Liability caps in UK T&Cs: what survives a challenge

Limiting your liability is the grown-up part of writing T&Cs. Without a
cap, you're theoretically on the hook for every imaginable loss. With a
badly written cap, you're on the hook and your clause might get thrown
out as unfair. UK law doesn't mind you protecting yourself, but it does
insist on reasonableness, especially in consumer contracts.

The legal backdrop

In business-to-business contracts, UCTA
1977 polices exclusion and limitation clauses using a "reasonableness" test.
In consumer contracts, CRA
2015 adds much stricter controls, particularly around attempts to exclude
statutory rights or cap liability in ways that create a significant
imbalance. Excluding liability for death or personal injury caused by
negligence is banned outright.

Typical cap structures

Most sensible T&Cs use one of a few patterns:

• A cap linked to the fees paid or payable under the contract.

• A cap linked to a multiple of those fees.

• A cap aligned with the trader's insurance limit.

• A fixed-sum cap for small, low-risk contracts.

The clause then lists categories of loss that are excluded, such as loss
of profits or data, while preserving liability for things that legally
can't be
excluded.

What gets thrown out

Caps that attempt to exclude all liability, or that are wildly
disproportionate to the transaction, are prime candidates for being
struck down as unfair, particularly in consumer contracts. CRA
guidance makes it clear that terms undermining core rights can be challenged.
Courts and regulators are unimpressed by microscopic caps buried in the
small print.

Balancing risk and reality

A sensible cap should reflect the size of the deal, your ability to
insure against it and the practical risk profile of your work. You
cannot design a clause that magically removes all risk; you can design
one that keeps claims in a predictable band if something genuinely goes
wrong.

How the generator approaches caps

The Trading Terms generator offers a handful of cap options and aligns the
wording with UK reasonableness expectations. You pick the level that
fits your business, and the document inserts the right exclusions and
carve-outs. It won't let you pretend you're immune from liability, but
it will help you avoid accidentally promising a blank
cheque.
