Construction disputes do not always emerge while work is underway. Defects may remain hidden for years, while disagreements over design, workmanship or professional advice can surface long after a project has been completed. By then, the question may be not only whether you have a valid claim, but whether you still have time to pursue it.
Under English law, statutory limitations set deadlines for bringing different types of legal claims. For construction disputes, the relevant period will depend on factors including the cause of action, when that cause of action arose and whether the contract was executed as a simple contract or a deed.
These distinctions matter because limitation can provide a complete defence to an otherwise valid claim. Calculating the deadline correctly at an early stage can therefore be just as important as establishing who was responsible for the underlying problem.
In this article, we explain the main limitation periods affecting construction claims, when time starts running and where problems commonly arise.
What Limitation Periods Are and Why They Matter
A limitation period is the period within which you must commence legal proceedings for a particular claim. Once that period has expired, the defendant may argue that the claim is time-barred. Limitation operates as a defence, so the court does not automatically prevent an out-of-time claim from proceeding.
This is particularly important in construction because the events giving rise to a dispute and the discovery of the problem can be separated by several years. For example, defective foundations might be installed during construction but only become apparent when cracking or subsidence develops much later.
It is also easy to confuse a contractual defects liability period with the legal limitation period. The end of a 12 or 24-month defects period does not necessarily end a contractor’s potential liability. The applicable statutory limitation period may continue for considerably longer. The practical difficulty is therefore being able to establish which limitation period applies and the date from which it should be calculated.
The Legal Framework Behind Limitation Periods
The main legislation governing statutory limitations in construction claims is the Limitation Act 1980. It establishes the time limits for claims including breach of contract and negligence, although other legislation can alter the position for particular types of construction claim.
The legal framework can therefore involve several pieces of legislation. The Defective Premises Act 1972 creates duties relating to certain work on dwellings, while the Building Safety Act 2022 significantly extended the limitation periods for some claims under that Act. These changes are particularly important for defects affecting residential buildings and some historic projects.
Separate rules also apply where one party seeks a contribution from another party responsible for the same damage. This can be important in construction disputes involving several contractors, consultants or other members of the project team.
The applicable legislation is therefore determined by the legal basis of the claim, rather than simply by the fact that the dispute relates to construction. We will look at the principal periods that result from these rules next.
The Main Limitation Periods in Construction Claims
The limitation period for a construction claim depends primarily on the legal basis of the claim. For most disputes, the starting point is to determine whether you are claiming for a breach of contract, negligence or a contribution towards liability owed to another party.
Contract Claims
For breach of contract, you generally have six years from the date of breach to bring a claim where the agreement is a simple contract. If the contract was executed as a deed, the period is generally 12 years from the date of breach.
This distinction is an important part of the statute of limitations UK contract law framework for construction projects. Whether a contract is a deed can effectively double the period available, making the way the agreement was executed important when assessing an older claim.
Negligence Claims
Claims in negligence generally have a six-year limitation period from when the cause of action accrues. Where physical damage has occurred, this is generally when the damage occurs, rather than when you later discover it.
However, special provisions can apply to latent damage that was not immediately apparent. Section 14A of the Limitation Act 1980 may provide an alternative period of three years from the relevant date of knowledge. We look at this in more detail below.
Contribution Claims
A party that is liable for damage may sometimes seek a contribution from another party that is also responsible. Under the Civil Liability (Contribution) Act 1978, the limitation period for such a claim is generally two years from the date on which the underlying liability is established by judgment, award or agreement.
This can become important where liability passes through a contractual chain involving an employer, main contractor, subcontractors and consultants.
When Does Time Start Running?
The limitation period does not necessarily start when the project reaches practical completion or when you first discover a problem. The relevant date depends on the legal basis of your claim, and identifying it incorrectly could mean calculating the deadline several years too late.
For a breach of contract claim, time generally starts when the breach occurs. In construction, that could be when defective work is carried out or when a contractual obligation should have been performed. The precise date will therefore depend on the obligation that has allegedly been breached.
For a negligence claim, the position is different. Where the negligence causes physical damage, the cause of action generally accrues when that damage occurs. The date on which you become aware of the damage is not necessarily the same date.
This distinction can become contentious when work took place over an extended period or the defect only became apparent much later. Rather than assuming time started at completion or discovery, the alleged breach or damage must be identified and the limitation period calculated from the legally relevant date.
Latent Defects and the “Date of Knowledge”
A latent defect is a defect that existed when construction was completed but was not apparent at the time. It might result from defective design, materials or workmanship and only become evident several years later. This makes latent defects construction law particularly important when considering limitation periods.
For negligence claims involving latent damage, section 14A of the Limitation Act 1980 provides an alternative limitation period where the ordinary six-year period has expired. A claimant may have three years from the earliest date on which they had the knowledge required to bring the claim and the right to bring it.
Importantly, this is not simply three years from discovering that something is wrong. The required knowledge includes knowing that the damage is sufficiently serious and that it is attributable, at least in part, to the act or omission alleged to constitute negligence.
The Vinci Construction UK Limited v Eastwood and Partners (Consulting Engineers) Limited & Anor [2023] EWHC 1899 (TCC) case illustrates how difficult this can be in practice. Although the parties were aware of sufficiently serious damage by March or April 2015, the court could not determine at summary judgment when Snowden had sufficient knowledge that the damage was attributable to GHW’s alleged negligence. The question therefore had to be determined at trial.
There is also an overriding 15-year longstop under section 14B, calculated from the defendant’s negligent act or omission. This means the date-of-knowledge provisions cannot indefinitely extend the construction defect statute of limitations.
