Heminges remained active in the Grocers' Company alongside his theatrical activities; indeed, the two sometimes intertwined. On 13 December 1608 he was admitted as one of the ten seacoal-meters for the city of London, citizens appointed to measure the coal imported into the city by sea. Shortly afterwards he took on John Jackson as his deputy. Both Heminges and Jackson later acted as trustees for William Shakespeare when he purchased the Blackfriars Gatehouse in 1613. Between 1595 and 1628 Heminges took on ten apprentices with the Grocers' Company. Of these ten, eight appear to have performed for Heminges's company, in both boys' and adult roles. Alexander Cooke was one of his apprentices. Heminges also built and operated a taphouse at the Globe.
