Penalty Clauses in UK Agreements

Penalty clauses are contractual provisions that require one party to pay a specified sum or suffer a financial consequence if they breach the contract.

Under English law, penalty clauses are generally unenforceable if they are designed to punish the defaulting party rather than protect a legitimate commercial interest.

The historical position

Traditionally, the courts distinguished between:

• Liquidated damages clauses, which represent a genuine pre-estimate of loss and are generally enforceable; and
• Penalty clauses, which impose an excessive or punitive consequence for breach and are unenforceable.

The current position

The leading authority is the Supreme Court decision in Cavendish Square Holding BV – v –  Makdessi and ParkingEye Ltd v Beavis. In that case, the Court reformulated the test and held that the key question is whether the clause imposes a detriment that is out of proportion to the innocent party’s legitimate interest in enforcing the contract.

As a result, a clause no longer needs to be a precise estimate of loss to be enforceable. Businesses may have legitimate interests extending beyond simple compensation, such as protecting goodwill, confidential information, customer relationships, or ensuring timely performance of a project.

In commercial contracts, common examples of potentially enforceable provisions include:

• Delay damages in construction contracts;
• Service credits in outsourcing agreements;
• Earn-out adjustments in business sales; and
• Retentions or deductions linked to performance obligations.

Conversely, a clause is more likely to be unenforceable where it requires payment of a disproportionately large sum for a relatively minor breach, or where its primary purpose is to deter breach rather than protect a legitimate contractual interest.

Conclusion

English law does not prohibit contractual consequences for breach, but it will not enforce provisions that operate as penalties. The focus is on whether the clause protects a legitimate interest and whether the detriment imposed is proportionate to that interest.

For businesses drafting contracts, the best practice is to ensure that any financial consequences of breach can be objectively justified and are proportionate to the commercial risks involved. Careful drafting can significantly improve the likelihood that the provision will be upheld by the courts.
