Castle Point Borough Council counts over 120 stores across the Canvey town centre, mainly independent sector, with national chains such as Boots, Iceland and Sainsbury's. For a town of 38,000 that is an exceptionally independent-heavy retail base.
Energy and storage is the island's industrial backbone: Britain's first ship delivery of liquefied natural gas landed at Hole Haven on 20 February 1959, and Calor Gas (LPG import/export) and Oikos Storage, on the island for over seventy years, still operate on the former terminal sites. The wider trading estate economy centres on Charfleets Industrial Estate.
Marine trades matter here, Smallgains Creek has its own boatyards, and the island was long home to Prout's Catamarans, a boat-building firm.
Canvey sits below sea level and its identity is bound up with the 1953 North Sea flood, which killed 58 islanders; roughly 15 miles of modern sea defences were completed by 1982 and the sea wall at Concord Beach now carries murals telling that story.
Canvey Island had a recorded population of about 38,327 at the 2021 census.