The Latent Damage Act limitation provisions can therefore provide additional time in some negligence claims, but they should not be treated as an automatic extension. Establishing when you had, or reasonably should have had, the necessary knowledge can itself become a disputed issue.
Contract vs Deed: Why it Changes Everything
Whether a construction contract is executed as a simple contract or a deed can make a significant difference to limitation. A claim for breach of a simple contract generally has a six-year limitation period, while a contract executed as a deed generally allows 12 years.
This makes execution more than an administrative detail. On projects with long contractual chains, different appointments, subcontracts and warranties may not all have been executed in the same way. The result can be different contractual limitations for claims arising from the same underlying defect.
Lendlease Construction (Europe) Ltd v AECOM Ltd [2023] illustrates why execution matters. AECOM argued that its consultancy agreement had not been validly executed as a deed and that the six-year limitation period therefore applied, which would have left Lendlease’s entire claim time-barred. The court ultimately held that AECOM was prevented from denying that the agreement operated as a deed in the circumstances, meaning the 12-year limitation period applied. The claim ultimately failed on different grounds.
When investigating an older construction dispute, it is therefore important to check the executed documents themselves rather than assuming that every party in the contractual chain has the same period available.
Can Limitation Periods Be Changed by Contract?
Parties can agree contractual limitations that alter the period within which claims may be brought. For example, a contract may shorten the period that would otherwise apply under the Limitation Act 1980. However, whether such a provision is enforceable will depend on its wording and may also be subject to statutory controls on unreasonable contract terms.
Clear drafting is particularly important. A limitation clause should make it apparent how long the agreed period lasts, what triggers it, which claims it covers and what a party must do before the deadline expires. Ambiguous wording can create a separate dispute over whether the clause applies at all.
Problems can also arise where limitation provisions are inconsistent across the project’s contractual chain. An employer, contractor and consultant may have different periods applying to closely related liabilities, potentially leaving one party exposed without an equivalent route to recover its loss from another.
For this reason, limitation provisions should be considered alongside the wider contractual structure rather than reviewed in isolation. On complex projects, aligning relevant periods can help reduce gaps in liability and recovery rights.
The Impact of the Building Safety Act 2022
The Building Safety Act 2022 significantly extended the limitation periods for certain claims involving defective residential buildings. Most notably, it changed the periods applying to claims under the Defective Premises Act 1972, meaning some claims relating to historic projects that were previously time-barred may now be capable of being pursued.
- For claims under section 1 of the Defective Premises Act 1972, which concerns work connected with the provision of a dwelling, the position depends on when the work was completed:
- Work completed before 28 June 2022: the limitation period was extended retrospectively from six years to 30 years.
- Work completed on or after 28 June 2022: a 15-year limitation period applies.
The Act also introduced section 2A of the Defective Premises Act, extending duties to certain work on existing dwellings, such as refurbishment. Claims under this provision have a 15-year limitation period, but the provision applies prospectively rather than retrospectively.
These changes can make historic projects worth revisiting. However, the longer periods do not apply to every construction defect or automatically extend ordinary contract and negligence claims. You first need to establish whether the particular cause of action falls within the legislation and then calculate the applicable period accordingly.
Overlapping Claims: Contract vs Tort
A construction defect may potentially give rise to claims in both contract and tort. For example, defective professional services could amount to a breach of contractual obligations while also giving rise to a claim in negligence. However, the availability and limitation period of each claim must be considered separately.
This can matter where the contractual limitation period has expired but a negligence claim may still be available, particularly where latent damage provisions apply. It does not, however, mean that a claimant can simply reframe a time-barred contractual claim in negligence to obtain more time.
Whether a duty of care exists in tort, what losses it covers and when the cause of action accrued all require separate consideration. The contract itself may also restrict the duties or remedies available.
Where both routes appear possible, each should therefore be assessed on its own facts rather than treating tort as an automatic way around an expired contractual limitation period.
Common Pitfalls in Construction Claims
Limitation problems often arise not because a party is unaware that a deadline exists, but because the wrong deadline has been calculated. In construction disputes, several dates and limitation periods may be relevant to the same underlying defect.
Common mistakes include assuming that time starts at practical completion rather than identifying the actual date of breach, or treating the date a defect was discovered as the starting point for a negligence claim. Another is assuming that every agreement in the contractual chain has a 12-year limitation period without checking whether each document was actually executed as a deed.
Parties can also lose time while investigating defects, exchanging correspondence or negotiating a resolution. Those discussions do not necessarily stop the limitation clock. A standstill agreement may suspend time while negotiations continue, but it cannot revive a claim for which the limitation period has already expired.
These issues can be decisive. A strong claim supported by technical evidence may still fail if proceedings are commenced too late, making limitation one of the first issues to investigate rather than something to consider once the dispute has developed.
Practical Takeaways
Limitation should be considered as early as possible when a construction dispute emerges. Even if the underlying facts are still being investigated, establishing the potential deadline can prevent an otherwise viable claim from becoming time-barred.
Start by identifying the legal basis of each potential claim and checking how the relevant contract, appointment or warranty was executed. Do not assume that every agreement within the project has the same limitation period simply because the documents relate to the same works.
The next step is to identify the correct accrual date. Depending on the claim, this might be the date of breach, the date damage occurred or, where the statutory provisions for latent damage apply, the relevant date of knowledge. Where several dates are arguable, it is prudent to work from the earliest potentially applicable deadline.
If that deadline is approaching, negotiations should not be allowed to continue without considering how to protect your position. This may involve agreeing a standstill with the other party or issuing protective proceedings while the dispute is investigated.
The key is not to wait until every aspect of the claim has been resolved before considering limitation. Establishing the relevant period and calculating the deadline early gives you more time to investigate the merits of the claim and decide how best to proceed.
