Key Takeaways
- Take prompt action if you suspect professional negligence. Limitation periods can expire much earlier than you expect, leaving you unable to claim.
- The primary limitation period for professional negligence claims is six years from when you first suffered actual loss, not from when you realise something went wrong.
- If you only discover the possible negligence later, you may have up to three extra years from your “date of knowledge” under section 14A of the Limitation Act 1980, but the rules are strict.
- Courts treat the “limitation clock” as starting when you entered into a flawed transaction or suffered measurable financial loss, not when the damage is finally quantified or future consequences become clear.
- Delaying your claim can be fatal. If you wait “to be sure” instead of seeking advice early, your claim could be struck out for being time-barred.
- Standstill agreements can give extra time but will not save your claim if you miss court deadlines or wait too long to investigate the problem.
- You do not need to prove your adviser was negligent before the limitation period starts. It is enough to know something has gone seriously wrong and that the adviser may be at fault.
- If you do nothing and miss the limitation period, your right to claim professional negligence compensation will be lost forever, no matter how strong your case was.
£74 Million Professional Negligence Claim Struck Out: When Does the Limitation Clock Start in England and Wales?
It can come as a shock. Even a £74 million claim with clear evidence of professional negligence can be struck out before trial, simply because the claimant waited too long. In Three R Tourism and Hospitality Ltd & Ors v Orrick Herrington & Sutcliffe (UK) LLP [2026] EWHC 1844 (KB), the High Court ruled that the limitation clock had started years earlier than the claimants realised. The result? Their entire action was out of time, regardless of how strong the allegations seemed.
Most people assume the limitation period for professional negligence starts when loss becomes obvious or when you finally discover the bad advice. English law is much stricter. In reality, the limitation period usually starts running when you first suffer real economic loss, often as soon as you enter a flawed transaction or take an irreversible financial hit. You do not need full proof of negligence. It is enough to know something has gone seriously wrong. Waiting until all consequences emerge, or until you feel certain, is a costly mistake.
Using Three R Tourism as a detailed case study, this article explains exactly how and when professional negligence limitation periods begin under English law. We set out the six-year rule, the three-year “date of knowledge” extension under section 14A of the Limitation Act 1980, and how courts decide when time starts to run. If you are concerned about missed deadlines or want to protect your commercial claim, our London-based solicitors will assess your position quickly and decisively.
The Case: Three R Tourism v Orrick [2026] EWHC 1844 (KB)
Background
- Claimants: Three R Tourism & Hospitality Ltd and its two founders.
- Defendant: Orrick Herrington & Sutcliffe (UK) LLP.
- The deal: Orrick advised on a £40 million private equity restructuring and investment by the Carlyle Group in November 2018. The result:
- The claimants’ 52.7% stake in an online travel business was transferred into Carlyle’s control.
- The claimants retained only 10,000 ordinary shares while Carlyle took 40 million convertible preference shares with a 12% annual compounding dividend and the right to convert if financial targets were missed.
- Crucially, if the business underperformed, Carlyle could dilute the claimants’ shareholding to near zero.
- The claimants took on $20.5 million in debt, solely their liability.
- No contractual protection existed for the founders’ employment.
What Went Wrong
- October 2019: The founders were dismissed without notice.
- January 2020: Carlyle exercised conversion. The claimants lost their entire shareholding for nominal value and were left with $28.4 million in debts.
The Negligence Claim
The claimants alleged Orrick failed to warn them the deal was toxic and favoured Carlyle, didn’t explain the conversion mechanism or dilution risk, failed to highlight the “suicidal” debt burden, and didn’t protect employment rights. Their total claim was $74 million.
The Limitation Defence
- October 2024: A standstill agreement extended the deadline to issue proceedings to 30 May 2025.
- 30 May 2025: The claimants issued a claim within the standstill, but failed to serve it within the required 4 months.
- 18 November 2025: A second claim was issued, but by then the limitation period had expired.
