platform had linked the winner notification to its entire opted-in marketing database rather than the single selected winner.
The email was personally addressed and unambiguous about the supposed win.
Zavvi said it acted within hours, contacted the genuine winner, issued corrections and offered affected recipients a 15% discount code. Nevertheless, the ASA found that telling people they had won when they had not gave them justified grounds for complaint and breached the promotional rules (ASA, 2019).
The ruling did not order Zavvi to send every email recipient to Madrid. Its action concerned the administration of future promotions, not a determination of each recipient’s contractual entitlement.
That distinction is important: an organiser can have handled a promotion badly even where the eventual remedy is not another copy of the top prize.
Read the whole message, not just “congratulations”
Before challenging a retraction, put the original terms beside the complete notification. A subject line can create one impression while the body explains a different stage in the process.
These hypothetical messages are not interchangeable:
| What the message says | What needs checking |
|---|---|
| “You have been shortlisted.” | Has a final selection actually taken place? |
| “You have been selected, subject to the eligibility checks in the competition terms.” | Which original checks remain outstanding, and what do they require? |
| “Your eligibility has been verified. We confirm that you have won the holiday described below.” | What basis does the organiser now give for withdrawing that confirmation? |
| “Your prize is confirmed. Please arrange your travel for the agreed date.” | What arrangements did the organiser invite you to make, and did you act on that invitation? |
This does not mean a qualification buried anywhere in the paperwork automatically cures a misleading headline. CAP requires promoters to avoid confusion about prizes and communicate significant conditions, including eligibility restrictions (CAP Code, accessed September 2026).
But a clearly explained provisional selection is different from a completed verification.
If an original, properly disclosed age restriction excludes you, an email expressly subject to that check is not equivalent to an unconditional confirmation. Conversely, the organiser should not invent an eligibility condition after discovering that it would prefer another winner. CAP guidance treats changes to entry conditions as exceptional, not routine housekeeping (ASA/CAP, 2026).
Ask what the mistake actually was
“An administrative error occurred” describes a category of problem. It does not explain yours.
I would ask the organiser to distinguish between:
A sending error: a correctly conducted draw produced one winner, but the notification went to someone else or an entire mailing list.
A selection error: the wrong entry list, duplicated entries or an incorrect process affected who was chosen.
A display error: a screen or template showed the wrong prize or amount.
A failed eligibility check: someone was selected but did not satisfy an original condition.
The evidence needed to assess each is different. A mailing-list error does not necessarily mean the draw itself was rigged. A properly conducted draw does not establish that every person accidentally emailed was selected.
There is another distinction worth pressing. “You never won” and “you won, but our supplier can no longer provide the prize” are different explanations. CAP requires promoters to award advertised prizes or reasonable equivalents; an inability to source an item should not be casually relabelled as a mistaken notification (CAP Code, accessed September 2026).
A useful question is:
Are you saying that I was never selected, that my selection was invalid under an original condition, or that you cannot now fulfil a valid win?
Technical errors have produced different results in court
Two court decisions illustrate why “the screen said I won” and “our system made a mistake” are both incomplete arguments.
These were paid online-gambling cases, not decisions about ordinary free-giveaway emails. Their relevance is how carefully the courts examined the actual messages and contractual rules.
When the claim to the larger prize failed
In Parker-Grennan v Camelot, decided by the Court of Appeal in March 2024, a player claimed £1 million after an online instant-win game displayed additional matching numbers.
However, the game’s congratulations message identified a £10 win, and its final outcome credited £10. The larger matching pair resulted from an error in the animation, rather than the system selecting a £1 million prize.
The court examined the applicable rules and procedures and rejected the claim to £1 million (Court of Appeal, 2024).
It would therefore be misleading to summarise this as “the operator unequivocally confirmed a million-pound win and was allowed to take it back”. The conflicting parts of the display and the rules were central.
When the error argument did not defeat the claim
In Durber v PPB Entertainment, the High Court reached a different outcome in March 2025.
The game showed the player that she had won its “Monster Jackpot”, but Paddy Power paid the much smaller “Daily Jackpot”, blaming a mapping error affecting the animation.
