The limitation of liability clause is usually the last thing negotiated and the first thing litigated. It sits near the back of the contract, gets skimmed in the rush to signature, and then becomes the single most important provision the day a project fails and someone counts the cost. A cap set too low leaves a wronged party under-compensated; one drafted carelessly may not hold at all. And there are things UK law simply won't let you exclude, no matter how the clause is worded.
Here's how a limitation of liability clause is constructed, illustrative wording, and — the part that catches people out — the legal limits on what it can actually do.
What the clause does
A limitation of liability clause allocates the risk of things going wrong. It does two related jobs:
- Caps the total amount one party can be liable for (often by reference to fees paid, or a fixed sum).
- Excludes certain types of loss altogether (commonly indirect or consequential loss, loss of profit, loss of data).
The commercial logic is that a supplier charging £50,000 for a project cannot sensibly accept unlimited exposure for a failure that might cause a customer millions in downstream losses. The clause makes the risk proportionate to the deal — which is legitimate, and expected, in business-to-business contracts.
The building blocks
Most limitation clauses are assembled from the same components. Reading one means checking each:
- The overall cap. A figure or a formula — frequently "the total fees paid in the [12] months preceding the claim." Watch whether it's aggregate (one cap for everything) or per-claim.
- Excluded losses. Categories carved out entirely — indirect and consequential loss, loss of profit, revenue, goodwill, data. The precise words matter; "consequential loss" has a narrower legal meaning than most people assume.
- Carve-outs from the cap (the "super-cap" or unlimited items). Liabilities deliberately left uncapped — typically breach of confidentiality, data protection breaches, IP infringement, and the items the law won't let you limit (below).
- Mutuality. Whether the cap applies to both parties or just one. A one-sided cap is a red flag worth challenging.
Field note: "Consequential loss" is the most misunderstood phrase in the clause. Under English law it has been read narrowly — losses falling under the second limb of the old Hadley v Baxendale rule — so excluding "consequential loss" often does not exclude the direct loss of profits a party actually cares about. If you mean to exclude lost profits, say "loss of profit" expressly; don't rely on "consequential."
Illustrative wording
Illustrative only — to show the structure, not for use as a precedent:
"Subject to clause [X.1], each party's total aggregate liability arising under or in connection with this Agreement, whether in contract, tort (including negligence) or otherwise, shall not exceed [the total Charges paid in the 12 months preceding the event giving rise to the claim]. Neither party shall be liable for any loss of profit, loss of revenue, or loss of data, or for any indirect or consequential loss. Clause [X.1]: Nothing in this Agreement limits or excludes liability for death or personal injury caused by negligence, for fraud or fraudulent misrepresentation, or for any liability that cannot lawfully be limited or excluded."
That final carve-out clause isn't optional politeness — it's doing legally required work, as the next section explains.
The limits the law imposes
This is where limitation clauses fail, and where a lot of drafting is quietly non-compliant. In the UK, you cannot exclude or limit certain liabilities, and other limitations only stand if they're reasonable.
- You cannot exclude liability for death or personal injury caused by negligence. Under the Unfair Contract Terms Act 1977, this is void. Every well-drafted clause carves it out expressly.
- You cannot exclude liability for fraud or fraudulent misrepresentation. The law won't enforce an attempt to contract out of your own fraud.
- Business-to-business limitations are subject to a reasonableness test. The Unfair Contract Terms Act 1977 subjects many exclusions and limitations to a requirement of reasonableness — and a clause found unreasonable is unenforceable, potentially leaving the party with no protection at all. A cap that's derisory relative to the contract value, or buried and never negotiated, is vulnerable.
- Consumer contracts are stricter still. The Consumer Rights Act 2015 governs terms with consumers, and many limitations that work business-to-business won't survive against a consumer.
The practical consequence: an over-aggressive clause can be worse than a moderate one, because failing the reasonableness test can strike the limitation down entirely rather than reading it down to a reasonable level.
What to negotiate
- If you're the supplier: push for an aggregate cap tied to fees, exclude indirect loss and name loss of profit expressly, and keep the super-cap items as narrow as the deal allows — while always carving out the non-excludable liabilities so the clause stays enforceable.
- If you're the customer: challenge a one-sided cap, negotiate the quantum up (a 12-month-fees cap can be trivial against real exposure), and insist on uncapped or higher-capped liability for confidentiality, data protection, and IP breaches.
- If you're reviewing at speed: check three things first — is death/personal injury and fraud carved out, is the cap mutual, and does "consequential loss" carry the weight someone thinks it does?
Where AI contract tools help
Limitation of liability is a clause an AI contract review tool reliably finds and summarises — extracting the cap, the excluded losses, and whether it's mutual, and flagging deviations from your firm's standard. That's a real first-pass saving on a provision that's easy to skim past.
What AI won't reliably judge is whether the clause is reasonable under UCTA in the specific commercial context, or whether the loss the client actually fears is caught by the exclusions — that's legal judgement on the facts. And because summaries flatten nuance, the "consequential loss" trap is exactly the kind of thing to verify by reading the clause, not the AI's description of it.
FAQ
What is a limitation of liability clause? A clause that caps the total amount a party can be liable for and excludes certain types of loss, allocating the risk of things going wrong so exposure is proportionate to the deal.
Can you exclude all liability in a contract? No. Under UK law you cannot exclude liability for death or personal injury caused by negligence, or for fraud, and many other limitations only stand if they are reasonable under the Unfair Contract Terms Act 1977.
What does "consequential loss" actually exclude? Less than most assume. Under English law it has been read narrowly, so excluding "consequential loss" may not exclude the direct loss of profit a party cares about. Name loss of profit expressly if that's the intention.
What is a typical liability cap? Commonly the total fees paid over a set period (often 12 months) or a fixed sum, sometimes with higher or unlimited "super-caps" for confidentiality, data, or IP breaches. There's no universal figure; it's negotiated against the deal's value and risk.
Can an over-aggressive limitation clause backfire? Yes. If a limitation fails the reasonableness test under UCTA, it can be struck down entirely, potentially leaving the party with no protection rather than a reduced one. A defensible, moderate clause can be safer than an aggressive one.
