Can acceptance to an offer be by conduct under English law?

Yes, under English law, acceptance to an offer can be by conduct. English contract law recognizes that in some circumstances, conduct between the parties can be considered an acceptance of an offer, leading to the formation of a contract even without an express agreement. The principle that acceptance can be by conduct is based on the idea that parties can enter into a binding agreement through their actions, even if they do not make an express agreement. In such cases, the court will look at the parties´ conduct and determine whether it constitutes an acceptance of an offer, and if so, a contract will be inferred. Examples of conduct that can constitute acceptance include the performance of an act requested by the offeror, or the conduct of the parties that demonstrates a mutual understanding to be bound by a contract.
