Does acceptance be communicated to the offeror in order to be accepted under English law?

Yes, under English law, acceptance of an offer must be communicated to the offeror in order to be valid. A contract is formed when the acceptance of an offer is communicated to the offeror and the offeror has notice of the acceptance. The communication of acceptance can be express, such as a written or oral statement, or it can be implied through the conduct of the parties. Until the acceptance is communicated to the offeror, the offer remains open and can be revoked by the offeror. Once the acceptance is communicated and the offeror has notice of it, a contract is formed and the parties are bound by its terms.
