 Van Mildert had arranged for the bishop's residence to be moved to Auckland Castle in 1832 in order for the University to occupy Durham Castle as University College, Durham in 1837; by that time, Maltby had arranged to make the necessary renovations.The Established Church Act 1836 set the maximum annual income for a bishop at £8,000 (£525,000 at 2003 prices) but it was revealed in 1847 that Maltby was earning around £12,000 (£787,000), having exceeded £21,000 (£1.4 million) in 1841.In response to the widespread public criticism, he established the Maltby Fund for building work in the Durham diocese.
