Limitation Periods for Professional Negligence Claims
Quick fact
In England and Wales, the usual limitation period for professional negligence is six years from the date the cause of action accrues, but for latent damage (damage that is not immediately discoverable) there is a special extension to three years from the 'date of knowledge', subject to a long stop of fifteen years from the negligent act or omission.

You hire an accountant who makes an error that costs you tens of thousands of pounds. You don't discover it until seven years later. Is it too late to sue? The answer might surprise you.

Understanding Limitation Periods for Professional Negligence Claims
Imagine you're in a race, but the starting gun fires at different times depending on the situation. Limitation periods are legal deadlines for bringing a claim. The fundamental idea is that you must start legal proceedings within a certain time after the wrongful act or after you discover the damage. For professional negligence, the clock usually starts when the negligent act causes damage, which often happens at the same time as the act itself. But what if the damage is hidden? For example, a structural engineer's faulty design might not cause a visible crack for years. In such cases, the law provides a special rule: the clock starts when you actually knew, or reasonably should have known, about the damage. This 'date of knowledge' extends the time limit, but not indefinitely—there's a maximum of fifteen years. This ensures that professionals aren't exposed to claims forever, while still giving claimants a fair chance.
A deeper explanation
The mechanism of limitation periods balances two competing interests: the claimant's right to seek redress and the defendant's need for certainty and finality. The primary rule is that you have six years from the date the cause of action accrues. In professional negligence, this is often the date the negligent advice was acted upon, leading to loss. However, the law recognizes that some damage is hidden—latent. The Limitation Act 1980, Section 14A, provides a special extension for such cases: you have three years from the date you first knew (or ought to have known) the facts that would make a reasonable person consider the damage significant enough to investigate. This 'date of knowledge' is a subjective-objective test: what you actually knew and what you should have known. There's also a long stop: no claim can be brought more than fifteen years after the negligent act or omission, regardless of when you discovered it. This is crucial for professional indemnity insurers who need to price risk. The courts also have discretion to extend the period under section 33 for personal injury cases, but that discretion is not available for pure economic loss. Understanding these rules is vital for professionals and their insurers, and for claimants who must act swiftly once they are on notice of potential claims.
