Boulton was widely involved in civic activities in Birmingham. His friend Dr John Ash had long sought to build a hospital in the town. A great fan of the music of Handel, Boulton conceived of the idea to hold a music festival in Birmingham to raise funds for the hospital. The festival took place in September 1768, the first of a series stretching well into the twentieth century. The hospital, Birmingham General, opened in 1779. Boulton also helped build the General Dispensary, where outpatient treatment could be obtained. A firm supporter of the Dispensary, he served as treasurer, and wrote, "If the funds of the institution are not sufficient for its support, I will make up the deficiency." The Dispensary soon outgrew its original quarters, and a new building in Temple Row was opened in 1808, shortly before Boulton's death.
