An express agreement is an exchange of promises in which the terms by which the parties agree to be bound are declared.
In principle, the pre-contract information given to students at the offer stage should still be accurate on enrolment. In any event, if it has been necessary to make any changes that affect material information, the changes must be communicated to the affected students at the earliest opportunity.
Express agreement from applicants that have submitted an application but have not yet accepted the offer is normally sought via email outlining the proposed changes.
When making changes that will affect any prospective students who have accepted an offer and those that have enrolled, a consultation stage would normally be required.
