Returning to the original question, university chancellors' are by and large, ceremonial figureheads that are usually paid nominal fees for expenses etc but cannot be regarded as salaried.
Some of the more famous UK universities have chancellors' that are famous from the public domain and are typically well known industrialists, diplomats, bankers or have served in government etc. Members of the House of Lords are quite prevalent amongst them.
Younger universities tend to have chancellors who are amongst the "great and the good" in the locality. I attended and spoke at a graduation ceremony in the Midlands area a few months ago where the Chancellor was a famous landowner in the area: in fact, a village down the road from the university was virtually entirely owned by his family and was part of the estate. I was not surprised when I was invited to the vice-chancellor's home later that day that he/she lived in the village concerned. Ah, twas ever thus.
