Contracts
Liquidated damages, caps and termination
Liquidated damages are a pre-agreed rate for late completion. They are not an automatic debt, and the clause has prerequisites that are regularly ignored by both parties.

What the clause does
It fixes the employer’s remedy for late completion at a stated rate, removing the need to prove actual loss. That certainty runs both ways: it caps the contractor’s exposure for delay at the stated rate, and it usually excludes a general damages claim for the same lateness.
The prerequisites
- A valid completion date, which means every due extension has been assessed.
- Whatever certificate, notice or withholding step the contract requires before deduction.
- A rate that has been correctly stated in the contract particulars, including where it is nil.
A rate stated as nil is a common trap, and its effect depends on the wording and the jurisdiction. It may exclude delay damages entirely, or it may leave the employer to general damages. That is a question for the contract and for advice.
Enforceability
The tests differ by jurisdiction. In England and Wales the modern approach asks whether the clause imposes a detriment out of all proportion to a legitimate interest in enforcement, rather than applying an older genuine pre-estimate test mechanically. Elsewhere, statutory or code provisions may permit adjustment of an agreed sum. Do not carry a rule across a border.
Termination
Judgment Triple Point Technology Inc v PTT Public Company Ltd [2021] UKSC 29 addressed the position of liquidated damages accrued up to termination, and is the modern starting point in the United Kingdom. Its application always returns to the specific clause.
Caps
A delay damages cap, an overall liability cap and an exclusion of consequential loss are three different provisions that frequently sit in the same contract and are frequently read as one. Check whether the delay cap sits inside or outside the overall cap, and what happens when it is exhausted.

Where the record comes in
Every mechanism on this page turns on evidence: what happened, what was known and when. A record built as the job happens is worth more than any argument assembled afterwards. Construction Metric keeps that record automatically, from the messages, photographs and voice notes a site team already sends.

The analysis on this site is only as fast as the evidence behind it. AI Metric builds bespoke systems for consultancies, contractors and claims teams: document and correspondence triage, event registers assembled from the project record, programme and cost reconciliation, and drafting support that always cites the document it came from. Built for review by your own experts, never to replace their judgement.
Do not overread this page
Enforceability, deduction mechanics and the effect of termination all vary by jurisdiction and by clause. Never treat a liquidated damages clause as an automatic debt without checking its prerequisites.