The court found that the game rules entitled her to the larger jackpot. The error provisions relied upon did not protect the operator: the judgment addressed their interpretation, whether they formed part of the contract and their fairness. The winning claimant’s barristers provide a first-hand account of the decision (Twenty Essex, 2025).
The lesson is not that one case cancels out the other. Different wording, rules and circumstances can produce different outcomes. Neither an error label nor a screenshot should replace that analysis.
Does replying “I accept” make the win binding?
Do not rely on it as a magic formula.
An adviser would need to establish whether there was an enforceable prize promise, what conditions governed it and what the notification added. That is not necessarily decided by who sent the last email.
In England and Wales, contract formation ordinarily requires an offer, acceptance, an intention to create legal obligations and consideration — something given or done in exchange. Consideration need not be money. Consequently, free entry does not automatically mean there can be no contractual obligation, but neither does every free promotional message create one. Scots law differs because consideration is not essential to forming a contract (Chartered Trading Standards Institute, 2026).
For a valuable disputed win, the documents need examining as a whole. “I accepted before they corrected it” is a fact worth recording, not a guaranteed winning argument.
An error clause needs scrutiny too
A term allowing genuine mistakes to be corrected is not automatically invalid. Its scope, prominence and fairness still matter.
Where the Consumer Rights Act applies, unfair consumer-contract terms and consumer notices are not binding on the consumer. Simply pointing to an error disclaimer does not settle whether it is enforceable or covers the particular problem (Consumer Rights Act 2015, section 62).
Ask for the original clause relied upon and an explanation of its application. A new website notice saying “all notifications may be cancelled” does not tell you what governed your entry.
Timing matters — but it is not a stopwatch contest
There is no useful rule of thumb that an organiser “has 24 hours to take it back”, or that waiting two days automatically makes a win irreversible.
Instead, build a timeline showing when the message was sent, when the organiser says it discovered the mistake, when it told you and what happened in between.
Consider three hypothetical versions of a concert-ticket promotion. In each, travel and accommodation are the winner’s responsibility.
The correction arrives seven minutes later
A winning email arrives at 9am. At 9.07am, the organiser corrects it. You have told your partner but have not spent anything.
There may still be an advertising complaint about the false notification. However, there is no train fare or hotel booking to reimburse in this example. Whether the prize was legally owed remains a separate question.
You book before an expressly required check
The email says selection is provisional until residency is verified. Before completing that step, you book non-refundable travel.
The original terms clearly exclude residents outside the eligible area, and you do not qualify.
I would expect the outstanding check to feature prominently in any assessment of your reliance. That is a materially different position from someone booking after the organiser expressly confirmed that all requirements were satisfied.
A person checks your details and tells you to proceed
You query the initial notification. The organiser checks your details, confirms your eligibility and tells you in writing that the tickets are yours. You ask whether to book travel, and it confirms the event date and says to proceed.
Only after you book does it explain that someone selected the wrong spreadsheet row.
Here, the follow-up correspondence deserves at least as much attention as the original automated email. You have evidence that you checked before committing money, and that the organiser knew what you intended to do.
These examples are not predetermined legal outcomes. They show why the sequence of confirmations and expenditure matters more than the bare number of hours before the apology.
What does “I relied on the message” actually mean?
In an everyday sense, it means that you changed your position because you believed what the organiser told you. You booked a train, paid a deposit or arranged unpaid leave.
Legally, spending money is not enough by itself. A claim needs an appropriate basis: for example, breach of an enforceable contractual obligation, or liability for a careless statement where the necessary duty and other requirements are established.
The Supreme Court has emphasised that liability for careless information causing financial loss involves questions about responsibility, reasonable reliance and whether that reliance should have been foreseen. Its decision in Steel v NRAM was not a competition case, but it illustrates why “the email was wrong and I acted on it” is not the entire legal test (UK Supreme Court, 2018).
For a prize dispute, useful evidence includes what the organiser knew you were planning, whether it encouraged the expenditure, whether the cost was connected with using the prize and whether anything should have prompted further checking.
Spending money does not turn you into the valid winner. Not spending money does not destroy an entitlement to a prize that was already legally owed.
