Titles in the Core Text series take the reader straight to the heart of the subject, providing focused, concise, and reliable guides for students at all levels. This chapter examines potentially unfair terms, including exemption clauses, in a contract. It considers the common law’s response to exemption clauses and other potentially unfair terms, and discusses statutory schemes to regulate them. It covers the Unfair Contract Terms Act 1977 (UCTA) which governs exemption clauses in non-consumer contracts, subjecting them to a requirement of reasonableness where the contract was made on standard terms. It also discusses in detail the Consumer Rights Act 2015 (CRA), which imposes a test of fairness on terms in consumer contracts, apart from the core terms.
