Service catalogue

Our Service Catalogue is a list of services provided by IT Services to members of the University of ßÏßÏÊÓƵ and certain categories of visitors.

Each service within the catalogue typically includes a brief description of the service and how to access it, who is entitled to use/request the service, details of availability and service maintenance, and links to further information. This is intended to help improve knowledge within the University of the range of services we currently provide and to help users get more out of them. The range of services offered is reviewed annually with the University IT Consultative Group.