Separate the prize from the wasted costs
Suppose our hypothetical concert winner paid:
| Expenditure | Paid | Refund obtained | Amount still lost |
|---|---|---|---|
| Train tickets | £120 | £35 | £85 |
| Hotel booking | £150 | £150 | £0 |
| Total | £270 | £185 | £85 |
The remaining out-of-pocket loss is £85, not £270.
That does not establish that £85 is legally recoverable. It establishes the amount requiring explanation and assessment. Keep the booking confirmations, cancellation terms and refund evidence.
My practical recommendation is to pursue available refunds promptly and stop making further commitments once the win is disputed. Do not spend more in the hope of strengthening the claim.
Tell the organiser that you are reducing possible losses without agreeing that its withdrawal was justified. Ask it to assess the prize entitlement and outstanding expenses separately, while avoiding overlapping claims for the same loss.
Also be precise about leave from work. “I booked annual leave” does not necessarily mean “I lost wages”. If leave was unpaid, preserve the evidence rather than attaching a guessed daily rate to the complaint.
Ask for an explanation you can actually assess
Keep the original email, not just a cropped screenshot. Save the sender details, time, full wording, attachments and any claim form it linked to.
Alongside it, retain the original competition terms, your entry evidence, subsequent personal confirmations, the correction and any financial records.
Then ask the promoter to explain the specific error and preserve the relevant records. You do not need another entrant’s address or identity documents. A clear explanation of the selection and notification process is the point.
I would particularly want answers to these questions:
Was I ever selected as a winner under the original process? What exactly failed? When was the mistake discovered? Why were any later confirmations given? Which original condition permits the action now proposed?
“Human error” may be true. It still leaves room for a substantive explanation.
A complaint you can adapt
Subject: Withdrawal of confirmed prize — [competition/reference]
On [date], you notified me that I had won [prize]. The message stated “[relevant wording]”.
I completed [required claim or verification steps]. You subsequently confirmed [details, where applicable].
On [date], you told me that the notification was a mistake and withdrew the prize.
Please explain what went wrong, whether I was selected under the original competition process, when the error was discovered and which original condition you rely upon.
I ask you to review whether the prize remains due under the original terms and your subsequent communications. Please preserve the relevant selection, notification and verification records.
[Where applicable: Before receiving the correction, I incurred the attached costs after relying on your confirmation. I have obtained or requested available refunds. My remaining documented loss is £[amount]. Please address this separately from the question of prize entitlement.]
My requested resolution is [state it]. If you reject that request, please provide your reasons and identify any independent dispute-resolution process available.
Please respond by [reasonable date].
Kind regards,
[Name]
This is an initial complaint, not a formal letter before legal proceedings. Include only events and costs you can substantiate.
An apology, compensation and a prize are different outcomes
An apology acknowledges the mistake. A discount code may be goodwill. Reimbursement may address expenditure. Supplying the prize may fulfil an existing obligation or form part of an agreed settlement.
Do not let those possibilities become muddled.
Where the organiser offers something, ask whether it is simply a goodwill gesture or a proposed settlement of every issue. Read any “full and final” wording before agreeing, particularly where the prize or outstanding costs are substantial.
The ASA accepts complaints about unfairly administered promotions, but its sanctions concern advertising compliance. An upheld ruling is not an individual court order awarding the prize or compensation (ASA, accessed September 2026) (ASA, accessed September 2026).
For an enforceable personal remedy, get advice on the legal basis, evidence, correct defendant and likely costs before pursuing a civil claim. The advertised prize value is not automatically the amount a court would award merely because the notification was misleading (Citizens Advice, accessed September 2026) (Chartered Trading Standards Institute, accessed September 2026).
A correction should explain more than “sorry”
Nobody can make an email system incapable of error. That does not mean the consequences should automatically fall on the recipient.
The strongest response is to establish what you were promised, what conditions remained, what actually went wrong and what you did before you were told.
Sometimes the evidence will support a correction without entitlement to the prize. Sometimes the organiser may still owe the prize. Sometimes the important unresolved issue will be expenditure incurred after a convincing, personally confirmed notification.
“The email was a mistake” explains why the organiser wants to retract it. It does not, on its own, settle what it owes you.
