At the age of 28, Jeri Cormack is the UK's youngest retained lighthouse keeper.

She is one of 17 part-time keepers working for the Northern Lighthouse Board, tasked with looking after the network since its automation in the 1990s.

Tackling often fierce weather, Jeri inspects and maintains three historic lighthouses at the edge of the British mainland - Noss Head, Dunnet Head and Duncansby Head.
