A liability cap limits how much the service provider will pay you if things go wrong. In UK business-to-business agreements, these caps are common and often set well below the actual loss you could suffer. In consumer contracts, many liability exclusions are simply unlawful. Understanding what the cap covers, what it excludes, and whether it reflects realistic risk is one of the most important things to check before you sign.
What is a Liability Cap?
A liability cap is a contractual ceiling on the financial compensation one party can claim from the other. In service agreements, it typically limits the provider's total liability to a multiple of the fees paid (e.g., 100% or 12 months' fees). Caps are often paired with exclusion clauses that exclude consequential losses, lost profits, and indirect losses entirely — meaning the cap only applies to direct losses, and even those are limited.
Red flags to watch for
If the service fails and causes significant loss, a cap equivalent to the contract value may be a fraction of your actual damages. Consider whether the cap reflects realistic worst-case exposure.
In many service failures, the majority of loss is indirect — lost clients, lost revenue, business interruption. An exclusion of consequential loss could mean the provider pays almost nothing for a serious failure.
Some contracts cap liability even for fraud, wilful misconduct, or death and personal injury. Under UK law (UCTA 1977), liability for negligence causing death or personal injury cannot be excluded.
If the cap applies to both parties equally, but the provider's obligations are the primary ones, you may find the cap restricts your claims while your payment obligations remain uncapped.
These claim types often produce the largest losses. Many providers exclude the cap for these claims when they are the claimant, but not when you are claiming against them.
Your legal rights
The Unfair Contract Terms Act 1977 (UCTA) applies to business contracts and prohibits exclusion of liability for negligently caused death or personal injury. Exclusion of other loss from negligence is subject to a reasonableness test. For consumer contracts, the Consumer Rights Act 2015 provides much stronger protections: terms that exclude liability for poor service, inaccurate descriptions, or goods not of satisfactory quality are unenforceable. The test is whether the term is fair and transparent.