Orrick argued that the six-year limitation ran from the agreements’ signing in November 2018, expiring by November 2024. Allowing for the standstill, the cutoff was June 2025, so the November 2025 claim was five months too late.
Claimants’ Arguments
- No actionable damage until January 2020 (the loss didn’t crystallise until the forced conversion).
- No knowledge until September 2022, when a letter from Clifford Chance finally made clear the legal structure was the problem and Orrick’s advice may have been at fault.
The Judgment: Mr Justice Cotter
- Actionable Damage: The court rejected the delay argument. Drawing on Nykredit v Erdman, Law Society v Sephton, and Axa Insurance v Akther & Darby, Cotter J held the claimants suffered immediate, measurable economic loss when they entered the flawed agreements in November 2018. They were “financially worse off” from day one, having exchanged a valuable shareholding for “largely paper consideration” and significant non-contingent debts. Even if final losses depended on future outcomes, the wrong transaction itself caused real damage.
- Section 14A Limitation Act 1980 – Constructive Knowledge: The court ruled that the three-year fallback period under section 14A was also long expired. By at least January 2020, when the catastrophic loss became clear, the claimants knew or should have known things had “gone very badly awry.” A reasonable person in their position would have investigated Orrick’s advice. The two-year delay before consulting solicitors was “baffling” and relying on late knowledge “unrealistic.”
- Outcome: The claim was struck out. Limitation had long passed. There was no realistic case the claim was not statute-barred.

Understanding Limitation in Professional Negligence Claims
The Primary Rule: Six Years from When Damage Occurs
The Limitation Act 1980 sets out the following headline rules:
- Tort (negligence): Six years from when actual economic damage is suffered (section 2).
- Contract: Six years from breach (often when the flawed advice or omission happened).
In professional negligence, the “damage” isn’t when you first notice the problem, or when the full loss eventually hits. It’s when you suffer marked, measurable economic loss—often when you enter a damaging transaction or incur liability.
“Actionable Damage” vs “Contingent Liability”
Courts draw a critical distinction (as in Three R Tourism):
- Actionable Damage: Immediate real loss at the time of the adviser’s error—such as acquiring bad assets, being exposed to enforceable debts, or giving up valuable rights. Uncertainty about the final impact does not delay the clock.
- Contingent Liability: No real loss yet, only the risk of loss in future. For example, a client may have a professional fail to warn about potential tax liability, but until HMRC acts and the liability bites, no actual loss has occurred.
The Safety Net: Section 14A—Three Years from “Date of Knowledge”
Section 14A Limitation Act 1980 is a crucial fallback. If you only discover later that you suffered damage attributable to your adviser, you may have three years from when you knew or ought to have known of the key facts.
- Actual Knowledge: When you personally became aware that you suffered significant loss linked to the adviser’s act or omission.
- Constructive Knowledge: What a reasonable person in your position, acting promptly and sensibly, would have found out through reasonable investigation, including seeking expert advice.
Courts interpret this strictly and look at when a reasonable businessperson would have suspected and acted.
Standstill Agreements: Useful, but Not Bulletproof
A standstill agreement “pauses” limitation, buying time for negotiation or investigation. But:
- You must issue your claim before the agreed extended deadline.
- Once issued, the claim form must be served within four months unless the court extends this before time expires.
- Issuing a new claim out of time (for example, because the first was not served in time) won’t bypass limitation.
Common Limitation Pitfalls in Professional Negligence Claims
Some of the most frequent errors in professional negligence limitation are:
- Waiting for Certainty: Hoping to be sure the adviser was negligent or to quantify loss before seeking legal advice. Delay means evidence goes stale and claims can run out of time.
- Assuming Limitation Runs When the Loss Crystallises: In most flawed transaction cases, time starts running when you sign up or the deal is done, not when later disaster strikes.
- Not Investigating After Obvious Catastrophe: If you lose control of your business or are left saddled with debts, courts expect you to investigate promptly, especially if you had professional advisers to protect you.
- Issuing but Not Serving the Claim in Time: Issuing a claim within limitation is not enough. You must serve it within the procedural timeframe. Failing this, a fresh claim issued after time expires is usually struck out.
