AMSAT-UK is a wholly voluntary club. All its officers and members do any work on a purely voluntary basis. AMSAT-UK has no paid employees, and is run solely to support its members in their pursuit of their hobby of amateur radio space activities. It does not undertake any commercial activities.

Members are asked to make a small annual donation to cover the expenses of running the club, mainly the production and distribution of Oscar News, a quarterly newsletter sent to all members. Any money that is surplus is used to support the Amateur Satellite Service as defined by the ITU.
