A “contract without consideration” is a term used in contract law, which refers to an agreement that is not supported by any consideration, or a promise that is not made in exchange for something of value. In the United Kingdom (UK), such contracts are generally unenforceable.

In order for a contract to be enforceable, it must meet certain legal requirements. One of those requirements is that there must be consideration, which is defined as something of value that is given or promised in exchange for a promise. Consideration can be anything from money to goods, services, or even promises.
A contract without consideration is essentially a promise made without any exchange of value. For example, if someone promises to wash your car for free, but does not receive anything in return or provide any other service or product, this is a contract without consideration.
In the UK, contract law is governed by common law principles. These principles require that for a contract to be legally binding, it must have several essential elements, such as an offer, acceptance, and consideration. While consideration is not always required in every type of contract, it is a crucial element in most types of agreements.
In some cases, however, courts have recognized certain types of promises that are made without consideration. For example, promises of gifts, charitable contributions, or moral obligations may be enforceable.
Furthermore, the law recognizes that there may be situations where the parties intended to create legally binding obligations, even if there is no consideration. In these cases, the courts may still enforce the contract, based on the parties’ intentions and other surrounding circumstances.
Overall, a contract without consideration in the UK is generally unenforceable, unless certain exceptions apply, such as promises of gifts or charitable contributions. As such, it is important to ensure that any agreements you enter into are supported by consideration, to avoid potential legal disputes down the line.