- Mis-identifying the Cause: If you think your losses are only commercial bad luck or blame another party (as in Three R Tourism), but the root lies in adviser’s drafting or review, you must still act.
- Misunderstanding the Longstop: The fifteen-year period under section 14B only applies where the claim was truly undiscoverable earlier. Courts are sceptical of claimants who wait years after disaster.
- Overlooking Early Damage: Damage begins even if you hope for a better outcome or haven’t yet lost money; entering a disadvantageous deal is enough.
What to Do If You Suspect Professional Negligence
Act immediately.
As soon as you suspect something has gone wrong—be it a deal failing, an unexpected loss, or a legal outcome opposite to your adviser’s assurances—seek legal advice without delay. You do not need full proof, only grounds for concern.
To protect your limitation position:
- Record key dates: When the advice was received; when the transaction occurred; when you first realised a loss; when you suspected a negligent act.
- Gather documents: Advice letters, contracts, emails, transaction paperwork, and evidence of loss.
- Seek urgent legal input: Protective action, such as issuing a claim, may be necessary even if investigations continue.
- Consider standstill agreements: These can pause limitation, but only before time expires, and they don’t forgive missed procedural steps.
- Use a specialist. Professional negligence limitation analysis is complex and error-prone. Generalist or DIY approaches are highly risky.

Frequently Asked Questions
Can I bring a professional negligence claim if I only recently discovered the problem?
Possibly, if the three-year “date of knowledge” period under section 14A of the Limitation Act 1980 has not already expired. However, limitation may run from when you suffered economic loss, not when you realised the issue. Courts apply a mainly objective test. Early legal advice is essential to check your position.
What is the difference between limitation in contract and limitation in negligence?
Limitation in contract generally runs from the breach date, while in tort (negligence) it runs from when you suffer actionable loss. Both usually have six-year periods (Limitation Act 1980, section 2 for tort).
How do I work out when my limitation period starts?
Focus on when real, measurable financial loss happened—such as entering an unfavourable agreement, acquiring liabilities, or losing vital rights. Limitation assessment is fact-specific and benefits from early specialist input.
Can I use a standstill agreement to get more time?
Yes, when negotiated before limitation expires, but it won’t cure procedural missteps, such as failing to serve a claim form on time. Handle them with care and seek experienced legal support.
What if the professional concealed their mistake or committed fraud?
There can be extra time under the Limitation Act 1980 if fraud or deliberate concealment is proved, but these exceptions are complex and rare. Take advice immediately if you suspect this.
Do special rules apply for minors or people lacking mental capacity?
Yes. Under section 28 of the Limitation Act 1980, time does not start to run for those under 18 or lacking capacity until they turn 18 or regain capacity.
What counts as “actual loss” in a professional negligence claim?
Actual loss arises where you are left financially worse off—taking on unwanted liabilities, losing value in shares, or relinquishing key rights—even if later losses arise.
Can I claim after more than 15 years?
No. Section 14B of the Limitation Act 1980 imposes a 15-year absolute deadline for most professional negligence claims.
When should I issue protective proceedings?
If you are close to a deadline or unsure if limitation may be expiring, issue proceedings promptly. Standstills can help, but only if properly agreed and before the time limit.
What happens if I am late?
The other side can apply to strike out your claim. The court will likely dismiss it unless an exceptional statutory exception applies.
Conclusion
Three R Tourism v Orrick shows that even a $74 million negligence claim with apparently strong prospects can be lost entirely on limitation. The rules are uncompromising:
- Limitation usually runs from the date of the flawed transaction, not when final loss occurs.
- Courts fix you with “knowledge” when a reasonable person would have investigated, not when you actually realised there was a problem.
- Judges are strict and unsympathetic to long delays. The concept of constructive knowledge is mainly objective.
The judge called a two-year delay before seeking legal advice “baffling” and relying on late discovery “unrealistic”.
If you suspect professional negligence, do not wait. Early action gives your claim the best possible chance.
