Contracts are an essential part of our daily lives, and they help govern business relationships, financial agreements, and even personal transactions. However, not all contracts are created equal, and some may contain specific terms and conditions that limit your options and restrict your choices. One such term is the “lock-in” clause. In this article, we will explain what a lock-in contract is, how it differentiates from a non-lock-in contract, and what you should look out for when entering into a contract.
What is a Lock-In Contract?
A lock-in contract is a type of agreement that restricts the parties from ending or altering the contract for a specified period. This term is also known as a “minimum term” or “fixed term” and is common in contracts for services such as:
- gym memberships;
- telecommunications; or
- rental agreements.
For example, if you sign a lock-in contract with a gym for 12 months, you will be bound to pay the monthly fees for the entire year, even if you no longer want to use the gym or have a change in circumstances that prevent you from doing so. Similarly, suppose you sign a lock-in contract with a telecommunications provider for 24 months. In that case, you must pay the monthly fees and fulfil the contract terms for the entire two years, even if you find a better deal or switch providers.
How Does a Lock-In Contract Differ from a Non-Lock-In Contract?
A non-lock-in contract, also known as an “open term” or “periodic term,” is an agreement with no fixed duration and allows either party to terminate or modify the contract at any time without incurring penalties or fees. This type of contract is more flexible and allows the parties to change the terms of the agreement based on their needs or circumstances.
For example, signing a non-lock-in contract with a gym can cancel the membership anytime without incurring penalties or fees. Similarly, suppose you sign a non-lock-in contract with a telecommunications provider. In that case, you can switch to a different plan or provider without being bound to a fixed duration or paying early termination fees.

The unfair contract term regime has important implications for lock-in contracts. It makes unfair terms unenforceable, and soon penalties will apply to including unfair contract terms in standard form contracts. Under the unfair contract terms regime, a lock-in period in a contract will be unfair if it:
- disproportionately limits a consumer’s rights; or
- imposes an undue burden on them.
For example, suppose a lock-in contract automatically renews without giving the consumer a reasonable notice period to cancel. Such a contract may be considered unfair. Ultimately, any provision in a lock-in contract that unfairly disadvantages the consumer may be subject to challenge and potential penalty under the updated regime.
Under the updated regime, consumers can be confident they are protected against unfair contract terms. However, it is essential to read and understand the terms of any contract before signing. Consumers should also seek legal advice if they believe a lock-in contract contains unfair terms.
What to Look Out for in Your Contract
Before signing any contract, it is essential to read the terms and conditions carefully and understand the implications of any lock-in clauses or fixed terms. Here are some tips on what to look out for.
1. Duration
Check the length of the fixed term and determine whether it suits your needs and circumstances. If you are unsure, consider negotiating a shorter term or opting for a non-lock-in contract.
2. Early Termination
Check the penalties or fees associated with terminating the contract before the fixed term ends. Consider negotiating a lower rate or opting for a non-lock-in contract if the fees are high.
3. Renewal
Check whether the contract automatically renews at the end of the fixed term and whether you need to take any action to cancel or modify the agreement.
4. Price
Check whether the contract price is fixed for the entire duration or subject to change. If the price can change, check how and when it can be changed and whether you have the option to terminate the contract if the price increases.
